Definition of Terms 1.02 Contract Documents grncand/b.specem General Conditions of Agreement 1.01 Owner, Contractor and Engineer The Owner, the Contractor and the Engineer and those persons or organization identified as such in the Agreement and are referred to throughout the contract Documents as if singular in number and masculine in gender. The term Engineer means the Engineer or his duly authorized representative. The Engineer shall be understood to be the Engineer of the Owner, and nothing contained in the Contract Documents shall create any contractual or agency relationship between the Engineer and the Contractor. The Contract Documents shall consist of the Notice to Contractors, Instructions to Bidders, Proposal, Signed Agreement, Performance and Payment Bonds (when required), Special Bonds (when required), General Conditions of the Agreement, Construction Specifications, Plans and all modifications thereof incorporated in any of documents before the execution of the agreement. The Contract Documents are complementary, and what is called for by any one shall be as binding as if called for by all. In case of conflict between any of Contract documents, priority of interpretation shall be in the following order: Signed Agreement, Performance and Payment Bonds, Special Bonds (if any), Proposal, Special Conditions of Agreement, Notice to Contractors, Technical Specifications, Plans, and General Conditions of Agreement. 1.03 Subcontractor The term Subcontractor, as employed herein, includes only those having a direct contract with the Contractor and it includes one who furnishes material worked to special design according to the plans or specifications of this work, but does not include one who merely furnishes material not so worked. 1.04 Sub - subcontractor The term Sub - Subcontractor means one who has a direct or indirect contract with a sub- contractor to perform any of the work at the site and includes one who furnishes material worked to a special design according to the plans or specifications of this work, but does not include one who merely furnishes material not so worked. GC-4 1.05 Written Notice 1.06 Work geaeeudlb:specam Written notice shall be deemed to have been duly served if delivered in person to the individual or to an officer of the corporation for whom it is intended, or if delivered at or sent by registered mail to the last business address known to him who gives the notice. The Contractor shall provide and pay for all materials, machinery, equipment, tools, superintendence, labor, services, insurance, and all water, light, power, fuel, transportation and other facilities necessary for the execution and completion of the work covered by the contract documents. Unless otherwise specified, all materials shall be new and both workmanship and materials shall be of a good quality. The Contractor shall, if required, furnish satisfactory evidence as to the kind and quality of materials. Materials or work described in words which so applied have a well known technical or trade meaning shall be held to refer to such recognized standards. 1.07 Extra Work The term "Extra Work" as used in this contract shall be understood to mean and include all work that may be required by the Engineer or Owner to be done by the Contractor to accomplish any change, alteration or addition to the work shown upon the plans, or reasonably implied by the specifications, and not covered by the Contractor's Proposal, except as provided under "Changes and Alteration," herein. 1.08 Working Day A "Working Day" is defined as any day not including Saturdays, Sundays or any legal holidays, in which weather or other conditions, not under the control of the Contractor, will permit construction of the principal units of the work for a period of not less than seven (7) hours between 7:00 a.m. and 6:00 p.m. 1.09 Calendar Day "Calendar Day" is any day of the week or month, no days being excepted. 1.10 Substantially Completed By the term "substantially completed" is meant that the structure has been made suitable for use or occupancy or the facility is in condition to serve its intended purpose, but still may require minor miscellaneous work and adjustment. GC -5 2. Responsibilities of the Engineer and the Contractor 2.01 Owner - Engineer Relationship 2.02 Professional Inspection by Engineer The Engineer shall make periodic visits to the site to familiarize himself generally with the progress of the executed work and to determine if such work generally meets the essential performance and design features and the technical and functional engineering requirements of the Contract Documents; provided and except, however, that the Engineer shall not be responsible for making any detailed, exhaustive, comprehensive or continuous on -site inspection of the quality or quantity of the work or be in any way responsible, directly or indirectly, for the construction means, methods, techniques, sequences, quality, procedures, programs, safety precautions or lack of same incident thereto or in connection therewith. Notwithstanding any other provision of this agreement or any other Contract Document, the Engineer shall not be in any way responsible or liable for any acts, errors, omissions or negligence of the Contractor, any Subcontractor or any of the Contractor's or Subcontractor's agents, servants or employees or any other person, firm or corporation performing or attempting to perform any of the work. 2.03 Payments for Work gmcondlb•spccsm The Engineer will be the Owner's representative during construction. The duties, responsibilities and limitations of authority of the Engineer as the Owner's representative during construction are as set forth in the Contract Documents and shall not be extended or limited without written consent of the Owner and Engineer. The Engineer will advise and consult with the Owner, and all of Owner's instructions to the Contractor shall be issued through the Engineer. The Engineer shall review Contractor's applications for payment and supporting data, determine the amount owed to the Contractor and recommend, in writing, payment to Contractor in such amounts; such recommendation of payment to Contractor constitutes a representation to the Owner of Engineer's professional judgement that the work has progressed to the point indicated to the best of his knowledge, information and belief, but such recommendation of an application for payment to Contractor shall not be deemed as a representation by Engineer that Engineer has made any examination to determine how or for what purpose Contractor has used the moneys paid on account of the Contract price. GC -6 2.04 Initial Determinations gmccnd/b:spasm The Engineer initially shall determine all claims, disputes and other matters in question between the Contractor and the Owner relating to the execution or progress of the work or the interpretation of the Contract Documents and the Engineer's decision shall be rendered in writing within a reasonable time, which shall not be construed to be less than ten (10) days. Appeal to arbitration upon mutual agreement may be taken as if his decision had been rendered against the party appealing. 2.05 Objections In the event the Engineer renders any decision which, in the opinion of either party hereto, is not in accordance with the meaning and intent of this contract, either party may file with the Engineer within thirty (30) days his written objection to the decision, and by such action may reserve the right to submit the question so raised to arbitration as hereinafter provided. 2.06 Lines and Grades Unless otherwise specified, all lines and grades shall be furnished by the Engineer or his representative. Whenever necessary, construction work shall be suspended to permit performance of this work, but such suspension will be as brief as practicable and the Contractor shall be allowed no extra compensation therefor. The contractor shall give the Engineer ample notice of the time and place where lines and grades will be needed. All stakes, marks, etc., shall be carefully preserved by the Contractor, and in case of careless destruction or removal by him or his employees, such stakes, marks, etc., shall be replaced at the Contractor's expense. 2.07 Contractor's Duty and Superintendence The Contractor shall give adequate attention to the faithful prosecution and completion of this contract and shall keep on the work, during its progress, a competent English - speaking superintendent and any necessary assistants to supervise and direct the work. The superintendent shall represent the Contractor in his absence and all directions given to him shall be as binding as if given to the Contractor. The Contractor is and at all times shall remain an independent contractor, solely responsible for the manner and method of completing his work under this contract, with full power and authority to select the means, method and manner of performing such work, so long as such methods do not adversely affect the completed improvements, the Owner and Engineer being interested only in the result obtained and conformity of such completed improvements to the plans, specifications and contract. Likewise, the Contractor shall be solely responsible for the safety of himself, his GC -7 employees and other persons, as well as for the protection and safety of the improvements being erected and the property of himself or any other person, as a result of his operations hereunder. Engineering construction drawings and specifications as well as any additional information concerning the work to be performed passing from or through the Engineer shall not be interpreted as requiring or allowing Contractor to deviate from the plans and specifications, the intent of such drawings, specifications and any other such information being to define with specificity the agreement of the parties as to the work the Contractor is to perform. Contractor shall be fully and completely liable, at his own expense, for design, construction, installation and use, or non -use of all items and methods incident to performance of the contract, and for all loss, damage or injury incident thereto, either to person or property, including, without limitation, the adequacy of all temporary supports, shoring, bracing, scaffolding, machinery or equipment, safety precautions or devices, and similar items or devices used by him during construction. Any review of work in process, or any visit or observation during construction, or any clarification of plans and specifications, by the Engineer or Owner, or any agent, employee, or representative of either of them, whether through personal observation on the project site or by means of approval of shop drawings for temporary construction or construction processes, or by other means or method, is agreed by the Contractor to be for the purpose of observing the extent and nature of work completed or being performed, as measured against the drawings and specifications constituting the contract, or for the purpose of enabling Contractor to more fully understand the plans and specifications so that the completed construction work will conform thereto, and shall in no way relieve the Contractor from full and complete responsibility for the proper performance of his work on the project, including but not limited to the propriety of means and methods of the Contractor in performing said contract, and the adequacy of any designs, plans or other facilities for accomplishing such performance. Deviation by the Contractor from plans and specifications that may have been in evidence during any such visitation or observation by the Engineer, or any of his representatives, whether called to the contractor's attention or not shall in no way relieve Contractor from his responsibility to complete all work in accordance with said plans and specifications. 2.08 Contractor's Understanding gmeund/b:spccem It is understood and agreed that the Contractor has, by careful examination, satisfied himself as to the nature and location of the work, the conformation of the ground, the character, quality and quantity of the materials to be encountered, the character of equipment and facilities needed preliminary to and during the prosecution of the work, the general and local conditions, and all other matters which can in any way effect the work under this contract. The Contractor agrees that he will make no claim against the Owner or the Engineer if, in the prosecution of the work, he finds that the actual site or subsurface conditions encountered do not conform to those indicated by excavation, test excavation, test procedures, borings, explorations or other subsurface excavations. No GC -8 verbal agreement or conversation with any officer, agent or employee of the Owner or Engineer either before or after the execution of this contract, shall affect or modify any of the terms or obligations herein contained. 2.09 Character of Workers The Contractor agrees to employ only orderly and competent workers, skillful in the performance of the type of work required under this contract, to do the work; and agrees that whenever the Engineer shall inform him in writing that any workers on the work are, in his opinion, incompetent, unfaithful or disorderly, or refuse instructions from the Engineer in the absence of the Superintendent, such worker shall be discharged from the work and shall not again be employed on the work without the Engineer's written consent. No illegal alien may be employed by any Contractor for work on this project, and a penalty of $500.00 per day will be assessed for each day and for each illegal alien who works for the Contractor at this project. 2.10 Contractor's Buildings grncond/b:spccsm The building of structures for housing workers, or the erection of tents or other forms of protection, will be permitted only at such places as the Engineer shall direct, and the sanitary conditions of the grounds in or about such structures shall at all times be maintained in a manner satisfactory to the Engineer. 2.11 Sanitation Necessary sanitary conveniences for the use of laborers on the work, properly secluded from public observation, shall be constructed and maintained by the Contractor in such manner and at such points as shall be approved by the Engineer, and their use shall be strictly enforced. 2.12 Shop Drawings The Contractor shall submit to the Engineer, with such promptness as to cause no delay in his own work or in that of any other Contractor, four (4) checked copies, unless otherwise specified, of all shop and /or setting drawings and schedules required for the work of the various trades, and the Engineer shall pass upon them with reasonable promptness, making desired corrections. The Contractor shall make any corrections required by the Engineer, file with him two (2) corrected copies and furnish such other copies as may be needed. The Engineer's review of such drawings or schedules shall not relieve the Contractor from responsibility for deviations from drawings or specifications, unless he has in writing called the Engineer's attention to such deviations at the time of submission, nor shall it relieve him from responsibility for errors of any sort in shop drawings or schedules. It shall be the Contractor's responsibility to fully and completely review all shop drawings to ascertain their effect on his ability to perform GC -9 gcncood/b:spasm the required contract work in accordance with the plans and specifications and within the contract time. Such review by the Engineer shall be for the sole purpose of determining the general conformity of said shop drawings or schedules to result in finished improvements in conformity with the plans and specifications, and shall not relieve the Contractor of his duty as an independent contractor as previously set forth, it being expressly understood and agreed that the Engineer does not assume any duty to pass upon the propriety or adequacy of such drawings or schedules, or any means or methods reflected thereby, in relation to the safety of either person or property during Contractor's performance hereunder. 2.13 Preliminary Approval The Engineer shall not have the power to waive the obligations of this contract for the furnishing by the Contractor of good material, and of his performing good work as herein described, and in full accordance with the plans and specifications. No failure or omission of the Engineer to discover, object to or condemn any defective work or material shall release the Contractor from the obligations to fully and properly perform the contract, including without limitations, the obligation to at once tear out, remove and properly replace the same at any time prior to final acceptance upon the discovery of said defective work or material; provided, however, that the Engineer shall, upon request of the Contractor, inspect and accept or reject any material furnished, and in event the material has been once accepted by the Engineer, such acceptance shall be binding on the Owner, unless it can be clearly shown that such material furnished does not meet the specifications for this work. Any questioned work may be ordered taken up or removed for re- examination, by the Engineer, prior to final acceptance, and if found not in accordance with the plans and /or specifications for said work, all expense of removing, re- examination and replacement shall be borne by the Contractor, otherwise the expense thus incurred shall be allowed as Extra Work, and shall be paid for by the Owner; provided that, where inspection or approval is specifically required by the specifications prior to performance of certain work, should the Contractor proceed with such work without requesting prior inspection or approval he shall bear all expense of taking up, removing, and replacing this work if so directed by the Engineer. 2.14 Defects and Their Remedies It is further agreed that if the work or any part thereof, or any material brought on the site of the work for use in the work or selected for the same, shall be deemed by the Engineer as unsuitable or not in conformity with the plans, specifications, or the intent thereof, the Contractor shall after receipt of written notice thereof from the Engineer, forthwith remove such material and rebuild or otherwise remedy such work so that it GC -10 shall be in full accordance with this contract. 2.15 Changes and Alterations grnemd/6•spccsm The Contractor further agrees that the Owner may make such changes and alterations as the Owner may see fit, in the line, grade, form, dimensions, plans or materials for the work herein contemplated, or any part thereof, either before or after the beginning of the construction, without affecting the validity of this contract and the accompanying Performance and Payment Bonds. If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the basis for a claim for damages, or anticipated profits on the work that may be dispensed with, except as provided for unit price items under Section 5 "Measurement and Payment ". If the amount of work is increased, and the work can fairly be classified under the specifications, such increase shall be paid for according to the quantity actually done and at the unit price, if any, established for such work under this contract, except as provided for unit price items under Section 5 "Measurement and Payment "; otherwise, such additional work shall be paid for as provided under Extra Work. In case the Owner shall make such changes or alterations as shall make useless any work already done or material already furnished or used in said work, then the Owner shall recompense the Contractor for any material or labor so used, and for any actual loss occasioned by such change, due to actual expense incurred in preparation for the work as originally planned. 2.16 Inspectors The Engineer may provide one (or more) field inspectors at the work site for the limited purpose of observing the work in progress and reporting back to the Engineer on the extent, nature, manner and performance of the work so that the Engineer may more effectively perform his duties hereunder. Such inspectors may also communicate between Engineer and Contractor their respective reports, opinions, questions, answers and clarifications concerning the plans, specifications and work but shall be deemed the agent of the Contractor for all purposes in communicating such matters. Such inspector may confer with the Contractor or Contractor's superintendent concerning the prosecution of the work and its conformity with the plans and specifications but shall never be, in whole or part, responsible for, charged with, nor shall he assume, any authority or responsibility for the means, methods or manner of completing the work or of the superintendence of the work or of the Contractor's employees. It is expressly understood and agreed that any such inspector is not authorized by the Engineer or Owner to independently act for either or answer on behalf of either, any inquiries of the Contractor concerning the plans, specifications or work. No inspector's opinion; advice; interpretation of the plans or specifications of this contract; apparent or express approval of the means, methods or manner of Contractor's performance of work in progress or completed; or discovery or failure to discover or object to defective work of materials GC -11 geocond/b:apecam shall release Contractor from his duty to complete all work in strict accordance with the plans and specifications or stop the Owner or Engineer from requiring that all work be fully and properly performed including, if necessary, removal of defective or otherwise unacceptable work and the re -doing of such work. 3. General Obligations and Responsibilities 3.01 Keeping of Plans and Specifications Accessible The Engineer shall furnish the Contractor with an adequate and reasonable number of copies of all plans and specifications without expense to him and the Contractor shall keep one (1) copy of the same constantly accessible on the work, with the latest revisions noted thereon. 3.02 Ownership of Drawings All drawings, specifications and copies thereof furnished by the Engineer shall not be reused on other work, and, with the exception of the signed contract sets, are to be returned to him on request, at the completion of the work.

Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the GC -20 grocmdlb:spttsm work. It is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and material furnished. Where payment is based on the unit price method, the Contractor agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contemplated and contained in the proposal; provided, however, that in case the actual quantity of any major item should become as much as 20% more than, or 20% less than the estimated or contemplated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to revised consideration upon the portion of the work above or below 20% of the estimated quantity. A "Major Item" shall be construed to be any individual bid item incurred in the proposal that has a total cost equal to or greater that five (5) percent of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices. Any revised consideration is to be determined by agreement between the parties, otherwise by the terms of this Agreement, as provided under "Extra Work ". 5.03 Price of Work In consideration of the furnishing of all the necessary labor, equipment and material, and the completion of all work by the Contractor, and on the completion of all work and on the delivery of all material embraced in this Contract in full conformity with the specifications and stipulations herein contained, the Owner agrees to pay the Contractor the prices set forth in the Proposal hereto attached, which has been made a part of this contract.

It is understood, however, that in case the whole work be near to completion and some unexpected and unusual delay occurs due to no fault or neglect on the part of the Contractor, and Owner may - upon written recommendation of the Engineer - pay a reasonable and equitable portion of the retained percentage to the Contractor; or the Contractor at the Owner's option, may be relieved of the obligation to fully complete the work and, thereupon, the Contractor shall receive payment of the balance due him under the contract subject only to the conditions stated under "Final Payment ". 5.05 Use of Completed Portions The Owner shall have the right to take possession of and use any completed or partially completed portions of the work, notwithstanding the time for completing the entire work or such portions may not have expired but such taking possession and use shall not be deemed an acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost of or delays the work, the Contractor shall be entitled to such extra compensation, or extension of time, or both, as the Engineer may determine. The Contractor shall notify the Engineer when, in the Contractor's opinion, the contract is "substantially completed" and when so notifying the Engineer, the Contractor shall furnish to the Engineer in writing a detailed list of unfinished work. The Engineer will review the Contractor's list of unfinished work and will add thereto such items as the Contractor has failed to include. The "substantial completion" of the structure or facility shall not excuse the Contractor from performing all of the work undertaken, whether of a minor or major nature, and thereby completing the structure or facility in accordance with the Contract Documents. 5.06 Final Completion and Acceptance Within ten (10) days after the Contractor has given the Engineer written notice that the work has been completed, or substantially completed, the Engineer and the Owner shall inspect the work and within said time, if the work be found to be completed in accordance with the Contact Documents, the Engineer shall issue to the Owner and the Contractor his Certificate of Completion, and thereupon it shall be the duty of the Owner to issue a Certificate of Acceptance of the work to the Contractor or to advise the Contractor in writing of the reason for non - acceptance. GC -22 1 1 5.07 Final Payment 1 Upon the issuance of the Certificate of Completion, the Engineer shall proceed to make final measurements and prepare final statement for the value of all work performed and materials furnished under the terms of the Agreement and shall certify same to the ' Owner, who shall pay to the Contractor on or before the 30th day, and before the 35th day, after the date of the Certificate of Completion, the balance due the Contractor under the terms of this contract; and said payment shall become due in any event upon said performance by the Contractor. Neither the Certificate of Acceptance nor the final ,payment, nor any provision in the Contract Documents, shall relieve the Contractor of the obligation for fulfillment of any warranty which may be required. ' 5.08 Payments Withheld The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself 1 from loss on account of: a) Defective work not remedied or other obligations hereunder not done. b) Claims filed or reasonable evidence indicating probable filing of claims. 1 c) Failure of the Contractor to make payments properly to subcontractors or for material or labor. 1 d) Damage to the Owner or another contractor's work, material or equipment. e) Reasonable doubt that the work can be completed for the unpaid balance of the 1 contract amount. 0 Reasonable indication that the work will not completed within the contract time. g) Other causes affecting the performance of the contract. t When the above grounds are removed or the Contractor provides a Surety Bond satisfactory to the Owner, which will protect the Owner in the amount withheld, payment shall be made for amounts withheld because of them. 1 5.09 Delayed Payments 1 Should the Owner fail to make payment to the Contractor of the sum named in any partial or final statement, when payment is due, then the Owner shall pay to the Contractor, in addition to the sum shown as due by such statement, interest thereon at the rate of 6% per annum, unless otherwise specified, from date due as provided under 1 ge«adlb:spocam GC -23 1 'partial payments' and final 'payments,' until fully paid, which shall fully liquidate any injury to the Contractor growing out of such delay in payment. It is expressly agreed 1 that delay by the Owner in making payment to the Contractor of the sum named in any partial or final statement shall not constitute a breach of this contract on the part of the Owner nor an abandonment thereof nor shall it to any extent or for any time relieve the 1 Contractor of his obligations to fully and completely perform hereunder. 6. Extra Work and Claims 6.01 Change Orders ' Without invalidating this Agreement, the Owner may, at any time or from time to time, order additions, deletions or revisions to the work; such changes will be authorized by Change Order to be prepared by the Engineer for execution by the Owner and the 1 Contractor. The Change Order shall set forth the basis for any change in contract price, as hereinafter set forth for Extra Work, and any change in contract time which may result from the change. ' In the event the Contractor shall refuse to execute a Change Order which has been prepared by the Engineer and executed by the Owner, The Engineer may in writing 1 instruct the Contractor to proceed with the work as set forth in the Change Order and the Contractor may make claim against the Owner for Extra Work involved therein, as hereinafter provided. 1 6.02 Minor Changes 1 The Engineer may authorize minor changes in the work not inconsistent with the overall intent of the Contract Documents and not involving an increase in Contract Price. If the Contractor believes that any minor change or alteration authorized by the Engineer involves Extra Work and entitles him to an increase in the Contract Price, the Contractor shall make written request to the Engineer for a written Field Order. In such case, the Contractor by copy of his communication to the Engineer or otherwise in writing shall advise the Owner of his request to the Engineer for a written Field Order and that work involved may result in an increase in the Contract Price. Any request by the Contractor for a change in Contract Price shall be made prior to ' beginning the work covered by the proposed change. 6.03 Extra Work 1 It is agreed that the basis of compensation to the Contractor for work either added or gc.cm:ap m GC -24 1 gcocond(b:apecam deleted by a Change Order or for which a claim for Extra Work is made shall be determined by the unit prices upon which this contract was bid to the extent such work can be fairly classified within the various work item descriptions and for work items that cannot be so classified by one or more of the following methods: Method (A) By agreed unit prices; or Method (B) By agreed lump sum; or Method (C) If neither Method (A) nor Method (B) be agreed upon before the Extra Work is commenced, then the Contractor shall be paid the "actual field cost" of the work, plus fifteen (15) percent. In the event said Extra Work be performed and paid for under Method (C), then the provisions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost to the Contractor of all workmen, such as foreman, timekeepers, mechanics and laborers, and materials, supplies, trucks, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, including Social Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of premiums on Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property Damage and Workmen's Compensation, and all other insurance as may be required by any law or ordinance, or directed by the Owner, or by them agreed to. The Engineer may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made available to the Engineer. The Engineer or Owner may also specify in writing, before the work commences, the method of doing the work and the type and kind of machinery and equipment to be used; otherwise these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be determined by using 100 per cent, unless otherwise specified, of the latest schedule of Equipment Ownership Expense adopted by the Associated General Contractors of America. Where practicable the terms and prices for the use of machinery and equipment shall be incorporated in the Written Extra Work Order. The fifteen (15 %) percent of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, general superintendence and field office expense, and all other elements of cost and expense not embraced within the "actual field GC -25 gcncoodfb:speesm cost" as herein defined, save that where the Contractor's Camp or Field Office must be maintained primarily on account of such Extra Work; then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for Extra Work of any kind will be allowed unless ordered in writing by the Engineer. In case any orders or instructions, either oral or written, appear to the Contractor to involve Extra Work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the Engineer for written order authorizing such Extra Work. Should a difference of opinion arise as to what does or does not constitute Extra Work, or as to the payment therefor, and the Engineer insists upon its performance, the Contractor shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as provided under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to arbitration, as hereinbelow provided. 6.04 Time of Filing Claims It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Engineer within thirty (30) days after the Engineer has given any directions, order or instruction to which the Contractor desires to take exception.

In case the Contractor should appeal from the Engineer's decision, any demand for arbitration shall be filed with the Engineer and the Owner in writing within ten (10) days after the date of delivery to Contractor of the Engineer's final decision. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to any claims by either party, except claims by Owner for defective work or enforcement of warranties and except as noted otherwise in the contract documents. 6.05 Continuing Performance The Contractor shall continue performance of the contract during all disputes or disagreements with the Owner. The production or delivery of goods, the furnishing of services and the construction of projects or facilities shall not be delayed, prejudiced or postponed pending resolution of any disputes or disagreements, except as the Owner may otherwise agree in writing. 6.06 Arbitration All questions of dispute under this Agreement shall be submitted to arbitration at the request of either party to the dispute. The parties may agree upon one arbiter, otherwise, there shall be three, one named in writing by each party, and the third chosen by the two arbiters so selected; or if the arbiters fail to select a third within ten (10) days, he shall GC -26 be chosen by a District Judge serving the County in which the major portion of the project is located, unless otherwise specified. Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of the Engineer shall be final and binding on him. Should the other party fail to choose an arbiter within ten (10) days, the Engineer shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take ex parte proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any questions submitted to arbitration under this contract shall be a condition precedent to any right of legal action. The decision of the arbiter or arbiters may be filed in court to carry it into effect. The arbiters, if they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the appeal was taken without reasonable cause, they may award damages for any delay occasioned thereby. The arbiters shall fix their own compensation unless otherwise provided by agreement, and shall assess the cost and charges of the arbitration upon either or both parties.

After receiving said notice of abandonment the Contractor shall not remove from the work any machinery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under contract for the work, may be held for use on the work by the Owner or the Surety on the performance bond, or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefor (except when used in connection with Extra Work, where credit shall be allowed as provided for under Section 6, Extra Work and Claims), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. GC -27 genemd/b:speesm Where there is no performance bond provided or in case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for, within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (1) The Owner may thereupon employ such force of men and use such machinery, equipment, tools, materials and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said Contractor, and expense so charged shall be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said Contractor, then the Contractor and /or his Surety shall pay the amount of such excess to the Owner, or (2) The Owner under competitive bids, taken after notice published as required by law, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case there is any increase in cost to the Owner under the new contract as compared to what would have been the cost under' this contract, such increase shall be charged to the Contractor and the Surety shall be and remain bound therefor. However, should the cost to complete any such contract prove to be less than would have been the cost to complete under this contract, the Contractor and /or his Surety shall be credited therewith. When the work shall have been substantially completed the Contractor and his Surety shall be so notified and Certificates of Completion and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the contract accounts, certified to by the Engineer as being correct, shall then be prepared and delivered to the Contractor and his Surety, whereupon the Contractor and /or his Surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement, within fifteen (15) days after the date of such Certificate of Completion. In the event the statement of accounts shows that the cost to complete the work is less than that which would have been the cost to the Owner had the work been completed by the Contractor under the terms of this contract; or when the Contractor and /or his Surety shall pay the balance shown to be due by them to the owner, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be turned over to the Contractor and /or his Surety. Should the cost to complete the work exceed the GC -28 contract price, and the Contractor and /or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract, provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any machinery, equipment, tools, materials, or supplies, which remain on the work, and belong to persons other than the Contractor or his Surety, to their proper owners. The books on all operations provided herein shall be opened to the Contractor and his Surety. 7.02 Abandonment by Owner In case the Owner shall fail to comply with the terms of this contract, and should fail to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools and equipment, and all materials on the site of work that have not been included in payments to the Contractor and have not been wrought into the work. And thereupon the Engineer shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Contractor (at the prices stated in the attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion and which cannot be utilized. The Engineer shall then make a final statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this Agreement and shall certify same to the Owner who shall pay to the Contractor on or before thirty (30) days after the date of the notification by the Contractor the balance shown by said final statement as due the Contractor, under the terms of this Agreement. 8.

The Contractor will not be required to contract with any Subcontractor or person or organization against whom he has a reasonable objection. If the Owner or Engineer refuses to accept any Subcontractor or person or organization on a list submitted by the Contractor in response to the requirements of the Contract Documents or the Instructions to Bidders, the Contractor shall submit an acceptable substitute and the Contract amount shall be increased or decreased by the difference in cost occasioned by such substitution and an appropriate change order shall be issued; however, no increase in the Contract amount shall be allowed for any such substitution unless the Contractor has acted promptly and responsively in submitting for acceptance any list or lists of names as required by the Contract Documents or the Instructions to Bidders. If the Owner or the Engineer requires a change of any proposed Subcontractor or person or organization previously accepted by them, the Contract amount shall be increased or decreased by the difference in cost occasioned by such change and an appropriate Change Order shall be issued. The Contractor shall not make any substitution for any Subcontractor or person or organization who has been accepted by the Owner and the Engineer, unless the substitution is acceptable to the Owner and the Engineer. 8.02 Subcontractual Relations All work performed for the Contractor by a Subcontractor shall be pursuant to an appropriate written agreement between the Contractor and the Subcontractor (and where appropriate between Subcontractors and Sub - subcontractors) which shall contain provisions that: (1) preserve and protect the rights of the Owner and Engineer under the Contract with respect to the work to be performed under the subcontract GC -30 so that the subcontracting thereof will not prejudice such rights; (2) require that such work be performed in accordance with the requirements of the Contract Documents; (3) require submission to the Contractor of the applications for payment under each subcontract to which the Contractor is a party, in reasonable time to enable the Contractor to apply for payment in accordance with this contract; (4) require that all claims for additional costs, extensions of time, damages for delays or otherwise with respect to subcontracted portions of the work shall be submitted to the Contractor (via any Subcontractor or Sub - subcontractor where appropriate) in sufficient time so that the Contractor may comply in the manner provided in the Contract Documents for like claims by the Contractor upon the Owner; (5) obligate each subcontractor specifically to consent to the provisions of this section.

The Contractor shall also require each Subcontractor to make similar payments to his subcontractors. If the Engineer fails to approve a payment for any cause which is the fault of the Contractor and not the fault of a particular Subcontractor, the Contractor shall pay the Subcontractor on demand, made at any time after the Certificate for Payment should otherwise have been issued, for his work to the extent completed, less the retained percentage. The Engineer may, on request and at his discretion, furnish to any Subcontractor, if practicable, information regarding percentages of completion certified to the Contractor on account of work done by such Subcontractors.

Failure of the Contractor to so inspect and report shall constitute an acceptance of the other contractor's work as fit and proper to receive his Work, except as to defects which may develop in the other separate contractor's work after the execution of the Contractor's Work. Should the Contractor cause damage to the work or property of any separate contractor on the project, the Contractor shall, upon due notice, settle with such other contractor by agreement or arbitration, if he will so settle.

LNTRODUCTION 1.1 PURPOSE This document is intended to provide methods and prac- tical standards for installing ground systems hich will mini- mize the hazards to personnel and equipment caused by lightning surges and ground faults, as w•clI as to minimize in- duced noise and static. 1.2 ASSUMPTIONS It is assumed throughout this document that the soil in which a ground system is to be established is of average resis- tivity and that subsurface formations do not prevent ground. 2. OVERVIEW NOTE Local codes take precedence if they are more conservative. A • grounding system is made up of a num- ber of sub - systems, both interior and exterior. These consist of certain basic components arranged to achieve the goals of the ground system and adapted to the characteristics of indi- vidual sites. Although the exact configurations vary from place to place, the components of which a ground system is constructed generally remain the same, and the general guid- ing principle always do. While the specifics of those princi- ples can fill volumes, and this document is not intended to be a theoretical teaching medium, the basic philosophy of this type of ground system can be summed up quite briefly. 3. GENERAL TECHNIQUES The purpose of grounding was stated in the section 1.1; the general techniques by which those purposes are accom- plished are described below. While these statemctts are somewhat simplified, it can be fairly stated that most' . radio grounding is based on these principles or techniques, adapted where and when necessary to meet special require- ments at particular sites. 2 6SPS1150E62-0 3.1 EXTERNAL GROUND SUB - SYSTEM For sites with radio towers; proside the lowest imped- ance path possible (within practical limits) from the antennas and tower to ground, external to the building. Several sub- systems are used to achieve this goal. The tower ground con- sists of a buried ring of wire encircling the tower base. The external building ground usually takes the form of a buried ring of wire around the building, although other designs may be used. This ring is referred to as the external ground ring (EGR). It provides the primary connection to earth for the re- mainder of the site. These rings are connected together and supplemented with ground rods. Finally, all rf transmission line shields are grounded at the building entry point, using a large copper bar as a tie-point between the EGR and the shield ground leads. 3.2 INTERNAL GROUND SUB- SYSTEM 3.2.1 The internal system must achieve a low impedance path to ground at the ground window, or common junction point of interior grounds, and also achieve a minimal potential difference between conductive structures within the site, while eliminating (or at least minimizing) any surge current flow through the site's equipment. Safety of personnel and equipment is the overriding concern of this document, not sig- nal grounding; the construction of cellular fixed equipment achieves good signal grounding internally, through the inher- ent quality of its design. 3.2.2 Internal ground connections are made to the Master Ground Bar (MGB); a large copper bar used as a low resis- tance junction point for all internal grounds. All rf equipment is tied directly to this main bar, which is itself tied to the exter- nal ground system, the commercial ac ground, and other ground sources such as building steel. Other ground bars, tied back to the main bar, are used to tie clusters of associated equipment together, to isolate them from surges while mini- mizing inter-equipment voltages within that local cluster. Equipment racks, or bays, must be isolated from any "sneak" or unplanned ground paths to avoid surge current flow, usu- ally by placing them on insulating pads. Finally, an elevated wire ring ties miscellaneous conductive items such as door frames to the ground bar. This ring is also tied to the outside ground at several points, which improves the effectiveness of the main, or master ground bar. 33 SURGE PROTECTION To prevent the above efforts from being circumvented by surges entering "by the back door," all conductors that enter the building, whether power or telecommunications types, must be protected by devices such as gas gap or MO V protec- tors. These will bypass and dissipate surges arriving on those lines. There are various types of surge protection devices, and care must be taken to see that the type provided by utilities 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 companies, the customer, or Motorola are of the correct type and rating for the application. 4. DEFINITIONS A summary of the various terms and component parts used in ground systems, with their abbreviations and defini- tions, is given below. 4.1 EXTERNAL GROUND RING (EGR) A buried external bare wire that is usually in the form of a ring around the building, and which, together with the tower ring and their associated ground rods, forms the main ground terminus for the site. It may take the physical form of an "E" shape in cases where there is only access to one side of the building. See also "Ufer Grounds." 4.2 TOWER GROUND RING This is a ring of bare, buried wire surrounding the tower base, connecting the several tower ground rods together, and is connected to the tower by one or more conductors. It must also be connected to the EGR. 43 INTERNAL GROUND RING (IGR) This is a ring of bare wire near the top of the interior walls (sometimes called the "Halo" from its appearance), and serves to connect the miscellaneous non-equipment signifi- cant metal objects to a common ground at the master ground bar. It is grounded to the EGR at several points. 4.4 MASTER GROUND BAR (MGB) Physically, this is a large copper bar with pre - drilled mounting holes for lugs. It serves as a convenient, low resis- tance tie point for ground leads, which are either run directly to the MGB or connected via an isolated ground zone bar. An example of its use is shown in drawing AGB-023 -218 (Ap- pendix C), and specific part- numbered bars suitable for MGB/IGB use are illustrated drawing AGC -023 -234 (Ap- pendix C). 4.5 ISOLATED GROUND ZONE (IGZ) Simply, this is an association of non - surging equipment (that is, equipment not likely to be exposed to lightning surges either through power or signal leads, except as a result of in- correct installation). This equipment is connected to a local, common ground point called the "Isolated Ground Bar," which in tum is connected to the MGB. No other ground con- nection is permitted; to help assure this is so, special isolated ac outlets, color -coded orange, are used for any test equip- GROUNDING GUIDELINE men[ in the IGZ. These outlets have their "green wire" ground tied only to the isolated ground bar in the IGZ. They derive the required connection to the main ac power multi- grounded neutral, or "green wire" ground via connection between the IGZ ground bar (IGB) and the MGB. Care must be taken to avoid violations from uninsulated cable trays, conduits, etc. as well. 4.6 ISOLATED GROUND BAR (IGB) Similar to, but usually smaller than the MGB, it serves as a junction point for an isolated ground zone. It serves to refer- ence IGZ equipment to the same potential, and is always con- nected to the MGB. 4.7 MULTI - GROUNDED NEUTRAL (MGN) The "official" name for the ac power line "green wire" ground. it is grounded at a number of points along the utility transmission path by the power company. By extension, it also is used to designate local generator- sourced ac green, third -wire ground, which is not strictly accurate. The MGN must always be connected to the MGB. 4.8 CADWELD ° PROCESS CADWELD, a registered trademark of Erico Products, Inc., Cleveland, Ohio, is the name of a process for exotherm i- cal welds (ground system components in particular). Instead of gas or are welding apparatus, a unique powdered metal mixture is used in conjunction with special graphite molds. The powder reacts to produce molten copper, which [lows around and slightly melts the items being joined. The result is a permanent, high quality, strong, and low resistance joint. This process is required for all outside ground system connec- tions with the optional exception of the tower ring -to-EGR joint (this is explain in later sections). Examples of various CADWELD products and connections are given in Appen- dix -A and Appendix -C. 68P81150E62-0 3 4.10 GROUND RODS Ground rods shall be copper -clad steel rods of minimum eight foot length, 5/8 in. diameter, except in the case of a deep basement adjacent to the rods; in which case the external ground ring rods will be either 15 ft. long. or extend at least 3 ft. below the cellar floor's depth. Longer and larger diame- ter rods are acceptable; for rods 15 ft. or longer, 3/4 in. diame- ter is recommended. Also permitted are stainless steel rods, if plain steel fuel tanks or other metal items subject to corrosion are buried near the ground installation. 4.11 CONDUCTORS These are the wires or straps which connect ground rods together, form ground rings, and allow connection of objects to be grounded to the ground system. Conductor type and size are determined by impedance. ability to withstand fusing, strength (particularly underground), and resistance qualities. 4.11.1 Conductor Types $FLOW GROUND: Tinned, solid copper wire is re- quired. ABOVE (;ROUND: Either solid or stranded copper wire is permiued. Internal ground ring (IGR) conductors must be bare; equipment ground leads in cable trays must be insulated (green color is desirable for ready identification). Miscellane- ous grounds to door frames, etc. from the IGR may be insu- lated if desired. Exception: Tinned copper wire must be utilized for tower guy wire ground leads to prevent corrosion of galvanized guy wires; see section 6.3 (Tower and Monopole Grounding). 4.11.2 Conductor Sizes ABOVE GROUND: For ground rings and the intercon- nection of internal and external ground rings, #2 AWG or larger, is required. For grounding of equipment and miscella- neous metallic objects, #6 AWG minimum, is acceptable. Exceptions: connection from isolated ground zone ground bar (1GB), or ground window bar (GWB), to master ground bar (MG B), and connection from antenna coax arrestor bar (if not pan of entry window plate) to cable entrance window shall be #2 AWG, minimum. External ground window bar or cable entry window (if that serves as a ground point for the an- tenna transmission lines) shall be grounded through a mini- mum 2 in. wide, 16 gauge copper strap. In the case of unguyed towers, the use of two such straps spaced several inches apart. separated by a plastic jacket, is preferred for the reduction in surge impedance thus provided. Contact Sys- tems Engineering for recommendations if specific circum- 4 681'81150E62-0 stances, such as local codes, require larger conductors. or if these requirements cannot be met. BELOW GROIN'D: All conductors will be #2 AWG, minimum. 4.12 CONNECTIONS 4.12.1 Below Ground All connections should be of CADIVELD exothermic weld construction or equivalent. (Refer to product literature and related drawings in the appendix). Bolted clamps are ac- ceptable only for the connection between the tower and build- ing ground systems, should it be desired (by the customer) to perform separate resting; materials utilized must not corrode, deteriorate, or loosen. The joint must be in a covered test well for access. In no case shall non - welded connections be used for the ground rod to wire ring, tower, and building jumpers. 4.12.2 Above Ground When two or more grounding conductors are to be joined. either exothermic weld (CADIVELD process; or equivalent), split -bolt (copper alloy) or pressure type crimp connectors, are acceptable, except that crimp connections shall not be used on solid conductors. 4.12.3 Connection to Equipment Connection of conductors to equipment should he by the use of lugs or clamps appropriate to the size and type of wire and provisions of the equipment being grounded. 4.12.4 Connection Joint Preparation The surfaces of each conductor to be connected are to be well cleaned, removing all paint, dirt, and corrosion in the area of connection before each joint is made. After mechani- cal joints are completed, application of an anti- oxidant com- pound, such as "NO -OX" or equivalent is recommended. When using non - welded mechanical connections. such as bolt -on lugs, the use of star washers or similar devices appro- priate to the fastener is required. These steps will help ensure a continued good electrical and mechanical connection. 5. GENERAL PRACTICES 5.1 INTERCONNECTION OF INTERNAL/EXTERNAL GROUNDS This will be accomplished so as to form an integrated "ring" encircling both the building's interior equipment arca and, whenever possible, the building's exterior perimeter ground (EGR). This interconnection will be at the internal MGB and at each corner, and shall be run through non -con - ductive conduit. See also paragraph 6.2.1.3. 5.2 SHARP BENDS IN CONDUCTORS These are to be avoided, as they add inductance and are also prone to damage from lightning derived magnetic flux. A bending radius of 8 in. or more is recommended. 6. EXTERNAL GROUNDING SYSTEM 6.1 GENERAL 6.1.1 The following information concerns the low imped- ance connection to earth for the equipment site. In general, ground system resistances of less than 10 ohms must be achieved, with 5 ohms or less being the goal. 6.1.2 The external ground is made up of the EGR, the tower ground ring (if there is any rf equipmen t at the site), and their associated ground rods, plus available Ufer grounds. To these are added safety grounds to fences, external generators, guy wires, etc. all of which contribute to the effectiveness of the overall system. Finally transmission line grounding is de- signed to divert the majority of current to earth prior to its en- try to the site, by grounding the transmission line shield to the tower at its top and at the point at which it exits the tower, and then at the rf cable entry window, using a wide strap for a low impedance, "last chance" ground path. (The appendixes of this section contain detailed, illustrated ground testing proce- dures.) 6.1.3 The following list is a summary of the drawings found in Appendix C that are applicable to the external .a4 wv1• uvivcutIC ground system (including towers), as well as its interconnec- tion with the internal ground system: • AGC -023 -215, External Ground Window Detail • _ • AGB -023 -219, Typical Cell Site Ground Plan • AGB -023 -220, Tower Base and Guy Wire Ground- ing Details • AGC -023 -221, Example of Ufer Ground Plan. Appendix A and Appendix C contain related information and illustrations. WARNLNG Consult with the local utility (electric, gas, tele- phone, and water) companies to determine the location of any underground facilities prior to digging. The point of contact can be the utility locator service. Failure to do so can result in ex- pensive damage to those systems, as well as injury or death to personnel. 6.2 BUILDINGS 6.2.1 The External Ground System 6.2.1.1 The building external ground system should con- sist of a ground rod beneath the cable entry ground window, placed outside of the roof "drip" line (offset a few inches to allow room for connection of a ground strap to window). To this are to be added interconnected rods at each corner of the building and additional rods as necessary, to reduce the dis- tance between rods to 15 feet. lf, for example, a building side is longer than 16 feel but shorter than 30 feet, one rod must be placed near the center. The rods should be driven, using the proper tool to prevent rod deformation and thread damage to threaded coupling rods, if used. ( a recommends the use of non - threaded rods joined by CADIi ELD "GB" con- nections.) Ground rods are not to be placed in drilled holes, unless specifically approved by ' • Systems Engi- neering. The rods are to be sunk until the rod tops are at a minimum depth of 18 inches below finished grade. The ma- jority (more than 2/3) of the rod's length must be below the local frost line. The rods should be placed in a line approxi- mately two feet from, and parallel to, the building foundation. 6.2,1.2 Rods will be connected in a ring (the external ground ring, or EGR) using bare, tinned, t2 AN'G wire, bur- 68P8II50E62-0 5 ied to the same depth as the tops of the ground rods. This wire interconnecting ring must be exothermically welded to each of the rods. 6.2.1.3 Each extemal ground ring connect- ing jumper must be run through non - metallic pipe or conduit through the floor or wall of sufficient size to pass a #2 AWG wire. Metallic conduit can cause flashover and will also de- crease the effectiveness of the grounding system. These en- trances should be provided adjacent to each ground rod. 6.2.2 Inaccessible Building Sides 6.2.2.1 If all sides of a building are not accessible, con - structing a straight or "L" shaped ground bus on each accessi- ble side, supplemented by Ufer grounding (a conductor encased in concrete, such as foundation reinforcing bar), the building steel, etc., will be acceptable. 6.3 TOWER AND MONOPOLE GROUNDING 63.1 Lattice Tow 63.1.1 Lattice Towers should be grounded with at least one ground rod adjacent to each tower leg; rods are to be con- nected to the tower leg with #2 AWG copper wire, and to one another with a ring of bare, tinned, solid #2 AWG wire. The vertical, ground ring - to - tower wire should be insulated from earth contact for the first 12 inches or more by passing it through a PVC pipe. This is to reduce the step voltage in the immediate vicinity of the tower. CAD1i'£LD or equivalent exothermic weld joints are to be used, as specified in section 4.12.1. Again, if the distance between ground rods is more than 15 feet, additional rods will be used to reduce the dis- tance between rods to 15 feet (e.g., if the rods are 20 feet apart, a rod is driven midway between the two tower leg rods). A connection from the tower ground will be made to the build- ing external ground system. 6 68PS 1150E62-0 63.1.2 It is recommended that the base ground ring of unguyed towers be supplemented by at least two radial wines. These should be approximately 20 feet, or as long as is practi- cal at the particular site, and extend away from the building. Refer to section 6.4.2 and drawings AG B-023-219. and AGB -023 -220 (Appendix C) for more information. 63.2 Monopole Masts These antenna supports typically exhibit much greater current surges when struck by lightning, as compared to guyed towers which have additional paths to ground. They must therefore be grounded with a minimum of four ground rods, connected together as specified in paragraph 6.3.1.2 above, and as shown in drawing AGB -023 -217 (Appendix C). Where feasible, the addition of one or two short radials (20 feet is adequate) extended outward from the monopole base and away from the site building, is recommended. This will serve to reduce the share of current on the rf transmission lines by lowering the base impedance of the tower. These optional ground radials should have a ground rod at the middle and at the end, and will otherwise follow the construction guidelines for external buried conductors. Any large metal objects such as fences encountered along their path will be jumpered to the radial, to reduce shock hazards. 6.3.3 Cu) ed Towers Guy wires added to an antenna tower not only adds sta- bility to the tower installation, but can also reduce the current share of the tower (and thus the surge voltage Icvcl of the MGB), since the tower guys become part of the overall ground circuit of the antenna installation. Another benefit of guyed towers is the wider area over which current can be dis- persed, allowing more rapid dissipation and reduced step voltage. It is very important, however, that the guys be well grounded. 6.3.3.1 GUY WIRE GROUNDING Each guy wire will be grounded at the anchor point. A ground rod will be installed at each guy anchor and wire con- GROUNDING GUIDELINE net as in paragraph 6.3.1.1. Further, the connection to the guy wires must be made with bronze, stainless steel, or galva- nized steel clamps to avoid corrosion of the guys. The ground- ing wire must be tinned copper #2 AWG, and care must be exercised at the time of installation to maintain the integrity of the tin coating. Under no circumstance is bare copper wire permitted to be in contact with galvanized steel, as a serious corrosion potential will exist. This wire will pass through an insulating pipe such as PVC, or similar, extending from sev- eral inches above ground to at least 12 inches below ground. This will greatly reduce the step voltage hazard. Finally, this wire will be exothermically welded (CADIVELD process) to the guy wire ground rod. After tightening, the clamps should be well protected by an anti- oxidant compound such as' No- Ox," or its equivalent, as bare or taped joints will soon dete- riorate. 6.3.3.2 MAINTENANCE AND LN SPECTIONS A ground system, by its very nature, is exposed to weath- ering and corrosion. This, coupled with the importance of the ground system to the safety of personnel and equipment makes it mandatory that periodic inspections be made of all ground system components. A suggested schedule is immedi- ately after a ground installation has been installed or modi- fied, three to six months afterward, and then annually. The security of all bolted or clamped connections and the condi- tion of the wire jumpers exposed to physical damage are two key checks to be made. 6.4 MISCELLANEOUS GROUND CONNECTIONS Objects which should be connected to the external ground network include, but are not limited to, the following: 1. Any metal fence within seven feet of the external ground network or any other grounded object. 2. The transmission line entrance hatch (if metallic). Minimum conductor size #2 AWG, but 2 in. or wider strap preferred if coax shields are grounded there in- stead of on external ground bar. 3. Metal building paris nototherwise grounded by the in- te ground ring, such as downspouts, siding, secu- rity grates over windows, metal ground mats, etc. 4. Fuel storage tanks, whether above or below ground. NOTE If fuel storage tanks are steel (not stainless) and unprotected by an anti- corrosion coating, care must be taken to avoid a galvanic corro- sion source. Wire of same metal, or stainless hardware should be used. 5. A ground rod or rods provided by the power or tele- phone utility for grounding of ac ground or protectors, if permitted by local codes. NOTE The utility ground should be connected to site MOB or G WB. If utility ground bar is internal to building, that point should be used instead and be wired to the site's MGB directly. 6. Any significant metal object (more than 2 sq. ft. in area) within seven feet of the external ground system or any other grounded object. 7. Reinforcing bar in concrete floors, if accessible. (This is actually a type of "Lifer" ground —a very effective supplemental ground). For sites on concrete slabs in contact with earth, the considerable ground system improvement which may be realized by including this ground will nearly always justify the effort required. However, because of the very high current density at the tower base, placing ground rods in tower founda- tions is not advised, to avoid possible heating effect damage to the concrete. 8. Building skids or pier foundation anchors of pre -fab- ricated buildings. 9. Exterior cable tray and ice shields, which are to be grounded at the tower /monopole end also. 10. An external ground bar should be installed just be- neath the entry point of the coax transmission lines, as a termination for coax shield grounding kits, if the en- try window is not a suitable type for grounding. This bar will be connected to the external ground ring with minimum 2 in., 16 gauge copper strap, and to the in- side ground via a #2 AWG insulated wire to the entry window. The internal coax arrestor bar will also be connected to this point and thus to the external bar via a common bolt This bar and its connections may be seen in drawing AGC -023 -215 (Appendix C). 68P81150E62-O 7 7. THE LNTERNAL GROUND SYSTEM The internal ground system will consist of two major ele- ments; the internal ground ring (1GR) and the single point ground system, which will include an isolated ground zone (IGZ) in the area on collocated sites. 7.1 THE INTERNAL GROUND RING 7.1.1 General 7.1.1.1 The IGR (sometimes called the ground halo) al- lows short lengths of wire from individual non - equipment metal objects (door frames, air ducts, etc.) to be connected to the internal ground system for safety purposes. 7.1.1.2 The IGR is tobe connected to the internal main, or "master" ground bar (MGB) as well as to the external ground at several points. This practice improves the effectiveness of the MG B's grounding by reducing it's inductance to the EGR and therefore to "true ground." Refer to drawing AG B-023-219 in Appendix C. 7.1.2 IGR Location and Mounting The IGR should be the lower of a level about six inches from the ceiling or 8 -10 feet above the floor. The internal ground ring should be be mounted on stand -offs or be sus- 8 If this style of bar, with Its wide ground strap is not used, an acceptable alternative would be two or even three #2 AWG wires, exothermically welded to the bar at least six inches apart. They must maintain that distance as they run down to the EGR, to reduce mu- tual inductance, and they must be insulated from the wall. There is one other variation that is occasionally encountered, which is a very effective (but costly) combination of an entry window, a very wide ground strap, and an arrestor bar. It is described on page 32 of The "Grounds" for Lightning and EMP Protection (see Appendix B). It is slightly more effective than the two methods described above, but at a considerably greater cost. Although not very cost effective, it is an acceptable implementation, when a customer desires to employ it. 11. Outside ac generator plants require their own ground rod, and a jumper to the associated concrete slab's steel mesh or reinforcement bar. This ground will con- nect to the EGR with the standard #2 All'G, bare, tinned wire. Inside emergency generators will be con- nected to the main ac MGN as part of their normal in- stallation. If not, its ground point should be connected to the MOB. 68P81150E62 pcnded to permit easy connections. One such method is to use the T B "Ty -Rap" SO -405A standoff with TC -15 cable tie, or equivalent, attached to the building wall. Other mountings may be acceptable, but should be reviewed by an Implementa- tion Engineer before installation. 7.1.3 IGR Visibility The ring will not be concealed, to facilitate inspection. 7.1.4 IGR Path At collocated sites, theIGR should encir- cle the radio equipment - - areas, but is not to be con- nected directly to radio or switch equipment, except via the MGB; these equipments will be grounded directly to the MGB or to the isolated ground bar (IGB) by single point grounding. 7.1.5 Connections to the IGR 1. Ventilation louvers or sheet metal ductwork. 2. The cable tray system (at multiple points best). 3. Metal door and window frames. 4. Metal battery racks. 5. Halon fire suppression system. 6. Any other permanent, significant, metal object within seven feet of any other grounded object. 7.2 THE SINGLE POINT GROUND SYSTEM The single point ground system consists of a number of direct connections between each piece of equipment and a ground bar, which is in turn connected to the external ground system, as well as a number of supplemental grounds. At col- located sites, there is a special part of the single point ground installation called the isolated ground zone (IGZ), in which a separate ground bar is connected to a group of closely related equipment (such as the EMX switch and its ancillary racks). This bar, which is known as the isolated ground bar (IGB), is then connected to the site's MGB. It shall be referred to here as the IGB. The connections between equipment and ground bar will be made with green insulated 146 AWG wire (minimum), while the connections between bars will be made with green insulated #2 AWG or larger. De- tails of wiring are given below. 7.2.1 The Master/Main Ground Bar The master (or main) ground bar (MGB) is the site's main ground bar. Physically, it will usually be a heavy, rec- tangular, copper bar that has been drilled to accept a number of connecting lugs and perhaps welded straps or cables. It forms the central, key ground node or junction point of the grounding system, and should have a lower impedance to "true ground" than any other ground point within the build- ing. The bar should be insulated from its support. Its connec- tions are arranged in three main groups; surge producers, surge absorbers and non - surging objects. The wires from the surge-absorbing objects should be connected in the central area of the bar. Examples of appropriate types are shown in drawing AGC -023 -234 (Appendix C), while typical MGB connections are shown in AGB -023 -218 (Appendix C). 7.2.2 Connections to the MGB Surge Absorbers 1. External ground ring, using a #2 AWG wire (mini- mum); but a 2 in. copper strap is preferred; either lead must pass through an insulating channel to the EGR, by the most direct route. Sharp bends are not permit- ted. 2. Metal water utility pipes on the street side of the meter (when permitted by local codes). NOTE Do Not use gas pipes for grounding. 3. The ac utility ground bar/ground entry bar (also known as the multi - grounded neutral, or "green wire ") if commercial power is available. (The ac entry panel should be close to the MOB). 4. The main ac power panel enclosure (i f local codes per- mit). 5. The telephone terminal block enclosure (as permitted by local codes). 6. Building steel (i.e., girders and/or reinforcement bar). 7.2.3 Connections to the MGB — Nonsurging Objects NOTE While any of the items described below could produce a surge through an unusual circum- stance such as a wiring error, they would not normally do so. It is assumed, as stated in sec- tion 5 (General Practices), that equipment racks/suites/fratnes are insulated at the base and from any contact with condu it, bracing, or any other such foreign ground. 68P61150E62-0 GROUNDING GUIDELINE 1. The IGR, or "halo "; this will terminate at each end of the MGB, a CADWELD process or equivalent connec- tion being preferred, but a cuprous lug exothermically welded to the IGR and bolted to the bar is acceptable. 2. The IGB (isolated ground bar), if an isolated ground zone is present (as it will be in collocated cellAITSO sites), will be connected to the MGB with a minimum #2 AWG green insulated wire. EMX- associated equipment in the IGZ and the "green wire" ground leads from the IGZ orange outlets will be connected to ground only through this bar. ' 7.2.4 Connections to the MGB— Surging Objects 7.2.4.1 The following are, or can be, common sources of surge energy, whether from a local lightning strike or one more distant, and coupled via power or Telco lines. As protec- tors can discharge significant currents into their associated ground leads, the resultant voltage drop and current/magnetic flux can cause damage and induce data corruption in nearby parallel wires. For these reasons, it is critically important to locate the ac and telephone entrance panels as close as possi- ble to the MGB. 7.2.4.2 Drawings illustrating a sample ground systems are AGB-023 -219, Typical Cell Site Grounding, and AGC -023 -216, Example of Typical Collocated Cell/MTSO Site Ground Plan, located in Appendix C. 1. Radioracks/ suites. Connection is to be made at the top of the receiver bay and the transmitter bay for each suite of cellular equipment, nearthecoax connector. A #6 AWG minimum copper wire is recommended for this purpose. It is assumed that all equipment frames within a "suite" are electrically connected together with a heavy copper strap at the base (heavy braid is acceptable, except in tropical or seaside areas). 2. The transmission line entrance hatch (if metallic). A #6 AWG copper wire or larger is recommended. Through this point, connection is made to the trans- mission line external ground bar and the insulated ar- restor bar. These points also connect via the external ground ring connection; this serves as a safety back- up should one of the outside ground leads be broken. 3. Receiver multicoupler.This should be located near the MGB, and a #2 AWG or larger cable is recommended. 4. Telephone protector ground terminal bus. 5. Negative lead of the 24 volt power plant (cellular radio and microwave/multiplex equipment ifpowered by24 V dc). 6. AC Power Line protector ground. 9 1 0 7. Emergency generator. NOTE A separate internal ground system in genera- tor room may be used, but it must be con- nected to the site'sground system, ateither the external ring or the MGB, to equalize poten- tials. 8. Transfer switch enclosure (see note following 7 above). 8. TRANSMISSION LINES • 8.1 WHERE TO GROUND The outer conductor of each transmission line shall be grounded as follows: 1. At the top of the vertical run on the tower. 2. At the bottom of the vertical run on the io ver. 3. At the point of entrance to the radio equipment build- ing (this should be on the external ground bar or imme- diately inside the cable entrance window plate if it is metal; the transmission line grounds may be con- nected to the hatch. 8.2 HOW TO GROUND ' 8.2.1 Grounding of transmission lines is to be accom- plished by use of an appropriate grounding kit supplied by the transmission line manufacturer. 8.2.2 Examples of such kits include the Andrew Corpora- tion's models 204989 -2 and 204989 -4, for 7/8 in. and 1 -5/8 in. lines respectively. The instructions supplied with these kits are to be followed for their correct use. Refer to Andrew Catalog 1133 (available from Andrew Corporation, Orland Park, IL) and drawing AGC -023 -215 (Appendix C). 8.2.3 On monopole antennas, transmission line grounding arrangements must be specified when the monopole is pur- chased, to be sure top and bottom grounding connection points are provided. 681'81150E62-0 8.2.4 Transmission line lightning arrestors must he mounted to an insulated arrestor bar, or to the transmission line entry window if it is of a suitably heavy type ground con- ductor. A short (<3 ft.), single N2 AWG insulated ground wire from the lightning arrestor mounting bar to the transmission line entrance hatch (if metallic) is acceptable, This wire will be bolted to its grounding point on the same bolt uscd to ground the window to the external ground bar, as seen in De- tail A of drawing AGC - 023 - 215 (Appendix C). - 8.2.5 A very significant reduction in surge potential will be realized as the departure point of the transmission lines from the tower is lowered; whenever site circumstances per- mit, the lines should be run to within seven feet of ground or less before leaving the tower, to keep the shield potential (and related current) as low as possible. 9. SUMMARY OF SPECIAL GROUNDING CONSIDERATIONS FOR SITES • The location uses an isolated, single point ground window approach. This means all grounds are tied together at a single point, the isolated ground bar, which becomes a "window" to the actual ground. Physically, the IGB is a cop- per bar with holes for connecting conductors, and is mounted on insulating standoffs. Typical dimensions are 4 inches by 20 inches. Conductors to the ground window/IGB shall be green, insulated, minimum 46 AWG stranded copper wire. Drawing AGC -023 -216 (Appendix C) illustrates a typical collocated site. 9.1 SITES WITH RADIO EQUIPMENT The following is a partial list of items which should be connected to the 1GB (wire gauges are minimums): I. N2 AWG conductor from the external ground system via the site's MGB. 2. fl6 AWG conductor from lug at the top of the EMX common equipment bay cabinet (it is assumed the EMX frames are electrically connected together); 3. The "green wire" ground lead of each isolated, or- ange -coded ac outlet (all ac outlets in EMX area must be of this type, with their grounds tied to IGB). Note that these outlets will have a code- required connec- tion to main ac ground traced through the IGB, that is connected to the MGB, which is, in turn, connected to ac MGN. 4. The isolated ground zone's cable tray system, which must be insulated from non -IGZ trays, and shall not tr 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 be connected to any other ground source, such as con- duit). 5. In special cases, certain channel banks, with no out- side metallic lines may be connected to the IGB, but this should be reviewed by CID Systems Engineering. Normally, channel banks are grounded to the MGB, and are not part of the 1GZ at all. 6. IGZ Distribution Frame (no outside metallic lines or protector grounds permitted; these are lobe connected to the MGB). 8. Modem frames (if not connected to EMX frames). 9. Other EMX- associated, non - surging equipment frames. NOTE The as MGN (green wire) will connect to the IGB only via the site's MGB; all ac outlets in the IGZ mustbe orange-coded , isolated types. , If test equipment or terminals are connected to. the EMX while plugged into a normal outlet in the presence of line surges, the switch will be damaged. 9.2 SITES WITHOUT RADIO EQUIPMENT The following is a partial list of items which should be connected to the IGB: I. #2 AWG conductor from extemal ground system via the MGB, or what serves for one in a non -radio site. This could be a building floor ground bar, for example. 2. #6 AWG conductor from the lug at the top of the Elva common equipment bay cabinet (it is assumed the EMX frames are electrically connected together). 3. #6 AWG conductor from the positive lead of the 48 volt rectifier. 4. Certain channel banks (refer to point 5 in section 9.1); these should usually be grounded the the MGB. 5. Modem frames. 6 Other miscellaneous EMX - associated equipment . frames. 7. Emergency generator ground, via the MG B or equiva- lent. GROUNDING GUIDELINE 8. Main ac power ground bar/MGN ( "green wire" ground) via MGB or floor ground bar. 9. Other miscellaneous large metal objects in switch room. 10. Cable trays (but they must be insulated from non -IGZ trays and must not be connected to any other grounds, such as through conduits. . 11. Orange coded, isolated ac outlets shall be provided for TTY sets and test equipment. The outlet ground shall be tied to the IGB which is itself connected to the site ac MGN "green wire" ground. This provides a code - required path to outside earth ground, while still pro- viding equalized IGZ equipment potentials. 93 FOREIGN GROUNDS 93.1 Foreign grounds must never contact the EMX frames (i.e., those not connected directly to the IG B). 9.3.2 As an aid to avoiding IGZ violations, the IGZ shall' be demarcated by a painted or taped stripe in red or yellow, and labeled as such. 10. GROUNDING PROVISIONS FOR EXISTING BUILDLNGS 10.1 GENERAL 10.1.1 Existing buildings can present a particularly diffi- cult grounding situation. Usually the most difficult grounding problem is to find a usable ground. Every effort should be made to determine what grounding provisions already exist in the building. 10.1.2 Particularly important is finding the "building ground" if it exists. Other alternatives are metallic wa ter pipes (if they can be verified as completely metal runs) which are always accessible with some effort (the building's mainte- nance department will know where), and the building's struc- tural steel, whether girders, elevator shaft vertical support beams or reinforcement rods. These can be effective when used to supplement one another. 10.13 While none of these will provide a very low imped- ancepath to earth if the site is several stories up, the important goal is to keep everything within the site at nearly the same (albeit high) potential. 10.1.4 The foregoing assumes an older, reinforced concrete or brick building; in the case of a smaller, one story structure, in which the site rests upon a concrete slab in contact with the earth, a combination of an external ground, and a "Ufer" ground (obtained by cutting into the slab to find the reinforc- ing bar) may be the solution. 68P81150E62-O 11 10.1.5 As in a "normal" site, all of the grounds just men- tioned will be tied to the \IGB, and further 'Airing will be as outlined above; other than the exact nature of the grounds tied to the MGB, there is no significant difference in internal site grounding. 10.1.6 Finally, common sense plus a bit of creativity, guided by the underlying principles of the foregoing material should help to resolve most grounding problems —or at least to allow initial planning to take place. 10.2 ROOF MOUNTED ANTENNAS TOWERS: 10.2.1 Antennas mounted on the roof of an existing build- ing pose particular problems. Clearly, if the roof is opened to provide reinforcement or direct connection to the steel struc- ture, the opportunity fora good ground is present, and ground leads are to be attached at that time. Other possibilities in- clude elevator shaft steel support girders (must be electrically continuous to building ground in basement) and a pre exist- ing lightning protection system. 10.2.2 The antenna supporting structure should be grounded by a minimum #2 AR`G conductor to the building ground if possible. If multiple grounds or connection points are available, a ground ring around the base of the tower or group of antennas and transmission lines should be formed, much as at a ground level site. Connections, analogous to ground rods at a normal site, will be made from this ring to whatever good grounds are to be found. I03 TRANSMISSION LINE ENTRANCE TO BUILDING The provisions of section 8 (Transmission Lines) should be followed as nearly as possible. Every effort should be made to provide a good ground for the transmission lines at their point of entry to the building. A ground bar, placed just below the entry point, is to be tied to the ground points avail- able using 2 in. strap (or two #2 AWG). The standard Andrews ground kits for the transmission line shields will then be connected to the bar in the usual manner. 12 6S PSI 150E62-0 11. GROUND RESISTANCE MEASUREMENT 11.1 The maximum ac resistance, between any point on the ground system and a reference ground, should be five ohms or less. Exceptions may be permitted in unusual circum- stances, with a slightly higher resistance being allowed in the case of very rocky sites. Such sites and circumstances shall al- ways require review and evaluation by A s c Sys- tems Engineering; safety and certain warranty related issues being involved. An instrument designed specifically for this type of measurement, such as the Biddle Instruments' Meg - gern Earth Testers, must be used, and the instructions pro- vided with the instrument should be followed for proper measurement method. 11.2 The "fall of potential" method is recommended for small sites with an overall ground system diameter of less than 100 feet A Megger Earth Tester, or equivalent, is recom- mended for this tesL Note that an accurate measurement re- quires a distant probe placed at a distance of at least five times the diameter of thesites overall ground system; for large sites, this may not be not practical. Should this situation be encoun- tered, an alternative method may be used. Briefly, this con- sists of taking a series of closer -in readings which give false results, but which trend toward more accurate ones. By then using a graph of these results, and extrapolating the trend , one may closely estimate true ground values. Refer to App:ndix A for a detailed, step -by -step procedure. 12. LIGHTNING PROTECTION MEASURES In addition to the measures described under the preced- ing sections, the following special considerations should be made to minimize the damage from lightning strikes and other unusual electrical disturbances. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 12.1 TRANSMISSION LINES 1. Any unused transmission line should have its center con- ductor shorted to the outer conductor, or a lightning ar- restor installed. 12.2 TELEPHONE LINES 1. Each telephone line (pair) entering or leaving a site should tie equipped with a three-electrode gas tube pro- tector such as the Cook Electric 9A or equivalent. Other types of protectors are acceptable as long as they provide line-to -line and line- to-ground (3 electrode) protection, and have operating characteristics equal to or beuer than gas tube protectors. 2. If possible, negotiate with the local telephone utility to provide the type of protectors described in "1" above. Normally, telephone companies will provide carbon pro- tectors which do not meet the above requirements. 123 AC POWER LINES Recommended are the Joslyn protectors, available for 1 phase and 3 phase applications, part num- bers CGDS126585 and CGDS145501, respectively. Other equivalent ac surge protectors, when correctly sized for the application and potential energy levels, are NOTE If the ac power ground is not connected to the internal ground ring or window (this practice is very undesirable, and proscribed by this specification unless required by a local code), protectors should be used on both sides of this discontinuous ground from each "hot" con- ductor to each ground. 2. 3. also acceptable.. unvurr virtu uUIVtLIN The protector must connect to and protect each un- grounded service conductor. These protectors may be connected on the load side of the main disconnect or on a branch circuit (recommended). If connzction to a branch circuit is used, the branch circuit over current protection device (fuse or circuit breaker) must be sized large enough so it will not open the circuit under normal opera- tion of the ac protector. If an installation as described above is not practical, the ac protector may be installed al the power supply for the radio equipment. Protectors should be used on the line between the channel banks and the microwave, if not optic fiber. 681S1150E62 -O 13 14 68P81150E62-0 GROUNDING GUIDELINE 1. ].1 • • • • • • Step 1. Step 2. APPENDIX A — Ground Testing Methods For "FALL OF POTENTIAL" METHOD EQUIPMENT AND MATERIALS REQUIRED Megger Null Balance Earth Tester (Biddle Instru- ments, Blue Bell, PA). Extra test lead wire (2 spools; 500 ft., # 12 AWG or #14 AWG insulated wire). Test stakes (included with Megger Earth Tester). Long tape measure (100 ft. or more). Compass (to ensure a straight path along which the P2 probe of the Megger Earth Tester will be placed). Two small (1/2 in. diameter) metal hose clamps, or similar device, to fasten extension lead to C2 and P2 probes. 1.2 PROCEDURE NOTE Drawing AGC -023 -214 (Appendix C) illus- trates the following procedure, with a sample graph of the results expected. For a variation of the method described in this procedure, for use on larger sites where a very large ground system or obstructions make obtaining the requisite Cl to C2 distance impractical, please read the section 2 of this Appendix. Jumper the C1 and PI terminals of the Megger Earth Tester together. Connect the short test Icad from terminal CI on the Megger Earth Tester to the approximate elec- trical center of ground system under test (GUT). 68P81150E62-0 Radio Sites NOTE The electrical center of the ground system will probably be the vertical Lead to site's external ground bar, where the rf transmission line shields will be grounded just prior to entering building. This is also near the point where the tower ground ring is jumpered to the build- ing's external ground ring. Other siteconfigu- rations will require local evaluation. Step 3. Connect a long test lead, extended by a length (see following note) of #12 AWG or #14 A \ \'G insu- lated wire, to the C2 terminal of the Megger Earth Tester. NOTE The C2 probe will be driven 1.5 to 2 feet into the ground at a point that is at least 5 times the diameter of the site's ground system (includ- ing the tower ground and grounded fences, guy wire anchors, etc.) from the site. Choose a convenient direction that has no obstacles to the wire or to the insertion of the P2 and C2 probes. Step 4. Firmly clamp the opposite end of the test lead (connected to terminal C2) to the side, and near the top, of the "C2" probe. (Leave enough clearance between the top of the probe and the test lead con- nection to avoid hammer contact and damage to the clamp.) Step 5. With the tape measure, mark a number of points along a straight line (use compass as aid) corre- sponding to the following percentages of the over- 15 Step 6. At each indicated P2 distance (determined in Step 5), insert the P2 probe, its lead extended by a fixed amount of wire as required. (NOTE: don't change length of wire during test). Record amount and size used so its resistance can be subtracted. Step 7. Using the Megger Earth Tester, measure and re- cord apparent ground system resistance at each of the 8 test points. NOTE • As mentioned in the Afegger Earth Tesler manual, a slightly slower or faster cranking speed of the generator will be required if the meter exhibits instability at a particular speed. This is due to stray, interfering 60 Hz power currents in the ground. Resistances should be measured only to nearest tenth ohm. This pre- caution does not apply to battery operated ver- sions. Step 8. 16 all C1 to C2 distance (600 ft. is used in this example): Point 90 Feet (to P2) Ohms 1 20 120 2 30 180 3 40 240 4 50 300 5 55 330 6 62 372 7 70 420 8 80 480 P1 length of wire added C2 length of wire added Plot the accumulated data on linear graph paper. The 62% point will show the true resistance of the ground system when the resistance of the extra wire is subtracted (approximately 1/2 to 1 ohm, de- pending on exact wire type). 681'81150E62-0 NOTE If the data point for the 62% measurement is off the general line of the curve, it may have been corrupted by buried pipes, etc. or in an accurate measurements. The curve as plowed will show a good estimate of the true ground system resistance in that case. 2. THE "ASYMPTOTE VARIATION" OF THE FALL OF POTENTIAL METHOD 2.1 INTRODUCTION Ground tests of cellular infrastructure sites may at times seem to indicate a poor or insufficient ground. While it is cer- tainly possible that the ground plan was inadequate for a par- ticular site, it is important to be aware of the possibility of measurement errors that can result from the choice of an in- correct ground testing method, as opposed to those resulting from mistakes made in the actual reading of the meter itself. A fairly common error is caused by the "Fall of Potential" method described in section 1 of this Appendix, when the C1 to C2 distance is too small as compared to the site's overall ground system dimensions. 2.2 BACKGROUND If the site's ground system is of large size, the required CI to C2 distance of five times the ground system's overall diameter can become impractically large, particularly when it is recalled that this is a minimum distance for reasonable ac- curacy, with a distance of up to twice that value being prefer- able. In such a case, a variation of the above method, used by NASA and other government departments, can obtain very accurate results at much shorter (and more practical) dis- tances. This technique obtains several incorrect ground resis- tance readings, obtained from a set of three normal "fall of po- tential" tests done as usual, except for the use of C2 positions which are too close to the site according to the "times 5 to 10 the site size" rule. These positions vary from very close to merely "somewhat" close. The resultant false ground values (they will all be erroneously high) are then plotted on the same graph paper (or computer display, etc.), and a best -fit, falling exponential curve, connecting each series' 62% reading, is extrapolated out to its asymptote, or nearly flat value. This very closely approximates the true ground resistance. The principle involved is, simply put, that these false readings will tend toward an accurate value as the CI to C2 distance increases, even though the proper distance is never achieved. The point at which the curve becomes flat (or nearly GROUNDING GUIDELINE so) is a close approximation of that true value. An actual ex- ample of the results of both methods, performed on the same site and superimposed on the same graph is shown in drawing AGB -023 -233 (Appendix C); it will be seen that the two re- sults closely agree. The method is explained in further detail in the following step -by -step procedure. 23 EQUIPMENT AND MATERIALS REQUIRED Equipment and material requirements are identical to those in section 1.1 above. 2.4 DETAILED STEPS FOR USING THE "ASYMPTOTE VARIATION" Step 1. Step 2. Step 3. Choose three C2 points at convenient (but non- trivial) distances, such as 100, 200, and 300 feet from the site center. Choose a direction that is free of obstructions, un- derground pipes, etc. All measurements must lie along the same line. Select one of the C1 to C2 distances determined in Step 1 and take a series of readings with the P2 probe, at eight measured intervals representing 30, 40, 50, 55, 62, 65, 70, and 80 percent of each C2 distance. The procedure used for each series of measurements at a given C2 distance is the same as in section I. Again, all of these measurement points (both within a series, and each C2 point) must be in a straight line. Record the data. Step 4. Move the C2 rod to the next point ,as dcterminedin Step 1, and repeat the test of Step 3. Record the data. Repeat for each of the remaining points. NOTE Should additional u ire be needed for the fur- thest measurement (as is likely), it must be in- sulated # 14 AWG or heavier, and a clean, sol- idly clamped and taped connection to the in- strument's C2/P2 test leads be made. Step 5. Step 6. Step 7. The length and gauge of any extension wire should be recorded. The resistance of these wires can later be calculated and subtracted from the results. A long tape measure is required, as actual surface distances are important for graph accuracy. Plot the accumulated data (three curves) in the manner explained above, and then plot the (curve - fitted) 62% points (the "false ground values ") from each series in an exponential curve, the "as- ymptote," or tangental value toward which this fourth curve tends, is easily seen. This represents the true ground system resistance. Please refer once again to the attached drawing .AGC -023 -233 (Appendix C), for an example of such a graph. 6SPS I150E62-0 17 18 6SP81150E62-0 APPENDIX B — Document References uriuur UINti IiUIUtLINt The following references were used in preparing this document, and provide further information on the subject: AC Service Grounding Engineering Application, GTE Practices section 795- 805 -072 Controlling Lightning Damage at Radio Sites, by Richard Little, Principle Staff Engineer, Motorola Radio-Telephone Sys- tems Group Electrical Protection of Electronic Analog and Digital Central Office Equipment, ALLTEL.
