GENERAL PROVISIONS 2.01 Engineer's Status and Authority. It is mutually agreed by and between the parties to this Contract that the Engineer shall have general supervision and direction of the work included herein. In order to prevent delays and disputes and to discourage litiga- tion it is further agreed by and between the parties of this Contract that the Engineer shall in all cases determine the amounts and quantities of the several kinds of work which are to be paid for under the Con- tract; that he shall determine all questions in rela- tion to said work and the construction thereof, that he shall in all cases decide every question which may arise relative to the execution of the Contract on the part of the Contractor; that his decisions and find- ings shall be the conditions precedent to the right of the parties hereto to arbitration or to any action on the Contract and to the rights of the Contractor to receive any money under this Contract; provided, how- ever, that should the Engineer render any decision or give any direction 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 30 days a written objection to the decision or direction so rendered. It is the intent of this Agreement that there shall be no delay in the execution of the work, and the decision or directions' of the Engineer as rendered shall be promptly carried out. 2.02 Right of Engineer to Modify Methods and Equipment. If at any time the methods or equipment used by the Con- tractor are found to be unsafe or inadequate to secure the quality of the work or the rate of progress re- quired under this Contract, the Engineer may direct the Contractor in writing to increase their safety or improve their character and efficiency and to cease operations under this Contract until such direction is complied with. No claims shall be made against the Owner for damages caused by any delay resulting from such order. -3- 2.03 Changes and Alterations. The Contractor agrees that the Owner, through the Engineer, 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 bonds. If such changes or altera- tions 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. If they increase the amount of work and the increased 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 established for such work under this Con- tract; otherwise such work shall be paid for as pro- vided under Section 2.12 "Extra Work ". In the event the Owner shall make such changes or alterations which will make useless any work already done or material already furnished or used in said work, then the Owner shall compensate the Contractor for any materials or labor so used, for any actual loss occasioned by such change, and for the actual expenses incurred in prepa- ration for the work as originally planned. 2.04 Damages. The right of general supervision by the Owner shall not make the Contractor an agent of the Owner, and the liability of the Contractor for all damages to persons, firms, and corporations arising from the Contractor's execution of the work shall not be lessened because of such general supervision. The Contractor is an independent contractor in regard to work under this Contract, and as such is solely liable for all damages to any persons, firms, corporations, or their property as a result of the prosecution of the work. 2.05 Losses from Natural Causes. All loss or damage aris- ing out of the nature of the work to be done or from the action of the elements or from any unforeseen cir- cumstances in the prosecution of the work or from unu- sual obstructions or difficulties which may be encoun- tered in the prosecution of the work shall be sustain- ed and borne by the Contractor at his own cost and expense. 2.06 Laws and Ordinances. The Contractor shall at all times observe and comply with all Federal, State, and local laws, ordinances, rules and regulations which -4- in any manner affect the Contract or the work and shall indemnify and save harmless the Owner against any claim arising from the violation of any such laws and ordinances whether by the Contractor or his em- ployees or his subcontractors and their employees. 2.07 Licenses, Permits and Certificates.

It is further agreed that it is the intent of this Contract that all work must be done and all material must be furnished in ac- cordance with the generally accepted practice, and in the event of any discrepancies between the separate contract documents, the priority of interpretation de- fined under "Contract Documents" shall govern. In the event that there is still any doubt as to the meaning and intent of any portion of the Contract, Specifica- tions or Drawings, the Engineer shall define which is intended to apply to the work. 2.11 Contractor's Understanding. It is understood and agreed that the Contractor has, by careful examina- tion, satisfied himself as to the nature and location -5- of the work, the conformation of the ground, the char- acter, quality and quantity of the materials to be en- countered, 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 affect the work under this Contract.

It is agreed that the Contractor shall perform all extra work under the direction of the Engineer when presented with a written Change Order signed by the Engineer. 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, he shall make a written request to the Engineer for a written Change Order authorizing such extra work. Should a difference of opinion arise as to what does or does not constitute extra work or concerning the payment therefor and the Engineer insists upon its performance, the Contractor shall proceed with the work after making a written request for a written Change Order and shall keep an accurate account of the "actual field cost" thereof as provided under Method "C" below. 2.13 Payment for Extra Work. It is agreed that the compen- sation to be paid the Contractor for performing extra work shall be determined by one or more of the follow- ing methods: Method "A" - By agreed unit prices; Method "B" - By agreed lump sum; or Method "C" - If neither Method "A" or Method "B" can be agreed upon before the extra work is commenced, then the Contractor shall be paid the "actual field cost" of the work plus 15 %. Where extra work is performed under Method "C ", the term "actual field cost" of such extra work is hereby defined to be and shall include: (a) the payroll cost for all workmen, such as foreman, mechanics, crafts- men, and laborers; (b) the cost of all materials and supplies not furnished by the Owner; (c) rental for all power- driven equipment at agreed -upon rates for the time actually employed or used in the performance of the extra work; (d) transportation charges neces- sarily incurred in connection with any equipment authorized by the Engineer for use on said extra work and which is not already on the job; (e) all power, fuel, lubricants, water, and similar operating expens- es; (f) all incidental expenses incurred as a direct result of such extra work including sales or use taxes . on materials, payroll taxes, and the additional pre- miums for construction bonds, workmen's compensation, public liability and property damage, and other insur- ance required by the Contract where the premiums therefor are based on payroll and material costs. The Engineer may direct the form in which accounts of the "actual field costs" shall be kept and may also speci- fy 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 equip- ment shall be incorporated in the written extra work Change Order. The 15% of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, and general superinten- dence. 2.14 Assignment and Subletting. The Contractor shall not assign or sublet the work or any part thereof without the previous written consent of the Owner, nor shall he assign, by power of attorney or otherwise, any of the money payable under this Contract unless by and with the consent of the Owner to be signified in like manner.

The Contractor shall be as fully re- sponsible to the Owner for the acts and omissions of his subcontractors and of persons either directly or indirectly employed by them as he is for the acts and omissions of persons directly employed by him.

Nothing contained in this Contract shall create any contractual relation between any sub- contractor and the Owner. 2.17 Completed Portions of Work. The Owner shall have the right to take possession of and to use any completed or partially completed portions of the work prior to completion of the entire work, but such use shall not constitute an acceptance of any of the work not com- pleted in accordance with the Contract Documents. If the Engineer determines that taking possession of and using partially completed work substantially increases the cost of or delays construction, the Contractor shall be entitled to extra compensation or extension of time or both as determined by the Engineer.. 2.18 Materials.

The Contractor shall not start delivery of materials which he is to furnish until the Engineer has approved the source of supply of such materials. 2.19 Receiving and Storage of Materials.

It is the meaning and intent of this Contract, unless otherwise herein specifically provided, that the Contractor shall be allowed to prosecute his work at such times and sea- sons in such order of precedence and in such manner as shall be most conducive to economy of construction; -15- provided however, that the order and time of prosecu- tion shall be such that the work shall be substantial- ly completed as a whole or in part in accordance with this Contract within the time of completion hereafter designated; provided also that the Engineer may direct the time and manner of constructing any part or parts of the work when in his opinion such should be given priority to lessen the probability of danger to the public or to anticipate seasonal hazards from the ele- ments or to coordinate with other work being done for or by the Owner. 5.02 Rate of Progress. The Contractor shall give the Engi- neer full information in advance as to his plans for carrying on any part of the work. If at any time prior to the start or during the progress of the work any part of the Contractor's plant or equipment or any of his methods of executing the work appear to the Engineer to be unsafe, inefficient, or inadequate to insure the required quality or rate of progress of the work, the Engineer may order the Contractor to in- crease or improve his facilities or methods, and the Contractor shall promptly comply with such orders; but neither compliance with such orders nor failure of the Engineer to issue such orders shall relieve the Con- tractor from his obligation to secure the degree of safety, the quality of work, and the rate of progress required by this Contractor. The Contractor alone shall be responsible for the safety, adequacy, and efficiency of his plant, equipment, and methods. 5.03 Sunday, Holiday, and Night Work. Except in connection with the care, maintenance, or protection of equipment or of work already done, no work shall be done between the hours of 6:00 p.m. and 7:00 a.m. or on Sundays or legal holidays without written consent of the Engi- neer. 5.04 Hindrances and Delays. No claims shall be made by the Contractor for damages, hindrances, or delays from any cause during the progress of any portion of the work embraced by this Contract except where the work is stopped by order of the Owner. If the Owner stops the work for just cause because the Contractor is not com- plying with the plans and specifications or the intent thereof, the Contractor shall have no claim for dam- ages, hindrances, or delays. However, if the Owner stops the work for any other reason, the Contractor shall be entitled to reimbursement paid by the Owner for such expenses actually incurred which in the judg- ment of the Engineer occurred as a result of the work stoppage. -16- Should delays repeatedly occur due to the Contractor's failure to provide adequate plant, equipment, or per- sonnel, or where the Engineer determines that unrea- sonable inconvenience to the public is due to such failure, the Contractor's operations shall be suspend- ed until he shall have provided adequate plant, equip- ment, and personnel to properly resume and continually prosecute the work. 5.05 Extensions of Time. Should the Contractor be delayed in the final completion of the work by any act or neg- lect of the Owner or Engineer, or of any employee of either, or by any other contractor employed by the Owner, or by strikes, fire or other cause or causes outside of and beyond the control of the Contractor and which the Engineer determines could have been neither anticipated nor avoided, then an extension of time sufficient to compensate for the delay as deter- mined by the Engineer shall be granted by the Owner; provided, however, that the Contractor shall give the Owner prompt notice in writing of the cause of delay in each case. Extensions of time will not be granted for delays caused by unfavorable weather, unsuitable ground conditions or inadequate construction force. 5.06 Liquidated Damages for Failure to Complete on Time. The Contractor agrees that time is of the essence of this Contract and that the definite value of damages which would result from delay would be incapable of ascertainment and uncertain, so that for each day of delay beyond the number of days herein agreed upon for the completion of the work herein specified and con- tracted for, after due allowance for such extension of time as is provided for under the provisions of the preceding paragraph, the Owner may withhold permanent- ly from the Contractor's total compensation, not as a penalty but as liquidated damages, the sum per day given in the following schedule: Amount of Liquidated Amount of Contract Damages Per Day Less than $ 5,000.00 $ 5,001.00 to $ 15,000.00 15,001.00 to 25,000.00 25,001.00 to 50,000.00 50,001.00 to 100,000.00 100,001.00 to 500,000.00 500,001.00 to 1,000,000.00 1,000,001.00 to 2,000,000.00 2,000,001.00 to 5,000,000.00 -17- $ 30.00 35.00 40.00 50.00 70.00 200.00 300.00 400.00 500.00 6.

This Certificate of Insur- ance shall be provided to the Owner prior to starting any construction work in connection with this Con- tract. 7. TERMINATION OF CONTRACT 7.01 Right of Owner to Terminate. If the Contractor should be guilty of substantial violation of the Contract or any provision thereof, the Owner, upon certification by the Engineer as to the nature and extent of such violation, may without prejudice to any other resourc- es or remedy give the Contractor written notice of termination of the employment of the Contractor 10 days subsequent to such notice. Immediately following such date the Owner may take possession of the site of the work and all material, equipment, tools, and ap- pliances thereon and may finish the work in accordance with the provisions of Section 8 "Abandonment of Con- tract by Contractor ", of these General Conditions. 7.02 Right of Contractor to Terminate. If work should be stopped by order of any public authority or court through act or fault of the Contractor for a period of three (3) months or if the Owner should substan- tially fail to perform the provisions of the Contract with regard to Owner's obligations to the Contractor, then the Contractor may, upon 10 days written notice to the Owner, terminate this Contract and recover from the Owner payment for all completed work. 7.03 Removal of Equipment. In the event that the Contract should be terminated for any reason whatsoever, the Owner may request the Contractor in writing to remove any or all of his equipment, tools, and supplies, and the Contractor shall comply with the request within 10 days after receipt of the notice. Should he fail to do so within 10 days after receipt of such notice, the Owner shall have the right to remove such equipment and supplies at the expense of the Contractor and to place such equipment, tools and supplies in storage at the risk and expense of the Contractor. 8. ABANDONMENT OF CONTRACT BY CONTRACTOR 8.01 Notification of Contractor. If the Contractor should abandon and fail to refuse to resume work within 10 -20- days after written notification from the Owner or the Engineer or if the Contractor fails to comply with the orders of the Engineer when such orders are consistent with this Contract or with the specifications hereto attached, then the Contractor shall be deemed as hav- ing abandoned the Contract. In such event the Surety on the bond shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. 8.02 Retention of Contractor's Equipment and Materials by Owner. After receiving said notice of abandonment the Contractor shall not remove from the work any machin- ery, 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 per- formance bond or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefor except when used in connec- tion with extra work where credit shall be allowed as provided for under Section 2.12 entitled "Extra- Work ", it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and will be reflected in the final settle- ment. 8.03 Methods of Completing the Work. If the Surety should fail to commence compliance with the notice for com- pletion hereinbefore provided within 10 days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: a. The Owner may thereupon employ such force of work- ers and use such machinery, equipment, tools, mat- erials, and supplies as said Owner may deem 'neces- sary to complete the work and charge the expense of such labor, machinery, equipment, tools, mater- ials, and supplies to said Contractor, and the ex- pense so charged shall be deducted and paid by the Owner out of such monies as may be due or that may thereafter at any time become due to the Contrac- tor under and by virtue of this Contract. 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 Con- tractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this Contract if the same -21- had been completed by said Contractor, then the Contractor or his Surety shall pay the amount of such excess to the Owner. b. The Owner under sealed bids, after 14 days notice published two or more times in a newspaper having a general circulation in the county of location of the work, 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 of 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 new contract prove to be less than what would have been the cost to complete under this Contract, the Contrac- tor or his Surety shall be credited therewith. 8.04 Final Acceptance. When the work has been completed the Contractor and his Surety shall be so notified and a Contract Completion Certificate as hereinafter pro- vided shall be issued. A complete itemized statement of the Contract accounts certified by the Engineer as being correct shall then be prepared and delivered to the Contractor and his Surety, whereupon the Contrac- tor, his Surety or the Owner, as the case may be, shall pay the balance due as reflected by said state- ment within 15 days after the date of such Contract Completion Certificate. 8.05 Disposition of Contractor's Equipment. In the event the statement of accounts shows that the cost to com- plete 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 or his Surety pay the balance shown to be due by them to the Owner, then all machin- ery, equipment, tools, materials, or supplies left on the site of the work shall be turned over to the Con- tractor or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there re- mains any machinery, equipment, tools, materials,'or supplies on the site of the work, notice thereof to- gether 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 -22- 1 Contract; provided, however, that actual. written 1 notice given in any manner will satisfy this condi- tion. After mailing or other giving of such notice such property shall be held by the Owner 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 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 pub- lic or private sale, with or without notice, as the Owner may elect. The Owner shall release any machin- ery, 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. 1 9. MEASUREMENT AND PAYMENT 9.01 Character of Measurements. No extra or customary measurements of any kind will be allowed, but the actual length, area, solid contents, number, and weight only shall be considered unless otherwise spe- cifically provided. 9.02 Estimated vs. Actual Quantities. Any and all estimat- ' ed quantities stipulated in the proposal form under unit price items are approximate and are to be used only (a) as a basis for estimating the probable cost of the work and (b) for the purpose of comparing the proposals submitted for the work. It is understood and agreed that the actual amounts of work done and ' materials furnished under unit price items may differ from such estimated quantities and that the basis of payment for such work and materials shall be for the actual amount of such work done and the actual quan- tity of materials furnished. The Contractor agrees that he will make no claim for damages, anticipated profits, or otherwise on account of any difference between the amounts of work actually performed and materials actually furnished and the ' amounts estimated therefor in the proposal or other Contract Documents; provided, however, that if the actual quantity of any item should become as much as 25 percent more than or 25 percent less than the esti- mated or contemplated quantity for such items, then either party to this Contract shall be entitled upon demand to a revised consideration on the portion of -23- the work above or below 25 percent of the estimated quantity prior to initiating work or furnishing mater- ials for the overrun or underrun quantities. Such re- vised consideration shall be determined by agreement between the parties or otherwise by the terms of this Contract as.provided under Section 2.12 entitled "Extra Work ". 9.03 Payment. 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 the delivery of all mater- ial embraced in this Contract in full conformity with the specifications and stipulations contained herein, the Owner agrees to pay the Contractor the amounts set forth in the Proposal attached hereto which has been made a part of this Contract. The Contractor hereby agrees to receive such amounts in full payment for furnishing all material and all labor required for the aforesaid work, for all expense incurred by him, and for well and truly performing the same and the whole thereof in the manner and according to this Contract, the attached specifications, and requirements of the Engineer. 9.04 Monthly Estimates and Payments. On or about the fifth day of each month the Engineer will make an approxi- mate estimate of the value of work done in conformity with the plans and specifications during the previous calendar month. The Contractor shall furnish to the Engineer such detailed information as he may request to aid him as a guide in the preparation of monthly estimates. After each such estimate shall have been approved by the Owner, the Owner shall pay to the Con- tractor 90 percent of the amount of such estimated sum on or before the 15th day of said month. It is understood, however, that in case the whole work is near to completion and some unexpected or unusual delay occurs due to no fault or neglect on the part of the Contractor, the Owner may, upon written recommen- dation of the Engineer, pay a reasonable and equitable • portion of the retained percentage to the Contractor. 9.05 Certificates of Completion. Within 10 days after the Contractor has given the Engineer notice that the work has been completed the Engineer shall inspect the work and satisfy himself by examination and test that the work has been finally and fully completed in accor- dance with the plans, specifications and Contract. If -24- so, the Engineer shall issue a Contract Completion Certificate to the Owner and the Contractor. Such certificate when issued shall constitute final accep- tance of the work covered under this Contract. 9.06 Final Estimate and Payment. After the Contract Com- pletion Certificate has been issued the Engineer shall proceed to make final measurements and to prepare a final estimate of the work done and materials furnish- ed under this Contract and the value thereof. The Engineer shall certify the Final Estimate and submit it to the Owner within five (5) days from the date of the Contract Completion Certificate. The Owner shall pay the Contractor within 15 days from the date of the Contract Completion Certificate the entire sum shown due on the. certified Final Estimate prepared by the Engineer after deducting all amounts to be kept and retained under any provision of this Contract. However, it is to be specifically under- stood that the final payment will not be paid by the Owner to the Contractor under any circumstances until the Notarized Affidavit required by Section 9.07 en- titled "Notarized Affidavit ", has been submitted to the Engineer. All prior estimates and payments shall be subject to correction in the final estimate and payment; but in the absence of error or manifest mistake, it is agreed that all estimates, when approved by the Owner, shall be conclusive evidence of the work done and materials furnished. 9.07 Notarized Affidavit. Before final payment for the work by the Owner the Contractor shall submit to the Engineer a notarized affidavit in duplicate stating under oath that all subcontractors, vendors, and other persons or firms who have furnished or performed labor or furnished materials for the work have been fully paid or satisfactorily secured. Such affidavit shall bear or be accompanied by a statement, signed by the Surety Company who provided the performance bond for the work, to the effect that said Surety Company con- sents to final payment to the Contractor being made by the Owner. 9.08 Release of Liability. The acceptance by the Contrac- tor of the last payment shall operate as and shall be a release to the Owner and every officer and agent thereof from all claims and liability hereunder for anything done or furnished for or relating to the work or for any act or neglect of the Owner or of any per- son relating to or affecting the work. -25- 9.09 Contractor's Obligation. Neither the Contract Comple- tion Certificate nor the final payment nor any provi- sion in the Contract Documents shall relieve the Con- tractor of the obligation for fulfillment of any war- ranty which may be required in the Contract Docu- ments. 9.10 Payments Withheld. The Owner may, on account of sub- sequently discovered evidence, withhold or nullify the whole or part of any payment to such extent as may be necessary to protect himself from loss on account of: a. Defective work not remedied. b. Claims filed or reasonable evidence indicating probable filing of claims. c. Failure of the Contractor to make payments proper- ly to subcontractors or for material or labor. d. Damage to another contractor. 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. -26- SPECIAL CONDITIONS OF AGREEMENT SPECIAL CONDITIONS OF AGREEMENT SECTION 01 - INFORMATION 01 -01 ENGINEER The word "Engineer" in these Specifications shall be understood as referring to Haynie & Kallman, Inc., 2115 N.

The Contractor shall, at his own expense, maintain the street free from dust, mud, excess earth or de- bris which constitutes a nuisance or danger to the public using the thoroughfare, or the occupants of adjacent properties. Care shall be taken to prevent spillage on streets over which hauling is done, and any such spillage or debris deposited on streets, due to the Contractor's operations, shall be immediately removed. 01 - BACRWORK The Contractor shall coordinate his operations in such a manner as to prevent the amount of clean -up and completion of back works from becoming exces- sive. Should such a condition be existent, the Engineer may order all or portions of the work to cease and refuse to allow any work to commence until the back work is done to the Engineer's satisfac- tion. 01 -04 GRADING The Contractor shall do such grading in the area adjacent to backfilled trenches and structures as may be necessary to leave the area in a neat and satisfactory condition approved by the Engineer. 01 -1/4 9/80 01 -05 SURFACE DRAINAGE All grading in the vicinity of trench excavation shall be controlled to prevent surface water from flowing into the trenches. Any water accumulated in the trenches shall be removed by pumping or by other approved methods. 01 -06 BACKFILL During excavation, material suitable for backfilling shall be piled in an orderly manner, a sufficient distance back from the edges of trenches, to avoid overloading and to prevent slides or cave -ins. Materials unsuitable for backfilling shall be hauled from the job site and disposed of by the Contrac- tor. Where the Plans and /or Special Provisions provide for segregation of top soil from underlying material for purposes of backfill, the materials shall not be mixed. 01 -07 INSPECTION OF WORK The work covered under this Contract shall be in- spected by the Engineer or the Owner's authorized representative. The quality of material and the quality of installation of pipe and related equip- ment shall be to the satisfaction of the Inspector.. It shall be the Contractor's responsibility for the construction methods and safety precautions in the undertaking of this Contract. 01 -08 NOTIFICATION The Engineer must be notified a minimum of 24 -hours in advance of beginning construction. 01 -09 CONSTRUCTION STAKING The Engineer has staked the sewer alignment and pro- vided reference hubs and bench marks at the treat- ment plant site. The Contractor shall provide his own construction staking. 01 -2/4 9/80 01 -10 TESTING AND ACCEPTANCE OF IMPROVEMENTS The Engineer or his representative will be present at the testing of water and sewer lines. The Con- tractor will test all lines and be confident that the lines will be able to pass test prior to calling the Engineer to observe test. No lines will be ac- cepted by the Owner without the Engineer observing the test and certifying to the lines passing the pressure tests as specified herein. 01 - 11 WORK IN FREEZING WEATHER Portions of the work may continue as directed by the Engineer. 01 - PROTECTION OF TREES, PLANTS AND SHRUBS The Contractor shall take necessary precautions to preserve all existing trees, plants and shrubs but where it is justifiable and necessary, the Contrac- tor may remove trees and plants for construction right -of -way but only with prior approval of the Engineer. 01 -13 BARRICADES Barricades shall be installed, in locations deemed necessary by the Engineer, for the protection of life and property. Under no circumstances will any existing road be permitted to remain closed over a weekend. 01 - PROPERTY LINES AND MONUMENTS The Contractor shall be responsible for the protec- tion, reference and resetting of property corner monuments if disturbed. 01 -15 DISPOSAL OF SURPLUS MATERIAL The Contractor shall at his own expense make ar- rangement for the disposal of surplus material, such as rock, trees, brush and other unwanted backfill materials. 01 -16 CONTRACTOR'S USE OF PREMISES The Contractor shall, at his own expense, provide additional space as necessary for his operations and storage of materials. 01 -3/4 9/80 01 -17 TRADE NAMES Except as specified otherwise, wherever in the Specifications an article or class of material is designated by a trade name or by the name or catalog number of any maker, patentee, manufacturer, or dealer, such designations shall be taken as intend- ing to mean and specify the articles described or another equal thereto in quality, finish, and ser- viceability for the purpose intended, as may be determined and judged by the Engineer in his sole discretion. 01 -18 MATERIALS AND WORKMANSHIP No material which has been used by the Contractor for any temporary purpose whatever is to be incor- porated in the permanent structure without written consent of the Engineer. Where materials or equip- ment are specified by a trade or brand name, it is not the intention of the Owner to discriminate against an equal product of another manufacturer, but rather to set a definite standard of quality for performance, and to establish an equal basis for the evaluation of bids. Where the words "equivalent ", "proper ", or "equal to" are used, they shall be understood to mean that the item referred to shall be proper, the equivalent of, or equal to some other item, in the opinion or judgment of the Engineer. Unless otherwise specified, all materials shall be the best of their respective kinds and shall be in all cases fully equal to approved samples. Notwith- standing that the words "or equal to" or.other such expressions may be used in the specifications in connection with a material, manufactured article or process, the material, article or prices specifical- ly designated shall be used, unless a substitute shall be approved in writing by the Engineer, and the Engineer shall have right to require the use of such specifically designated material, article or process. 01 -19 MEASUREMENT AND PAYMENT No separate payment for work performed under this item. Include cost of same in contract price bid for items of which this work is a component. 01 -4/4 9/80 1 SECTION 02 EARTHWORK 1 02 -01 GENERAL Earthwork shall consist of clearing, grubbing, loosening, blasting, rock excavation, removing, transporting, depositing, compacting, trenching, backfilling in final location all materials, wet or dry as required for construction; together with furnishing, placing and removing of all sheeting and bracing; and all pumping and draining of exca- vation. 02 -02 CLEARING AND GRUBBING 02 -02:1 General This work shall consist of removing all natural and artificial objectionable material from the right - of -way, construction areas and such other areas as may be specified. Clearing and grubbing shall be performed in advance of grading operations and in accordance with the requirements herein specified, subject to erosion control requirements. Demoli- tion of buildings and structures, other than foun- dations or slabs, shall be as specified on the plans. 02 -02.2 Preservation of Property Existing improvements, adjacent property, utility and other facilities, and trees and plants are not to be removed, and shall be protected from injury or damage resulting from the Contractor's opera- tions. 02 -02.3 Clearing and Grubbing Operations Unless otherwise specified, the entire area of the project to the widths specified below shall be cleared and grubbed. No payment will be made to the Contractor for clearing and grubbing outside these limits, unless such work is authorized by the Engineer. The area above the natural ground surface shall be cleared of all vegetable growth, such as trees, logs, upturned stumps, roots of downed trees, brush, grass, weeds, and all other objectionable material, within the limits of the roadways and yard area. 02 -1/13 9/80 Trees and plants that are not to be removed shall be fully protected from injury by the Contractor at his expense. 02 -03 PROTECTION OF EXISTING STRUCTURES AND UTILITIES Existing power and telephone lines, trees, fences, pipelines or other conduits, and structures in the vicinity of the work shall be supported and pro- tected from injury by the Contractor during the construction and until the completion of the work. The Contractor shall be liable for all damages to such structures, as herein provided, and shall save and keep the Owner harmless from any liability or expense for injuries, damages, or repairs to same. A thorough attempt has been made to show the type, size, location and number of all utilities, how- ever, no guarantee is made as to the location and number of utilities. The Contractor shall repair, in a manner satisfactory to the Engineer, all util- ities damaged in the progress of his work. The Contractor shall notify all owners of utilities prior to commencement of and sufficiently in ad- vance to have the utilities mark the location of their facilities. The Contractor shall be prepared at all times with labor,•equipment, and materials to make repairs to damaged. mains or utilities. 02 -04 MAINTAINING DRAINAGE The Contractor shall provide and maintain temporary drainage for all excavations, drains, ditches, trenches, and structures. The Contractor shall keep the excavations dry through the construction operations. Whenever necessary, in order to pro- vide proper drainage, the Contractor shall, at his own expense, install underdrains, furnish and ope- rate all necessary pumping equipment, drainage sumps, wellpoint systems and other drainage facil- ities. The Contractor shall dispose of the water from the work into a drainage channel without damage to ad- jacent property and in such a manner as not to be a menace to the public health. No water shall be drained into completed work or work under construc- tion without prior consent of the Engineer. 02 -2/13 9/80 02 -05 BLASTING The Contractor shall provide, without additional compensation, suitable temporary channels or other work for the water that may flow along or across the site of the work. Blasting for excavation will be permitted only after securing the approval of the Engineer and only when proper precautions are taken for the pro- tection of persons and property. The hours of blasting will be fixed by the Engineer. Any damage caused by blasting shall be repaired by the Con- tractor at his expense. The Contractor shall carry proper and adequate blasting insurance. The Contractor's methods of procedure in blasting shall conform to federal, state, and local laws. 02 -06 PILING EXCAVATED MATERIAL All excavated material shall be piled in a manner that will not endanger the work and that will avoid obstructing roads and driveways. Hydrants under pressure, valve pit covers, valve boxes, curb stop boxes, fire and police call boxes, or other utility controls shall be left unobstructed and accessible until the work is completed. Gutters shall be kept clear or other satisfactory provisions made for street drainage. Natural watercourses shall not be obstructed. 02 -07 SHORING, SHEETING AND BRACING Where necessary, trenches and other excavations shall be properly sheeted and braced to furnish acceptable working conditions. The bracing shall comply in all respects to the rules, orders, and regulations prescribed by federal, state and local laws. When required by law, the Contractor shall submit to the Engineer detailed drawings of propos- ed bracing. 02 -08 SEASONAL LIMITS No fill material shall be placed, spread, or com- pacted during unfavorable weather conditions. When the work is interrupted by snow or rain, filling operations shall not be resumed until field tests 02 -3/13 9/80 I 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 by the Engineer indicate that the moisture content and density of the fill are as specified. 02 -09 CONTROL OF DUST The Contractor shall, at all times, keep the con- struction area watered or swept of all loose mater- ial produced by his operations in order that traf- fic and construction do not raise an objectionable amount of dust. When conditions warrant, the Con- tractor shall apply a suitable dust palliative to control dust. 02 -10 BARRICADES, GUARDS, AND SAFETY PROVISIONS To protect persons from injury and to avoid proper- ty damage, adequate barricades, construction signs, torches, red lanterns, and guards, as required, will be placed and maintained during the construc- tion. All material piles, equipment, and pipe which may serve as obstructions to traffic shall be enclosed by fences or barricades and shall be pro- tected by proper lights when the visibility is poor. The rules and regulations of the local authorities respecting safety provisions shall be observed. 02 -11 EXCESS MATERIAL Excess excavation material shall be promptly remov- ed and disposed of on the site by the Contractor as directed by the Engineer. The Contractor shall not dump material on any private property without the written permission of the Owner thereof. 02 -12 TRENCH EXCAVATION 02 -12.1 Trenching Trenches shall be of such extra width, when requir- ed, as will permit the convenient placing of timber supports, sheeting and bracing, and handling of specials. All excavations for pipes shall be of a depth to permit at least a thirty inch (30 ") cover- ing over the pipe unless otherwise shown. All trenches shall have vertical sides from the bottom to a point at least twelve inches (12 ") above the top of the pipe. Above this point in unstable ground, with the written consent of the Engineer, the trench banks may be sloped as directed. 02 -4/13 9/80 Bell holes shall be provided at each joint to per- mit the jointing to be made properly, unless other- wise approved by the Engineer. The bottom of trench must be free from loose mater- ial before placing the subgrade material. Whenever the maximum allowable trench width is exceeded for any reason, the Contractor shall, at his expense, embed or cradle the pipe in concrete in a manner satisfactory to the Engineer. 02 -12.2 Pipe Clearance in Rock Ledge rocks, boulders, and large stones shall be removed to provide a clearance of not less than six inches (6 ") below and on each side of all pipe, valves, and fittings. 02 -12.3 Excavation in Poor Soil and Refilling to Grade Where the bottom of the trench at subgrade is found to be unstable or to include ashes, cinders, any type of refuse, vegetable or other organic mater- ial, or large pieces of fragments or inorganic material which, in the judgment of the Engineer are unsuitable, the Contractor shall excavate and re- move such unsuitable material to the width and depth ordered by the Engineer. Before the pipe is laid, the subgrade shall be made by backfilling as provided herein. Payment for over excavation and refilling to grade will be made in accordance with the General Condi- tions. Unsuitable excavation shall be removed from the project. 02 -12.4 Braced and Sheeted Trenches Open -cut trenches shall be sheeted and braced as required by applicable regulations, and as may be necessary to protect life, limb, property, or the work. When close sheeting is required by trench conditions, it shall be so driven as'to prevent ad- jacent soil from entering the trench below or through such sheeting. Where sheeting and bracing are used, the trench width shall be increased ac- cordingly. The Engineer reserves the right to order the sheet- ing driven to the full depth of the trench or to 02 -5/13 9/80 such additional depths which are required for the protection of the work. Where the soil in the lower limits of a trench has the necessary stabil- ity, the Engineer, at his discretion, may permit the Contractor to stop the driving of sheeting at some designated elevation above the trench bottom. Any sheeting driven below the invert grade shall be left in place. The granting of such permission by the Engineer, however, shall not relieve the Con- tractor in any degree from his full responsibility under the Contract. Sheeting and bracing which are left in place must be removed for a distance of three feet (3') below the established finished grade or the existing sur- face, whichever is lower. Trench bracing, except that which must be left in place, may be removed when the backfilling has reached the respective levels of such bracing. Sheeting, except that which must be left in place, must be removed after the backfilling has been completed or has been brought up to such an elevation as to permit its safe removal. Sheeting and bracing may be removed before backfilling but only in such manner as will insure the adequate protection of the adjacent structures. 02 -13 TRENCH BACKFILL 02 -13.1 General Pipeline trenches shall be backfilled with desig- nated materials to the level of the original ground surface, to the underside of the ground base course, to the finished grade, or as shown on the drawings. Before backfilling, the trench shall be cleared of all timber and debris. Backfill shall be compacted to 85% relative density except as otherwise provided herein. It is highly important that a dense, well- compacted backfill be placed around the pipelines. The Con- tractor will be required to produce such a backfill under all circumstances. The materials used for the backfill, the amount thereof, and the manner of deposition shall be subject to the approval of the Engineer, but the Contractor will be held respons- ible for any displacement or instability of the pipeline or any damage to the coating caused by im- proper installation of backfill materials. No 02 -6/13 9/80 material shall be used for trench backfill, which, for any reason cannot be compacted to the degree specified. For these specifications, backfill shall be divided into two (2) categories: Bedding and Upper Zone Backfill. Bedding shall be defined as that mater- ial supporting and extending to one foot (1') above the top of the pipe. Where concrete is specified to cover the pipe, the top of the concrete shall be considered as the top of the bedding. Upper zone backfill shall be defined as that material placed in the trench from the top of the bedding to the upper limit of backfill required. 02 -13.2 Bedding. In soft, spongy, unstable, or other similar mater- ial is encountered upon which the bedding material or pipe is to be placed, this unsuitable material shall be removed to a depth ordered by the Engineer and replaced with bedding material suitably densi- fied. Additional bedding so ordered, over the above amount required by the plans or specifica- tions, will be paid for as provided in the General Conditions. If the necessity for such additional bedding materials has been caused by an act or failure to act on the part of the Contractor, or is required for the control of ground water, the Con- tractor shall bear the expense of the additional excavation and bedding. Bedding material shall first be placed so that the pipe is supported for the full length of the barrel with full bearing on the bottom segment of the pipe equal to a minimum of 0.4 of the outside diameter of the barrel. Then the remainder .of the bedding shall be placed. Alternate methods of pipe laying which are recommended by the pipe manufacturer may be used if approved by the Engineer. Except where otherwise specified, bedding material shall be sand, gravel, disintegrated granite, crushed aggregate, native free - draining granular material having a sand equivalent of not less than 30 or having a coefficient or permeability greater than 0.001 Cm. per Sec., or other material approved by the Engineer. Unless otherwise specified, con- crete used for bedding shall be Class 5.0 -B -2000. 02 -7/13 9/80 In cases where native free - draining granular mater- ial is suitable for use as bedding, the trench may be excavated to a point above the invert grade and the trench bottom hand - shaped so that the bottom segment of the pipe is firmly supported on undis- turbed material. The pipe bedding over the top of the pipe shall be compacted to 90 percent relative compaction unless otherwise shown on the drawings. 02 -13.3 Upper Level Backfill Backfill material for the upper level backfill zone of the pipe trench shall be native material com- pacted to 85 percent relative compaction. In roadway or parking areas, all backfill shall be compacted to 90 percent relative compaction. Jetting (water consolidation of backfill) shall be used only when approved by the Engineer. The jet pipe shall be not less than one and one -half (1 -1/2) inches in diameter and shall extend to within fifteen inches (15 ") of the top of the pipe during jetting of backfill over pipe. The source of water for jetting shall be a water tank with a pressure of sixty pounds (60) per square inch. All "bridges" shall be completely broken down during the jetting process. Jet points along the line of the ditch shall be staggered from side to side at intervals not to exceed six feet (6') center to center or as necessary so that the takes full possible subsidence while water is being in- troduced into it through the jet pipe. If the com- paction requirements specified above are not met within 60 calendar days after jetting the backfill, the trench shall be re- excavated. Backfill mater- ial shall then be compacted by tamping and /or roll- ing until the compaction requirements are satis- fied. 02 -14 STRUCTURAL EXCAVATION AND BACRFILL 02 -14.1 Excavation The Contractor may employ any method of excavation that he desires which, in his experience, he con- siders to be the best, providing it meets with the approval of the Engineer. The ground shall not be 02 -8/13 9/80 dug by machinery nearer than three inches (3 ") of any finished subgrade without the express consent and approval of the Engineer. The last three inch- es (3 ") shall be removed by such methods acceptable to the Engineer, and shall not disturb or weaken any subgrade for foundation purposes. Excavations for footing, floor slabs, and other structures shall be carried to the neat outside lines of such structures, as shown on the drawings, plus one inch (1 ") in all horizontal directions, and the concrete to be poured therein shall be placed on or against the original undisturbed material whenever such a procedure is reasonably possible and expedient. If this is not possible, the earth on which the concrete is to be poured shall be compacted to a uniform density of not less than ninety percent (90 %) of the maximum density. Excavations for walls, where forms are used, shall extend a sufficient distance to allow for placing and removal of forms, installations of services, and inspection of work. Structure excavation carried beyond or below the lines and grades indicated on the drawings shall be refilled with approved materials and compacted as directed by the Engineer at the expense of the Con- tractor, except that under footings, concrete shall be used. 02 -14.2 Backfilling All lumber, rubbish and braces shall be carefully removed from excavations. Unless otherwise speci- fied, all excavations shall then be backfilled with imported material up to the original surface of the ground, or to such grades as shall be directed. The backfilling shall be done as completely as pos- sible in such manner as to prevent after- settle- ment. No backfill shall be placed against concrete walls until the walls have been inspected and approved by the Engineer. Shoring and sheeting shall be care- fully and completely removed as the backfilling progresses, unless otherwise authorized by the Engineer. Where sheeting is left in place, all cavities behind such sheeting shall be solidly filled. 02 -9/13 9/80 Aggregate under floor slabs, as called for on the drawings, shall meet the following specifications and be compacted to 90 percent of the maximum den- sity. Sieve Size Percentage Passing Sieve 1" 100 3/4" 90 -100 No. 4 0- 10 Backfill material shall be placed in horizontal, uniform layers not exceeding eight inches (8 ") in thickness before compaction, and shall be brought up uniformly on all sides of the structure or facility. Each layer of backfill shall be compact- ed to a relative compaction of not less than 90 percent. Consolidation of structure backfill by ponding and jetting will be permitted when as determined by the Engineer, the backfill material is of such charac- ter that it will be self- draining when compacted and that foundation materials will not soften or be otherwise damaged by the applied water, and no damage to the structure from hydrostatic pressure will result. When ponding and jetting is permit- ted, material for use as structure backfill shall be placed and compacted in layers not exceeding four feet (4') in thickness. The work shall be performed without damage to the structure or soft- ening of the embankment and in such a manner that excess water will not be impounded. Ponding and jetting methods. shall be supplemented by the use of vibratory or other consolidation equipment when necessary to obtain the required consolidation. Backfill material shall be native material provided that no material larger than three inches (3 ") in greatest dimension shall be used. 02 -15 EARTBFILL CONSTRUCTION 02 -15.1 General Earth' fill construction shall consist of construct- ing embankments, including the preparation of the areas upon which they are to be placed; buttress fills, dikes; the placing and compacting of approv- ed material within areas where unsuitable material in holes, pits and other depressions. 02 -10/13 9/80 Areas over which fills are to be placed shall be cleared of vegetation, scarified and then wetted and rolled prior to placing fill materials. When fills are to be placed over existing surface im- provements which are to remain in place, such clearing.and scarifying will not be required. When fill is to be made and compacted on hillsides or where new fill is to be compacted against exist- ing fill or where embankment is built one -half width at a time, the slopes or original hillsides and old or new fills shall be benched a minimum of four feet (4') horizontally as the fill is placed. A new bench shall be started where the vertical cut for the next lower bench intersects the existing ground. Material thus cut out shall be recompacted along with the new embankment material at the Contrac- tor's expense. • Clods or hard lumps of earth of six inches (6 ") in greatest dimension shall be broken up before com- pacting the material in embankment, with the fol- lowing exception: When the fill material contains large rocks, boul- ders, or hard lumps (such as hardpan or cemented gravel which cannot be broken readily) over twelve inches (12 ") in greatest dimension, such materials may be incorporated in the fill only when authoriz- ed by the Engineer with respect to the acceptabil- ity of the material, the location and depth of its placement in the fill, and the method to be used. Embankments shall not be constructed when material is frozen or a blanket of snow prevents proper com- paction. 02 -15.2 Compacting Fill shall be constructed in compacted layers of uniform thickness and each layer shall be compacted in accordance with the requirements herein speci- fied with the following exception: Where fills are to be constructed across low, swam- py ground which will not support the weight of hauling equipment, the lower part of the embankment may be constructed by dumping successive loads in a 02 -11/13 9/80 uniformly distributed layer of a thickness not greater than that necessary to support the equip- ment while placing subsequent layers. The remain- der of the embankment shall be constructed in lay- ers and compacted as specified. The construction of dikes, the placing and compact- ing of approved material where unsuitable material has been removed, and the filling of holes, pits and other depressions,, shall conform to all of the requirements specified herein for compacting fills. Trenches, holes, depressions and pits outside of areas where fills are to be constructed shall be graded to provide a presentable and well- drained area. Embankments shall be constructed so that each layer shall have a cross fall of at least two percent (2%) but no more than five percent (5%). The loose thickness of each lift of fill material shall not exceed that which will provide the speci- fied relative compaction through the full depth of the lift by the specific compaction equipment being utilized. Each lift shall be compacted in accor- dance with the following requirements to a relative compaction of not less than 90% of the maximum dry density as determined by ASTM D -698 with a moisture content of not less than 2% dry nor more than 3% wet of optimum moisture content. The interstices around the rock in each layer shall be filled with earth or other fine material and ' compacted. Broken portland cement concrete and bituminous type pavement obtained from the project excavations will be permitted in the fill with the following limitations: 1. The maximum dimension of any piece used shall be six inches. 2. Pieces larger than four inches (4 ") shall not be placed within twelve inches (12 ") of any structure. 3. Pieces larger than three inches (3 ") shall not be placed within twelve inches (12 ") of the finished surface. 4. "Nesting" of pieces will not be permitted. At locations where it would be impractical to use mobil power compacting equipment, fill layers shall be compacted to the specified requirements by any approved method that will obtain the specified re- lative compaction. 02 -12/13 9/80 At the time of compaction, the moisture content of fill material shall be such that the specified rela- tive compaction will be obtained and the fill will be firm, hard and unyielding. Fill material which contains excessive moisture shall not be compacted until the material is dry enough to obtain the re- quired relative compaction. Full compensation for any additional work involved in drying fill material to the required moisture content shall be considered as included in the contract price paid and no addi- tional compensation will be allowed therefor. 02 - MEASUREMENT OF PAYMENT No separate payment for work performed under this Item. Include cost of same in Contract prices bid for item of which this work is a component part. 02 -13/13 9/80 SECTION 03 - CONCRETE 03 - GENERAL Concrete consisting of portland cement, concrete ag- gregate, sand and water will be designated by a sym- bol consisting of a number, a letter and a number.

The cement hopper shall be attached to a separate scale for individual weighing. 03 -3/27 3/81 1 m : 03 -08 MIXING I Machine mixing will be required in all cases other than those in which it would obviously prove to be ' impractical, in which event hand mixing will be per- mitted. Mixing shall be commenced as soon as possi- ble after the cement is placed in contact with the I aggregates, but in no event shall the intervening period exceed 30 minutes. ' All concrete mixers shall be of such design and con- struction and so operated as to provide a thoroughly and properly mixed concrete in which the ingredients are uniformly distributed. Mixers shall be main- , tained in proper and serviceable working condition and any part or portion thereof that is out of or- der, or becomes worn to such extent as to detrimen- tally affect the quality of mixing, shall be prompt- ly repaired or replaced. I 03 -09 CONCRETE CONSISTENCY The amount of water added at the mixer shall be re- gulated to take into account the free water in the ' aggregates. Free water is defined as the total water minus the water absorbed by the aggregate in a saturated surface -dry condition. 1 The amount of water used in the mixture shall not exceed the minimum amount necessary to permit prac- I tical placement and consolidation of the concrete, and unless otherwise authorized by the Engineer, shall be that required to produce concrete with a 1 slump within the range shown as nominal in the fol- lowing table: 1 Type of Work Nominal Slump Maximum Slump (inches) (inches) Concrete Pavement 0 -2 3 I Non - reinforced Concrete 0 -3 4 Reinforced Concrete Structures ' Heavy Sections 0 -3 5 Thin Sections & Columns 0 -4 6 Concrete Placed under Water 6 -8 9 1 03 -5/27 3/81 1 The concrete used in the work shall riot have a slump greater than that shown as maximum above, nor a free water content greater than 312 pounds per cubic yard of concrete. When adverse or difficult conditions affect the placement of concrete, the Engineer may authorize a greater slump to be used, provided both the water and cement are increased. Water shall be added at a ratio not to exceed 30 pounds per sack of added cement per cubic yard of concrete, and such addi- tional water and cement shall be at the Contractor's expense. The consistency of concrete shall be determined in accordance with ASTM C -143. If slump tests of individual samples taken at appro- ximately the 1/4 and 3/4 points of the discharge differ by more than two inches (2 "), the mixer will not be acceptable for further use until the condi- tion is corrected. 03 - 10 TRANSIT MIXERS The type, capacity, and manner of operation of the mixing and transporting equipment for ready -mix con- crete shall conform to the current ASTM C -94 stan- dard; "Standards for Operation of Truck Mixers and Agitators of the National Ready -Mixed Concrete Asso- ciation" and the "Truck Mixer and Agitators Stan- dards of the Truck Mixer Manufacturers Bureau ". Transit mix concrete trucks shall be equipped with an automatic device for recording the number of revolutions of the drum during the mixing period. Each mixer and agitator shall have attached thereto in a prominent place, a metal plate or plates, in- stalled by the manufacturer on which is plainly marked the capacity of the drum in terms of the volume of mixed concrete and the speed of rotation for the agitating and mixing speeds of the mixing drum or blades. Each mixer shall have an identification number painted on the truck in such a location that it can be easily read from the batching platform. The total volume of materials introduced into the mixer shall not exceed the manufacturer's guaranteed mixing capacity. If the concrete so mixed does not 03 -6/27 3/81 meet the uniformity requirements of this subsection, the amount of materials charged into the mixer shall be reduced. The drum of the mixer shall be completely emptied of any previously mixed load. The proper proportions of aggregate, cement, and water for each load of concrete shall be placed in the mixer and shall be mixed therein for not less than 70 nor more than 100 revolutions of the drum or blades at the speed de- signated by the manufacturer of the equipment as mixing speed. Additional revolutions of the drum shall be at the speed designated by the manufacturer of the equipment as agitating speed. The revolving of the drum shall be continuous until the concrete is completely emptied from the drum. When concrete is being placed for concrete struc- tures, all wash water shall be emptied from the mix- er before any portion of the succeeding load is placed therein. For all other work, the mixer shall be empty or may carry 10 gallons of water in the drum. Adequate control of ready -mixed concrete will normally require that additional water be added and mixed into the batch at the point of discharge. Water so added shall be mixed into the load for a minimum mixing time of three (3) minutes. Water shall not be added to the load during transit. The total elapsed time between the addition of water at the batch plant and discharging the completed mix shall not exceed 90 minutes. Under conditions con- tributing to quick setting, the total elapse time permitted may be reduced by the Engineer. The Engineer shall be provided with a legible certi- fied weighmaster's certificate which shall contain the following information: Name of vendor Name of contractor Number of cubic yards in the load Actual weights of cement and of each size of aggregate Amount of water added at the plant Amount of water in the aggregate Brand and type of cement Brand and amount of admixture Time and date of batching 03 -7/27 3/81 Space shall be provided on the certificate so that amount of water added on the job may be indicated. 03 -11 HAND MIXING Hand mixed concrete shall be mixed on a water -tight platform or in a mortar box in batches not to exceed 1/3 cubic yard each.

When the subgrade is in dry earth, it shall be tho- roughly dampened with water to ensure that no mois- ture will be absorbed from the fresh concrete. 03 -15.3 Forms When the design details for the project provide for the construction of filter or drain material con- sisting of gravel (or combination of gravel and sand), which material will be subgrade for concrete, the placing of steel reinforcement and placement of concrete shall follow the installation of the filter or drain material as closely as practical. The fil- ter or drain material shall be kept de- watered to the extent necessary to prevent any portion of con- crete materials being deposited in water. When the concrete is to be deposited on rock, the rock shall be fully uncovered, cleaned, and its sur- face shall be. removed to a depth sufficient to ex- pose sound rock. Bedrock shall be roughly leveled - off or cut to approximately horizontal and vertical steps. Seams in the rock shall be grouted under pressure or otherwise treated as the Engineer may direct. Forms shall be of suitable material and of a type, size, shape, quality, and strength to ensure con- struction as designed. The forms shall be true to line and grade, mortar tight, and sufficiently rigid to resist deflection during placing of the concrete. The responsibility for their adequacy shall rest with the Contractor. All dirt, chips, sawdust, nails and other foreign matter shall be completely removed from forms before any concrete is deposited therein. The surfaces of forms shall be smooth and free from irregularities, dents, sags and holes that would deface the finished surfaces. Forms previous- ly used shall be thoroughly cleaned of all dirt, mortar and foreign matter before being re -used. 03 -14/27 3/81 1 Before concrete is placed in forms, all inside 1 surfaces of the forms shall be thoroughly treated with releasing agent as specified herein. Care shall be exercised that no releasing agent is deposited on previously placed concrete. Forms for all surfaces that will not be completely I enclosed or hidden below the permanent surface of the ground shall be made of surfaced lumber, or material which will provide a surface at least equal I to surfaced lumber or plywood. Any lumber or mate- rial which becomes badly checked or warped, prior to placing concrete, shall not be used. I Forms for all exposed surfaces shall be constructed of plywood or an approved equal. Plywood for forms shall be Exterior Type, of the grade "Concrete -Form I Exterior ", conforming to the specifications of the U. S.

I Plywood shall be placed with the grain of the outer plies in the direction of the longest span. Where 1 plywood is attached directly to the studs or joists, the panels shall be not less than 5/8 inch thick, and the studs or joists shall be spaced not more I than 12 inches, center -to- center. Plywood less than 5/8 inch thick, otherwise conforming to the require- ments specified herein, may be used with a contin- uous backing of 3/4 inch sheeting. All form panels shall be placed in a neat symmetrical pattern with the horizontal joists level and continuous. All I joints shall be filled with an approved quick -set- ting compound and finished flush with the interior of the form. Wooden forms for copings and curbs shall have a thickness of not less than 1 -5/8 inches and a width of not less than the full depth of coping or curb. 1 Unless otherwise shown on the plans, all sharp edges shall be chamfered with 3/4 inch by 3/4 inch trian- gular fillets. Forms for curved surfaces shall be so constructed and placed that the finished surface will not deviate from the arc of the curve by more than the tolerance shown on the Plans. 1 03 -15/27 3/81 1 Forms shall be so constructed that portions, where finishing is required, may be removed without dis- turbing portions of forms to remain in place. Forms for girders and slabs shall be cambered as may be required by the Engineer. Forms shall, as far as practicable, be so construct- ed that the form marks will conform to the general line of the structure. Form clamps or bolts, approved by the Engineer, shall be used to fasten forms. The use of twisted wire loop ties to hold forms in position will not be permitted, nor shall wooden spreaders be used unless authorized by the Engineer. Clamps or bolts shall be of sufficient strength and number to prevent spreading of the forms. They shall be the break -off type so that they can be entirely removed or cut back 1 inch below the finished surface of the con- crete. All forms for outside surfaces shall be con- structed with stiff wales at right angles to the studs, and all form clamps or bolts shall extend through and fasten such wales. Form work shall be approved prior to placement of concrete in the form. 03 -15.4 Removal of Forms The periods of time for form removal set forth here- in are permissive only and subject to the Contractor assuming all risks that may be involved. The time periods are minimum with no allowance therein for external loads. At times of low temperature, or other adverse conditions, the Engineer may require the forms to be kept in place for longer periods of time. The time periods are predicated on the use of con- crete to which no admixtures have been added. No forms shall be removed until approval of Engineer is obtained. Forms shall be stripped after the re- quired time and projecting wire snapped off. Remov- al shall not proceed faster than the required fin- ishing procedure can be completed. Vertical forms shall not be disturbed for at least twenty -four (24) hours after last concrete in walls is placed, except as authorized by the Engineer. 03 -16/27 3/81 Forms shall remain in place a minimum of twenty -four (24) hours and be removed only after Engineer's approval. 03 - 15.5 Falsework All falsework shall be designed and constructed to provide the necessary rigidity and to support the loads. Falsework for the support of a superstruc- ture shall be designed to support the loads that would be imposed if the entire superstructure were placed at one time. All falsework, staging, walkways, forms, ladders, cofferdams, and similar accessories shall equal or exceed the minimum requirements of the State Divi- sion of Industrial Safety. Compliance with such requirements shall not relieve the Contractor from full responsibility for the adequacy of safety mea- sures. 03 - 15.6 Placing Reinforcement Before placing reinforcing steel, the Contractor shall submit a reinforcing steel placing plan for approval of the Engineer. Reinforcing bars shall be accurately placed as shown on the plans and shall be firmly and securely held in position in accordance with Concrete Reinforcing Steel Institute "Recommended Practice for Placing Reinforcing Bars ", and by using concrete or metal chairs, spacers, metal hangers, supporting wires and other approved devices of sufficient strength to resist crushing under full load. Metal chairs which extend to the surface of the concrete (except where shown on the plans) and wooden supports, shall not be used. Placing bars on layers of fresh concrete as the work progresses and adjusting bars during the placing of concrete will not be permitted. Before placing in the forms, all reinforcing steel shall be cleaned thoroughly of mortar, oil, dirt, loose mill scale, loose or thick rust, and coatings of any character that would destroy or reduce the bond. No concrete shall be deposited until the placing of the rein- forcing steel has been inspected and approved. 03 -17/27 3/81 03 -15.7 Splicing Splices of bars shall be made only where shown on the plans or as approved by the Engineer. Where bars are spliced, they shall be lapped at least 36 diameters, unless otherwise shown on the plans. Splicing shall be accomplished by placing the bars in contact with each other and wiring them togeth- er. Welding of reinforcing steel will not be permitted unless specifically authorized by the Engineer. 03 -15.8 Bending Reinforcement Bends and hooks in bars shall be made in the manner prescribed in the "Manual of Standard Practice" of the American Concrete Institute. Bars shall not be bent or straightened in a manner which will injure the material.

If the pipe laying crew cannot place the pipe in the trench without getting earth into it, the Engineer may require that, before low- ering the pipe into the trench, a heavy, tightly 07 -9/14 3/81 woven canvas bag of suitable size shall be placed over each end and left there until the connection is to be made to the adjacent pipe. During laying operations, no debris, tools, clothing, or other materials shall be placed in the pipe. At times when pipelaying is not in progress, the open ends of pipe shall be closed by a watertight plug or other • means approved by the Engineer. Pipe shall be laid with the bell ends or coupling ends facing in the direction of the laying unless directed otherwise by the Engineer or specifically indicated on the Drawings. All pipe shall be carefully placed and supported at the proper line and grade, and shall be sloped to permit drainage. Minor adjustment may be necessary• to avoid architectural and structural features. Major relocations shall be approved by the Engi- neer. Minimum earth cover shall be 30 inches, un- less otherwise shown on the Drawings. Sufficient screw unions, flanges joints, or flex- ible couplings shall be used to allow the conven- ient removal of any run of pipe without removing adjacent runs or equipment. Where practicable, make -up joints have been indicated on the Drawings; however, omission of these joints from the Drawings does not excuse the Contractor from their installa- tion. • Whenever a pipe larger than 3 inches in dia- meter is cast or grouted in place and passes from concrete to earth, a flexible coupling must be used on the earth side. Bare metal pipe passing from concrete to earth shall be wrapped with Scotch Wrap 50 for 3 inches each side of the concrete face on the earth side.

Both bell and spigot shall be clean before the joint is made, and care shall be taken that nothing but the joint- making material enters the joint. If water is encountered in the trench, it shall be kept below the bottom of the bell of the pipe. Should the water, through neglect or otherwise, rise in the trench before the jointing operation is completed, the anular space in all pipe so affected shall be freed of all water and foreign matter and thoroughly cleaned before completing the jointing operation. When pipe laying is not in progress, the forward end of the pipe shall be kept effectively closed with an approved temporary barricade. 07 -06 CLEANING, TESTING AND DISINFECTION 07 -06.1 General Pressure and gravity lines shall foreign matter and tested in the the satisfaction of the Engineer corrected or, in the case of the be brought within the allowable tractor's expense.

I 10 -05 APPLICATION OF PAINT I On metal surfaces, the painter shall apply each coat of paint at the rate specified by the manufac- turer to achieve the minimum dry mil thickness re- quired. If material has thickened or must be di- luted for application by spray gun, the coating 1 10 - 4/6 9/80 1 ,1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 . 1 shall be built up on the same film thickness achieved with undiluted material. In effect this means one (1) gallon of paint as originally fur- nished by the manufacturer must not cover a greater square foot area when applied by spray gun than when applied unthinned by brush. Deficiencies in film thickness shall be corrected by the applica tion of an additional coat of paint. On concrete, application rates will vary according to surface texture; however, in no case shall the manufactur- er's stated coverage rate be exceeded. On porous surfaces, it shall be the painter's responsibility to achieve a protective and decorative finish either by decreasing the coverage rate or by apply- ing additional coats of paint. Apply paint only when temperature and atmospheric conditions are favorable to drying, and are such to preclude condensation on surfaces to receive paint. Do not apply paint when either surface•or ambient • temperatures are less than 50 degrees Fahrenheit, or when temperature drop of 20 degrees, or below 50 degrees Fahrenheit is forecast. Do not apply paint to surfaces upon which there is frost or moisture, nor during misty or rainy weather unless specific approval is given. Do not apply finish field painting to machinery, equipment, or piping until operational testing has been completed. The Contractor shall submit to the Engineer, imme- diately upon completion of the job, certification from the manufacturer indicating that the quantity of each coating purchased was sufficient to proper- ly coat all surfaces. Such certification shall make reference to square footage figures provided to the manufacturer by the Contractor. Drying time shall be construed to mean "under nor- mal conditions ". Where conditions are other than normal because of the weather or because painting must be done on confined spaces, longer drying times will be necessary. Additional coats of paint shall not be applied, nor shall units be returned to service until paints are thoroughly dry. After installation of machinery and electrical equipment, check base coats carefully and retouch all damaged surface areas. Do not paint name- plates, serial number bases, chrome or bronze trim, or any rotating parts. Clean off any excess paint 10 -5/6 9/80 that impairs convenient removal of covers on gaug- es, instrumentation, or other equipment fitted with doors or covers. Thinners: Where thinning is necessary, only the products of the manufacturer furnishing the paint, and for the particular purpose, shall be allowed, , and all such thinning shall be done strictly in accordance with the manufacturer's instructions, as well as with the full knowledge and approval of the Engineer. Colors: Unless specified on the Plans or elsewhere in these Specifications, color of the painted sur- faces shall be selected by the Engineer. Upon completion of the protective coating and painting, the Contractor shall remove all surplus materials and rubbish and remove all spattered material from surfaces where its presence is objec- tionable. All coated or painted surfaces shall be free from abrasion or other blemish when the pro- ject Is ready for final acceptance by the Engi- neer. 10 -06 WORKMANSHIP All work shall be done by skilled craftsmen who are qualified to perform the required work and shall be done in a manner comparable to the best standards of practice found in the trade. All materials shall be evenly applied so as to be free from sags, runs, crawls, wrinkles, holidays, or any other ap- plication defects. All coats shall be of the pro- per consistency and properly brushed out so as to show the minimum of brush marks. All coats shall be thoroughly dry before the succeeding coat is ap- plied. All coats that are intended to hide shall be given another coat if the coating does not pro- perly hide the undercoat. 10 -07 PROTECTION OF WORK Full protection shall be given other work from damage by use of clean drop cloths during the time that the paint is being applied. 10 -08 MEASUREMENT AND PAYMENT No separate payment for work performed under this item.

The geotechnical investigation reported herein is an analysis of the subsurface materials and conditions at the proposed site of a Water Treatment Plant. The site is located just west of Interstate Highway 35 near Round Rock, Texas. It is understood that the plant facilities will consist of a dual clarifier and control building, two earthen holding tanks, and a 100 -ft- diameter, 16 -ft -high, steel water storage tank. This investigation was conducted in general accordance with our proposal letter dated December 12, 1980 and verbally author- ized by Mr. Haynie on December 16, 1980. Scope of Investigation. The objectives of this investigation have been to develop information on soil and foundation conditions at the site and to use this information in developing criteria for use in the foundation design process. To accomplish these objectives the various stages of the investigation were conducted as follows: 1. Subsurface core borings were drilled in order to (a) explore subsurface stratigraphy at the site, (b) obtain samples for laboratory testing, (c) investigate in situ rock characteristics through THD cone penetrometer tests, and (d) investigate groundwater conditions present at the site. 1 GEOTECHNICAL ENGINEERING DIVISION TRINITY ENGINEERING TESTING CORPORATION 2. Samples of subsurface materials from the core borings were analyzed in the laboratory by. (a) visual examination and classification, (b) Atterberg limits tests, (c) minus 200 -mesh sieve tests, (d) unit dry weight and moisture content tests, and (e) unconfined compression tests. 3. An engineering analysis was then made using the informa- tion obtained from the subsurface exploration and labora- tory investigation to develop recommendations to guide foundation design and construction. The various phases of this study, as mentioned above, are presented in subsequent sections of this report. GEOTECHNICAL ENGINEERING DIVISION FIELD INVESTIGATION • TRINITY ENGINEERING TESTING CORPORATION Subsurface conditions and stratigraphy at the proposed Water Treatment Plant Site were explored by fourteen borings drilled at the locations shown on Plate I in the Appendix. The borings were advanced to depths ranging from 10.0 to 15.0 feet below the ground surface. The various depths to which each boring extended and the types of subsurface mate- rials encountered are noted an the attached Logs of Borings. The borings were drilled with the aid of a truck - mounted drilling rig. Undisturbed or representative samples of the cohesive soils were ob- tained by hydraulically pushing a 3 -in. diameter thin- walled tube sam- pler into the soil. Thereafter, samples of the primary formation were obtained by continuous rock coring with an NX -size double -tube core barrel equipped with an insert bit. All of the samples obtained in the borings were visually classified and logged in the field during the investigation. After the samples had been examined and classified, they were sealed in appropriate packaging for shipment to our labora- tory for further study. Existing in situ conditions of the subsurface materials were also ex- plored by Texas Highway Department (THD) cone penetration tests per- formed at periodic intervals while the boreholes were being advanced. The THD cone penetration test consists of a measurement of the resist- ance to penetration of a 3 -in. diameter steel cone that is driven with a 170 -1b weight dropped approximately 24 in. The amount of penetration GEOTECHNICAL ENGINEERING DIVISION of the cone after an application of 100 blows is recorded on the attached Logs of Borings. The borings were advanced to depths ranging from 0.0 to 3.0 feet below the ground Surface prior to using drilling fluid. Groundwater obser- vations below these depths were inhibited due to the use of drilling fluid. Results of the observations to investigate groundwater condi- tions at the site are shown by the notes on the attached Logs of Borings. 4 TRINITY ENGINEERING TESTING CORPORATION GEOTECHNICAL ENGINEERING DIVISION TRINITY ENGINEERING TESTING CORPORATION LABORATORY INVESTIGATION All samples and cores of subsurface materials recovered from the bor- ings were examined and logged in the laboratory by a soil technician. The laboratory testing program was then designed to evaluate the per- tinent physical properties of the foundation soils. Due to the nature of the proposed project, emphasis was directed toward evaluation of the compressive strength and shrink /swell potential of the underlying strata. Atterberg limits tests and minus 200 -mesh sieve tests were performed to estimate the shrink /swell potenital of the soil and to aid in soil classification. Laboratory classifications of the subsurface mate- rials are based upon the "Unified Soil Classification System" as ex- plained on the attached Key to Classification used on Logs. Results of the Atterberg limits tests, minus 200 - mesh sieve tests, natural moisture content and soil classifications are presented on attached Plate II. Unconfined compression tests were performed on selected specimens in order to determine the compressive strength of the soil and rock strata. Water content and unit dry weight determinations were also • made for soil specimens subjected to unconfined compression tests. The results of the strength tests are tabulated on Plate III. The type and number of tests performed in the laboratory for this in- vestigation are presented on the following page: 5 GCOTECHNICAL ENGINEERING DIVISION TRINITY ENGINEERING TESTING CORPORATION Type of Tests Number of Tests Unconfined Compression 12 Atterberg Limits 4 Percent Passing 200 -Mesh Sieve 4 Moisture Content 8 Unit Weight 4 6 GEOTECHNICAL ENGINEERING DIVISION TRINITY ENGINEERING TESTING CORPORATION SITE CONDITIONS Site Geology. According to information developed by the Bureau of Economic Geology at the University of Texas at Austin, the primary geologic formation at this site is the Edwards formation. This forma- tion is of the Lower Cretaceous Geologic Age and consists mainly of limestone. In the unweathered state, the Edwards formation consists of gray limestone having honeycomb seams and layers or solution cavi- ties. Weathering of the primary gray limestone creates a tan lime- stone stratum having hard limestone layers and interbedded soil - like layers or pockets. Severe weathering and the addition of or- ganic matter results in an upper dark brown soil layer that can be classified at this site, as a high plasticity clay. Subsurface Stratigraphy. In general, the stratigraphy encountered in the borings is fairly uniform having approximately 0.5 to 4.0 ft of dark brown high plasticity clay overlying a weathered limestone or massive limestone of the Edwards formation. As indicated in Boring Nos. 1 through 6 and 11, a honeycomb structure exists in the limestone formation.. This honeycomb structure varies in depth from 7.8 to 15.0 ft below the ground surface but is generally encountered at the 10 ft depth. The only peculiarities from the general stratification de- scribed above was found to occur in Boring Nos. 8 and 11 where a black chert and sand and gravel layer was encountered, respectively. The depth intervals at which the chert and granular layers were encountered are 11.8 to 12.0 ft and 5.0 to 6.0 ft, respectively. GEOTECNNICAL ENGINEERING DIVISION FOUNDATION DESIGN CRITERIA TRINITY ENGINEERING TESTING CORPORATION General. This geotechnicai investigation encompasses several proposed structures including a plant and control building, two earthen holding tanks, and a water storage tank. The subsurface conditions are essen- tially similar at each structure location. However, each building or problem area will be discussed separately within this report in order to cover particular foundation systems or problems associated with the individual structures. Expansive Characteristics. The surficial soils at this site are pri- marily very stiff, high plasticity clays. As indicated by the Atter- berg limits tests, the shrink /swell or expansive potential of the clays is relatively high with plasticity indexes ranging from 37 to 47. In addition, using the Potential Vertical Rise Method developed by McDowell and a worst case condition of 4 ft of expansive material, a potential vertical movement of 1.75 in. was computed. This potential movement is considered to be moderately high and could be of significance with respect to structures supported on shallow foundations. Therefore, it is suggested that consideration be given to eliminating the poten- tial detrimental movements where shallow foundations are proposed by removal and replacement of the expansive clay stratum with a select, non - expansive fill material. Select Fill Material. Fill material used within the building areas should be a low plasticity material that has been properly compacted 8 GEOTECHNICAL ENGINEERING DIVISION TRINITY ENGINEERING TESTING CORPORATION to prevent settlements of loosely placed material and to insure ade- quate load.bearing characteristics. The fill material should be com- pacted to at least 95 percent of the maximum density as determined by the procedure of ASTM D698 in lifts not to exceed 6 - in. compacted thickness. The select material should have primarily granular characteristics with a PI less than 15 and not more than 40 percent passing the No. 200 sieve. Crushed limestone products are locally available and may be considered for use at this site. Plant and Control Building, Boring Nos. 1 - 6. At present, it is planned to construct within the Plant Section of the proposed building two conical shaped clarifiers and filters that will extend to a depth of about 10 ft below the existing ground surface. Accordingly, the loads imposed by the clarifiers and filters will be transferred to the supporting tan limestone stratum through concrete mats. These mats should be designed in accordance with an allowable bearing pres- sure of 20,000 lb /sq ft. The given design value includes an applied safety factor of at least 2.0 and assumes that the supporting lime- stone formation is competent and continuous. Although no large cavities were encountered in the borings drilled for this investigation, the presence of honeycomb layers in the bor- ings indicates the possibility of cavities. As a result, it is sug- gested that the competency of the limestone directly beneath the proposed foundation be investigated by drilling 2- in- diaheter 9 GEOTECHNICAL ENGINEERING OIVISION TRINITY ENGINEERING TESTING CORPORATION test holes, or a size hole equivalent to those produced by standard shot - hole drilling equipment. As indicated on Plate IV, measurements of the hole diameter should be made with calipers or a probe. The drilling should be performed at a grid spacing sufficient to assure the adequacy of the foundation strata and the hole depth should be equal to 5 ft or twice the foundation width, whichever is less. If substantial cavities larger than a few inches in diameter or highly porous rock are encountered during the investigation, then placement of lean concrete or slush grout in the voids may be necessary. The Control Section of the proposed building is assumed to be a rela- tively light structure housing primarily piping, control values, and monotoring equipment. The exterior loads of the building may be sup- ported by a perimeter strip -type foundation if the strip is founded at a depth of at 1.0 ft into the tan weathered limestone and designed in accordance with an allowable bearing pressure of 6,500 lb /sq ft. The interior slab of the building may be supported by select well com- pacted fill (see above section) if designed using an allowable bearing pressure of 2,500 lb /sq ft. Should loads imposed on the interior slab exceed the bearing capacity of the fill material, consideration may be given to the use of isolated shallow footings for support of heavily - loaded slab sections. The footings should be founded at a depth of 5 ft below the ground surface and designed for a maximum bearing pressure of 10,000 lb/so ft. 10 GEOTECHNICAL ENGINEERING DIVISION TRINITY ENGINEERING TESTING CORPORATION It is understood that.a deep splitter box will be used to channel plumbing from the clarifiers and filters into the control building. Presently, it is planned to place the base of the splitter box at a depth of 10 ft below existing ground surface. At this depth, the box may be designed in accordance with an allowable bearing pressure of 20,000 lb/so ft. Earthen Holding Tanks, Boring Nos. 7 -10. The two holding tanks, cen- trally located at the proposed site, are scheduled to be constructed such that the tank bases will extend into the primary tan limestone stratum. Accordingly, consideration may need to be given to lining the bases and the sides in order to prevent migration of impounded water. The surficial dark brown clay existing at the site will pro- vide an excellent liner material and may be used to construct the sides of the tanks. The material should be compacted at or near opti- mum moisture content, to a density of at least 95 percent of the maxi- mum dry density as determined by ASTM D 698 and in lifts not to ex- ceed 6 in. compacted thickness. The embankment slopes may be con- structed at a slope of 1- vertical to 3- horizontal but, in order to prevent erosion, consideration may be given to using flatter slopes. Alternatively, some type of slope proctection, i.e. sod, asphalt or bituminous surfacing, or synthetic liners, may be used. Water Storage Tank, Boring Nos. 11 -12A. The 100 -ft- diameter by 16- ft -high steel water tank can be supported by either of two foundation alternatives. The first alternative would include the use of a 11 GEOTECHNICAL ENGINEERING DIVISION TRINITY ENGINEERING TESTING CORPORATION reinforced concrete ringwall supporting the tank shell while the second would use a steel ring founded on select fill material. A schematic cross- section of both of these foundation alternatives is illustrated on Plate V. For either scheme, the high plasticity sur- ficial clay layers existing at the site should be removed from the foundation area and a granular, low plasticity fill should be placed beneath the bottom of the tank. • This fill material should be similar to that described previously and should be placed in accordance with the associated compaction recommendations. It is further suggested that the top 6 in. of fill be oil saturated during construction in order to reduce potential corrosive action on the bottom of the tank. If a reinforced concrete ringwall is used to support the tank shell, the ringwall should be founded approximately 6 in. into the tan weath- ered limestone and designed in accordance with an allowable bearing pressure of 6,500 lb /sq ft. The width of the ringwall should be pro- portioned so that the pressure at the base of the ringwall does not exceed the soil pressure at the same level beneath the interior of the tank due to the weight of the stored water and the containment structure itself. For the steel ring and compacted fill scheme, a compacted supporting base'ring of fill should be used instead of a concrete ringwall. The material used to construct the base ring should be crushed limestone meeting Texas Highway Department Item 248, type A, grade 2 or better 12 GEOTECHNICAL ENGINEERING DIVISION requirements. A safe allowable load intensity of 3,500 lb /sq ft may be used for the crushed limestone provided that the material is com- pacted to a minimum of 95 percent of ASTM D 698, method D maximum density with lifts not to exceed 6 in. compacted thickness. Bearing plates maybe required in order to reduce the applied bearing'stresses at the tank -fill interface. In addition, the select fill should also extend inward and outward a minimum of 2.0 ft from the tank edge and be constructed with interior and exterior slopes of approximately 1- vertical to 2- horizontal. This will help to achieve proper drainage of surface water and will also help to prevent undermining of the foundation and infiltration of water.
