Consider a resolution authorizing the Mayor to execute a contract with Horseshoe Construction, Inc for the 2001 Wastewater Collection System Rehabilitation Project Horseshoe Construction, Inc. submitted a bid proposal of $1,142,600.00 for this project. Resource: Jim Nuse, Director of Public Works Don Rundell, Chief Utility Engineer History: RJN Group, Inc. was retained by the City to conduct a multi -year Inflow and Infiltration (1 &I) Reduction Plan. Phase I was completed in August 1998, which included flow monitoring, manhole and wastewater line inspections. Phase 11 was the Evaluation Study for Basins BC21Z, 0C24Z, and CC35Z, which included intensive surveying, testing and inspection of the wastewater collection system within these three basins. This general scope of work under this contract, which is based on RJN's recommendations developed under the Phase II Evaluation Study, is for the replacement of 10,800 linear feet of wastewater lines, rehabilitation of 305 manholes, and other minor system repairs within these three basins. We received four (4) bids with a range from $1,142,600.00 to $1,670,587.00. Horseshoe Construction, Inc. had the low bid of $1,142,600.00. Funding: Cost: $1,142,600.00 Source of funds: Wastewater Water Utility Fund (F260) Outside Resources: Horseshoe Construction, Inc. Impact/Benefit: Reducing the I &I entering our wastewater system will reduce potential ground contamination and reduce the City's Wastewater Treatment Cost to the LCRA and BRA. Public Comment: N/A Sponsor: N/A Most importantly we are required under TNRCC, Chapter 213 — Edwards Aquifer Rules to inspect, test and make necessary repairs to our wastewater collection system every five years.

In the event the Contractor fails or refuses to clean and remove surplus materials and debris as above provided, the Owner or the Engineer may do so, or cause same to be done, at the Contractor's expense, and the reasonable cost thereof shall be deducted from the final payment. 3.20 Guarantee Against Defective Work The Contractor warrants the materials and workmanship and that the work is in conformance with the plans and specifications included in this contract for a period of one year from the date of acceptance of the project. Said warranty binds the Contractor to correct any work that does not conform with such plans and specifications or any defects in workmanship or materials furnished under this contract which may be discovered within the said one year period. The Contractor shall at his own expense correct such defect within thirty (30) days after receiving written notice of such defect from the Owner or the Engineer by repairing same to the condition called for in the Contract Documents and plans and specifications. Should the Contractor fail or refuse to repair such defect within the said thirty (30) day period or to provide acceptable assurances that such repair work will be completed within a reasonable time thereafter, the Owner may repair or cause to be repaired any such defect at the Contractor's expense. - 3.21 Testing of Materials Unless otherwise specified, testing of all materials to be incorporated into the project will be as directed by the Engineer at the expense of the Owner. All retesting for work rejected on the basis of test results will be at the expense of the Contractor and the extent of the retesting gencond.mstispec master GC -21 shall be determined by the Engineer. The Engineer may require additional testing for failing tests and may require two (2) passing retests before acceptance will be made by the Owner. The testing laboratory will be designated by the Owner. All materials to be incorporated into the project must meet the requirements of these specifications. For manufactured materials such as reinforcing steel, expansion joint materials, concrete pipe, cement, miscellaneous steel, cast iron materials, etc., the Contractor will be required to furnish a manufacturer's certificate stating that the material meets the requirements specified for this project. 3.22 Wage Rates (Information From Chapter 2258 Texas Government Code Title 10) 2288.021.

WR1001 July 1997 Applicable wage rates are shown in Section 06 WAGE RATES of the SPECIAL CONDITIONS. 4. Prosecution and Progress 4.01 Time and Order of Completion 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 seasons, in such order of precedence, and in such manner as shall be most conducive to economy of construction; provided, however, that the order and the time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications, and within the time of completion designated in the proposal: provided, also, that when the Owner is having other work done, either by contract or by his own force, the Engineer may direct the time and manner of constructing the work done under this contract, so that conflict will be avoided and the construction of the various works being done for the Owner shall be harmonized. The Contractor shall submit, at such times as may reasonably be requested by the Engineer, schedules which shall show the order in which the Contractor proposes to carry on the Work, with dates at which the Contractor will start the several parts of the work, and estimated dates of completion of the several parts. 4.02 Extension of Time Should the Contractor be delayed in the completion of the work by any act or neglect of the Owner or the Engineer, or of any employee of either, or by other contractors employed by the Owner, or by changes ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoidable cause or causes beyond the Contractor's control, or by any cause which the Engineer shall decide justifies the delay, then an extension of time shall be allowed for completing the work, sufficient to compensate for the delay, the amount of the extension to be determined by the Engineer; provided, however, that the Contractor shall give gencond.mstispec master GC -23 the Engineer prompt notice in writing of the cause of such delay. Adverse weather conditions will not be justification for extension of time on "Calendar Days" contracts. 4.03 Hindrances and Delays No claims shall be made by the Contractor for damages resulting from hindrances or delays from any cause (except where the work is stopped by order of and for the convenience of the Owner) during the progress of any portion of the work embraced in this contract. In case said work shall be stopped by the act of the Owner, then such expense as in the judgment of the Engineer is caused by such stoppage of said work shall be paid by the Owner to the Contractor. 5. Measurement and Payment 5.01 Quantities and Measurements No extra or customary measurements of any kind will be allowed, but the actual measured and/or computed length, area, solid contents, number and weight only shall be considered, unless otherwise specifically provided. 5.02 Estimated Quantities This agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and material furnished. Where payment is based on the unit price method, the Contractor agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contemplated and contained in the proposal; provided, however, that in case the actual quantity of any major item should become as much as twenty percent (20 %) more than, or twenty percent (20 %) less than the estimated or contemplated quantity for such items, then either party to this agreement, upon demand, shall be entitled to revised consideration upon the portion of the work above or below twenty percent (20 %) of the estimated quantity. gencond.mstfspec master GC -24 A "Major Item" shall be construed to be any individual bid item incurred in the proposal that has a total cost equal to or greater that five percent (5 %) of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices. Any revised consideration is to be determined by agreement between the parties, otherwise by the terms of this agreement, as provided under "Extra Work ". 5.03 Price of Work In consideration of the furnishing of all the necessary labor, equipment and material, and the completion of all work by the Contractor, and on the completion of all work and on the delivery of all material embraced in this contract in full conformity with the specifications and stipulations herein contained, the Owner agrees to pay the Contractor the prices set forth in the proposal hereto attached, which has been made a part of this contract. The Contractor hereby agrees to receive such prices in full for furnishing all material and all labor required for the aforesaid work, also 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 agreement. 5.04 Partial Payments On or before the first day of each month, the Contractor shall submit to the Engineer a statement showing the total value of the work performed up to and including the 25th day of the preceding month. The statement shall also include the value of all sound materials delivered on the job site and to be included in the work and all partially completed work whether bid as a lump sum or a unit item which in the opinion of the Engineer is acceptable. The Engineer shall examine and approve or modify and approve such statement. The Owner shall then pay the Contractor on or before the 20th day of the current month the total amount of the approved statement, less five percent (5 %) of the amount thereof, which five percent (5 %) shall be retained until final payment, and further less all previous payments and all further sums that may by retained by the Owner under the terms of this agreement. It is understood, however, that in case the whole work be near to completion and some unexpected and unusual delay occurs due to no fault or neglect on the part of the Contractor, then the Owner may, upon written recommendation of the Engineer, pay a reasonable and equitable portion of the retained percentage to the Contractor; or the Contractor, at the Owner's option, may be relieved of the obligation to fully complete the work and, thereupon, the Contractor shall receive payment of the balance due him under the contract subject only to the conditions stated under "Final Payment ". - 5.05 Use of Completed Portions The Owner shall have the right to take possession of and use any completed or partially completed portions of the work, notwithstanding the time for completing the entire work or such portions may not have expired. Such taking possession and use shall not be deemed an gencond.mst/spec master GC -25 acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost or delays the work, the Contractor shall be entitled to such extra compensation, extension of time, or both, as the Engineer may determine. The Contractor shall notify the Engineer when, in the Contractor's opinion, the contract is "substantially completed" and when so notifying the Engineer, the Contractor shall furnish to the Engineer in writing a detailed list of unfinished work. The Engineer will review the Contractor's list of unfinished work and will add thereto such items as the Contractor has failed to include. The "substantial completion" of the structure or facility shall not excuse the Contractor from performing all of the work undertaken, whether of a minor or major nature, and thereby completing the structure or facility in accordance with the Contract Documents. 5.06 Final Completion and Acceptance Within ten (10) days after the Contractor has given the Engineer written notice that the work has been completed, or substantially completed, the Engineer and the Owner shall inspect the work and within said time, if the work is found to be completed in accordance with the Contact Documents, the Engineer shall issue to the Owner and the Contractor his Certificate of Completion, and thereupon it shall be the duty of the Owner to issue a Certificate of Acceptance to the Contractor or to advise the Contractor in writing of the reason for non- acceptance. 5.07 Final Payment Upon the issuance of the Certificate of Completion, the Engineer shall proceed to make final measurements and prepare final statement for the value of all work performed and materials furnished under the terms of the agreement and shall certify same to the Owner, who shall pay to the Contractor on or before 35th day after the date of the Certificate of Completion, the balance due the Contractor under the terms of this contract; and said payment shall become due in any event upon said performance by the Contractor. Neither the Certificate of Acceptance nor the final payment, nor any provision in the Contract Documents, shall relieve the Contractor of the obligation for fulfillment of any warranty which may be required. 5.08 Payments Withheld The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect- himself from loss on account of: a) Defective work not remedied or other obligations hereunder not done. b) Claims filed or reasonable evidence indicating probable filing of claims. gencond.mst/spec master GC -26 c) Failure of the Contractor to make payments properly to Subcontractors or for material or labor. fl g) d) Damage to the Owner or another contractor's work, material or equipment. e) Reasonable doubt that the work can be completed for the unpaid balance of the contract amount. Reasonable indication that the work will not be completed within the contract time. Other causes affecting the performance of the contract. 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. 5.09 Delayed Payments Should the Owner fail to make payment to the Contractor of the sum named in any partial or final statement, when payment is due, then the Owner shall pay to the Contractor, in addition to the sum shown as due by such statement, interest thereon at the rate of six percent (6 %) per annum, unless otherwise specified, from date due as provided under "Partial Payments" and "Final Payment," until fully paid, which shall fully liquidate any injury to the Contractor growing out of such delay in payment. It is expressly agreed that delay by the Owner in making payment to the Contractor of the sum named in any partial or final statement shall not constitute a breach of this contract on the part of the Owner nor an abandonment thereof nor shall it to any extent or for any time relieve the Contractor of his obligations to fully and completely perform hereunder. 6. Extra Work and Claims 6.01 Change Orders Without invalidating this agreement, the Owner may at any time or from time to time order additions, deletions or revisions to the work; such changes will be authorized by change order to be prepared by the Engineer for execution by the Owner and the Contractor. The change order shall set forth the basis for any change in contract price, as hereinafter set forth for extra work, and any change in contract time which may result from the change. In the event the Contractor shall refuse to execute a change order which has been prepared by the Engineer and executed by the Owner, the Engineer may in writing instruct the Contractor to proceed with the work as set forth in the change order and the Contractor may make claim against the Owner for extra work involved therein, as hereinafter provided. gencond.mstlspec master GC -27 6.02 Minor Changes The Engineer may authorize minor changes in the work not inconsistent with the overall intent of the Contract Documents and not involving an increase in contract price. If the Contractor believes that any minor change or alteration authorized by the Engineer involves extra work and entitles him to an increase in the contract price, the Contractor shall make written request to the Engineer for a written field order. In such case, the Contractor by copy of his communication to the Engineer or otherwise in writing shall advise the Owner of his request to the Engineer for a written field order and that work involved may result in an increase in the contract price. Any request by the Contractor for a change in contract price shall be made prior to beginning the work covered by the proposed change. 6.03 Extra Work It is agreed that the basis of compensation to the Contractor for work either added or deleted by a change order or for which a claim for extra work is made shall be determined by the unit prices upon which this contract was bid to the extent such work can be fairly classified within the various work item descriptions and for work items that cannot be so classified by one or more of the following methods: Method (A) By agreed unit prices; or Method (B) By agreed lump sum; or Method © If neither Method (A) nor Method (B) is agreed upon before the extra work is commenced, then the Contractor shall be paid the "actual field cost" of the work, plus fifteen percent (l5 %). In the event said extra work is performed and paid for under Method (C), then the provisions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost to the Contractor of all workmen, such as foremen, timekeepers, mechanics -and laborers, and materials, supplies, trucks, rentals on machinery and equipment, for the time actually employed or used on such extra work, plus actual equipment, for the time actually employed or used on such extra work, plus actual transportation charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such extra work, including Social Security, Old Age Benefits and other payroll taxes, and a rateable proportion of premiums on gencond.mst/spec master GC -28 performance and payment bonds and maintenance bonds, public liability and property damage and workers' compensation, and all other insurance as may be required by any law or ordinance, or directed or agreed to by the Owner. The Engineer may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made available to the Engineer. The Engineer or the Owner may also specify in writing, before the work commences, the method of doing the work and the type and kind of machinery and equipment to be used; otherwise these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be determined by using one hundred percent (100 %), unless otherwise specified, of the latest schedule of Equipment Ownership Expense adopted by the Associated General Contractors of America. Where practicable the terms and prices for the use of machinery and equipment shall be incorporated in the written extra work order. The fifteen percent (15 %) of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, general superintendence and field office expense, and all other elements of cost and expense not embraced within the "actual field cost" as herein defined, save that where the Contractor's camp or field office must be maintained primarily on account of such extra work; then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for extra work of any kind will be allowed unless ordered in writing by the Engineer. In case any orders or instructions, either oral or written, appear to the Contractor to involve extra work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the Engineer for written order authorizing such extra work. Should a difference of opinion arise as to what does or does not constitute extra work, or as to the payment therefor, and the Engineer insists upon its performance, the Contractor shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as provided under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to mediation or litigation. 6.04 Time of Filing Claims It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Engineer within thirty (30) days after the Engineer has given any directions, order or instruction to which the Contractor desires to take exception. The Engineer shall reply within thirty (30) days to such written exceptions by the Contractor and render his final decision in writing. In case the Contractor should appeal from the Engineer's decision, any demand for mediation shall be filed with -the Engineer and the Owner in writing within ten (10) days after the date of delivery to Contractor of the Engineer's final decision. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to any claims by either party, except claims by Owner for defective work or enforcement of warranties and except as noted otherwise in the Contract Documents. gencond.mst/spec master GC -29 6.05 Continuing Performance The Contractor shall continue performance of the contract during all disputes or disagreements with the Owner. The production or delivery of goods, the furnishing of services and the construction of projects or facilities shall not be delayed, prejudiced or postponed pending resolution of any disputes or disagreements, except as the Owner may otherwise agree in writing. 7. Abandonment of Contract 7.01 Abandonment by Contractor In case the Contractor should abandon and fail or refuse to resume work within ten (10) 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 the Contract Documents, then and in that case, where performance and payment bonds exist, the sureties on these bonds shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under contract for the work, may be held for use on the work by the Owner or the surety on the performance bond, or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefor (except when used in connection with extra work, where credit shall be allowed as provided for under Section 6 herein), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. Where there is no performance bond provided or in case the surety should fail to commence compliance with the notice for completion hereinbefore provided for, within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (1) The Owner may thereupon employ such force of men and use such machinery, equipment, tools, materials and supplies as the Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to the Contractor, and expense 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 Contractor under and by virtue of this agreement. In case such expense is less than the sum which would have been payable under this contract if the same had been completed by the Contractor, then the Contractor shall receive the difference. gencond.mstispec master GC -30 In case such expense is greater than the sum which would have been payable under this contract if the same had been completed by the Contractor, then the Contractor and/or his surety shall pay the amount of such excess to the Owner, or (2) The Owner, under competitive bids taken after notice published as required by law, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case there is any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract, such increase shall be charged to the Contractor and the surety shall be and remain bound therefor. However, should the cost to complete any such contract prove to be less than would have been the cost to complete under this contract, the Contractor and/or his surety shall be credited therewith. When the work shall have been substantially completed, the Contractor and his surety shall be so notified and Certificates of Completion and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the contract accounts, certified by the Engineer as being correct, shall then be prepared and delivered to the Contractor and his surety, whereupon the Contractor and/or his surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement within fifteen (15) days after the date of such Certificate of Completion. In the event the statement of accounts shows that the cost to complete the work is less than that which would have been the cost to the Owner had the work been completed by the Contractor under the terms of this contract, or when the Contractor and/or his surety shall pay the balance shown to be due by them to the Owner, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be tumed over to the Contractor and/or his surety. Should the cost to complete the work exceed the contract price, and the Contractor and/or his surety fail to pay the amount due the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the Contractor and his surety at the respective addresses designated in this contract; provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice, the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his surety. Such sale may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any machinery, equipment, tools, materials, or supplies, which remain on the work, and belong to persons other than the Contractor or his surety, to their proper owners. The books on all operations provided herein shall be opened to the Contractor and his surety. gencond.mst/spec master GC -31 7.02 Abandonment by Owner In case the Owner shall fail to comply with the terms of this contract, and should fail to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools and equipment, and all materials on the site of work that have not been included in payments to the Contractor and have not been wrought into the work. Thereupon, the Engineer shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Contractor (at the prices stated in the attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable price, and the amount of all extra work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion and which cannot be utilized. The Engineer shall then make a final statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this agreement and shall certify same to the Owner who shall pay to the Contractor on or before thirty (30) days after the date of the notification by the Contractor the balance shown by said final statement as due the Contractor, under the terms of this agreement. 8. Subcontractors 8.01 Award of Subcontracts for Portions of the Work Unless otherwise specified in the Contract Documents or in the Instructions to Bidders, the Contractor, as soon as practicable after the award of the contract, shall furnish to the Engineer in writing for acceptance by the Owner and the Engineer a list of the names of the Subcontractors proposed for the principal portions of the work. The Engineer shall promptly notify the Contractor in writing if either the Owner or the Engineer, after due investigation, has objection to any Subcontractor on such list and does not accept him. Failure of the Owner or the Engineer to make objection promptly to any Subcontractor on the list shall constitute acceptance of such Subcontractor. The Contractor shall not contract with any Subcontractor or any person or organization (including those who are to furnish materials or equipment fabricated to a special design) proposed for portions of the work designated in the Contract Documents or in the Instructions to Bidders or, if none is so designated, with any Subcontractor proposed for the principal portions of the work who has been rejected by the Owner and the Engineer. The Contractor will not be required to contract with any Subcontractor or person or organization against whom he has a reasonable objection. gencond.mstlspec master GC - If the Owner or the Engineer refuses to accept any Subcontractor or person or organization on a list submitted by the Contractor in response to the requirements of the Contract Documents or the Instructions to Bidders, the Contractor shall submit an acceptable substitute and the contract amount shall be increased or decreased by the difference in cost occasioned by such substitution and an appropriate change order shall be issued; however, no increase in the contract amount shall be allowed for any such substitution unless the Contractor has acted promptly and responsively in submitting for acceptance any list or lists of names as required by the Contract Documents or the Instructions to Bidders. If the Owner or the Engineer requires a change of any proposed Subcontractor or person or organization previously accepted by them, the contract amount shall be increased or decreased by the difference in cost occasioned by such change and an appropriate change order shall be issued. The Contractor shall not make any substitution for any Subcontractor or person or organization who has been accepted by the Owner and the Engineer, unless the substitution is acceptable to the Owner and the Engineer. 8.02 Subcontractual Relations All work performed for the Contractor by a Subcontractor shall be pursuant to an appropriate written agreement between the Contractor and the Subcontractor (and where appropriate between Subcontractors and Sub - subcontractors) which shall contain provisions that: (1) (2) require that such work be performed in accordance with the requirements of the Contract Documents; (3) (4) require that all claims for additional costs, extensions of time, damages for delays or otherwise with respect to subcontracted portions of the work shall be submitted to the Contractor (via any Subcontractor or Sub - subcontractor where appropriate) in sufficient time so that the Contractor may comply in the manner provided in the Contract Documents for like claims by the Contractor upon the Owner; (5) preserve and protect the rights of the Owner and the Engineer under the contract with respect to the work to be performed under the subcontract so that the subcontracting thereof will not prejudice such rights; require submission to the Contractor of the applications for payment under each subcontract to which the Contractor is a party, in reasonable time to enable the Contractor to apply for payment in accordance with this contract; obligate each subcontractor specifically to consent to the provisions of this section. gencond.mst/spec master GC -33 A copy of all such subcontract agreements shall be filed by the Contractor with the Engineer before the Subcontractor shall be allowed to commence work. 8.03 Payments to Subcontractors The Contractor shall pay each Subcontractor, upon receipt of payment from the Owner, an amount directly based upon the value of the work performed and allowed to the Contractor on account of such Subcontractor's work, less the percentage retained from payments to the Contractor. The Contractor shall also require each Subcontractor to make similar payments to his subcontractors. If the Engineer fails to approve a payment for any cause which is the fault of the Contractor and not the fault of a particular Subcontractor, the Contractor shall pay the Subcontractor on demand made at any time after the Certificate for Payment should otherwise have been issued, for his work to the extent completed, less the retained percentage. The Engineer may, on request and at his discretion, furnish to any Subcontractor, if practicable, information regarding percentages of completion certified to the Contractor on account of work done by such Subcontractors. Neither the Owner nor the Engineer shall have any obligation to pay or to see to the payment of any monies to such Subcontractor except as may otherwise be required. 9. Separate Contracts 9.01 Owner's Right to Award Separate Contracts The Owner reserves the right to award other contracts in connection with other portions of the project under these or similar conditions of the contract. When separate contracts are awarded for different portions of the project, "the Contractor" in the contract documents in each case shall be the contractor who signs each separate contract. 9.02 Mutual Responsibility of Contractors The Contractor shall afford other contractors reasonable opportunity for the introduction and storage of their materials and equipment and the execution of their work, and shall properly connect and coordinate his work with theirs. If any part of the Contractor's work depends for proper execution or results upon the work of any other separate contractor, the Contractor shall inspect and promptly report to the Engineer any apparent discrepancies or defects in such work that render it unsuitable for such proper gencond.mst/spec master GC -34 execution and results. Failure of the Contractor to so inspect and report shall constitute an acceptance of the other contractor's work as fit and proper to receive his work, except as to defects which may develop in the other separate contractor's work after the execution of the Contractor's work. Should the Contractor cause damage to the work or property of any separate contractor on the project, the Contractor shall, upon due notice, settle with such other contractor by agreement, if he will so settle. If such separate contractor sues the Owner or initiates an proceeding allowed hereunder on account of any damage alleged to have been so sustained, the Owner shall notify the Contractor who shall defend such proceedings at the Contractor's expense, and if any judgment or award against the Owner arises therefrom the Contractor shall pay or satisfy it and shall reimburse the Owner for all attomey's fees and court costs or other costs which the Owner has incurred. 9.03 Cutting and Patching under Separate Contracts The Contractor shall be responsible for any cutting, fitting and patching that may be required to complete his work, except as otherwise specifically provided in the Contract Documents. The Contractor shall not endanger any work of any other contractors by cutting, excavating or otherwise altering any work and shall not cut or alter the work of any other contractor except with the written consent of the Engineer. Any costs caused by defective or ill-timed work shall be borne by the party responsible therefor. 10. Protection of Persons and Property 10.01 Safety Precautions and Programs The Contractor shall be responsible for initiating, maintaining and supervising all safety precautions and programs in connection with the work. 10.02 Safety of Persons and Property The Contractor shall take all reasonable precautions for the safety of, and shall provide all reasonable protection to prevent damage, injury, or loss to: (1) all employees on the work and all other persons who may be affected thereby: (2) all the work and all materials and equipment to be incorporated therein, whether in storage or off the site, under the care, custody or control of the Contractor or any of his Subcontractors or Sub - subcontractors; and gencond.mst/spec master GC -35 (3) other property at the site or adjacent thereto, including trees, shrubs, lawns, walks, pavements, fences, roadways, structures and utilities not designated for removal, relocation or replacement in the course of construction. The Contractor shall comply with all applicable laws, ordinances, rules, regulations and lawful orders of any public authority having jurisdiction for the safety of persons or property or to protect them from damage, injury or loss. He shall erect and maintain, as required by existing conditions and progress of the work, all reasonable safeguards for safety and protection, including posting danger signs and other warnings against hazards, promulgating safety regulations and notifying owners and users of adjacent utilities.

Not specified. D1 -9 SANITARY SEWER CONSTRUCTION TESTING D1 -9(1) City of Round Rock Sewer System Improvements C. Execution 1. Alignment and Grade Check alignment, grade and visible infiltration by methods of visual internal inspection; and by television inspection. Laser equipment is recommended to test the pipe grade and alignment. a. Visual Internal Inspection 1) Clean pipe of excess mortar, joint sealant and other dirt and debris prior to inspection. 2) Inspect sewer by flashing a light between manhole and/or by physical passage where space permits. Determine from illumination and/or physical inspection the presence of any misaligned, displaced, or broken pipe and the presence of visible infiltration or other defects. b. Internally inspect each line segment utilizing a closed circuit color television camera in the presence of the Engineer. In addition, provide a video tape of the sewer line to the Engineer with tapes to become the property of the Owner following completion of testing. 2. Infiltration or Exfiltration tests The total exfiltration as determined by a hydrostatic head test, must not exceed 50 gallons per inch diameter per mile of pipe per 24 hours at a minimum test head of two feet above the crown of the pipe at the upstream manhole. When pipes are installed below the groundwater level an infiltration test must be used in lieu of the exfiltration test. The total infiltration, as determined by a hydrostatic head test, must not exceed 50 gallons per inch diameter per mile of pipe per 24 hours at a minimum test head of two feet above the crown of the pipe at the upstream manhole, or at least two feet above existing groundwater level, whichever is greater. For construction within the 25 year flood plain, the infiltration or exfiltration must not exceed 10 gallons per inch diameter per mile of pipe per 24 hours at the same minimum test head. If the quantity of infiltration or exfiltration exceeds the maximum quantity specified, remedial action must be undertaken in order to reduce the infiltration or exfiltration to an amount within the limits specified. 3. Low Pressure Air Testing of Gravity Systems ( Exfiltration) a. Test manholes in accordance with Section D1 -7. b. Pipelines Test each section of gravity pipeline between manholes and/or structures after backfilling, separately with equipment and methods as outlined below. 1) Contractor shall perform air tests for all pipe sizes unless the pipe is of concrete construction. Concrete pipe must pass a weir test. 2) Fumish facilities required including necessary piping connections, test pumping equipment, pressure gauges, bulkheads, regulator to avoid overpressurization, and miscellaneous items required. City of Round Rock D1 -9(2) Sewer System Improvements where: a) The pipe plug for introducing air to the sewer line shall be equipped with two taps. One tap will be used to introduce air into the line being tested through suitable valves and fittings, so that the input air may be regulated. The second tap will be fitted with valves and fittings to accept a pressure test gauge indicating internal pressure in the sewer pipe. Additional valve and fitting will be incorporated on the tap used to check internal pressure so that a second test gauge may be attached to the internal pressure tap. The pressure test gauge will also be used to indicate loss of air pressure due to leaks in the sewer line. b) The pressure test gauge shall meet the following minimum specifications: Size (diameter) Pressure Range Figure Intervals Minor Subdivisions Pressure Tube Accuracy Dial Pipe Connection 4 -1 /2 inches 0 -15 psi 1 psi Increments 0.05 psi Bourdon Tube or diaphragm Plus or minus 0.25% of maximum scale reading White coated aluminum with black lettering, 270 degree arc and mirror edge Low male 1/2 inch N.P.T. Calibration data shall be supplied with all pressure test gauges. Certification of pressure test gauge will be required from the gauge manufacturer. This certification and calibration data shall be available to the Engineer whenever air tests are performed. 3) Test each reach of sewer pipe between manholes after completion of the installation of pipe and appurtenances and the backfill of sewer trench. 4) Low Pressure Air Test. The procedure for the low pressure air test must conform to the procedures described in ASTM C -828, ASTM C- 924, ASTM F -1417 or other appropriate procedures, except for testing times. The test times must be as outlined in this section. For sections of pipe less than 36 -inch average inside diameter, the following procedure must apply unless the pipe is to be joint tested. The pipe must be pressurized to 3.5 psi greater than the pressure exerted by groundwater above the pipe. Once the pressure is stabilized, the minimum time allowable for the pressure to drop from 3.5 pounds per square inch gauge to 2.5 pounds per square inch gauge must be computed from the following equation: T - 0 .085 x Dx K Q T = time for pressure to drop 1.0 pound per square inch gauge in seconds K = 0.000419 X D X L, but not less than 1.0 D = average inside pipe diameter in inches D1 -9(3) City of Round Rock Sewer System Improvements Pipe Diameter (inches) Minimum Time (seconds) Length for Minimum (feet) Time for Longer Length (seconds) 6 340 398 0.855(L) 8 454 298 1.520(L) 10 567 239 2.374(L) 12 680 199 3.419(L) 15 850 159 5.342(L) 18 1020 133 7.693(L) 21 1190 114 10.471(L) 24 1360 100 13.676(L) 27 1530 88 17.309(L) 30 1700 80 21.369(L) 33 1870 72 25.856(L) L = length of line of same size being tested, in feet Q = rate of loss, 0.0015 cubic feet per minute per square foot internal surface will be used. Since a K value of less than 1.0 will not be used, there are minimum times for each pipe diameter as outlined below: The test may be stopped if no pressure loss has occurred during the first 25% of the calculated testing time. If any pressure loss or leakage has occurred during the first 25% of the testing period, then the test must continue for the entire test duration as outlined above or until failure. Lines with a 27 -inch average inside diameter and larger may be air tested at each joint. Pipe greater than 36 inch diameter must be tested for leakage at each joint. If the joint test is used, a visual inspection of the joint must be performed immediately after testing. The pipe is to be pressurized to 3.5 psi greater than the pressure exerted by groundwater above the pipe. Once the pressure has stabilized, the minimum time allowable for the pressure to drop from 3.5 pounds per square inch gauge to 2.5 pounds per square inch gauge must be 10 seconds. 5) In areas where groundwater is known to exist, install a one -half (1/2) inch diameter capped pipe nipple, approximately ten (10) inches long, through manhole wall on top of one of the sewer lines entering the manhole. This shall be done at the time the sewer line is installed. Immediately prior to the performance of the line acceptance test, determine ground water level by removing pipe cap, blowing air through pipe nipple into the ground so as to clear it, and then connecting a clear plastic tube to pipe nipple. The hose shall be held vertical and a measurement of height in feet of water shall be taken after the water stops rising in this plastic tube. Divide the height in feet by 2.3 to establish the pounds of pressure that will be added to all readings. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 City of Round Rock D1 -9(4) Sewer System Improvements 4. Deflection Test Deflection test must be performed on all flexible pipes and as outlined below: For pipelines with inside diameters less than 27 inches, a rigid mandrel must be used to measure deflection. For pipelines with an inside diameter of 27 inches and greater, a method approved by the executive director must be used to test for vertical deflections. Other methods must provide a precision of ± two tenths of one percent (0.2 %) deflection. The test must be conducted after the final backfill has been in place at least 30 days. No pipe will exceed a deflection of five percent. If a pipe should fail to pass the deflection test, the problem must be corrected and a second test must be conducted after the final backfill has been in place an additional 30 days. The tests must be performed without mechanical pulling devices. The design engineer should recognize that this is a maximum deflection criterion for all pipes and a deflection test less than five percent may be more appropriate for specific types and sizes of pipe. Upon completion of construction, the design engineer or other Texas Licensed Professional Engineer appointed by the owner must certify, to the Executive Director, that the entire installation has passed the deflection test. This certification may be made in conjunction with the notice of completion required in §317.1(e)(1) of this title (relating to General Provisions). This certification must be provided for the Commission to consider the requirements of the approval to have been met. (i) The rigid mandrel shall have an outside diameter (O.D.) equal to 95% of the inside diameter (I.D.) of the pipe. The inside diameter of the pipe, for the purpose of determining the outside diameter of the mandrel, shall be the average outside diameter minus two minimum wall thicknesses for O.D. controlled pipe and the average inside diameter for I.D. controlled pipe, all dimensions shall be per appropriate standard. Statistical or other "tolerance packages" shall not be considered in mandrel sizing. (ii) The rigid mandrel shall be constructed of a metal or a rigid plastic material that can withstand 200 psi without being deformed. The mandrel shall have nine or more "runners" or "legs" as long as the total number of legs is an odd number. The barrel section of the mandrel shall have a length of at least 75% of the inside diameter of the pipe. A proving ring shall be provided and used for each size mandrel in use. (iii) Adjustable or flexible mandrels are prohibited. A television inspection is not a substitute for the deflection test. A deflectometer may be approved for use on a case by case basis. Mandrels with removable legs or runners may be accepted on a case by case basis. D. Measurement and Payment No contract prices are established for Sanitary Sewer Construction Testing.

The use of a lubricant is recommended and if used such lubricant shall be approved by manufacturer's standards. The manufacturer's standards shall be closely followed during the elevated temperature process curing so as not to over stress the felt fiber and cause damage or failure of the liner prior to cure. In certain cases, the Contractor D2 -12 (3) City of Round Rock Sewer System Improvements may elect to use a Top Inversion. In this method the tube is pre- inverted to a distance that corresponds to the minimum inversion head and instead of attaching to an elbow at the base of the inversion tube, the liner is attached to a top ring. c. After inversion is completed the Contractor shall supply a suitable heat source and water recirculation equipment. The equipment shall be capable of delivering hot water to the far end of the liner through a hose, which has been perforated per manufacturer's recommendations, to uniformly raise the water temperature in the entire liner above the temperature required to effect a cure of the resin. This temperature shall be determined by the resin/catalyst system employed. The heat source shall be fitted with suitable monitors to gauge the temperature of the incoming and outgoing heat exchanger circulating water. Thermocouples shall be placed between the tube and the invert at near and far access to determine the temperature of the tube and time of exotherm. Water temperature in the line during the cure period shall not be less than 150 °F as measured at the heat exchanger return line. Initial cure shall be deemed to be completed when inspection of the exposed portions of the liner appear to be hard and sound and the thermocouples indicate that an exotherm has occurred. The cure period shall be of a duration recommended by the resin manufacturer, as modified for the Insituform process, during which time the recirculation of the water and cycling of the heat exchanger to maintain the temperature in the tube shall be continuous. d. The Contractor shall cool the hardened CIPP to a temperature below 100 °F before relieving the static head in the inversion standpipe. Cool -down may be accomplished by the introduction of cool water into the inversion tube to replace water being drained from a small hole made in the end of the CIPP at the downstream end. Care shall be taken in the release of the static head such that a vacuum will not be developed that could damage the newly installed CIPP. e. The finished CIPP shall be continuous over the entire length of an insertion run and be as free from visual defects such as foreign inclusions, dry spots, pinholes, and delamination. The CIPP shall be impervious and free of any leakage from the pipe to the surrounding ground or from the ground to the inside of the CIPP. Any defects which will affect, in the foreseeable future, or warranty period, the integrity or strength of the CIPP, shall be repaired at the Contractor's expense, in a manner mutually agreed by the Owner and the Contractor. City of Round Rock D2 -12 (4) Sewer System Improvements 7. Completion of CIPP a. If due to broken or misaligned pipe at the access point, the CIPP fails to make a tight seal, the Contractor shall apply a seal at that point. The seals shall be of a resin mixture compatible with the CIPP. b. After the CIPP has been cured, the Contractor shall reconnect the existing active service connections. Reconnection of service connections shall be accomplished by external excavation unless otherwise allowed by the Engineer.

Description Clearing and grubbing shall consist of the removal and disposal of trees, stumps, brush, roots, vegetation, logs, rubbish and other objectionable matter from the designated area. B. Construction Methods 1. The designated area shall be cleared of all trees, brush, shrubbery, plants, etc., not designated by the Owner or indicated on the plans to be preserved. Trees and brush designated to be left in place shall be carefully trimmed as directed and shall be protected from scarring, barking or other injuries during construction operations. Pruned limbs over 2 in. (50 mm) in diameter shall be treated by painting the exposed ends with an approved asphaltic material. Unless otherwise indicated on the plans, trees and stumps shall be cut off or otherwise removed as close to the natural ground as practicable on areas which are to be covered by at least 3 ft. (1 m) of embankment. On areas required for borrow sites and material, sources, stumps, roots, etc., shall be removed to the complete extent necessary to prevent such objectionable matter being mixed with the material to be used in construction. 2. All cleared and grubbed material shall be disposed of by the Contractor. Unless otherwise provided, all merchantable timber removed as previously specified shall become the property of the Contractor. It is the intent of this specification to provide for the removal and disposal of all obstructions and objectionable materials not specifically provided for elsewhere by the plans and specifications. C. Measurement and Payment D2 -19 CLEARING AND GRUBBING Clearing and grubbing shall be measured for payment by lump sum. Measurement for payment shall be made only on areas indicated and classified on plans as clearing and grubbing. Clearing and grubbing shall be paid for at the contract lump sum price, as provided in the proposal and contract. The contract unit price shall be the total compensation for furnishing all material, labor, equipment, tools and incidentals necessary to complete the work, all in accordance with the plans and these specifications. When not listed as a separate contract pay item, clearing and grubbing shall be considered as incidental work, and the cost thereof shall be included in such contract pay items as are provided for in the proposal contract.
