CHANGES IN TIfE WORK AND CI %IMS 6.01 CHANGE ORDERS: Without invalidating this Agreement, the OWNER may, at any Lillie 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 OWNER 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. 6,02 MINOR CIPANGES: The ENGINEER may authorize minor changes in the work not inconsistent with the overall intent of the Contract Documents and not in- volving an increase in Contract Price. If the CONTRACTOR believes that any minor change or alteration authorized by the ENGINEER. involves ':xtra 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 also shall advise in writing the OWNER of his request to the ENGINEER for a written Field Order and that the work involved may result in an Increase in the Contract Price. 6.03 EXTRA WORK: It Is agreed that the basis of compensation to the CON- TRACTOR for work either added or deleted by a Change Order or for which a claim for rxtra Work Is made shall be determined by one or more of the follow- ing methods: Method (A) - By agreed unit prices; or Method (B) - By agreed liimp sum; or Method (C) - If neither 'Method (A) nor Method (B) be an-.recd upon before the Extra Work Is commenced, then the CON'rRACrOR shall be paid the "actual field cost" of the work, plus fifteen (15%) percent, 24 Rov 12-1-67 In the event said Extra 'pork be performed and paid for under Method (C), then the provisions of this paragraph shall apply and the.- "actual field cost" is hereby defined to Include the cost to the CONTRACIOR of all workmen, such as Foremen, timekeepers, mechanics and laborers, and ri,ntvrlnis, supplies, teams, bucks, and rentals nn machinery and equipment, for lie time. actually employed or +isr-d on such Extro Kork, plies actual tronsportatir,r, charf~es necessarily incurred, Loa ether with all power, fool, luhricantS, w-+tor and similar operating expenses, also all neces5ar1V incidental axp,nFCS Inc+irred directly on account of suc1+ h:xtra Work, including Social Y,cutA1-j, Old Apo Benefits, and other payroll taxes, and a rateable propvrtioga of preroi+gms on Performance and Payment Bonds, and PdefraLenance Bonds, ru+d nn FU1JHC Liability arid Property Damage, and h'orkmcni's Compensation, and all other insurance as may be required by anv law or oruinance, or directed in writing by tht. EN,:,INEER. The ED,GINEFR may direct the form in which accounts of the "actual field cost" shell be kept and the records of Chase accounts shall be made available to the ENGINEER. The ENGINEER shall also specify in writing, before the work ccrrm nces, the method of doing the work and the type and kind of machinery and equipment to be used. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be determined by using 100 percent, unless otherwise specified, of the schedule, current at the time of such use, 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 Change Order. The fifteen (15X) percent of the "actual field cost" to be paid the CONTRACTOR shall cover and compensate him fcr 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 solely 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 he allowed unless ordered in writing by the ENGINEER. In case any orders or instructions, either oral or written, appear to the CONTRAC'rOR to Involve Extra Work for which he should receive compensation or an adjustment In the construction time, lie shall make written request to the ENGINEER for written order authorizing such Extra Work and he shall advise the OWNER of his request to the ENGINEER. Should a ,flfference 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 P,rder 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 suhmit the matter of payment to arbltratlon, as lierein>>elr.w ;rrovided. 6,0; TIME OF FILING CLAIMS. It Is further agreed by both parties ieroto that all questions of dispute or adjustmenL presented by the C0%TiRACTOR shall be in writing and filed with the ENGINEER within fifteen (l)) davs after the EJ,1I;':ER has given sny directions, order or instroction to which the COYfRACf0R &-sires to take exception, The ENGINEER shall, within fifteen (15) days, reply to such written exceptions by the CONTRACIOR and render his final decision in Rev 12-1-h7 25 writing. In case the CONTRACTOR should appeal from the ENGINEF'R'S decision, any demand for arbitration shall be filed with the ENGINEER and the OWNTR in writing within ten (10) days after the date of delivery to CO;flRACTOR of the ENGINEER'S final decision. It is further agreed that final acceptance of the work by the OWNER and the acceptrinc•e by the CONTRACTOR of tho Iinal payment shall bn a bar to any cl.iirns by either party, except where nolvrl otherwise in the Contract Documents. 6,05 ARBITRATION. All questions of dispute under this Aprerungnt shall be sub- mitted Co arbitration at the request of :mlther party to the dit,pite. The parties may agree upon one arbiter; otherwise, there shall b(. tliree, one named in writing by each party, and the third chosen by the two arbiters so selected; or If the arbiters fail to select a third within ten (10) days, he shall be chosen by a District Judge serving the County in which the major portion of the project is located, unless otherwise specified. Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his rights to arbitrate shall lapse, and the decision of the ENGINEER shall be final and binding on him. Should tile other party full to choose an arbiter within ten (10) days, the NEGINEER shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or informotion demanded In writing, the arbiters are empowered by both parties to take ex parte proceeding. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any question submitted to arbitration under this contract shall be a condition precedent to any right of legal action. The decision of the arbiter or arbiters may be filed in court to carry it into effect. 7. ABANDONMENT OF CONTRACT 7701 ABANDONMENT BY CONTRACTOR. In case the CONTRACTOR should abandon and fail or refuse to resume work within ten (10) days after written notif.cation from the OWNER, or the ENGINEER, or if the CONTRACTOR fails to comply with the orders of the £NC1=r'--R, when such orders are consistent with the Contract Documents, then, and in that case, where performance and payment bonds exist, the Surety on the bonds shall be notified In writing and directed to complete the work, and a copy of said notice shall he 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 bo held for use o.i the work by the OWNCR or tho Surety on the performance and payment bonds, or another contractor In com- pletion of the work; and tha CONTRACTOR shall not receive any rental or credit therefor (except when used in connection wit) Extra ',n rk, w%o re credit shall be allowed as provided for under Section 6, Changes In the Work and Claims), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. Rev 12-1-67 26 Where there is no perfonnanco 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 servire of such notice, then the OWNER may provide (or completion of the work In clther of the following elective manners: 7.011. 'lho OWN-X may the:CUpon employ such force of men and us-3 such ma- chinery, equipment, tools, materials, and suppitos as said 014NER may deem necessary Lo complete the work and chargo the expense of such labor, machinery, equipment, tools, materials, and snpplics to said CONTRACTOR, and expense so chargcd shall be deducted and paid by the OWNER out of .Srich moneys as may be due, or that may therea[tor at any LImc, become due t0 the CONTRACTOR under and by virtue of this Agreement. In case such expense is tess than the sum which would have boen payable under this contract, If the sumo had been completed by the CONTRACTOR, then said CONTRACTOR shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said CONTRACTOR, then the CONTRACTOR and/or his Surety shall pay the amount of such excess to the OWNER; or 7.M. The OWNER, under scaled bids, after five (5) days notice published one or more times in a newspaper having general circulation In the county of the location of the work, may let the contract for the completion of the work under substantially the some terms and conditions which are provided In this con- tract. In case of any Increase in cost to the OWNER under the new contract as compared to what would have boon the cost under this contract, such Increase shall be charged to the CONTRACTOR and the Surety shalt ho 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 CONTRACTOR and/or his Surety shall be credited with the difference. 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 amounts, certified to by the ENGINEER as being correct, shall then be prepared and delivered to the CONTRACTOR and his Surety, whereupon the CONTRACTOR and/or his Surety, or the OWNER as the case may be, shall pay the balance due as reflected by said statement, within fifteen (15) days after the date of such Certificate of Completion. In the event the statement of accounts shows that the cost to complete the work Is less than that which would have been the cost to the OWNER had the work been completed by the CONTRA('"OR under the terms of this contract; or when the CO"1fRACTOR and/or his Surety shall pa, Vie balance shown to be due by then to the OWNER, then all machinery, equipvrrnt, tools, mntertais, or supplier, left on the site of the work shal' be turned over to the CONTRACTOR and/or his Surety. Should the cost to complr!to the work exceed the contract price, and the t:ONiRACTOR and/or his Surety fall to pay the artount due the OWN'FR wiLhin 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 equlpment and materials, shall be mailed to the 27 Rev 12-1-67 CONTRACTOR and his Surety at the respective addresses dasIgnated in this contract; provided, however, that actual written notice givon In any manner will satisfy this condition. After mailing, or other givin;, 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 (11) days from the date of said noiico, the OWNER may sell such machinery, equiprnenl, tools, nwterials, 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 with- out notice, as the OWNER may elect. The OWNER shill release any machinery, equipment, tools, materials, or supplies, which remain on the work and belong to parsons other than the CONTRACTOR or his Surety, to their proper owners. The books on all operations provided herein shall be open tr, the CONrRACTOR and his Surety. 7.02 ABANDONMENT BY OWNER. In case the OWNER shall fail to comply with the terms of this contract, and should fail or refuse 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 rachinery, tools and equipment, and all materials on the site of the work that have not been Included in payments to the CONTRACTOR and have not been wrought Into the work. And thereupon, the ENGINEER shall make an estimate of the total amount earned by the CONTRACTOR, which estimate shall include the value of all work actually completed by said CONTRACTOR (at the prices stated in the attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of his contract, and a reasonable sum to cover the cost of any pro- visions made by tho CONTRACTOR to carry the whole work to completion and which cannot be utilized. The ENGINEER shall then make final statement of the balance due the CONTRACTOR by deducting from the above estimate all pre- vious 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 state- ment as due the CONTRACTOR under the terms of this Agreement..

Where the term "Or Approved Equal" is used, It Is understood that if a material, product or piece of equipment of the speclfled name and quality is furnished it will be approvable, as the particular trade name and quality was used for the purpose of establishing a standard of quality acceptable to the Owner. If a product of any other name is proposed for use, the Engineer's approval thereof must be r.,bt,,Ined before the proposed substitute is procured by the Contractor. Wherever the term "Or Equal" is used, It is understood to mean "Or Approved Equal". B. Workmanship: These specifications contain detail instructions and descriptions covering the major items of construction and workmanship necessary for building and completing; the various units or elements of the project. The specifications are intended to be so written that only first class workmanship and finish of the hest grade and quality will result. The fact that these specifications may fall to he so complete as to cover all details will not relieve the Contractor of full responsibility for providing a completed project of high quality, first class finish and appearance, and satisfactory for operation, all within the apparent Intent of the plans and specifications. C. Handling _Materials not Approved: The Contractor shall remove from the site any materials found to be damaged, and any materials not meeting the specifications. These materials shall be removed promptly, unless the Engineer will accept the materials after repairing. Materials found to be damaged, or not acceptable to rho Engineer, shall be removed if installed and then found to he damaged or not cjcceptahle. inspection before Install- ation shall not: relieve the ('mtr,ictcr faun rrrr,r respr,t~sibility to furnish good quality treaterlals.

Wire gates shall provide a clear opening of thirty (301) feet and shall lie constructed as shr,wi, on the Plans. The full opening of thirty (301) feet shall be reduced to one half this dis- tance (15-feet) by the Instalintion of a line post in the center of the opening, except during the actual trenching operations. Cuts in fences shall be made In a neat and workmanlike manner and the Contractor shall be responsible for prevention of loss of stock or pets through gates, breaks. or gaps in fences due to construction operations. Where gates are installed in the fences, two "fi" Frame braces shall be installed in the fence line on each side of the gate as shown on the Plans. G. Safety and Property Protection: 1. Barricades, Guards and Safety Provisions: To protect persons from injury and to avoid property damage, adequate barricades, construction signs, torches, red lanterns and guards as required shall be placed at all road or street crossings, and maintained during the progress of the construc- tion work and until it is safe for traffic to use the construction site. Whenever required, watchmen shall be provided to prevent accidents and no extra compensation will be allowed therefor, Rules and regulations of the local authorities respecting s.fety provisions shall be observed, 2. Traffic and Utility Controls: Excavations for construction operations shall be conducted in a manner to cause tree lenst Interruption of traffic. Where traffic must cross open trenches, the Contractor shall provide suitable bridges at road crossings, street intersections, and driveways. 3. Flow of Drains and Sewers Maintaitied: Adequate, provisions shall be made for the flow of storm sewers, dr~ilns and wattr (nurses encountered during the constructicn and the SeruCtures which 14:y have been disturbed shall be satisfactorily restored upon corpletion of the work. 4. Property Protection: Trces, fenccs, signs, poles, guy wires, and all other property shall be protected unless their removal Is authorized; and any property damage shall be satisfactorily restored by the Contractor. Eh'D OF SECTION 101-2 SECTION 102 - EXCAVATION AND BACKrILL A. General: The Contractor shall make such excavations as may be required for the construction of the facilities to line, grade and extent indicated on the Plans, or as may be required for the construction of structures, installation of piping and all incidentals thereto. Excavations shall be dewatered so that all work may be performed in the "dry". The Contractor, at his expense, shall do all bailing, pumping and dewntering as may be required. All water removed from trenches shall be conducted to natural drainage ways, drains or storm sewers in such a manner as to prevent damage to adjacent property or to the public. Pumps of ample capacity and in duplicate must be provided to insure that once an excavation is made dry, the water will be kept down until that part of the work under construction Is completed, B. Classification of Excavation: All excavation shall be "unclassified" and involves the removing of all materials necessary to permit the carrying on and cumpleting of the work, The Contractor, prior to submitting a proposal, must satisfy himself as to the actual sub-surface conditions. No extra or separate payments for rock excavation will be made. C. Structural Excavation: Excavation shall extend a sufficient distance from walls and footings to allow for forms, installation of services, and for inspection, except where concrete for walls and footings is authorized or required to be deposited directly again,t excavated surfaces. Where excavation, through the fault of the Contractor is madc. below the elevation indicated on the drawings or directed by the Engineer, the excavation shall be restored to the proper elevation with stabilized backfill (lean concrete) or other approved material, at the expense of the Contractor, D. Trench Excavation 1. General: The trenches shall be excavated to the alignment and de?th as shown on the Plans or as required for the proper installation of the pipe. The trench shall be braced and/or dewatered, if necessary, in such manner that the workmen may work therein safely and efficiently, 2. Trench Width: The trench walls In the pipe z,)ne, from the trench bottom to at least one (10) foot above the top of the pipe, shall be vertical. The walls of the excavation above this specifically deslgtiated pipe zone shall be substantially vertical. The minimum and maximum width of trench excavation at the top of the pipe zone, measured one (11) foot above the top of the pipe, shall conform to the following requirements, Vie minimum width of trench shall be the external diameter of the pipe plus fifteen (1511) inches. The maximum width of trench shall be the external d1ar* ter of the pipe plus twenty-four (24") inches, except where addi- tional width is required and approved at pipe joints. 102-1 3. Pipe Foundations The trench shall be excavated to an even grade to permit the installation of the pipe in such a manner that the full length of the pipe barrel is supported on the trench bottom. The entire foundation area in the bottom of all oxcavations shall be firm, stable material, and material shall Not be disturbed below ` required grade except as hereinafter described. Where the character of the foundation materials is such that a proper foundation cannot be obtained at the elevation indicated by the plans, then, when directed by the Engineer in writin;, the Gonuractor shall deepen the excavation to where a satisfactory foundation can be obtained. If the subgrade is soft, spongy, or disintegrated, the materials shall be removed until a firm, stable and uniform benring is reached and the subgrade brought back to the required grade with material compacted in place or with granular or concrete embedment material. If the unsatis- factory subgrade condition is due to the Contractor's failure to make a proper provision for adequate drainage of excavations, the expense of replacing any unsatisfactory subgra e shall be borne by the Contractor. However, if in the opinion of the Engineer, the unsatisfactory subgrade condition is not the result of the failure of the Contractor to provide adequate drainage, bailing or pumping facilities and the Engineer orders in writing that the Contractor make additional excavation and replace unsatisfactory subgrade material, then compensation will be made for the additional expense incurred. 4. Correctinp1 Faulty Grades Any part of the trench excavation below grade shall be corrected with approved material, thoroughly compacted. j, Pipe Clearance in Rocks Ledge rock, rock fragments, or unyielding shale or marl shall be removed to provide a clearance of at least six (6") Inches below all parts of the pipe, valves or fittings. Adequate clear- ance for properly jointing pipe laid in rock trenches shall be provided at bell holes. 6. Sub-Grade in Rock Treachs The excavation below sub-grade in rock or unyielding shale or marl minimum excavation of six (61 inches) shall be refilled to grade with Embedment Material. The Embedment Material shall be brought up to the spring line of the pipe as shown on the plans and shall conform to the requirements for "Pipe Embedment." Section 104. Embedment material shall be placed is specified under "Backfilling of Trenches," 7. Blasting Procedures Blastinj for excavation will be permitted only after proper precautions are taken for the protection of persons and property. Any damage caused by blasting :hail be repaired by the Contractor at his expense. The Contractor's methodn of procedure relative 102-.. 1 to blasting shall conform to local and state laws. The Contractor shall cover all blasting operations with wire netting of adequate strength and adequately anchored to prevent the scattering and flying of rock and debris from the site of blasting. No blasting will be permitted within three hundrod (300') feet of any water wells or oil welln nor within 40 feet of existing concrete cylinder water pipe line, 8. Pell Hole- He ud iredi Dell hole!; of ample dimension shall be dug in trenches at each Joint to permit the jointinug t() bo made properly and to that the pipe will rest on the full length of th,, ha rrel. 9. Braced and Sheeted lrenc'nes: Wherever necessary to prevent caving excavation shall be adequately sheeted and braced. Where sheeting and bracing aye used, the trench width shall be increased accordingly. Trench sheeting shall remain in place u;itil the pipe has been laid, tested for defects, a,id repairei if necessary and thr,, trench backfilled to a depth of two feet over the top of the pipe, 10, Care of _Surface Material for Re-Uses If local conditions permit their reuse, all surface materials suitable for reuse in restoring the surface shall be kept separate from the general excavation material. 11. Manner of Piling Excavated Materials All excavated material shall be placed in a manner that will not enda„ger the work and will interfere as little as possible with public traffic. Roads and driveways must be kept open in every possible case, with exceptions to be made only upon permission from the Engineer. Drainage channels shall be kept clear of obstruction or other satisfantory provisions made for drainage. 12. Trenching by Machine or by Han di The use of trench digging machinery will be permitted except in places where operations of same will cause damage to existing structures above or below ground, in which case hand methods shall be employed. 13, Open Trenchi The Engineer shall have the right to limit the amount of trench which may be c,^.er:ed or partially opened at any time in advance of the completed lines and also the amount vi irench left not backfilled. Not over 1,500 feet of trench shall be left open ahead of pipo laying. E. Protection of Existing Structures and Utilities In the preparation of plans and specifications, the F,rzgineer has endezuored to indicate the location of all principal ezistinb underground lines which are known to the Engineer. No attempt h,,-Ls bean made to show minor lines or service lines. However, it is z,ot guaranice.i that all lines or structures have been shown on the Flans. Prior tc the start of construction, the Contractor shall communicato with the local reprel~nntative of the oil companies and utility companles, including but not limitod to the oil companies, gas company, telepl,r,u company and any other public and private utility nompanies, am'. alvise said roprosentatives of the route of the proposed construction in order to obtain the assist+nce of the utility companies in the) location oc and in tho avoidance of conflicts with utility lines. 1J2-3 Where excavation endangers adjacent struetaren and utilities, the Con- tractor shall, at his own expense, carefully support and protect all such structures and/or utilities so that there will be no failure or settlement, Where it is necessary to move services, poles, guy wires, pipe lines, or other obstructions, the Contractor shall notify aril cooperate with the utility owner. In case damage to an existin3 structure or utility occurs, whether failure or settlt,ment, the Contractor shall restore the structure or utility to its original condition a rni position without co:pcnsation from the Owner. All costs of temporarily or permanently relo sting the conflicting utilities shall be borne by the Contractor without extra compensation from the Owner. If, in the opinion of the Engineer, concrete backfill is necessary for the support of utility lines crossing trenches, the Engineer may direct 15CO lbs, concrete backfill be used. Payment will be made to the Contractor at the unit price bid for the installation of such quantity of the concrete backfill as directed by the Engineer. F. Backfilling Around Structureoi Excavation around structures shall be backfilled with excavated or other material to the elevationi shown on the plans. Backfill material shall be select n,iterial free from rock or boulders measuring more than eight (6") inches in its greatest dimension. Normally the backfill material may be dumped or pushed into the excavation and be stabilized by flooding and ,jetting. However, where directed by the Engineer, the backfill material shall be placed in layers not to exceed six (61 inches in thickness, adding sufficient water to moisten the materials, if dry, and shall be compacted by hand or pneumatic tamping until the backfill la of the same density as the undisturbed earth in the sides of the excavation. G, Backfilltng of Trenches, Clean Up and Main_tainigZ Surfacest 1, Time of Backfillingi As soon as the pipe joint has been completed and the outside Joint space has boon filled with Totar and the mortar has "set up" the Contractor shall proceed with the backfilling operations. At no time shall the completely backfilled trench be more than 590 feet behind the pipe laying. 2. Backfill Procedure Below Centor Axis of Selected backfill material free From rock fragments shall be depositei in the trench simul- taneously on outh sides of the pipe for the full width of the trench and to an elevation even to the center axis of the pipe, In trenches in which rock excavation was encountered, or if ordered by the Engineer, this backfill material shail to Embedment Material (see Section 194), Backfil material frog the bottom of thi+ trench to the center of the pipe shall be placed In six (6'') inch layers, maiotened to approximate optimum moisture, and thoroughly compacted with pneumatic tamps up to the center of the pipe, Adequate care shall be takon to insure proper com piction under the pipe near the center of the trench. 102-4 As an alternate to the above method of compaction, loose material may be placed in one operation from the bottom of trench to slightly above pipe center line. This material shall then be compacted by use of water applied through a jet pipe. The water shall be applied under pressure, and bj forcing the jet pipe down into the material on each side of the pipe at close inta"ale so that the backflll will he thoroughly saturated argil will melt and flow snler the pipe for its entire length. The apparatus for apply1n3 water for compaction by this method will be subject to the Engineer's appruval to the extent that it must be capable of supplying water in sufficient quantity ami pressure to accomplish the desired result. Tho Contractor shall perform the jetting in the floated or such a manner to prevent floating the pipe. Any pipe which atIs is otherwise disturbed shall be relaid to the original I,r expense; Water flooding; may be employed in lieu of jetting, provided satisfactory compaction can be obtained. 3. Backfill Procedure Above Center Axis of Piper a. Backfill Beneath Pavements Backfill in areas where paving is to be replaced shall be made with approved moist material, thoroughly com- pacted in about six (6") inch layers, and brought to a point 11-0" below the finished paved surface. The final 10 " section of backfilA shall be made with stabilized material. The stabilized material shall be composed of cement and aggregate in the ratio of two O sacks or cement per cubic yard of aggregate. The ag„re;ate may be "pit-run" sand and gravel. The mntorial shall be mixed in a miner with Just enough water to "set-up" the material. The material shall be placed in the trench in uniform layers of approximately six (6") inches .and thoroughly tamped.

In the determination of the amount of water required for mix, consideration shall be given to the moist ire content of the aggregate. The net amount of water in the mix will be the amount added at the mixer; plus the free water in the aggregate; and minus the absorption of the aggregate, based on thirty (30) minutes absorption period. No water allowance will be made for evaporation after batching. The methods of measurement of materials shall be such that the proportions of water to cement can be closely controlled during the progress of the work and easily checked at any time by the Engineer or his r-presentatives. To avoid unnecessary or haphazard changes in censistency, the aggregates shall be obtained from sources which will. Insure a unifotm quality and grading during any Single day's operation and they shall be delivered to the work and handled in such manner that the variations in moisture content will not interfere with the steady production of concrete of reasonable degree of uniformity. All sources of supply shall be approved by the engineer. All materials shall be separately and accurately measured. Measurement may be made by weight or by volume, as may be elected by the Contractor; however, all equipment for measurement of nkiterials shall be subject to approval by the Engineer. The proportions of the mix shall be such as to produce concrete that can be puddled readily into the corners and angles of the forms and around the rein- forcing without excessive spading or vibrating, anc; without segregation or undue accumulation of water or laitance on the surface. D. Placing Concrete: The Contractor shall give the Engineer sufficient advance notice before starting to place concrete in any unit of the structure to permit the inspection of forms, the reinforcing steel placement, and pre- paration for pouring. Unless authorized by thc, ingineer, no concrete shall be placed in any unit prior to the completion of all foTllk work and the placement of all reinforcement for that unit. The sequence of placing concrete shall be -is provided on the plans or in the specifications.

END OF SECTION 116-1 SECTION 117 - HYDROSTATIC TEST AND STERILIZING OF WATF'R ?A NFS A. General: After the pipe has been laid and backfilled, but prior to re- placement of pavement, each valved section of newly laid pipe shall be sub- jected to a hydrostatic pressuro test by raising the pressure in the various sections of the line, between main line valves, so that. the pressure in the lowest point of the section being tested is 150 pound; per square inch. Ad- justment as required shall be made for differential in elevation between the low point of the section being tested and center line of pressure test gauge. The duration of each pressure test shall be four (4) hours. B. Procedure: The Contractor may test the pipe line In sections when all the pipe in the section is at least 28 days old. The test shall be made against valves when available, or by placing temporary bulkheads in the pipe, and filling the line slowly with water. Care shall be used to see that all air vents are open during the filling. After the line, or section thereof, has been completely filled, it shall be allowed to stand under a slight pres- sure for at least 48 hours to allow the lining to absorb what water it will and to allow the escapte of air from any air pockets. During this period, the bulkheads, valves, manholes, and connections shall be examined for leaks. If any are found, these shall be stopped or, in the case of valves in the main line or Bulkheads, provusion shall be made for measuring the leakage during the test. The water necessary to maintain the test pressure shall be measured through a meter or by other means satisfactory to the Engineer. Contractor shall furnish all necessary equipment and make tests at his expense. Before applying the specified test pressure, all air shall be expelled from the pipe. In the event it is necessary to expell air from high points other than where taps are provided, the Contractor may tap the line for this purpose and afterwards tightly plug the tap. These taps must be made by the pipe manufacturer. No extra compensation will be made for these taps. C. Examination Under Pressure: During the last two hours of the test, the entire route of the pipe line shall be inspected to locate any leaks or breaks. Any defective joints, cracked or defective pipe, fittings, or valves discovered in consequence of this pressure test shall he removed and replaced with sound material in Cie manner provided and the test shall be repeated until satisfactory results are obtained. Any and all noticeable leaks shall be repaired regardless of whether the actual leakage is within the allowable. D. Permissible Leakage: No pipe installation will be accepted until the leakage 19 less than the number of gallons per hour as determined by the following formula: "P LN D Y_ 1,850 Where L equals the allowable leakage in gallons per hour; N equals the number of joints in the length of pipe tested; D equals the nominal diameter of the pipe in inches; and P equals the average test pressure In pounds per square inch. 117-1 Rased on this formula the permissible leakage p,~r 100 pipe joints per hour, at an average test pressure of 150 psi, is as follows: Pipe Size Permissible U.,Y++{;e per 100 Joints in CI'11 fn150 si) 6" 3.91 pR 5.30 12" 1.94 16" 10.59 18" 11.92 24" 1.1.8P, Should any test of pipe in place disclose leakage greater than that specified, the Contractor shall at his own expense locate and repair the defective joints until the leakage is within the specified allowance. E. Leakage Defined: Leakage is defined as the quantity of water to be supplied into the newly laid pipe, or any valves section of it, necessary to maintain the specified leakage test pressure after the pipe has been filled with water and the air expelled. F. Sterilizing of Mains: The Contractor shall sterilize all new mains, fur- nishing all labor, equipment and material necessary to the complete sterili- zation of the mains as herein provided and the satisfaction of the Engineer. Mains shall be sterUl zed by the application of a chlorinating agent into the water used for the initial filling of the mains. The chlorinating agent may be a chlorine gas-water mixture, calcium hypochlorite in water, or chlorinated lime of known chlorine in water and shall be fed through a suitable srlution feed de- vice. The chlorinating agent shall b applied at or near the beginning point from which the main is being filled and shall be injected into the main through a corporation cock tapped into the horizontal axis of the newly laid pipe. The water being used to fill the line shall he controlled to flow into the section to be sterilized very slowly and the rate of application of the chlorinating agent shall be in such proportion to the rate of water entering the pipe that the chlorine dose applied to the water shall he at least 50 parts per million. The chlorine- treated water shall be retained in the rain until the completion of the pressure test hereinbefore specified (not less than twenty-four hours). After the chlorine-treated water has been retained for the required time, the chlorine residual at the pipe extremeties and at other representative points shall be flushed from the miius until the remaining water shall have a chlorine content not in excess of 0.2 parts per million, and no water containing a higher chlorine content shall be permitted to flow into the existing system of the (rmer. END OF SEC110"t 117-2 SECTION 118 - CLAY SEWER PIPE A. General: Clay sewer pipe as furnished for this project shall conform to ttie strength classification as shown on the plans, and shall comply in all respects with these specifications. 8. Materials: All vitrified clay sewer pipe and fittings shall be number one quality, true to lines and circles within tolerances as outlined in these specifications. Pipe and fittings shall comply In all respects with the Specifications of the American Society of Testing Materials latest designation for Standard Strength Clay pipe, C-13 or C-261, or Extra Strength Clay Sewer Pipe, C-200 or C-278, except as modified hereinbelow. These specifications are intended to be so written that either glazed or unglazed clay sewer pipe will be acceptable. Pipe shall have pre-formed compression type joints. All pipe and specials shall be of the bell and spigot pa:tarn. Pipe shall be sound and thoroughly burned throughout, smooth on the inside and free from blisters, lumps or flakes which are greater than one-sixth (1/6) of the thickness of the pipe or one-eight (1/8) inch, whichever is the least. Tile pipe shall be free from fire cracks of any kind extending through the shell, and shall be well formed and straight. Tolerances as given in the ASTM specifications will form the basis of acceptance in regard to variations in dimensions with the further stipulation that pipe having dimensions which vary to the extent of causing difficulty in joint making will be rejected. It is further the intent of these epectfications that the spigot can be inserted into the bell, and that joint making can proceed im- mediately without having to turn the pipe in an effort to match oversized dimensions in the bell with oversized dimensions on the spigot. It is intended that these specifications describe a minimum quality which will be acceptable and the supplier will be expected to exceed these requirements. The Owner's representative reserves the right to mark all rejected pipe in a manner so that it can be easily identified, and this Contractor shall immediately remove any rejected pipe from the project site. C. Laying Clay Sewer Pipe: Upon the required embedment, the pipe shall be laid to the line and grade shu4n on the plans. The Engineer will provide offset stakes at 100 foot intervals, and will provide the Contractor with a cut sheet showing cut from top of hub stake to flow line of pipe. Contractor shall set batter boards at Intervals not to exceed SO feet, and shall care- fully check subgrade of trench, and flow line of pipe for proper grade and alignment. The pipe shall not vary more than 1/10 foot from true line and not more than 2/100 from the theoretical grade. Prior to laying, the pipe shall. be carefully Inspected for compliance with the specifications and pipe which is cracked or broken or that does not fully comply with the specifications shall be rejected, and Immediately removed from the site of the work by the Contractor. 118-1 ' i D. 111pe Joints: Clay pipe joints shall be Pre-Formed Compression Type joints conforming to ASTM Specification 0425-40T. These joints shall be "DICKEY FLEXIBLE COMPRESSION COUPLING" as manufactured by W. S. Dickey Clay Mfg. Co., "DELTA-SEAL" as manufactured by Texas Vitrified Pipe Company, or approved equal. Joints shall be installed In accordance with the manufacturers recommendation and the above ASTM Specification. E. Infiltration Precautions: It is not intended that an infiltration test be made on the completed pipe line. However, this Contractor will be expected to make all joints carefully so as to prevent the possibility of any appreci- able amount of water entering the Linn through the joints. During the jetting operation on the backfill, the line will be observed for possible leaks. In the event an appreciable amount of water appears to be leaking into the line, then a test would be required to determine whether corrective repairs should be made. This test would consist of ponding the backfill over the section of pipe in question, and measuring the amount of leakage downstream. The ponding would be to such depth so that the surface of the ponded water would be a minimum of 4 ft. above the flowline of the pipe, and the backfill saturated. The maximum allowable infiltration rate under this condition shall be 500 gallons per 24 hours, per mile, per Inch of diameter of the pipe. This test will not be required unless, in the Engineer's opinion, some faulty jointing or perhaps a broken pipe is clearly indicated. F. End Closure: During such periods of time when laying operations are not active, the ends of the pipe shall be tightly closed with a plug or bulkhead so that debris$ mud, and small animals will be prevented from entering the pipe.

Whore the character of the foundation materials is such that a proper Poumiation can-lot be obtained at the elevation in,lic:ttei by the plans, then, when directed vy the Engineer in wrltin;;, the !",unr.ractor shall der: pen the excavation to where a satisfactory rou rirtiurr can be utained. If the subgrade is sort, spongy, or disintej;^atod, the materials shall be removed until a firm, stable and uniforn, bearing is reached and the subgrad-, brought back to the requires grade with material compacted in place or with };ranular or concrote embedment material. If the unsatis- factory subgrade con•lition is lue to the tIontractor'a failure to make a proper provision for adequate drainage of excavations, kO')e expense of replacing any unsatisfactory subgrade shall be borne by the ^nntractor. However, if in tho opinion oi' thr Engineer, the unsatisfactory subgrade condition is not the result of the failure of th#. Contractor to provide adequate drainage, bailing or pumping facilities and the Engineer orders in writing that the Contractor rrccko al,lltionsl excavition and replace unsatisfactory subgrade material, then compensation will be made for the additional expense incurred. 4. Correcting Faulty Grader Any part of the trench excavation below grade shall be corrected with approved material, thoroughly compacted. Pipe Clearance in iRock_i Ledge rock, rock fragments, or unyielding shale or marl shall be removed to provide a clearance of at least six (611) Inches below all parts of the pipe, valves or fittings.

No blasting will be pc.-rinittei within three hundrol (30'') feet of any water wells or oil welly, nor within 40 feet of existing concrete cylinder water pipe line. 8. Bell holes ttequlre%l: Dell hole, of ample dim.resion shall be dug in trenches at each joint to permit the ,jointln;; to bu made properly and so th'it the pipe will rest on the full length of thu: brarrel, 9. Braced and Sheoted Trenches: Wherever nececr,ary to prevent caving e.rcavatlori shall be adequately sheeted and braced. Where sheeting and bracing a.•e used, the trench width shall be increased accordingly. Trench sheeting shall remain in place until the pipe has been laid, tested for defects, and repairet if necessary and the trench backfilled to a depth of two ( feet over the top of the pipe. 10. Care of Surface Material for He-Use: If local conditions permit their reuse, all surface materials suitable for reuse in restoring the surface shall be kept separate from the general excavation material. 11. Manner of Piling Excavated Materialt All excavated material shall be placed in a manner that will not endanger the work and will interfere as little as possible with public traffic, Roads and driveways must be kept open in every possible case, with exceptions to be made only upon permission from the Engineer. Drainage channels shall be kept clear of obstruction or other satisfactory provisions made for drainage. 12. Trenching by Machine or by Hands The use of trench digging machinery will be permitted except in places where operations of same will cause damage to existing structures above or below ground, in which case hand methods shall be employed. 13. open Trenchr The En„lneer shall have the right to limit the amount of trench wnich may be opened or partially opened at any time in advance of the completed lined and also the amount of trench loft not backfilled.

Protection of Existing Gtru trrres an,i Utilities: In the preparation of plans and specificatlons, the Engiucer has endeavored to indicate the location of all principal er.istint; urid~rr ruund lines which are known to the 3ngineer, No attempt h:rs Leon made to show minor lines or service lines, However, it is not guaranteed that all lints or structures have been shown on the Plans, Prior to the start of constructio,r, the Contractor shall communicate with the local rcpresentativo of the ail companies and utility companies, includint, tut not limited to the oil companies, gas company, telephon,-- company ail any other public aril private utility companies, and advise said represe,rtatives of the route of the proposed construction in order to obtain ti;e assistance of the utility companies in the location of and in the avoidance of conflicts with utility lines, i Where excavation endangers adjacent structures and utilities, the Con- tractor shall, AL his own expense, carefully support and protect all such structures and/ur utilities so that there will be no failure or settlement. Where it is necs~vsary to move services, pole:., guy wires, pipe lines, or other obstruetiuns, the contractor shell notify and cooperate with the utility owner. In case damtige to an existin, stricture or utility occurs, whether failure or sa tl merit, the Contractor shall restore the structure or utility to its original r,oniition ani position without compensation from the Owner. All costa of temporarily or permanently relocating, the conflictin; utilities :hall be borne by the Contractor without e,ctra compensation from the Owner. If, in the opinion of the Engineer, concrete backfill is necessary for the support of utility lines crossing trenches, the Engineer may direct 1500 lbs, concrete backfill be used. Payment will be made to the Contractor at the unit price bid for the installation of such quantity of the concrete backfill as directed by the Engineer. F.
