Wherever the term "or Equal" is used, it is understood to mean "Or Approved Equal".

The parties may agree upon one arbiter; otherwise, there shill be three, one named in writing by each party, and the third chosen by the two arbiters so selected, or if the arbiters fail to select a third within ten (10) days, he shall 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, the Engineer shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or informa- tion demanded in writing, the arbiters are empowered by both parties to take separate preceedings. The arbiters shall act with promptness. The decision of any two say 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 prece4ent to any right of legal action. The decision of the arbiter or arbiters may be filed in court to carry it into effect. The arbiters, if they deem the case demands it, are authorized to 17 - award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the appeal was taken without reasonable cause, they may award damages for any delay occasioned thereby. The arbiters shall fix their own compensation, unless otherwise provided by agreement, and shall assess the cost and charges of the arbitration upon either or both parties. The award of the arbiters must be made in writing. 7. ABANDONMENT Of CONTRACT I 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 others of the Engineer, 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 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 and payment bonds, 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, that where credit shall be allowed as provided for under Section b, Extra Work and Claims), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. Where there is no performance bond provided or in case the Surety should fail to commence compliance with the notice of completion hereinbefore provided for, within ten (10) days after service of such notice, then the Cvner may provide for completion of the work in either of the following elective manners: 7.011 The owner may thereupon employ such force of men and use such machinery, equipment, tools, materials, and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials, and supplies to said Contractor, and expense so charged shall be deducted and paid to by the owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract if the same had been 18 - ' I 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 Owwer; or 7.012 The owner, under sealed 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 same terms and conditions which are provided in this contract. In case of any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract such increase shall be charged to the Contractor and the Surety shall be and remain bound therefor. However, should the cost to complete any such new contract prove to be less than what would have been the cost to complete under this contract, the Contractor and/or his Surety shall be credited with the difference. When the work shall have beep: substantially completed the Contractor and his Surety shall be so notified and Certificatea, 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, 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 work shall be turned over to the Contractor and/or his Surety. Should the cost to complete the work exceed the con- tract 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 work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the Con- tractor 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 I - 19 - • I fifteen 115) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials, or pupplies 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 sales, 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 open to the Contractor and his Surety. 1.02 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 therefor from all machinery, tools, and equip- ment, and all materiels on the site of work that have not been included in payments to the Contractor and have not been wrought into the work. Aud 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. - 20 - SECTION I WATER DISTRIBUTION SYSTEM A.

H. LAYING PIPE After placing a length of pipe in the trench, the yarning materials for the joint shall be held around the bottom of the spigot so that it will enter the bell as the pipe is aboved into position. The spigot shall be centered in the bell and the pipe forced "home" and brought into true alignment. It shall be secured there with earth carefully tamped under and on each side of it, except- ing at the bell holes. Care shall be taken to prevent dirt from enter- ing the joint space. No blocking up of the pipe or joints will be per- mitted. Whenever it is necessary to deflect pipe from a straight line, either in the vertical or horizontal plane, to make small angles in alignment to avoid obstructions, to plumb stems, or for other reasons, the degree of deflection shall not exceed that shown by the Handbook of the Cast Iron Research Association. Although the above section applies primarily to bell and spigot pipe, all applicable portions apply as well to roll on and mechanical joint pipe. 1. FIRE HYDRANTS Fire hydrants shall conform to Smerican Water Works Association Specifications, C-502-54. Hydrants will have a five anri one-forth (5k) inch valve opening and two, two and one-half (2h) inch steamer connections.

A one and one-forth (1k) inch pentagon operating nut shall open to the left. Each hydrant will be preceeded by a gate valve. Fire hydrants shall be Mueller (A24015) (Traffic Model). SETTING FIRE HYDRANTS. GATE VALVES. AND SERVICE BOXES Fire hydrants, gate valves and valve boxes installed in trenches, shall be placed where required. They shall be set plumb and the valve boxes shall be directly over the valves. After being correctly positioned, earth fill shall be carefully tamped around the service box for a die- Lance of four feet on all sides of the box. Each service box shall be set in a concrete pad, two feet square mad eight inches thick at ground elevation or as Airected by the City of Denton. Fire hydrants shall be set at such elevations that the connecting pipe and the distri- bution mains shall have the same depth of cover. Each fire hydrant shall be placed upon a slab of concrete not leas than four inches thick and fifteen inches square. The backside of the fire hydrant opposite the pipe connection, shall be blocked with concrete to prevent the fire hydrant from blowing off the line. Care must be taken in placing of the concrete not to block the weep holes at the bottom of the fire hydrant. Around the base of each fire hydrant shall be placed not leas than seven s - 23 - cubic feet of broken stone or loose gravel and rock to insure the com- plete drainage of the fire hydrant when closed. All backfiil after installing any fire hydrant shall be thoroughly compacted to tt,e surface of the ground. Before installing any fire hydrant or gate valve, care shall be taken to see that all foreign material is r:stmoved from the barrel. Stuffing boxes shall be tightened and the fire hydrant or gate valve opened and closed to see that all parts are in working condition. J. SERVICE LINES AND TAPS Service line on Oak Street and McKinney Street only will be tied to the new water line. A service tap shall be made where designated on plans. The tap shall be a minimum of 3/4 inch (or at specified), and shall be made by drilling and tapping the main for the inslirtion of a corporation stop (Mueller H15000 or equal).

EXCAVATION Trenches shall be excavated by a trenching machine except in locations where hand trenching is required. The banks of trenches shall be vertical. Trenches will be excavated to the lines and grades laid out by the Engineer or as shown on the plans. The width of the trench shall be six (b) inches vinimum and eight (8) inches maximum on each side of the pipe bell. Trenches for water pipe shall be carried to a depth necessary to obtain a minimum cover of three feet six inches (4211) over the pipe as measured from the proposed street surface. The excavation shall not advance more than five hundred (500) feet ahead of the completed backfilled line. Pipe shall be laid in all trenches that have been opened at the end of each day's work, unless the Contractor secured written permission to do otherwise from the Engineer. 24 - s, , 1. If the bottom of the trench becomes an undtable foundation for the pipe through the neglect of the contractor to adequately shore or dewater the trench, or if the undisturbed material encountered at the grade depth constitutes, in the opinion of the Engineer, an unstable foundation for the pipe, the contractor will be required to remove such unstable material and backfill the trench to the proper grade with approved compacted gravel. 2. Also, if the trench is inadvertently excavated deeper than necessary, it shall be backfilled to the proper grade with approved compacted gravel at the contractor's expense. The contractor shall remove any water which collects in the trenches while water pipes are being laid. In no case shall water, be allowed to run through the pipe. Water encountered shall be disposed of by the contractor in a manner satisfactory to the Engineer. The bottoms of the trenches for all pipe shall be carefully and truly graded, formed and lined according to the grades and dimensions furnished by the Engineer before any pipe is laid therein. Sell holes shall be excavated by hand. The contractor shall excavate all trenches, including work necessary in working around existing pipe lines or other obstructions. The con- tractor shall give notice to the owners of any such lines of obstructions in order that they may have time to take the necessary precautio " for protecting their protecting their property. The contractor shall be responsible for protecting the owner from any damage from his operations in such work. In rock, excavation shall be carried four (4) inches below the bottom of the pipe and loose earth or gravel, thoroughly tamped, shall be used for backfilling to grade. After testing and inspection of pipe lines have been finished on any completed portion of the work the trench may be backfilled. Back- filling shall be accomplished in compliance with the applicable portions of these specifications. L. BACKFILLING - Good sound earth from the spoil band shall be brought up in hand or mechanical tamped layers not exceeding six (6) inches in thickness of loose fill approximately equal on each aide of the pipe to a height of 12 inches over the top of the pipe. The tamping shall be done in such a manner as not to disturb the pipe from its original position. The backfill material may need to be moistened to facilitate compaction. This determination will be made by the Engineer. - 25 - 1. BACKFILL FOR CROSSING LOCUST STREET AND BELL AVENUE (Type A) - The backfill up to 12 incheb above the pipe shall be as specified in the above Section L. From that point to two inches below the pavement, the trench shall be brought up in layers not exceeding eight inches loose fill of cement stabilized road gravel. This road gravel must have a P. I. of ten (10) or under and at least 8% Portland Cement added to it by weight. Each layer shall be tamped with a mechanical tamped and the material shall be moistened to facilitate compaction and hydradation of the Cement. The areas in which this backfill will be required are those designated on the plans as Type A backfill. Surfacing shall be as called for in the following section. 2. BACKFILL FOR ALL OTHER AREAS (TvDe B) - The backfill up to 12" above the pipe shall be as specified in Section L. The remainder of the backfill material shall be placed loosely in the trench up to the top of the ditch. The trench shall then be thoroughly jetted with water under pressure until all settlement has ceased. The trench shall then be mechanically tamped with a hydro hammer. No rock greater than six (6) inches in any direction may be placed in the final backfill. After tamping a 12" layer of 2:27 pitrun sand and gravel, and Portland Cement shall be placed in the ditch. This back- fill shall be throughly tamped to achieve at least 95% of standard proctor. As soon as possible, a two inch thickness of hot mix surfacing conforming to Texas Highway Department Specifications for Type D mix shall be placed where designated on the plans. In concrete areas, a 6 inch thickness of concrete shall be placed. The contractor shall keep all ditches well maintained during construction filling all depressions as they occur. In the areas on McKinney Street and Oak Street marked for type C backfill the requirements for the tamping of the ditch and the stabilized gravel backfill will be waved. M. CONNECTION TO EXISTING WATER MAINS A. Description - Where indicated on the plans ,nd/or here- inafter specified, the Contractor shall connect the new main with existing mains or lines. This will be accomplished in the manner essentially shown or specified. The Contractor shall furnish all labor, materials, equipment, and services required for the locating and uncovering of the existing lice, the making of cuts in the existing line, the removal, relocation and/or lowering of existing lines as required, de-watering of the trench, connecting of the existing line into the new main and any and all appurtenant work required for a complete connection. Re- located mains or lines shall be laid so that all valves so re-located or installed shall be set vertically. - 26 - Only such connections to existing mains as are necessary to load, test and sterilize mains under construction with water from city mains will be permitted prior to the sterilization of new mains. All other connections to existing mains from a new main being constructed shall be made. Contractor will be required to install flanged gate valves or otherwise plug and block lines, crosses, tees or other fit- tings installed in the new main to permit testing and sterilization prior to the making of connections. Such plugs and blocking shall be adequate to withstand a test pressure of 150 pounds per square inch. No blocking will be required from flanged gate valves. Where cut-ins are made immediately adjacent to valves which are under pressure, the Contractor shall take all necessary precautions to brace such valves with temporary blocking and bracing which shall be of ample size and properly placed to prevent movement or blowing off of any pipe, valves or fittings due to water pressure on the main. Connections to existing water mains shall be made at the loco- tioas shown, as specified and/or as directed by the Engineer. All such connections shall be made in a most expeditious add workmanlike mminer to cause the least inconvenience to water customers and to traffic, and shall be made at night unless otherwise approved by the Imlineer. The detailed schedule of operations for making each connec- tilins shall be approved by the Engineer before any work thereupon is commenced. N. it CONCRETE BACKING Concrete having compressive strength of not less than 1500 pounds per square inch shall be used as a cradle or backing where shown on the plans or where directed by the Engineer. All materials including aggregates, cement, and water, as well as the mixing and placing of the concrete, shall be approved by the Engineer. Bends of 22k degrees and greater, plugs, and all tees, crosses, etc., shall be backed with concrete as a thrust backing. Backing shall be placed between solid ground and the fitting to be anchored; the area of bearing on pipe and on ground in each instance shall be that required by the Engineer. The backing shall, unless otherwise directed, be placed so that the pipe and fitting joints will be accessible for repair. Concrete shall be composed of normal Portland Cement, coarse aggregate, fine aggregate, and water proportioned and mixed properly in a concrete mixer. Transit mix concrete will be allowed, Portland Cement shall by Typ42 and shall be fully protected until incorporated in this work. Gravel to be used for coarse aggregate shall consist of clean, hard, durable rains, and shall be free from an excess of salt or alkali and fore materials. Concrete shall have a compressive strength of not less than 1500 pounds per square inch at twenty-eight (28) days and shall have not less than three (3) sacks of cement nor more than six and three-fourths (b 3/4) gallons of water per cubic yard of concrete. ~I 27 - 2. CONCRETE FOR PAVEMENT REPLACEMENT Concrete for pavement replace- ment shall follow all requirements called for in the above Section I except the concrete shall have a compressive strength of not less than 3000 pounds per square inch at twenty-eight days and shall have not less than five sacks of cement per cubic yard of concrete. i 0. TESTING WATER MAINS All pipe lines shall be tested under pressure of 150 pounds. Where practicable, pipe lines shall be tested in lengths between line valves or plugs of no more than 1,500 feet. Duration of test shall be not less than two (2) hours where joints are exposed and not less than twenty-four (24) hours where joints are covered. All visible lea'ka at exposed joints and all leaks evident on the surfaco and covered shall. be recaulked or reassembled and mini- mized regar1less of f:he total leakage as shown by test. All pipe, fittings and oth.r materials found to be defective under test shall be removed and replaced at the contractor's expense PEWSSABLE LEAKAGE No pipe installation will be accepted until the leakage is less than the number of gallons per hour as determined by the following formula: ndv Ln P 1,850 Where L equals the allowable leakage in gallons per hour; H equals the number of joints in the length of pipe line tested; D equals the nominal didmeter of the pipe in inches, and P equals the average test pressure in pounds per square inch. Based on this formula the permissible leakage per 100 pipe joints per hour is as follows: PERMISSIBLE LEAKAGE PER 100 PIPE SIZE JOINTS IN GALLONS PER HOUR 2" 1.33 41' 2.65 6" 3.91 see S. 10" 30 6.62 12" 14" 7.94 9.27 16" 10.59 - 28 - VARIATION FROM PERMISSIBLE LEAKAGE Should any test of pipe in place disclose leakage greater than the specified, the contractor shall at his own expense locate and repair the defective joints until the leakage is within the specified allowance. LEAKAGE DEFINED Leakage is defined as the quantity of water supplied into the newly laid pipe, or any valved section of it, necessary to maintain the specified leakage test pressure after the pipe has been filled with water and the air expelled. P. STERILIZATION OF WATER MAINS Each unit of completed water line installed shall be thoroughly sterilized with chlorine or hypo- cholrite before it is placed in operation. The amount of chlorine applied shall be such as to provide a dosage of not less than fifty (30) parts per million. The chlorination material shall be introduced to the water line in such a manner as to distribute the chlorine to throughout the oyster.. All valves in water lines being sterilized shall be opened and closed several times during the twenty-four (24) hour period. Following a contact period of not leas than twenty-four (24) hours, the sterilizing solution shall be discharged from the pipe and replaced with City Water direct from a City Main. A sample of water from the sterilized main shall be taken (not through a fire hydrant) from a suitable tap under the supervision of the Engineer or his Inspector and submitted to the City Chemist or the State Health Deportment for:analysis. If the test shows a satisfactory quality of water, the line so sterilized may then be placed in service. If the sample shows unsatisfactory quality of water, the process of steriliza- tion shall be repeated until a satisfactory water is obtained. - 29 - SECTION II CONCRETE CYLINDER PIPE AND FITTINGS A.

Proper implements, tools, equipment and facilities shall be provided and used by the Contractor for the safe and convenient prosecution of the work. All pipe, fittings, specials, valves, etc., shall be lowered into the trench by means of a "side boom", crane and other suitable machine and not be rolled or dumped into the trench. The "side boom", crane, etc., shall be of a sufficient size for handling the pipe, shall lift and lower the pipe at a slow rate of speed, and shall be capable of stopping the lifting operation at any point without producing a shock or otherwise jerking or vibrating the pipe. The hoisting cable pipe clamp shall be connected to the pipe in such a manner to prevent damage to the coating. The method of connection shall be subject to the Engineer's approval. Before lowering into the trench, each joint of pipe shall be inspected and any unsound or damaged pipe shall be rejected. The pipe shall be kept clean during the laying operation and free of all sticks, dirt and trash, and at the close of each operating day the open end of the pipe Shall be effectively sealed against the entrance of all objects and especially water. No pipe shall be laid in water, or when the trench conditions or the weather is unsuitRble for such work, except in an emergency and then only upon permission of t-.he Engineer. All pipe shall be laid accurately to established lines and grades; with valves and fittings at the required location, and with joints centered - 32 - • r i and spigots home. Line and grade stakes will be provided by the Engineer. C. Pipe Jointfa - General: Before laying each joint of pipe, the bell and spigot rings shall be thoroughly cleaned by brushing and wiping. If any damage to the protective costing on the metal has occurred, it will be required of this Contractor to repair such damage before the pipe is laid. The damaged areas shall be thoroughly cleaned and immediately following the cleaning the metal shall be painted with the same material used originally in the manufacture of the pipe. Sections of pipe shall be tightly fitted together and care shall be exercised to secure true alignment and grade. Where pipe is being laid tae gasket shall be placed on the spigto ring and the spigot end of the pipe shall then be entered into the bell of the adjoining pipe and forced into position. The gasket and the inside surface of the bell shall be lubricated with a suitable solution (flax soap) which will f%cilitate the telescoping of the joint. The inside joint recess between ends of the pipe sections shall have a maximum and minimum width of three-quarter inch (3/411) and one'half inch respectively. No "Blocking up" of pipe or joints will be permitted. D. Interior Joints: Just prior to the making of the joint, the bell end of the pipe shall be "butter" with sufficient grout to completely fill the inside joint recess when the joint is made. The spigot shall then be • telescoped into the bell. The interior shall be thoroughly swabbed and cleaned. The concrete mortar shall consist of one part of cement to two parts of sand. Cement shall comply with ASTM Specification C-150, Type i. The sand shall conform to ASTM Specification C144. Careful inspection shall bt made of every joint to insure a smooth continuous interior surface. The interior of the pipe shall be thoroughly cleaned and any obstructions removed that may reduce its carrying capacity. Following completion of pipe lf.ne progressively or in sections, including completion of inside joints and inspections, insofar as might be possible or practicable, the line shall be kept filled with water. k. ~ E. Exterior Joint: The exterior joint shall be made by placing a burlap joint wrapper around the pipe which will be held in place by means of two straps. The burlap wrapper shall be seven (111) inches wide and hemmed on each side. The burlap cloth shall be of such length that it will encircle the pipe, leaving enough opening between the ends to allow the mortar to be poured inside the wrapper. The wire straps shell be of sufficient length to encircle the pipe and securely fasten the wrapper to the joint. The burlap wrapper shall be similar and Equal to those manufactured by Mar-Mac Manufacturing Company. The grcup used for pouring the joint shall consist of one part Portland Cement, ASTM Spec. C-1500 Type I, to two parts of clean, fine sharp (plaster) sand, conforming to ASTM Specification C144 and mixed to the consistency 33 - • of thick cream. The joint shell be filled with this grout from one side in one continuous operation until the grout has flowed entirely around the pipe. During the filling of the joint, it shall be nodded with flexible wire to settle the grout. F. Piotection of Exposed Metal: All exposed metal shall be protected by a minimum one (1") inch coating of Portland Cement mortar consisting of one part c#jrent and two parts sand. Exposed surfaces such as, but not limit- ed to, flanges, caulked joints, threaded outlets, closures, etc., shall be protected in this manner. Where necessary, coating shall be reinforced with wire mesh. The surface receiving a cement mortar coating shall be thoroughly cleaned and wetted with water just prior to placing the Eement mortar coating. After placement, care shall be taken to prevent cement mortar from drying out too rapidly by covering with damp earth or burlap. Cement mortar coating shall not be applied during freezing weather. i For large diameter flanges where it is impracticable to use a cement mortar coating, and where directed by the Engineer, two (2) coats of "Bitu- mastic 30' as manufactured by the Koppers Company, or approved equal, may be used. "Bitmastic 30" shall be applied in accordance with the manufacturer's recommendations. G. Patch: Excessive patching of lining or coating will be permitted. Patching of lining or coating will be allowed whe m area to be repaired does not exceed 100 square inches And has no dimensions greater than 12 inches. In general, there shall not be more than one patch on either the lining or the coating of any one joint of pipe. Whore necessary to patch the pipe, patch shall be made with a mortar of one part Embeco (as manufactured by the Master-Builders Company), one part Portland Cement and one part clean, sharp sand; all measurements to be by weight. Pipe thus patched shall not be installed until the patch has been properly and adequately cured andsunless approved for laying by the pipe manufacturer's inspector and by the Engineer. H. Manufacturer's Representative; Attention is directed to the provision of the Specifications relative to manufacturer, etc., of the pipe wherein it is required that a factory trained, qualified, job-trained inspector b:, placed on the job. No pipe shall be laid unless such inspector is present and inspects the laying of the pipe. - 34 - . I SECTION IY __INSTALLING CAST IRON PIPE AND FITTINGS A. Descrit,tion: Cast Iron pipe, fittings, specials and valves are to be installed at locations shown on plans and specified in these Contract Docu- ments. Unless otherwise indicated, pipe in trenches shall be laid to the grade shown or an even grade from point to point for which elevations are furnished. Attention is called to the fact that the Engineer will set grades for pipe laying at 100-foot intervals as specified under "Cover Over Top of Pipe Barrel". All of the requirements of the specifications under the section, "Ex- cavation and Backfill", govern for the excavation of trenches for laying concrete cylinder pipe, fittings and specials, backfilling,etc. B. Pipe Handling: All pipe, fittings, special castings and gate valves shall be lowered into trench by derrick, tripod, crane or other suitable machine and shall not be rolled in or dumped into the trench. Pipe, fittings and valves shall be handled in such a manner as not to damage the coating. Before lowering and while suspended, each piece of pipe shall be rung with a light hammer to detect flaws, and any unsa,nd pipe shall be rejected. All dirt and trash that may be in the barrel of the pipe, on the spigot and/or in the bell shall be removed while the pipe is suspended, All pipe and fittings shall be handled and lowered into the trench with slings. The use of hooks for handling pipe and fittings will not be permitted. Where it becomes necessary to deflect the pipe to avoid obstruction, she deflection of each joint must be approved by the Engineer. The pipe is to be kept clean during the laying o oration and free of all wticks, dirt and trash, and at the close of each operating day the open end of the pipe is to be effectively sealed against the entrance of all objects and especially water. Unless otherwise specified or unless otherwise directed by the Engineer, the joints for all bell and spigot cast iron pipe, fittings and specials shall be made, using lead and/or mechanical joint for jointing materials and/or "Tyton Joint" (or similar joint). C. Joint M k_ jt: 1. Jointinit Mechanical Joint Pipe: This type pipe shall bs jointed in full accordance with the manufacturer's recommendations and shall be done in a neat and workmanlike manner. Care shall be taken to prevent shearing the bolts. The jointing of the pipe shall be done as follows, unless otherwise directed by the Engineer. (a) After carefully cleaning both spigot and bell and after slipping the follow :lag and the gasket over the spigot end, the spigot shall be i4 ipped into the bell. -35- • (b) If requested by the Engineer, a lubricant shall be applied to the spigot to assist in assembly. (c) The gasket shall be carefully seated by hand so as to be even in the bell at all points. (d) After drawing up the follow ring to uniform bearing against the gasket, the bolts are to be inserted and tightened by hand in pairs using bolts opposite each other. (e) The nuts are to be tightened amply to hold the required pressure, Extension wrenches, or pipes over wrench handles, will not be permitted. Ten (10") inch ratchet wrenches shall be used to tighten the nuts, unless other type wrenches are approved by the Engineer. The finished joint shall be neat and uniform and shall be watertight. 2. Makinit Flanged Joints: The Contractor shall be responsible for the measurement of all connections. Flanged piping shall be erected in accordance with the controlling dimension shown on the Plans. Each piece of flanged pipe shall be thoroughly cleaned to remove dirt, rust, grease, and other foreigh matter, and flanged faces shall be thoroughly wire brushed to insure even bearing for gaskets and mating flanges. Gaskets for flanged joints shall be composition sheet-packing, full faced, factory cut, of one- ' sixteenth (1/1611) inch thickness, "Cranite", or approved equal. Flange bolts shall be installed with bolts in one direction. Flange bolts shall be tightened, each in turn, at a uniform rate around the joint. 3. Making "Teton" and/or "Fast-Tits" Joints: The jointing of this type of joint shall be as recommended by the manufacturer. The pro- cedure for jointing shall be generally as follows: (a) The spigot and socket shall be thoroughly cleaned and dried before starting the assembly of the joint. The gasket seat in the socket and the gasket shall be wiped with a cloth. (b) The gasket shall be placed into the seat in the socket. (c) A thin film of lubricant shall be applied to the inside surface of the gasket that will come in contact with the entering pipe spigot. • (d) The spigot shall have a film of lubricant, if necessary. (a) The joint shall be made by exerting sufficient force on the entering pipe so that its plain end will move pest the gasket. The exerting force may be by use of the "crowbar method", (8" and smaller); "fork-tool method", (811 and smeller); yr "jack method", (10" and larger). END OF SECTION • 36 - • SECTION V - HANDLING AND INSTALLING GATE VALVES A. Handlinit and Installing Gate Valves; Valves shall be carefully handled and lowered into position by mechanical equipment in such manner as to prevent lamage to any part of the valves. The valve shall be placed in proper position with stem truly vertical or horizontal as the case may be, and shall be securely held until all connections have been made. Valve shall rest on a concrete pad. After the valve box is in place, backfill material shall be firmly tamped around the outside so as to hold the box in propet position. The top of the box shall be adjusted to the proper elevation and securely held in place. B. Blocking Under Gate Valves; All gate valves which are buried shall rest on concrete pad. Pad shall extend for the full width of the trench and from back of hub (or flange). Care shall be taken not to interfere with the jointing. Concrete shall be of 1300 p.s.1. quality. END OF SECTION 37 - SECTION VI -HYDROSTATIC TEST A. General: After the water line has been 1'id and backfilled, each • valve section of newly laid pipe shall be subjected to a hydrostatic pressure test. For any section being tested, the pressure applied shall be such that at the lowest point in the section, the pressure shall be 150 lbs. per square inch. Adjustments aserequired shall be made for differential in elevation between the low point of the section being tested and center line of pressure test gauge. B. Duration of Test: The duration of each pressure test shall be four (4) hours. C. ProcedureTi-The Contractor may test the concrete cylinder pipe line in sections when all the pipe in the section is at least 28 days old. The cast iron pipe line and/or the asbestos-cement pipe line may be tested upon com- pletion of backfilling and the "setting up" of concrete blocking. The test shall be made against valves when available, or by placing temporary bulkheads in the pipe, and filling the line +lowly with water. Cara 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 pressure for at least 48 hours to allow the lining to absorb what water it will and to allow the escape 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 of bulkheads, provision shall be made for measureing 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 the air from high points other than where air valves 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. D. Easmination Under Pressure: During the last two hours of the teat, 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 be removed and replaced with sound material in the 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. - 38 • E. Permissible Leakage: No pipe installation will be accepted until or unless the leakage, as determined by this Hydrostatic Test, is with the allowances set forth in the tabulation below: Pipe Size Allowable Leakage per 100 Joints Gallons per hour 2" 1.33 4" 2.65 6" 3.97 8" 5.30 10" 6.62 12" 7.94 16" 10.59 18" 11.92 20" 13.24 F. Variation from Permissible Leakage: Should any test of pipe laid dis- close leakage greater than that specified, the Contractor shall at his own expense locate and repair the defective points until the leakage is within the specified allowable. G. Leakage Defined: Leakage is defined as the quantity of water to be supplied into the newly laid pipe, or any valved section of it, necessary to maintain the specified leakage test pressure after the pipe has been filled with water and the air expelled.
