He shall interpret all provisions in the Plans and Specifi- cations; decide all questions as to the acceptable fulfillment of the contract on the part of the Contractor; and decide all questions as to claims and com- pensation. All instructions, rulings, and decisions of the Engineer shall be in writing and shall be final and binding on all parties unless formal protest is made as provided in the following paragraph. If the Contractor considers any work demanded of him to be outside the requirements of the Contract, or if he considers any instruction, ruling, or decision of the Inspector or Engineer to be unfair, he shall, within ten (10) days after any such demand is made, or instructions, ruling or decision is given, file a written protest with the Engineer, stating clearly and in de- tail his objections and the reasons therefor. Except for such protests and objections as are made of record in the manner and within the time above stated, the Contractor shall be deemed to have waived and does hereby waive all claims for Extra Work, damages, and extensions of time on account of demands, instructions, rulings, and decisions of the Engineer.

Upon receiving notice of such suspension, the Contractor shall discontinue said work, or such parts of it as the Board may designate. Upon such suspension, the Contractor's control shall terminate, and thereupon the Board or its duly authorized representative may take possession of all or any part of the Contractor's materials, tools, equipment, and appliances upon the premises, and use the same for the purpose of completing said contract, and hire such force and buy or rent such additional materials and supplies at the Contractor's expense as may be necessary for the proper conduct of the work and for the completion thereof; or may employ other parties to carry the contract to completion, employ the necessary workmen, substitute other machinery or materials, and purchase the materials contracted for, in such manner as the Board may deem proper; or the Board may annul and cancel the contract and relet the work or any part thereof. Any excess of cost aris- ing therefrom over and above the contract price will be charged against the Contractor and his sureties, who will be liable therefor. In the event of such suspension, all money due the Contractor or retained under the terms of this contract shall be forfeited to the Board, but such forfeiture will not release the Contractor or his sureties from liability for failure to fulfill the contract. The Contractor and his sureties will be credited with the amount of money so forfeited toward any excess of cost over and B116 - C18 - above the contract price, arising from the suspension of the operations of the contract and the completion of the work by the Board as above provided, and the Contractor will be so credited with any surplus remaining after all just claims for such completion have been paid. On the completion of the contract, the original contractor shall be entitled to the return of all his unused materials, and his equipment, tools and appliances, except that he shall have no claim on account of usual and ordinary depreciation, loss, and wear and tear. In the determination of the question whether there has been any such non-compliance with the contract as to warrant the suspension or annulment thereof, the decision of the Board shall be binding on all parties to the con- tract. (g) Right-of-Way - The right of way, as shown on the plans, for the work to be constructed will be provided by the Board. The Contractor shall make his own arrangements, and pay all expenses for additional area re- quired by him outside of the limits of right-of-way. (h) Removal of Utilities - In case it shall be necessary to remove any railroad tracks, poles, standards, hydrants, gas pipes, water pipes, electrical conduits, tubing or underground structure of any character, or any portion thereof, the owner or owners, or their agents or superintendents shall, upon proper application by the Contractor, be notified by the Engineer to remove the same within a specified time. All costs of protecting, supporting, altering, removing, and reinstal- ling pipes, poles, structures, trees and other obstructions, shall be borne by the Contractor. The Contractor shall not interfere with said tracks, poles, standards, hydrants, gas pipes, water pipes or other underground structures, or any portion thereof, until after the expiration of the time specified. It is not contemplated that utilities, not conflicting with the function of the structures to be built under the contract, will be required to be moved to facilitate the use of mechanical construction equipment. The location and grades of underground pipes and structures shown on the plans, for the benefit of the Contractor, have been obtained from the office records of the utilities concerned and the Board assumes no respon- sibility for their accuracy. In cases where underground pipe or concrete structures in use, not depicted in any way on the plans or in the specifications, are disclosed in the operations, the Contractor shall immediately notify the Engineer in writing. The Engineer will evaluate, in writing, the determination of the Contractor's responsibility in regard thereto and the method for removal of the obstacle or modification of the pipeline. B116 If extra work is involved in such removal or modification, the perti- - C19 - nent sections of these specifications shall apply. This determination does not apply to any pipe or concrete structure shown on the plans, even though not shown in their accurate positions. Rock and/or broken concrete found in the excavation shall be removed at the Contractor's expense. (i) Right of Access to Street - The right is reserved to the County, City, State, and the Board, and also to street railroads, water, gas, electric, telephone and telegraph companies to enter upon the street for the purpose of making repairs, changes and new installations that have become necessary by the improvement.thereof, or for necessary maintenance. (j) Extent of Street to be Opened Up - Trenching for and laying of pipe, shall be coordinated to conform to the City, County and/or State permits for same where such work is under permit. In easements or rights- of-way, other than above, trenching shall be coordinated with the pipe laying so that excavated, but not backfilled, trench shall be kept to a minimum. On all backfilled trenches subject to vehicular travel repavement shall be accomplished in accordance with the applicable sections of the special conditions immediately after backfill is accomplished, if permitted. C-9 MEASUREMENT AND PAYMENT (a) Measurement for Pay Quantities - Payment for work done will be made in accordance with measurements of the completed work made by the Engineer. Materials paid for by the ton, except as otherwise provided in these specifications, shall be weighed in trucks or railroad cars on public or private platform scales. The scales will carry a certificate issued by the Department of Weights and Measures of Orange County certifying to their accuracy. All such material shall be weighed in the presence of a represen- tative of the Engineer or other agent so designated, who shall immediately be given a record of weight of material. A slip giving the weight of the material in truck shall also be given the driver of truck to hand to the Board Inspector on the job as soon as the truck arrives at the work. All trucks or railroad cars used for this hauling shall be weighed empty at such times as directed by the Engineer. (b) No Payment for Temporary Works - No direct payment will be made to the Contractor for providing transportation, light, power, tools, and equipment, or for furnishing, building, and_ maintaining camps, construc- tion plant, access roads, sanitary conveniences, disposal works, water supply, fire protection, guards, trestles, telephone system, and other tem- porary structures, plant, and materials, or for medical attendance or health protection, or for watchmen, magazine keepers or guards, or for any other service, thing, or material, unless payment therefor has been definitely provided. Compensation for all such services, facilities, things, or materials necessary or required to execute the work in accordance with the provisions of the contract shall be considered as having been included in the prices stipulated for the appropriate items. B116 - C20 - (c) Partial Estimates - In order to assist the Contractor to pro- secute the work advantageously, the Engineer will, on or about the twenty- fifth day of each calendar month, excepting as provided in Paragraph (d), make in writing and certify to the West Orange County Water Board an es- timate such as in his opinion will be just and fair, of the amount and value of the work done by the Contractor up to that time in the performance of the contract. In the case of work for which unit prices are named in the con- tract the estimate shall be computed on the basis of said unit prices or per- centages thereof. In the case of work for which a lump sum is named in the contract, the Engineer may use the prices submitted by the Contractor in the "Bidders Proposal"; provided, that in case the prices submitted in said breakdown do not in the opinion of the Engineer truly represent the actual relative costs of the different parts of the work, the Engineer shall prepare a schedule of prices which shall be used in estimating the value of the work performed; and provided further, if the Contractor was .not required to submit such breakdown with his bid, the Engineer shall prepare a schedule of prices which will be.used in estimating the value of the work performed. To the figure thus arrived at shall be added any amounts due the Contractor for extra work and the amount of any approved claims for extra cost to the date of the progress estimate. A deduction of 10 percent or of such larger or smaller percentage as may be hereinafter stipulated in these specifica- tions shall be made from the total thus computed, and from the remainder there shall be further deducted any amounts due the Board from the Contrac- tor for supplies or materials furnished or services rendered and any other amounts that may be due the Board under the terms of the contract. From the balance thus determined shall be deducted the amount of all previous payments and the remainder shall constitute the partial estimate for that month. Unless otherwise specifically provided in the Detail Specifications, materials not incorporated in the work and none of the Contractor's plant shall be included in the partial estimates. Such partial estimates shall not be required to be made by strict measurement, but they may be made by measurement or by estimation, or partly by one method and partly by the other, and it shall be sufficient if they are approximate only. No allowance in partial pay estimates will be given for pipe delivered to the job site, but not layed in_accordance with these specifications. (d) Partial Estimates May Be Withheld - The partial estimates pro- vided for in Paragraph (c) hereof and/or the payment thereof may, at any time, be withheld or reduced if, in the opinion of the Engineer, the Contrac- tor is not diligently and efficiently endeavoring to comply with the intent of the contract, or if the Contractor shall fail to pay his labor and material bills as they become due. (e) Partial Payments - (1) Upon each partial estimate being made and certified in writing to the West Orange County Water Board, the Board (un- less payment be withheld as provided in Paragraph (d) hereof) within 15 days after the date of such estimate, except as stipulated in subsection (b) hereof, shall pay to the Contractor .the amount stated in such estimate or certificate to be due the Contractor; provided, however, that the Board may at all times reserve and retain from such partial payments, or any of them, in addition B116 to the retained percentage and other amounts above mentioned to be deducted - C21 - I in computing the partial estimates, any sum or sums which by the terms hereof, or of any law of the State of California it is or may be authorized or required to reserve or retain; and provided further, that no such partial estimate or payment shall constitute an acceptance ol the work or any por- tion thereof. The percentage deducted as above set forth shall become due and payable with and as a part of the final payment to be made as herein- after provided. (2) In the event work under the contract or any part there- of shall be discontinued as provided in Section C-8 (f), the said retained percentage shall become and be the property of the Board to the extent necessary to repay to the Board any excess in the cost of the work above the contract price; and after issuance of notice to discontinue work, as therein provided, no payments upon partial estimates or otherwise shall thereafter be made the Contractor for the work covered by said notice until completion of the work and final settlement. (f) Final Estimate and Payment - Whenever in the opinion 'of the Engineer the Contractor shall have completely performed the contract on his part, the Engineer shall so certify in writing to the Board, and in his certificate he shall state, from actual measurement, the total amount of work done by the Contractor, and also the value of such work under and according to the terms of the contract. Within 10 days after the date of acceptance by the Board, the Engineer will cause to be filed, on behalf of the Board, in the office of the county recorder of the county or counties in which the work is located, a notice of the completion of the work herein agreed to be done by the Contractor. On the expiration of 35 days after the filing of such notice of completion of the work, the Board shall pay to the Contractor the amount remaining after deducting from the amount or value stated in the first-mentioned certificate all such sums as shall theretofore have been paid to the Contractor under any of the provisions of the contract, and also any sum or all sums of money which by the terms hereof the Board is or may be authorized or required to reserve or retain. All prior certifi- cates upon which partial payments may have been made, being merely esti- mates, shall be subject to correction in the final certificate, which final certificate may be made without notice thereof to the Contractor or of the measurements upon which it is based. It is mutually agreed between the parties to the contract that no cert'_- ficate given or payment made under the contract, except the final certificate of final payment, shall be conclusive evidence of performance of the contract, either wholly or in part, against any claim of the party of the first part, and no payment shall be construed to be an acceptance of any defective work or improper materials. _ And the Contractor further agrees that the payment of the final amount due under the contract, and the adjustments and payment for any work done in accordance with any alterations of the same, shall release the Board, and the Engineer from any and all claims or liability on account of work performed under the contract or any alteration thereof. (g) Extra and Force Account Work - Extra work as hereinbefore de- fined, when ordered and accepted, shall be paid for under a written work B116 order in accordance with the terms therein provided. Payment for extra - C22 - work will be made at the unit price or lump sum previously agreed upon by the Contractor and the Engineer, or by force account. Where payment is to be made on a force account basis, the Contrac- tor shall receive the actual cost of all materials, labor and rented equipment furnished by him as shown by his paid vouchers, plus fifteen (15) percent. For the use of equipment owned by the Contractor he shall be paid the current prices prevailing in the locality, which shall have been previously determined and agreed upon in writing by the Engineer and by the Contractor. All extra work and force account work shall be adjusted daily upon report sheets, furnished to the Engineer by the Contractor and signed by both parties, which daily reports shall thereafter be considered the true record of force account work done.

EXCAVATION (a) General - Excavation shall include the loosening, loading, re- moving, transporting, depositing and compacting in final location of all materials, wet and dry, necessary to be removed for purposes of construc- tion, the furnishing, placing and removing of all sheeting and bracing, all pumping and drainage of excavation, the supporting of structures above and below the ground, the supporting and responsibility for all pipe or pipelines or other utilities which may be encountered, the handling of all water encountered in the excavations, all backfilling around and under structures and backfilling of all trenches and pits and all other incidental work as shown on the plans and as specified. All excavation removed shall be disposed of in the fill areas and under and around the structures as shown on the plans, and as specified herein or shall be wasted or disposed of as directed by the Engineer. (b) Character of Material - The Contractor must satisfy himself re- garding the character and amount of loam, clay, sand, quicksand, gravel, hard pan, rock, water, and all other material to be encountered and work to be performed. (c) Clearing and Grubbing - The site of all excavations, embank- ments and fills shall be first cleared of building, fences, lumber, walls, stumps, brush, weeds and rubbish, trees and loose boulders, which shall be removed or disposed of in a manner satisfactory to the Engineer, and the area grubbed to a depth of not less than 18-inches. (d) Trenches and Tunneling - The Contractor shall make all neces- sary excavation to construct all work shown upon the plans.. Where open trenches or tunnels are not so indicated, the pipe may be laid in open trenches, or in sections of open trenches connected by tunnels, the length of which tunnels shall not exceed one-half (1/2) the depth of the subgrade below the surface of the ground; provided, however, that the tunnel length shall in no case be more than eight (8) feet for tile pipe and fourteen (14) feet for cast iron pipe, and open trenches between tunnels shall be not less than eight (8) feet in length. For steel or cement-mortared and lined steel pipe the tunnel length shall not exceed twenty (20) feet. Tunnels shall have a height which will provide sufficient clear space above the top of the pipe to allow proper workmanship. In no case shall this be less than two (2) feet. If the bottom of the excavation is found to consist of rock or any material that by reason of its hardness cannot be excavated to give uniform bearing surface, said rock or other material shall be removed for at least three (3) inches below the bottom of the pipe and be refilled to grade with sand or sand and gravel thoroughly tamped into place, at the Contractor's expense for all labor and material. 114. All water pipe and appurtenances shall be laid in trenches separate EZ - 1 from those used for sewers. Unless otherwise specified, such extensions shall be laid in trenches having a depth of not less than three (3) feet below the surface of the ground and located at a distance from the sewer trench of not less than three (3) feet. (e) Width and Depth of Trench - The width of the trench, in the clear, for water pipe measured at the top of the pipe, shall be not less than sixteen (16) inches, plus the outside diameter of the pipe, nor greater than twenty- four (24) inches plus the outside diameter of the pipe. If any trench, through neglect of the Contractor, be excavated below the bottom grade as required by the plans, it shall be refilled to grade with sand or sand and gravel thoroughly compacted in place, at the Contractor's expense for all labor and materials. If any trench be excavated to a width greater than above specified, the pipe shall be placed in a Class "C" concrete saddle extending from the lowest projected line of the outside diameter of the pipe to a level one- fourth of the outside diameter of the pipe above the springline of the pipe at the Contractor's expense for all labor and materials. (f) Shoring - Where necessary, all trenches and other excavations shall be properly sheeted and braced, to furnish working conditions accept- able to the Engineer. The bracing shall be so arranged as not to place any stress on portions of the completed work until the general construction thereof has proceeded far enough to provide ample strength. Any damage to structures occurring through settlements, water or earth pressures, slides, caves or other causes, due to failure or lack of sheeting or bracing or im- proper bracing, or through negligence or fault of the Contractor in any other manner shall be repaired by the Contractor at his own expense. (g) Unauthorized Excavation - Wherever the excavation is carried beyond or below the lines and grades given by the Engineer, the Contractor shall, at his own expense, refill all such excavated space with such material and in such manner as may be directed, in order to insure the stability of the various structures. Beneath all structures, space excavated without authority shall be refilled with Class "C" concrete or gravel by the Contractor at his own expense. (h) Additional Excavation - It is expected that satisfactory materials for foundations will be found at the elevation shown on the plans, but in case the materials encountered are not suitable or in case it is found desirable or necessary to go to additional depth or width as the Engineer may direct, additional excavation so ordered, and concrete or gravel ordered for filling such additional excavation, will be paid for as hereinbefore outlined for extra work. No payment will be allowed the Contractor for additional excavation and additional concrete and gravel for filling such additional excavation if such work and materials is necessary as a result of the Contractor's failure to properly remove water from his excavation as hereinafter specified in 114 Section E-2 (k). EZ - 2 (i) Clearance for Structures - The excavation for all structures shall be suffici-ent to leave at least six (6) inches in the clear between their outer surfaces and the embankments or timbering which may be used to protect them. (j) Blasting - The Engineer shall have the right to limit the use of explosives and/or to order discontinuance of the use of any methods in this connection which, in his opinion, endanger any part of existing structures or public or private property of any character. No blasting will be allowed except by special permission, in writing, from the Engineer. (k) Removal of Water - The Contractor shall at all times during construction provide and maintain ample means and devices with which to promptly.remove and properly dispose of all.water entering the .excavations or other parts of the work and shall keep said excavations dry until the pipelines or structures to be built therein are completed. No concrete shall be laid in water nor shall water be allowed to rise over concrete until it has set at least twenty-four (24) hours. In water bearing sand or quicksand, if ordered by the Engineer, a suitable equipment of well points or sheeting shall be supplied with pump and other appurtenances of ample capacity to keep a dry excavation as specified. The Contractor shall dispose of the water from the work in a suitable manner without damage to adjacent property. No water shall be drained into the work built or under construction unless the consent of the Engineer is first obtained. Water shall be disposed of in such manner as not to cause injury to public or private property, nor to be a menace to the public health. (1) Disposal of Material - Material excavated shall be disposed of in backfilling, making fills, grading around the work as may be directed to the lines and grades given by the Engineer, and surplus material removed from the Board property and/or right-of-way. No excavated material shall be dumped near enough to the work to cause pressure against newly placed or set masonry. No surplus material shall be dumped on private property unless written permission is furnished the Contractor, signed by the owner of the property. No extra payment for removal of excess material will be made as such, and any cost in connection therewith shall be included in the bid for excavation as set forth in the proposal. (m) Backfilling - No backfilling shall be placed against concrete walls until the walls have been inspected and approved by the Engineer. Any shoring shall be carefully and completely removed as the backfilling pro- gresses. BUS E2 - 3 The material used for backfill shall be free from debris or other foreign material, and shall be placed in uniform layers of thickness as specified hereinafter, each layer to be moistened and thoroughly compacted before the placing of the next layer. Backfill adjacent to any buildings shall be placed in layers not ex- ceeding eight inches in thickness, and otherwise as specified above. All lumber, rubbish and braces shall be carefully removed from ex- cavations, unless ordered left in place by the Engineer. Unless otherwise specified, all excavations shall then be backfilled up to the original surface of the ground or to such grades as shall be directed. The backfilling shall be done as completely as possible in such manner as to prevent aftersettle- ment. Around all structures, the trenches and excavations shall be thoroughly wet down with water while the backfilling is being placed. All backfilling of trenches shall be done in such a manner as not to disturb the pipe, conduit or other structure. In all cases, the backfilling around pipe shall be carried up to six (6) inches above the top of the pipe by hand with selected materials or sand free from large stones or lumps and thoroughly compacted while being placed with the aid of an approved tamp- ing device. The trench shall then be backfilled to the surface in layers not to exceed 18" in depth, properly wetted and tamped in a manner approved by the Engineer. A "V" notch shall then be excavated in the fill and the fill settled with water and backfilled to grade. Where sheeting is drawn, all cavities remaining in or adjoining the trench shall be solidly filled. Where sheeting is left in place, all cavities behind such sheeting shall be solidly filled. Excess material shall be rounded up in a neat mound over the trench or removed as directed by the Engineer. All backfill shall be compacted to a relative compaction of not less than ninety (90) percent.

Embankments and fills shall be built of the materials removed from B128 the excavation, so far as possible, arranging them in the most suitable manner. E2 - 4 Unless otherwise specified all embankments and fills shall be com- pacted to a relative density of not less than 90% as determined by the com- paction test method hereinafter specified. Fills and embankments shall be arranged in a manner and composed of materials approved by the Engineer free from vegetable matter or other unsatisfactory matter. High clay content or high shrinkage factor earth or soil shall not be used in fills or embankments. Prior to placing any fill or embankments, the area over which fill or embankment is to be placed shall be cleared of all debris, holes or pits, and holes or pits shall be backfilled and tamped thoroughly with earth from the site. The area shall then be plowed to a depth of not less than 12 inches, the surface of the ground restored to approximately its original contour by blading or other method and then compacted as hereinafter specified. The fill or embankment shall be constructed in layers approximately parallel to the finished grade. . The layers shall be evenly spread to a depth of not over g inches and shall be uniform as to material, density, and moisture content. Material placed in the embankment in piles or windrows shall be moved by blading or similar method, breaking up clods or lumps. Water shall be evenly applied and worked to secure a uniform moisture con- tent for maximum compaction throughout each layer. Then each layer shall be immediately compacted by tamping or sheep's foot rolling, pneumatic rollers or other mechanical tampers of a size and type required to obtain the required compaction and approved by the Engineer. The surface of all embankments shall be carefully graded to the lines shown on the drawings or given by the Engineer and shall be left above the finished ground specified, if directed by the Engineer, to allow for settle- ment. (p) Compaction Tests - Relative compaction of compacted fill will qe determined by the "Five Layer Method", as specified in California Test Method No. Zlb-E. (q) Regrading and P.eoaving Streets - The Contractor shall restore the streets or roadways to a condition satisfactory to the Engineer and to the County Highway Superintendent and/or the City or State Highway Depart- anent, as the jurisdiction may be.

The apparatus provided for weighing the aggregates and cement shall be suitably designed and constructed for this purpose. Each size of aggregate and the cement shall be weighed separately. The accuracy of all weighing devices shall be such that suc- cessive quantities can be measured to within 1% of the desired amount. Cement in unbroken standard packages (sack) need not be weighed, but bulk cement and fractional packages shall be weighed. The mixing water shall be measured by volume or by weight. -The water measuring device shall be susceptible of control accurate to within 1116 of the desired amount. All measuring devices shall be subject to approval. (k) Concrete Proportions and Consistency - The concrete shall be of such consistency and composition that it can be worked readily into the corners and angles of the forms and around the reinforcement without ex- cessive spading and without permitting the materials to segregate or free water to collect on the surface. The proportions shall be such as to secure the lowest water cement ratio which is consistent with good workability, a plastic, cohesive mixture, and within the specified range of slump. For concrete less than 4-inches in. 114 thickness the mix shall be modified as directed by the Engineer to facilitate placing. E3 - 3 The proportion of fine and coarse aggregate shall be such that the CD ratio of the coarse to the fine shall be not less than 1. 0 nor more than 2. 0 nor shall the amount of coarse material be such as to produce harshness in placing or honeycombing in the structure. To avoid unnecessary or haphazard changes in consistency the aggregate shall be obtained from a source which will insure uniform quality, moisture content, and grading during any single day's operation, and they shall be delivered to the work and handled in such a manner that variations in moisture content will not interfere with the steady production of concrete of the specified degree of uniformity and slump. It is the Contractor's responsibility to adjust the concrete batch weights so as to secure the maximum yield yet at all times he shall main- tain the proportions of the concrete mix within the specified limits. If, in the opinion of the Engineer, it is required, the mixture shall be modified as directed by the Engineer within the limits set forth in these specifications. (1) Field Test of Concrete - Field tests of concrete will be made by the Engineer in accordance with the "Standard Method of Test for Compres- sive Strength of Molded Concrete Cylinders" (Serial Designation C39 latest revision of the American Society for Testing Materials). During the progress of the work a reasonable number of compression tests will be made by the Engineer. (m) Mixing (1) General - Mixing equipment shall be subject to approval. Mixers may be of the stationary plant, paver, or truck mixer type. Each mixer shall be equipped with a device for accurately measuring and indica- ting the quantity of water entering the concrete, and the operating mechan- ism shall be such that leakage will not occur when the valves are closed. Adequate equipment and facilities shall be provided for accurate measure- ment and control of all materials, and for readily changing the proportions of the material. The batch plant shall be capable of controlling the delivery of all material to within one (1) percent by weight of the specified materials. If bulk cement is used, it shall be weighed on a separate visible scale which will accurately register the scale load at any stage of the weighing operation from zero to full capacity.

(2) Stationary or Paver-Type Mixers - The minimum time for mixing Each batch after all materials, including water, are in the mixer shall be as follows: Class "A" Concrete 2 minutes 114 Class "B" Concrete 2 minutes Class "C" Concrete 1-1/2 minutes E3 - 4 Each miner shall be equipped with a device for automatically measuring and indicating the time required for mixing, which device shall be interlocked to prevent the discharge of concrete from the mixer before the expiration of the mixing period. The mixers shall revolve a minimum of twenty (20) revolutions after all materials have been placed in them and at a uniform speed. Neither speed nor volume capacity of the mixer shall exceed manufacturer's recom- mendations. Excessive overmixing, requiring additions of water to pre- serve the required consistency, will not be permitted. (3) _ Transit-Mixed Concrete General - Transit-mixed concrete may bE; used in lieu of concrete mixed at the job, for all concrete to be placed in structures. All applicable mixing requirements specified herein for concrete mixed at the site shall govern transit-mixed concrete and the Engineer shall have free access to the mixing plant at all times. Top-Loading Truck Mixers - For concrete mixed in top- loading truck mixers, each batch shall be turned not less than forty (40) and not more than one hundred fifty (150) revolutions of the mixer drum at mix- ing speed when the fine and coarse aggregate are charged into the mixer simultaneously (cement and water may be charged separately). When the fine and coarse aggregate are charged into the mixer separately, each batch shall be turned not less than sixty (60) and not more than one hundred fifty (150) revolutions of the drum at mixing speed. End-Loading Truck Mixers - For concrete mixed in end- loading truck mixers, each batch shall be turned not less than sixty (60) and not more than one hundred fifty (150) revolutions of the mixer drum at mixing speed when the mixer is loaded in excess of fifty percent (50%) of the gross drum volume as provided hereinafter. When the mixer is loaded not to exceed fifty percent (50%) of the gross drum volume, the provisions specified for top-loading truck mixers will apply. Capacity - Truck mixers shall be loaded in accordance with manufacturer's capacity ratings, but in no case shall the volume of mixed concrete exceed fifty percent (50%) of the gross volume of the drum for top- loading mixers and fifty-eight percent (58%) of the gross volume of the drum for end-loading truck mixers. Mixing Speed - shall be in accordance with manufacturer's recommendations, but in no case shall the speed be less than 4 R. P. M. or greater than a speed resulting in a peripheral velocity of the drum of two hundred twenty-five (225) feet per minute. The power unit shall be equipped with a governor to insure constant speed. Control - Each truck mixer shall be equipped with a device for counting the number of revolutions of the drum, which device shall be interlocked so as to prevent the discharge of concrete from the drum before 114 the required number of turns. After the drum is once started, it shall be E3 - 5 revolved continuously until it has.completely discharged its batch. Water shall not be admitted to the mix until the drum has started revolving. The right is reserved to increase the required minimum number of revolutions or to decrease the designated maximum number of revolutions allowed if necessary to obta.0 satisfactory mixing, and the Contractor will not be entitled to additiaa _` co-mpensation because of such increase or decrease. (4) Hasid-Mixed Concrete; - tVhen necessary, to mix by hand, a water-tight platform sh5 1 be used and ingredients shall be turned together at least six (6) times, and until they are homogeneous in appearance and color. (n) Cement Mortar or Grout - Cement mortar for the repair of im- perfect concrete work, the filling of holes left by form bolts and ties, and the filling of voids around piping through concrete shall consist of cement and sand mixed in the same proportions as used for the concrete being repaired, with only sufficient water to give the required consistency. Bolt holes shall be filled with dry pack mortar, well tamped into holes. Grout for spreading over the surfaces of construction joints shall consist of water and cement mixed in the ratio of not to exceed seven (7) gallons per sack with sufficient sand added to produce the desired worka- bility of the mass. Partipular care shall be exercised in placing cement mortar or grout since it will be expected to furnish structural strength or an impermeable water seal or both. Cement mortar or grout that has not been placed within thirty (30) minutes after mixing shall be wasted. Grout used in setting machinery and equipment shall consist of a moist mixture of one (1) sack of cement to one (1) cubic foot of sand to one hundred (100) pounds of Master Builders "Embeco" carefully worked and rodded or tamped in under the machinery bases in such a manner as to preclude voids or pockets under the metal base. The edges shall be neatly finished. Concrete surfaces shall be roughened, cleaned, and soaked be- fore grout is placed. All cement mortar or grouting mixtures, application methods and placing tools shall be subio:ct to the approval of the Engineer.

Forms, centering, cores and molds shall be so constructed that the finish concrete will conform to the shapes, lines, grades and dimensions indicated on the drawings. No form shall be used which is not clean and of proper shape and strength and in every way suit- able. Deformed, broken or defective forms shall be removed from the . work. Before placing concrete, the forms shall be coated with vaseline, form grease, or other suitable substance, to prevent adherence of concrete. All forms and form lumber once used shall be thoroughly cleaned and con- tact surfaces recoated before again being used. 114 E3 - 6 Plywood forms shall be used for all surfaces exposed to view in the finished structure whether inside or outside of any structure. Channels and tank walls backfilled with dirt may be formed with lined forms. The contact surface of all unlined forms, unless otherwise specified, shall be constructed of 5/8-inch or 3/4-inch five ply Douglas fir plywood made with a waterproof glue and especially manufactured for concrete form- work. Full sized sheets of plywood must be used except where smaller pieces will cover an entire area. All horizontal and vertical joints shall be backed solidly to prevent leakage and the edges of abutting sheets shall be nailed to the same stud or blocking with 6d box nails not farther apart than eight (8) inches. The contact surface of lined forms shall be nor.-warping fibre board not less than three-sixteenths (3/16) inch in thickness, or one-quarter (1/4) inch plywood, securely nailed to the form sheathing. All lining material shall be used in as wide pieces as possible. The boarding for lined forms may be horizontal or vertical depending upon convenience. Form sheathing shall be securely nailed to studs and so spaced as to prevent any bulging of the lining. Steel forms or steel-reinforced plywood forms made by a reputable manufacturer may be substituted for any of the above form-work. All studding shall be of not less than 2" x 4" lumber and studding and wales shall be of sizes and spacing approved by the Engineer, but in no case more than 2411 O. C. Wales shall be formed of double 2" x 4" lumber as a minimum. All wall forms shall be tied together by means of approved wall ties on not greater than two (2) foot centers vertically and horizontally. The approved form tie shall be of such design that, wh .n the forms are removed, no metal shall be within three-fourths (3/4) inch of any sur- face. They shall not be fitted with any lugs, cones, washers, or any other devices to act as a spreader within the form which will leave a hole larger than seven-eighths (7/8) inch in diameter in the exposed surface of the con- crete. Wire ties will not be permitted. Holes in the forms for ties shall not allow leakage during pouring. The tops of wall and corbel forms shall be stiffened by means of 2" x 411 or 2" x 6" plates. No forms on any part of the work shall be struck without the consent of the Engineer. . All formwork shall be securely braced, supported or otherwise held in place in such manner as to prevent any bulging surfaces on the faces of finished concrete work and as required to prevent any movement or "slipping" of formwork. No concrete shall be poured until all forms have been thoroughly checked for alignment, level and strength. All cracks or 114 openings at joints in formwork which are one-eighth (1/8) inch or more E3 - 7 in width shall be closed by tightening the forms or by filling with an approved crack filler or putty. (p) Conveying Concrete - Concrete shall be conveyed from the mixer to the place of final deposit by methods which will prevent the separation or loss of the materials. Equipment for chuting, pumping and pneumatically conveying concrete shall be of such size and design as to insure a practically continuous flow of concrete at the delivery end without separation of the materials. Chutes and devices for conveying and depositing concrete shall be so designed and used that the concrete shall be directed vertically downward when dis- charged from the chute or conveying device. Chutes for conveying concrete shall be kept thoroughly clean by washing and scraping upon the completion of any days pour. (q) Placing Concrete - No concrete shall be placed without the prior approval and direct supervision of the Engineer. The Contractor shall notify the Engineer, by written memorandum, of his readiness to place con- crete in any portion of the work. This notification shall be such time in ad- vance of the operation as the Engineer deems necessary for him to make final inspection of the preparations at the location of the proposed concrete placing. . Concrete shall be placed in approximately horizontal layers not to exceed twenty-four (24) inches in depth and the concreting shall be carried on in a.continuous operation, within the limits of practicability, until the placing in the course, section, panel, or monolith is completed. Concrete shall be deposited at or near its final position to avoid segregation caused by rehandling or flowing. No concrete shall be dropped freely into place from a greater height than five (5) feet. Tremies shall be used for placing concrete where the drop is in excess of such height. . Concrete in structures shall be placed with the aid of approved mechanical vibrating equipment. Vibration shall be transmitted directly to the concrete; in no case shall it be transmitted through the forms. The vibration shall be sufficiently intense to cause the concrete to flow or settle readily into place and to visibly affect the concrete over a radius of at least eighteen ( 18) inches. Vibration shall be supplemented by manual fork- ing or spading adjacent to the forms on exposed faces in order to secure smooth, dense surfaces. The concrete shall be thoroughly consolidated around reinforcement, pipes, or other shapes built into the work. Sufficient vibrators shall be on hand at all times to vibrate the con- crete as placed. In addition to the vibrators in actual use while concrete is being placed, the Contractor shall have on hand two (2) spare vibrators that are in serviceable condition. No concrete shall be placed until it has been ascertained that all vibrating equipment will be in serviceable condition for the duration of the placing operation. 114 . Special care shall be taken to place the concrete solidly against the E3 - 8 forms so as to leave no voids. Every precaution shall be taken to make all concrete solid, compact, and smooth, and if for any reason the surfaces have voids or are in any way defective, such concrete shall be repaired as directed by the Engineer. No defective work shall be patched or repaired without the prior inspection and approval of the Engineer. The repair shall be with cement mortar applied by such methods as will produce a satisfac- tory bond with concrete in place and finished in a neat and workmanlike manner to match as closely as possible, the color and texture of the adjacent work. Defective work shall be removed if required by the Engineer. Concrete shall not be placed until all reinforcement is securely and properly fastened in its correct position, and loose form ties at construction joints have been retightened, nor until all dowels, bucks, sleeves, hangers, pipes, conduits, bolts, wires, and any other fixtures required to be em- bedded therein have been placed and adequately anchored, nor until the forms have been cleaned and oiled as specified. No concrete shall be laid during rainstorms. Concrete placed immediately prior to rainstorms shall be protected to prevent the water from coming in contact with it. Sufficient protective covering shall be kept on hand at all times for this purpose. Concrete placing shall continue without avoidable interruption, unless otherwise specified, until the predetermined limit of the placement has been attained. The placement of concrete in wall forms shall not proceed at a faster rate of rise than six (6) feet per hour when the temperature is 70 degrees F. and at a lesser rate of rise for lower temperatures, as approved by the Engineer. The placement of concrete for slabs or beams cast monolithically with walls or columns shall not commence until the concrete in the walls or columns has been allowed to set and shrink. The time allowed for shrinkage shall be not less than six (6) hours. Placement of concrete on slopes shall commence at the bottom of the slope , and be brought up in uniform horizontal lifts. Placing of concrete in which initial set has occurred or placing of retempered concrete will not be permitted. (r) Watertightness of Concrete Work - Watertight concrete is re- quired in all Class "A" concrete structures. Any cracks or imperfections developing at any point in the work shall b-- repaired as specified above. (s) Joints and Bonding - Where shown on the plans the concrete work shall be constructed as a monolith. The location of contraction, con- struction, and other joints are shown on the plans or specified herein. In order to preserve, the strength and watertightness of the structures, no other joints shall be made except as the Engineer may direct or approve. At construction joints, the concrete in place shall be thoroughly cleaned of laitance, grease, oil, mud, dirt, mortar droppings or other objectionable matter by means of a bushing hammer or sand blasting after which the sur- faces shall be washed just prior to the succeeding pour. Upon resuming 114 concrete placing operations, a bed of grout not less than one (1) inch in E3 - 9 thickness shall be thoroughly spread over the entire surface. Keyways on vertical joints shall be set to extend into subsequent sections of the con- struction as shown on the plans. Floor slabs in the area of their juncture with walls shall be washed free of sawdust, chips and other debris after wall forms are built and im- mediately before the concrete placement. Should formwork confine sawdust, chips, or other loose matter in such manner that it is impossible to remove them by flushing with water, a vacuum cleaner shall be used for their re- moval after which the cleaned surface shall be flushed with water. A clean out hole shall be cut at the base of each wall or column for inspection and cleaning. The Contractor shall schedule his pouring in such manner as to com- plete any single day's pour to a construction, contraction or expansion joint. The concrete pouring diagram as shown on the plans shall be followed. (t) Inserts - Pipes, anchor bolts, steps, casings, and other inserts as shown on the plans, shall be encased in the concrete, unless otherwise noted. Dovetail anchors or ties shall be used in conjunction with the slots or inserts for the various materials as specified under their respective sections, and as may be necessary for the required work. (u) Finishing - Cavities produced by form ties and concrete surfaces requiring repair shall be thoroughly cleaned, saturated with water, and care- fully filled and pointed with cement mortar as specified hereinbefore under "CONCRETE". Such finishing shall occur immediately following the stripping of forms so as to incur the least possible delay in commencing the curing of the concrete as specified under "CARE OF NEW WORK". No other concrete finish is required for formed surfaces except as noted below. All exposed walls shall have all fins and projections removed. Joints shall be left smooth by grinding if necessary, however, it will not be neces- sary to remove form marks if the joints are smooth. All slabs and floors including concrete placed on slopes shall be first wood float finished and then steel troweled to a smooth finish. Finished surfaces for concrete slabs including those placed on slopes shall be not less than the finish grade shown on the plans, and not more than 1-inch above finish grade when measured with a 10-foot straight edge. Floors with drains shall be properly sloped toward drains. The tops of walls shall be steel troweled. Top edges of coping, walks, and walls, if not otherwise required, shall be finished with a one (1) inch radius edger, the flanges of which shall be ground to a knife edge to produce as little burr as possible. Remaining burrs on the lower side of the finished radius, after the form has been removed, shall be rubbed off and the surface left smooth. C 117 Jointing where indicated or directed shall .be carefully done with a jointing tool. E3 - 10 (v) Care of New Work - All surfaces of concrete for water-bearing structures: shall be kept constantly and visibly moist day and night for a period of not less than seven (7) days and nights beginning irximediately upon removal of forms. Each two (2) days the forms remain in place, up to a maximum of six (6) days, shall count as one (1) day of water' curing. No further curing credit will be allowed after contact has once been broken between concrete surface and forms. Ties shall not be loosened. All exposed surfaces of concrete for non-water bearing structures shall be cured by covering slabs with waterproof curing paper and sealing all edges and leaving forms in place for seven (7) days followed by applica- tion of water by means of sprinkler nozzles or sprays, keeping the concrete constantly moist for a period of one (1) day and night. Supports and forms for struts, beam, and floor or roof slab soffits shall remain in place for at least seven (7) days after concrete has been placed for any concrete which carries its own weight only. For concrete members carrying additional or live loads, the Engineer shall determine when forms may be removed. In lieu of continual curing by moisture of water bearing concrete, the Contractor may substitute a combined process covering of the concrete, using spray nozzles for one full day and immediately thereafter spraying concrete with an approved waterproof curing compound. The use of any such substitution method must be first requested by the Contractor in writing and approved by the Engineer. (w) Measurement and Payment (1) Measurement of concrete will be on the basis of a complete job of furnishing and placing concrete as described in the preceding para- graphs of this section, and shall include all concrete and incidentals there- to including water stops, expansion joints and contraction joints, for a com- plete job in accordance with the plans and specifications. (2) No separate payment for concrete as such will be made, and the Contractor shall include all costs thereof in the applicable contract bid item. C117 E3 - 11 E-4.

All fabricated steel pipe and fab- ricated steel pipe fittings shall be constructed and furnished by the same manufacturer. The Contractor shall furnish pipe and fittings in accordance with the terms of his proposal and the requirements of these specifications and drawings, and shall guarantee for a period of one year all such material and workmanship as is hereunder furnished or supplied. The pipe approved by the Engineer and furnished and installed by the Contractor shall conform to the plans and specifications. An alternate pipe detail design, provided it is equal or better in every respect than those shown on the drawings or specified herein may be submitted by the Contrac- tor in his proposal, but the Board reserves the right to reject any bid con- taining such an alternate proposal if the Board finds any questions as to the merits of the alternate. D127 Regardless of the main type of pipe approved by the Engineer and the Board, the Contractor shall furnish all labor, pipe materials, fittings, and E5 - 1 all other materials, all necessary equipment, and all incidental labor, mater- ials and equipment required to complete a tested and working pipeline as pro- jected on the drawings and specified herein. All replacements or repairs of lines carrying air or gas shall be tested for tightness after erection as far as practicable. Replacement or repair of pipelines carrying water, sewage or sludge shall be tested by filling with water under a minimum hydrostatic pressure of fifty (50) pounds per square inch in excess of the normal operating pressure or as directed by the Engineer. All visible leaks shall be repaired. All tools, materials, except water, and appliances including bulkheads, required for making the tests shall be supplied by the Contractor at his own expense. Where pipelines are laid in excavation under pavement, or bedded in concrete, testing as specified hereinafter shall be done prior to refilling or placing ofthe pavement or concrete. All pipelines shall be left thoroughly clean. After the pipeline has been backfilled and then tested and before putting into service, all new drinking water lines shall be chlorinated as specified hereinafter and as directed by the Engineer.

Quality of Steel - Steel plates or sheets used in the manufacture of the pipe shall conform to the physical properties of American Society for Testing Materials Specification A-283 Grade "C" (for plates) or Specification A-245 Grade "B" (for sheets), both of the latest revision. The plates or sheets shall conform to the gauge or thickness specified, said gauges being in accordance with Manufacturers' Standard Gauge Table and having a definite thickness, equivalent for each gauge number (see American Iron and Steel Institute "Steel Products Manual' of September, 1949, Sections 6 and 11). b. Fabrication - Pipe shall be manufactured in accordance with AWWA Specification C-201 and C-202, except as herein provided. The diameter specified shall refer to the finished net inside diameter of the com- pleted pipeline and the Contractor shall take into consideration lining thick- ness in placing orders for pipe. The pipe shall be manufactured in courses not less than 10 feet long having not more than two longitudinal and three circumferential seams per section, except where shorter lengths or more than one of either type of welded seam are required by special conditions. .All longitudinal seams shall be butt welded from the exterior D126 E5 - 2 against copper faced mandrels with either single or twin arc electrodes, de- pending on the wall thickness. All circumferential seams shall be butt welded from the exterior and when required from the interior as well, using single arc electrodes for each such weld. All seams shall be welded by an approved shielded arc process which protects the weld metal from, the atmos- phere while cooling and which assures full fusion with the parent metal and complete penetration. All pipes and pipe joints shall be of uniform diameter and work- manship. Any pipe either before or after placing of cement mortar lining and cement mortar coating will be rejected if not in complete accordance with these specifications. The manufacturer of the pipe to be furnished shall have had three (3) years of experience manufacturing pipe of a similar size and type. The Engineer shall be the sole judge that this experience qualifies the manu- facturer to furnish the pipe. C. Ends of Pipe Sections - Standard ends of pipe sections shall be bell and spigot, rubber gasket type, as shown on the drawings or approved by the Engineer, circular in shape and so designed and fabricated that when the pipe is laid, the joint will be self-centering. The joint shall be so designed that the gasket will be completely enclosed by steel on all four sides. Both ends shall be formed in such a manner to insure perfect roundness of the ends and a groove of uniform dimensions. The difference in circumferential measurement between the outside circumference of the spigot and the inside circumference of the bell shall be 0. 060 inch minimum and 0. 18 inch maximum. The gasket shall not be required to bear the weight of the pipe. The outlined interior surface of the bell and the uncoated exterior surface of the spigot shall be protected by a corrosion-.resistant paint. The joint shall be so proportioned and the gasket shall be of such a size that the gasket will be confined and compressed sufficiently to make a watertight joint under the combined condition of maximum bell circumfer- ence and maximum unsymmetrical closure. The manufacturer shall keep production records of measurements made on the bell and spigot of each length of pipe. Other ends where called for on the drawings shall be of the following types or equal. 1. Ends for Mechanically Coupled Field Joints - Ends for Dresser type couplings shall be plain with the weld bead ground flush outside for the required distance back from each end. For Victaulic type couplings, ends shall be banded, or provided with shouldered ends. For bolted joints, ends of sections shall be swaged if required. 2. Ends for Caulked Field Joints - One end of each section shall be swaged out to form a caulking bell. It shall be enlarged sufficiently to secure a caulking space approximately 5/8-inch wide (at its greatest width) by 4-1/2 inch long. There shall be a secondary enlargement beyond the caulking space to provide a centering socket for the spigot or 114 plain end which shall permit the latter to enter approximately 1 inch beyond E5 - 3 the caulking space. The caulking bell shall be formed hot, in one operation, using a die or dies which assure that the bells as made will be uniform and round. After swaging, the end of the bell shall be reinforced by shrinking on and tack welding a steel ring of the proper diameter. The steel bar from which the ring is made shall have appropriate cross-sectional dimensions ranging between 3/16" x 1" and 1/2" x 3", depending on the pipe diameter. 3. Plain Ends Fitted with Flanges - Ends to be fitted with flanges shall have the weld bead ground flush for the distance the flange is to slip over the end. Flanges shall be welded to the pipe ends with full fillet welds both inside and outside. Flanges shall conform to the require- ments of Section E-6 (e) g of these specifications. All flange bolts and nuts, except where otherwise specified, shall be made of the best quality refined iron or mild steel, and shall have sound, well fitting threads. Bolts shall be provided with standard hexagonal cold-pressed nuts and standard square heads, unless hexagonal heads are required for clearance. Flange bolts for each size of flange shall be of the diameter required, and of such a length that, after installation, they will not project more than three-eighths (3/8) inch beyond the outer face of the nut. Gaskets of "Cranite" or equal, one-sixteenth (1/16) inch thick shall be used in all flanged joints, full face type. d. Rubber Gasket - The rubber gasket used for sealing field joints shall be made of special composition rubber, shall be circular, and of such size as to provide a watertight joint. T he rubber compound shall consist of first grade natural rubber, synthetic rubber, or a suitable com- bination thereof. The gasket shall be the sole element depended upon to make the joint watertight. The gaskets shall be furnished with the pipe. Gaskets shall conform to the following physical requirements when tested in accordance with Federal Test Method Standard No. 601. 1. Tensile Strength - The tensile strength of the com- pound shall be not less than 2, 700 p. s. i for natural rubber or 2, 300 p. s. i. for synthetic rubber. (Method 4111). 2. Elongation of Rupture - Two-inch gauge marks shall stretch to not less than ten inches (LUTF at rupture. (Method 4121). 3. Specific Gravity - The specific gravity shall be be- tween 1. 15 and 1. 25. (Method 14011). I 4. Compression Set Test - The compression set shall not exceed twenty percent 20 0 (Method 311). 5. Tensile Strength After Agin - The tensile strength of the compound shall be not less than eighty percent (80%) of the tensile D122 strength before aging after being subjected to an accelerated aging test in an E5 - 4 air oven for 96 hours at 1580 F. (Method 722); or in an oxygen bomb test for 48 hours, 1580 F. 300 p. s. i. (Method 7111). e. Testing - Each section of pipe shall be hydrostatically tested under an internal pressure to 85%n of the specified yield point fiber stress of the plate or sheet furnished. While under this pressure the pipe shall be sharply struck at six inch intervals along the weld with a 1-1/2 pound hammer, with blows equivalent to dropping the hammer a distance of one foot for No. 14 gauge pipe, increased by an increment of six inches for each increase in thickness by one gauge number. The blows shall be struck in such a manner as to thoroughly jar the weld. Immediately after the hammer test has been completed the pressure shall be maintained a sufficient length of time to allow for the inspection of the section for tight- ness. All leaks shall be repaired by chipping to sound metal, hand welding, and the section then re-tested. All tests shall be made against a fabricated field joint mandrel. f. Application of Cement Mortar Lining and Coating 1. Materials - Pipe shall comply with detail specifi- cations herein for Welded Steel Pipe, (Paragraph E-5 (b) (1). All objection- able matter, such as loose mill scale, rust, dirt, oil or grease, shall be removed from the pipe prior to the application of the cement mortar lining and coating. The steel pipe shall be designed to operate under the specified maximum working pressure, using an allowable stress of 15, 000 p. s. i. No strength value shall be given concrete mortar or any reinforcing material for withstanding internal pressure. Cement used in cement mortar shall comply with A. S. T. M. Specifications C-150, Type II. Aggregate used in cement mortar shall be composed of clear, sharp, durable grains graded as required by the application process. Water used in cement mortar shall be clean and free from objectionable quantities of organic matter, alkali, salts or other dele- terious substances. The cement mortar used for the inside and outside coat- ings shall be composed of mixtures of cement, aggregate and water as above, well mixed and of the proper consistency to procure dense, homogeneous lining and coating materials. All cement mortar shall develop an ultimate compressive strength of not less than 2, 600 p. s. i. at 7 days and 4, 500 p. s. i. at 28 days as determined by Paragraphs 19 and 20 of A. S. T. M. Specification C-39, latest revision. The mortar used for lining and coating shall consist of 1 part of Portland Cement to not more than 3 parts of aggregate by weight with a minimum amount of water to give the best overall results with the particular material and method used for the work. Steel reinforcing wire used in the outside cement mortar coating shall be a bright basic wire of low carbon, open hearth steel, not annealed after the last draw, and with a minimum ultimate tensile strength of 80, 000 p. s. i. , and conforming to A. S. T. M. Specification A-82 - "Cold Drawn Steel Wire for Concrete Reinforcement. " 2. Interior Lining - The cement inortar shall be D120 applied to the inside of each section of pipe by means of troughs or retract- ing feed lines while the pipe is rotated with its axis in a horizontal position. E5 - 5 This initial application shall produce a uniform longitudinal distribution throughout the length of pipe. Then the pipe shall be rotated at a speed which will uniformly distribute the mortar around the inside circumference of the pipe and produce a dense, smooth and uniformly compacted lining. During the spinning operation, surplus water, which has been forced to the surface of the lining, shall be removed by a blower or other suitable means. Immediately after the spinning operation, each section of pipe shall be tilted to drain off any excess water still remaining, and each end shall be capped with a waterproof cover, properly attached, to prevent the escape of moisture from the interior of the pipe. The pipe shall be carefully moved to a storage area and cured under sprinklers without being disturbed for not less than 4 days if an exterior cement mortar coating is to be applied, for not less than 7 days if the exterior coating is omitted. 3. Exterior Coating - The cement mortar shall be applied to the outside of each section of pipe by means of a nozzle, or nozzles, through which the mortar is forcibly expelled against the outside surface of the pipe in such a manner as to form an even, dense and tightly adhering coating. During the coating operation, the pipe shall be rotated and moved in a longitudinal direction beneath the coating nozzles. The rotation and longitudinal travel of the pipe shall be uniform and at the proper rate to provide a coating of the specified thickness. The standard reinforc- ing for the cement mortar coating shall be a spirally wound steel reinforcing wire of the specified gauge, embedded in the coating. The gauge, pitch and radial position of the wire shall be as shown on the plans. Immediately after the coating has been completed, the outside of each end of each section shall be cleaned to bare metal and shall have the mortar troweled and shaped to suit the type of joint being used. All bare metal exposed at the ends of each section of pipe shall be cleaned and suitably protected. The pipe shall then be cured under sprinklers for not less than 7 days before being disturbed. g. Inspection - The Engineer or his authorized representa- tive shall at all times have the right to inspect the work and materials. The manufacturer shall furnish the Engineer reasonable facility for obtaining such information as he may desire regarding the progress and manner of the work and the character and quality of materials used. h. Loading and Transporting - After the pipe has been pro- perly cured, it shall be loaded on trucks or railroad cars and, when neces- sary, supported in such a manner, using adequate dunnage, steel saddles and padding, to insure the safekeeping of the pipe while in transit. During the loading and unloading operations, the pipe shall be handled in a workmanlike manner, and every precaution shall be taken to prevent damage to the coat- ing. Under no circumstances are sections to be dropped or bumped. i. Alternate Design - The design shown on the drawings and specified above is indicative of the type of welded steel pipe and joints de- sired by the Board. The Contractor may submit an alternate design of welded steel pipe and joints, mortar lined and reinforced cement mortar i B128 covered, as a basis for an alternate bid, but in any case he shall submit E5 - 6 his proposal on the basis of the design shown on the plans. Any alternate design not conforming to these plans and specifications as to minimum steel thickness, durability of exterior coating, and structural stability, will be rejected and the alternate proposal therefore rejected. The Board re- serves the right to reject any alternate bid if the Board finds any question as to the merits of the alternate. (2) Cast-Iron Pipe a.
