Adjustment, if any, in the amounts to be paid to the Contractor, by reason of any such change, addition or deduction, shall be determined by one or more of the following methods: By an acceptable lump sum proposal from the Contractor.

By ordering the Contractor to proceed with the work and to keep and present in such form as the District may direct, a correct amount of the cost of the change, together with all vouchers therefor. The cost may include allowance for overhead and profit not to exceed fifteen percent (15%) of the net cost. No extra work shall be performed or change made unless in the pur- suance of a written order from the District stating that the extra work or change is authorized, and setting forth the basis upon which payment therefor is to be made, and no claim for an addition to the contract sum shall be valid unless so ordered, provided however, that nothing in this article shall excuse the Contractor from proceeding with the prosecution of the work so changed. The Contractor shall, when required by the District, furnish an itemized breakdown of the quantities and prices used in computing the value of any change that might be ordered. (c) Removal of Obstructions: The Contractor shall remove and dispose of all structures, debris or other obstructions of any character to the construction of the work. Where such obstructions consist of improvements not required by law to be removed by the owner thereof, all such improvements shall be re- moved, maintained and permanently replaced by the Contractor at his expense. (d) Public Utilities; In case it should be necessary to move the property of any owner of a public utility or franchise, the cost of which, because of the terms of any franchise or for any other reason, must be borne by the owner thereof, such owner shall upon proper application by the Contractor be notified by the District's Representative to move such property within a specified reasonable time, and the Contractor shall not interfere with said property until after the expiration of the time specified. In case it should be necessary to move or temporarily maintain the property of any public utility or any other property, the cost of which is not required to be borne by the owner thereof, the Contractor' shall bear all expenses inci- dental to the removal or temporary maintenance of such property in a manner satisfactory to the owner thereof; it being understood that in such cases the owner has the option of doing such work with his own forces, or permitting the work to be done by the Contractor. The right is reserved to Governmental Agencies and to owners of public Boyle 103065 Standard Provisions - 2 utilities and franchises to enter at any time upon any street, alley, right of way or easement for the purpose of making changes in their property made nec- essary by the work, for the purpose of maintaining and making repairs to their property. (e) Final Clean-up; Upon completion and before making application for accep- tance of the work, the Contractor shall clean all rights of way, streets, borrow pits, and all other grounds occupied by him in connection with the work of all rubbish, excess materials, temporary structures and equipment, and all parts of the work shall be left in a neat and presentable condition. SECTION III - CONTROL OF THE WORK (a) Authority of the District's Representative; The District's Representative shall decide any and all questions which may arise as to the quality or accept- ability of materials furnished and work performed, and as to the manner of per- formance and rate of progress of the work, all questions as to the interpretation of the Plans and Specifications and all questions as to the acceptable fulfill- ment of the Contract on the part of the Contractor. The District's Representative may be represented on the work by duly authorized assistants. (b) Plans: The approved Plans shall be supplemented by such working drawings as are necessary to control the work adequately. All such drawings shall be consistent with the contract documents, true developments thereof, and reason- ably inferable therefrom. All such drawings delivered to the Contractor shall be deemed written instructions to the Contractor. The District will furnish to the Contractor, free of charge, all copies of drawings and Specifications reasonably necessary for the execution of the work. The Contractor shall keep one set of drawings and Specifications in good order available to the District's Representative and to his representatives at the site of the work. The Plans for the work show conditions as they are supposed or believed by the Engineer to exist; but it is not intended or to be inferred that the con- ditions as shown thereon constitute a representation by the District or its officers that such conditions are actually existent. The District, any of its officers, and the Engineer shall not be liable for any loss sustained by the Contractor as a result of any variance of the conditions as shown on the Plans and the actual conditions revealed during the progress of the work, or otherwise. (c) Conformity with Plans and Allowable Deviations; Finished surfaces in all cases shall conform with the lines, elevations, grades, cross sections, and dimensions shown on the Plans, or if no specific elevations are shown on the Plans, the elevations and grades furnished by the District's Representative shall govern. (d) Coordination of Plans and Specifications; The Plans, Specifications, and all supplementary documents are essential parts of the Contract and a require- ment occurring in one is as binding as though occurring in all. They are intended to be cooperative and to describe and provide for a complete work. In the event of an apparent difference between Plans and Specifications, refer- ence shall be made to the District's Representative, whose decision thereon shall be final. Boyle 103065 Standard Provisions - 3 (e) Interpretation of Plans and Specifications; Should it appear that the work to be done or any of the matters relative thereto are not sufficiently detailed or explained in the Specifications or on the Plans, the Contractor shall apply to the District's Representative for such further explanations as may be necessary and shall conform to them as part of the Contract, so far as may be consistent with the original Specifications; and in the event of any doubt or question arising respecting the true meaning of the Specifi- cations, reference shall be made to the District's Representative, whose decision thereon shall be final. In the event of any discrepancy between any drawing and the figures written thereon, the figures shall be taken as correct. (f) Supervision by the Contractor: The Contractor shall give efficient super- vision to the work, using his best skill and attention. Unless personally pres- ent on the premises where the work is done, the Contractor shall designate and keep an agent or representative on the work at all times during its progress, and any written or verbal directions or requests of the District's Represent- ative delivered to such representative shall have the same force and effect as if delivered to the Contractor personally. (g) Inspection: The District's Representative shall at all times have access to the work during construction and shall be furnished with every reasonable facility for ascertaining full knowledge respecting the progress, workmanship and character of materials used and employed in the work. Whenever the Contractor varies the period during which work is carried on each day, he shall give due notice to the District's Representative so that proper inspection may be provided. Any work done in the absence of the Dis- trict's Representative will be subject to rejection. No materials shall be installed until approved by the District's Representative or his representative. All installations which are to be backfilled shall be inspected and approved by the District's Representative prior to backfilling and the Contractor shall give due notice in advance of backfilling to the Dis- trict's Representative so that proper inspection may be provided. The inspection of the work shall not relieve the Contractor of any of his obligations to fulfill the Contract as prescribed. Defective work shall be made good, and unsuitable materials may be rejected notwithstanding the fact that such defective work and unsuitable materials have been previously over- looked by the District's Representative and accepted or estimated for payment. Any defective material or workmanship, or any unfaithful or imperfect work which may be discovered before the final acceptance of the work shall be corrected immediately on the requirement of the Engineer, or if such should be dis- covered within one year after the final acceptance, it shall be corrected immediately on demand of the District. All such corrections of defective materials or workmanship, or any unfaithful or imperfect work shall be made by the Contractor without extra charge, notwithstanding that it may have been overlooked in previous inspections and estimates. (h) Removal of Defective and Unauthorized Work: All work which has been re- jected shall be remedied, or removed and replaced by the Contractor in an acceptable manner and no compensation will be allowed him for such removal or replacement. Any work done beyond the lines and grades shown on the Plans Boyle 103065 Standard Provisions - 4 or established by the District's Representative, or any extra work done with- out written authority, will be considered as unauthorized and will not be paid for. Work so done may be ordered removed at the Contractor's expense. Upon failure on the part of the Contractor to comply promptly with any order of the District's Representative made under the provisions of this Article, the Dis- trict's Representative shall have authority to cause defective work to be re- medied or removed and replaced, and unauthorized work to be removed, and to deduct the costs from any monies due or to become due the Contractor. (i) Temporary Suspension of Work; The District's Representative shall have the authority to suspend the work wholly or in part for such time as he may deem necessary due to the failure on the part of the Contractor to carry out orders given, or to perform any provisions of the Contract. The Contractor shall immediately comply with the written order of the District's Represent- ative to suspend the work wholly or in part. The work shall be resumed when methods or defective work are corrected as ordered or approved in writing by the District's Representative. In the event that a suspension of work is ordered as provided above, such sus- pension of work shall not relieve the Contractor of his responsibility to com- plete the work within the time limit specified, and shall not be considered cause for extension of the time for completion, and further, such suspension of work shall not entitle the Contractor to any additional compensation. (j) Errors or Discrepancies Noted by Contractor: If the Contractor, either before commencing work or in the course of the work, finds any discrepancy between the Specifications and the drawings, or between either of them and the physical conditions at the site of the work, or finds any error or omission in any of the drawings or in any survey, he shall promptly notify the District's Representative in writing of such discrepancy, error or omission. If the Con- tractor observes that any drawings or Specifications are at variance with any applicable law, ordinance, regulation, order or decree, he shall promptly notify the District's Representative in writing of such conflict. The District's Representative, on receipt of any such notice, shall promptly investigate the circumstances and give appropriate instructions to the Con- tractor. Until such instructions are given, any work done by the Contractor, either directly or indirectly after his discovery of such error, discrepancy or conflict, will be at his own risk and he shall bear all costs rising there- from. (k) Equipment; The Contractor must furnish adequate equipment to perform properly the work in a workmanlike manner in accordance with these Specifica- tions. Such equipment must be in a good state of repair and maintained in such state during the progress of the work.

All drawings must be marked with the name of the project and the name of the Contractor and be numbered consecutively. All drawings must be complete in every respect. The Contractor shall make such corrections as shall be required by the Engineer and receive the Engineer's stamp of approval before commencing the work in- volved. If the shop drawings show variations from the Contract requirements because of standard shop practices or other reasons, the Contractor shall make specific mention of such variations in his letter of transmittal in order that (if acceptable) suitable action may be taken for proper adjustment of the Con- tract; otherwise, the Contractor will not be relieved of the responsibility for executing the work in accordance with the Contract, even though the shop drawings have been approved. Approval of shop drawings will be general and shall not relieve the Contractor from the responsibility for proper fitting and construction of the work, nor from furnishing the material and work required by the Contract which may not be indicated in the shop drawings when approved; neither does it relieve him from responsibility for errors in shop drawings. SECTION IV - CONTROL OF MATERIAL (a) Quality of Materials: All equipment, materials and supplies to be incor- porated in the work shall be new unless otherwise specified. Unless otherwise specifically provided for in the Specifications, all workmanship, equipment, material and articles incorporated in the work covered by the Contract are to be of the best available grade of their respective kind. Whenever in the Spec- ifications, any material, process or article is indicated or specified by grade, patent or proprietary name, or by name of manufacturer, such specification shall be deemed to be used for the purpose of facilitating description of the materials, process or articles desired, and shall be deemed to be followed by the words "or approved equal", and the Contractor may offer any material or process which shall be substantially equal or better in every respect to that so indicated or specified; provided, however, that if the material, process or article offered by the Contractor is not, in the opinion of the Engineer and/or District's Representative, substantially equal or better in every respect to that specified, then the Contractor must furnish the material, process or article specified or one that in the opinion of the Engineer and/or District's Representative is the substantial equal or better thereof in every respect. In the event that the Contractor furnishes the material, process or article better than that specified, the difference in cost of such material, process or article so furnished shall be borne by the Contractor. (b) Samples and Tests; At the option of the District's Representative the source of supply of each of the materials shall be approved by the District's Representative before delivery is started and before such material is used in the work.

If such objects are injured or damaged by reason of the Contractor's opera- tion, they shall be replaced or restored, at the Contractor's expense, to a condition as good as when the Contractor entered upon the work, or as good as required by the Specifications, if any such objects are a part of the work being performed. The fact that any such pipe or other underground facility is not shown on the Plans shall not relieve the Contractor of his responsibility under this article. It shall be the Contractor's responsibility to ascertain the exist- ence of any underground improvements or facilities which may be subject to damage by reason of his operations. (f) Responsibility for Damage; The District, the Board of Directors, the Engineer and their authorized assistants shall not be answerable or accountable in any manner for any loss or damage that may happen to the work or any part thereof, or for any material or equipment used in performing the work, or for injury or damage to any person or persons, either workmen or the public, or for damage to adjoining property from any cause whatsoever during the progress of the work, or any time before final acceptance of the work.

(i) Mutual Responsibility of Contractors; If through acts of neglect on the part of the Contractor, any other contractor or any subcontractor shall suffer loss or damage on the work, the Contractor agrees to settle with such other contractor or subcontractor by agreement or arbitration, if such other contractor or subcontractor will so settle. If such other contractor or sub- contractor shall assert any claim against the District on account of any dam- age alleged to have been so sustained, the District shall notify the Contractor, who shall indemnify and save harmless the District against any such claim. The Contractor must ascertain to his own satisfaction the scope of the project and the nature of any other contracts that have been or may be awarded by the Dis- trict in the prosecution of the project, to the end that the Contractor may perform this Contract in the light of such other contracts, if any. Nothing herein contained shall be interpreted as granting to the Contractor exclusive occupancy of the site of the project. The Contractor shall not cause any unnecessary hindrance or delay to any other contractor working on the project. If the performance of any Contract for the project is likely to be interfered with by the simultaneous performance of some other contract or contracts, the District, through its representative, shall decide which Boyle 103065 Standard Provisions - 10 contractor shall cease work temporarily and which contractor shall continue, or whether the work under the contracts can be coordinated so that the con- tractors may proceed simultaneously. On all questions concerning conflict- ing interests of contractors performing related work, the decision of said District's Representative shall be binding upon all contractors concerned and the District shall not be responsible for any damages suffered or extra costs incurred by the Contractor resulting directly or indirectly from the award of performance or attempted performance of any other contract or contracts on the project, or caused by a decision or omission of the District respecting the order of precedence in the performance of the Contract. (j) Notice and Service Thereof; Any notice required or given by one party to the other under the Contract shall be in writing and shall be dated and signed by the party giving such notice or by a duly authorized representative of such party.

Nothing contained in this article, however, shall defeat or impair the right of such persons furnishing materials or labor under any bond given by the Contractor for their protection, or any right under any law permitting such persons to look to funds due the Contractor, in the hands of the District. The provisions of this article shall be inserted in all subcontracts and material contracts, and notices of its provisions shall be given to all persons furnishing materials for the work when no formal contract is entered into for such materials.

In the event of any such termination, the District shall immediately serve written notice thereof upon the surety and the Contractor, and the surety shall have the right to take over and perform the contract; provided how- ever, that if the surety within fifteen (15) days after the serving upon it of a notice of termination does not give the District written notice of its intention to take over and perform the Contract, the District may take over the work and prosecute the same to completion by contract or by any other method it may deem advisable for the account and at the expense of the Con- tractor, and his surety shall be liable to the District for any excess cost or other damage occasioned the District thereby; and in such event the Dis- trict may, without liability for so doing, take possession of and utilize in completing the work such materials, appliances, plants and other property be- longing to the Contractor that may be on the site of the work and be necessary therefor. The foregoing provisions are in addition to and not in limitation of any other rights or remedies available to the District. (m) Prohibitive Interests: No officer of the District who is authorized in such capacity and on behalf of the District to negotiate, make, accept, or approve, or to take part in negotiating, making, accepting or approving any architectural, engineering, inspection, construction or material supply con- tract or any subcontract in connection with the construction of the project, shall become directly or indirectly interested personally in this Contract or any part thereof.

SECTION VI - PROSECUTION AND PROGRESS (a) Subcontracting; Specialty subcontractors shall be utilized for the per- formance of such part of the work under this Contract as under normal con- tract practices are performed by specialty subcontractors, unless the Dis- trict determines that the general Contractor has heretofore customarily per- formed such specialty work with his own organization and is equipped to do so, or unless the District determines that the performance of specialty work Boyle 103065 Standard Provisions - 12 by specialty contractors will result in increased cost or inordinate delays, provided however, that the Contractor shall not subcontract any work to be performed or any materials to be furnished in the performance of this Con- tract without the prior written consent of the District. If the Contractor shall subcontract any part of this Contract, the Contractor shall be as fully responsible to the District for the acts and omissions of his subcontractor and of the persons either directly or indirectly employed by his subcontractor as he is for the acts and omissions of persons directly employed by himself. Nothing contained in the contract documents shall create any contractural re- lationship between any subcontractor and the District. The Contractor shall bind every subcontractor (and every subcontractor of a subcontractor) to be bound by the terms of the contract documents as applicable to his work, un- less specifically noted to the contrary in the subcontract in question, ap- proved in writing as satisfactory to the District.

The Contractor shall immediately comply with the written order of the District's Representa- tive to suspend the work wholly or in part. The work shall be resumed when methods or defective work are corrected as ordered or approved in writing by the District's Representative. In the event that a suspension of work is ordered as provided above, such suspension of work shall not relieve the Contractor of his responsibility to complete the work within the time limit specified, and shall not be considered cause for extension of the time for completion, and further, such suspension of work shall not entitle the Contractor to any additional compensation. Boyle 103065 Standard Provisions - 13 SECTION VII - ESTIMATES AND PAYMENTS (a) Partial Payments; The District shall on or before the tenth (10th) day of each calendar month after actual construction work is started, except in case of final estimate hereinafter provided, cause an estimate in writing to be made by the District's Representative of the total amount of the work done and materials furnished by the Contractor and incorporated into the work to the first (1st) day of the month in which the estimate is made. In estimating such value, the District's Representative may take into considera- tion, along with other facts and conditions deemed by him to be proper, the ratio of the difficulty of the work done to the probable difficulties of the work to be done. The District shall retain ten percent (10%) of such esti- mated value as part security for the fulfillment of the Contract by the Con- tractor, and shall within fifteen (15) days after the preparation of such estimate pay to the Contractor the balance of such estimated value after de- ducting therefrom all previous payments and all sums to be kept or retained under the terms of the Contract. (b) Final Payment; The District's Representative shall, after the satis- factory completion of the work, make a final estimate of the amount of work done thereunder and the value of said work, and the District shall pay the entire sum so found to be due after deducting therefrom all previous payments and all amounts to be retained under the provisions of the Contract. All prior partial estimates and payments shall be subject to correction in the final estimate and payment. The final payment shall not be due and payable until the expiration of thirty-five (35) days from the date of acceptance of the work by the District. No certificate given or payment made under the Contract, except the final certificate or final payment, shall be conclusive evidence of the perform- ance of the Contract, either wholly or in part, and no payment shall be con- strued to be an acceptance of any defective work or improper materials. (c) Payments to be Made by Contractor; The Contractor shall pay: (1) For all transportation and utility services, not later than the twenty-fifth (25th) day of the calendar month following that in which said services are rendered. (2) For all materials, tools and other expendable equipment to the extent of ninety percent (90%) of the cost thereof, not later than the twenty-fifth(25th) day of the calendar month following that in which said materials, tools and equipment are delivered at the site of the project, and the balance of the cost thereof not later than the thirtieth (30th) day following the completion of that part of the work in or on which such materials, tools and equipment are incorporated or used. (3) To each of his subcontractors within five (5) days following each payment to the Contractor, the respective amount allowed the Contractor on account of the work performed by his subcontractors, to the extent of each subcontractor's interest therein. Boyle 103065 Standard Provisions - 14 (d) District's Right to Withhold Certain Amounts and Make Application Thereof! In addition to the amount which the District may retain under the above, the District may withhold a sufficient amount or amounts or any payment otherwise due to the Contractor as in its judgment may be necessary to cover: (1) Payments which may be past due and payable for just claims against the Contractor or any subcontractors, for labor or materials furnished in or about the performance of the work on the project under this Con- tract. (2) For defective work not remedied. (3) For failure of the Contractor to make proper payments to his sub- contractors. (4) For amounts claimed by the District as liquidated damages or other offsets. The District may apply such withheld amount or amounts to the payment of such claims in its discretion. In so doing, the District shall be deemed the agent of the Contractor and any payments so made by the District shall be considered as a payment made under the Contract by the District to the Contractor, and the District shall not be liable to the Contractor for such payment made in good faith. Such payments may be made without prior judicial determination of the claim or claims. The District will render to the Contractor a proper account of such funds disbursed in behalf of the Contractor.

SECTION VII - SALVAGE AND INSTALL EXISTING 10" PLUG VALVE A. General; The existing 10" plug valve shall be removed and reinstalled at Station 7+65.02 as shown on the Plans at the same time as the connections are being made to the 20" main. B. Materials and Workmanship; The Contractor shall take care in salvaging the existing 10" plug valve to avoid damage to the valve. If in the opinion of the District Representative any portion of the valve is damaged by the Contractor so as to impair its utility, it shall be repaired with new parts at the Contractor's expense. The Contractor shall have at the site a 10" blind flange to install temporarily if the valve is damaged and cannot be repaired in place. Removal of the valve may be effected by cutting of the existing pipe if necessary. B-l. Valve Box and Valve Box Cover; The valve box and valve box cover shall be salvaged and reinstalled in the same position relative to the valve as now exists. Before backfilling over the valve box the Contractor shall notify the Districts Representative and allow sufficient time for him to cause remote tie monuments to the valve to be set. Any part of the valve box and cover damaged during salvage shall be replaced in kind by and at the Contractor's expense. The gate valve box cover shall be thoroughly cleaned and painted yellow with one coat of Dutch Boy Nalco synthetic finish paint, Dupont Dulux metal protective paint, or approved equal. Carlsbad MWD 62-5200-00-00 Detail Specifications - 4 CARLSBAD MUNICIPAL WATER DISTRICT STANDARD SPECIFICATIONS FOR EARTHWORK (WATER MAINS) A. General: A-l. Earthwork shall consist of performing all operations to clear, grub, excavate, backfill, and replace pavements for the installation of pipe- lines and appurtenances. Earthwork shall include the removal of water and all materials of whatever nature. A-2. Scope of Work; The Contractor shall provide all labor, materials, tools, and equipment necessary to complete all of the earthwork as required. A-3. Earthwork and repairs in City and County and State rights of way shall be done in accordance with requirements and provisions of the permits issued by those agencies in addition to the requirements of these Standard Specifications. If a permit is not required, earthwork and repairs shall conform to the standards of the agency in whose right of way the work is done in addition to the requirements of these Standard Specifications. A-4. Relative compaction specified herein shall be a percentage of the maximum density at optimum moisture content as determined by AASHO Test No. T99-49 Modified (3 layers - 25 blows per layer - 10 Ib. hammer - 18-inch drop - 4-inch diameter - 1/30 cubic foot cylindrical mold). A-5. Safety precautions shall be observed in all phases of the work. Included shall be trench shoring, bracing, lighting, and barricades as dictated by reason and by the Safety Orders of the Division of Industrial Safety, State of California. A-6. Obstructions; The Contractor's attention is directed to the possible existence of pipe and other underground improvements which may or may not be shown on the Plans. The Contractor shall preserve and protect any such improvements whether shown on the Plans or not. Where it is neces- sary to remove and replace or to relocate such improvements in order to prosecute the work, they shall be removed, maintained and permanently replaced by the Contractor at his expense. B. Materials and Workmanship; B-l. Clearing and Grubbing; All brush, roots, vegetation, rubbish, debris, and other deleterious material shall be removed and disposed of so as to leave the construction site clean and neat. B-2. Trench excavation for pipelines, fittings, valves and appurtenances shall be as follows: Carlsbad MWD 080966 Earthwork (Water Mains) - 1 Minimum trench width shall be; Nominal Inside Pipe Diameter Trench Width 4" through 12" Outside diameter plus 12" 14" through 24" Outside diameter plus 16" 27" through 36" Outside diameter plus 20" Where shoring or encasement is required, trench widths shall be increased accordingly. Trench depth shall be adequate to accommodate the pipe and its foundation at the profile shown on the Plans. In the absence of such profile grade, the top of pipe grade shall be located 3 feet below the centerline street grade or 2-1/2 feet below existing ground at the pipe location, whichever is lower. Pipe subgrade at the trench bottom shall have a flat or semi-circular cross section. The bottom of the trench for steel pipe shall be graded and prepared to provide a firm and uniform bearing throughout the entire length of each joint except for required "bell holes" at joints. Steel pipe shall not be laid on earth mounds. Asbestos-cement pipe shall be laid on compacted earth mounds located at one-fifth of the pipe length from one end. Asbestos-cement couplings shall not rest on the trench bottom. Foundations in poor soil shall be constructed by removing all soft, spongy, and deleterious materials below pipe bottom grade to a depth determined by the District's Representative. The void shall then be backfilled to pipe grade and cross section with sand compacted to a minimum relative compaction of 90%. The replacement of unsound materials to depths of 2 feet below bottom of pipe grade shall be considered part of the work. Replacement of materials greater than 2 feet of depth will be paid for as extra work. Foundations in rock shall be constructed by removing rock to a minimum depth of 6 inches below bottom of pipe grade and backfilling with sand compacted to a minimum relative compaction of 90%. Correction of Faulty Grades; All excavations carried below pipe grade shall be backfilled to proper grade and cross section with sand compacted to a minimum relative compaction of 90%. B-3. Backfill; All trenches and excavations shall be backfilled after pipe, fittings, valves and appurtenances have been installed. B-3.1 Procedure in Pipe Zone; The pipe zone shall be considered to extend from the bottom of the excavation to 8 inches above the top of the pipe. Backfill material from the bottom of the excavation to the mid-point of the pipe or to a height of 12 inches above the bottom of the pipe, Carlsbad MWD Earthwork (Water Mains) - 2 whichever is lower, shall be sand (except for the earth mounds on which asbestos-cement pipe is laid). Sand shall be free from foreign materials such as dirt, rocks, sticks, vegetation, etc. and shall be so graded that not more than 10% by weight shall pass a No. 200 sieve. Backfill material for the remainder of the pipe zone shall be sand or loose soil free from stones, clods, and other deleterious material. Backfill shall be placed in layers simultaneously on each side of the pipe for the full width of the trench. Sand may be placed and compacted in layers up to 12 inches in compacted thickness* All other material shall be placed and compacted in layers not exceeding 6 inches in compacted thickness. In placing and compacting the backfill, particular attention is to be given to the underside of the pipe and fittings to provide a firm support along the full length of the pipe. Care shall be exercised in backfilling to avoid damage to the pipe coating. B-3.2 Procedure Above Pipe Zone; From the top of the pipe zone to the ground surface or finish grade, the material for backfill shall conform to that specified for the pipe zone except that it may con- tain stones up to 8 inches in diameter but shall be so graded that at least 40% of the material passes a No. 4 sieve. The coarser materials shall be well distributed throughout the finer material. Backfill material shall be placed in layers of a thickness which can be compacted throughout to the specified density with compaction equipment which will not damage the pipe and fittings. B-3.3 Densification; All backfill shall be compacted throughout by tamping or water settling to a minimum relative compaction of 90% or to the density required by the agency in whose right of way the work is located, whichever is the more compact. Tamping Method; Backfill material shall be placed in uniform layers of the thickness specified above. The moisture content of the back- fill material shall be near or at the optimum required for compaction and each layer shall be tamped until compacted to the required mini- mum relative compaction. Heavy duty compacting equipment having an overall weight in excess of 125 pounds shall not be used until backfill has been completed to a depth of 2 feet over the top of pipe. Water Settling Method; This method may not be used when in the opinion of the District's Representative (1) the backfill material is not sufficiently granular to consolidate properly by this method, (2) the adjacent soils are not sufficiently pervious to permit the water to drain away, or (3) adjacent soils or nearby structures may be damaged. Carlsbad MHD 080966 Earthwork (Water Mains) - 3 In the pipe zone, the backfill material shall be placed in uniform layers of the thickness specified above. At the top of each layer, the trench shall be diked at suitable intervals depending on the slope, and the trench between dikes shall be filled with sufficient water to inundate the backfill materials. The backfill material shall then be agitated to promote its consolidation. Care shall be exercised to prevent floating the pipe. Following backfilling of the pipe zone, the trench shall be diked at suitable intervals depending upon slope, and the trench between dikes shall be filled and maintained with sufficient water so that backfill materials subsequently placed will be inundated during and following placement. The water level shall be controlled to pre- vent floating of the pipe. Backfill materials above the pipe zone shall be placed in the water-filled trench in uniform layers not exceeding 18 inches in thickness. B-4. Excess Excavated Material; The Contractor shall make the necessary arrangements for and shall remove and dispose of all excess excavated material. In open terrain, surplus material may be disposed of within the right of way by spreading, provided that rocks or lumps which cannot be readily covered by spreading are removed. B-5. Final Clean-Up; After backfill has been completed, the right of way shall be dressed smooth to the contour of the original ground and left in a neat and presentable condition, free of all cleared vegetation, rubbish and other construction wastes. Rocks and lumps which cannot be readily covered by spreading shall be hauled away and disposed of by the Contractor. On slopes where, in the opinion of the District's Representative, rainfall runoff would create an erosion problem, the Contractor shall excavate at approximately 100-foot intervals V-type interception ditches to collect and carry runoff to the low side of the right of way. The interception ditches shall be approximately 1-foot deep and shall be skewed approxi- mately 45 degrees with the centerline of the right of way. C. Payment; Payment for earthwork and for conforming to all the provisions included herein shall be considered to be included in the contract unit or lump sum prices paid for the various items of work, and no additional allowance will be made therefor.

The working areas shall be confined so as not to obstruct roadways, drive- ways, and sidewalks and so that not more than one lane of traffic shall be closed at any time, unless specific permission is granted otherwise. Temporary roadways, driveways, and walks for vehicles and pedestrians shall be constructed where required. Upon written application to the Construction Engineer, streets, driveways, or areas may be closed for limited periods where, in the opinion of the Road Commissioner, the public interests can best be served thereby. No trench shall be excavated until all the pipe or other material to be installed in the excavation is on the site. The backfill shall be placed within forty-eight (48) hours after the trench has been cut to grade and pre- pared to place the utility, unless prior permission has been given in writing by the Road Commissioner or his Representative to permit the trench to remain open. E. Inspection; All work shall be subject to inspection by representatives of the County Surveyor and Road Commissioner. Any unsatisfactory work shall be corrected whenever discovered, even if occurring after the completion of the work. Upon failure of the permittee to comply promptly with any order of the Road Commissioner made under this permit, the Road Department may cause rejected or unauthorized work (other than the utility or structure itself) to be remedied, removed or replaced and the costs thereof charged to the permittee. Deviations other than specified tolerances from the approved plans and work- ing drawings,as may be required by the exigencies of construction, will, in all cases, be determined by the Road Commissioner and authorized only when in writing. F. Preservation of Monuments Within Roadway: Where plans are submitted, it shall be the responsibility of the Engineer of the Work to show all monuments of record which may be necessary to move. The permittee shall not disturb any monuments of record found on the line of the improvements without permission of the County Surveyor, and the per- mittee shall bear the expense of resetting any monuments or stakes which may be disturbed. G. Restoration of Existing Improvements; When, during the progress of work, it becomes necessary to remove any existing pavement, sidewalk, curb, land- scaping, culvert, or other existing improvements, the permittee shall replace or restore the improvement required by such work in a manner that will restore the improvements as nearly in their original location and condition as is reasonably possible. 060964 Excavation Permit - 2 of 10 H. Notice to Permittee; Written notice of inspections and of any imperfec- tions in the work delivered to the permittee's agent in charge of the work shall be considered as notice to the permittee. I. Lights., Barriers, Warning Signals; The permittee shall take all necessary measures to protect the traveling public during the construction. As pre- scribed in Section 71.322, Chapter 111, Title 7, San Diego County Code, he shall place and maintain warning lights and barriers at each end of any excavation or obstruction, and at distances of not more than fifty (50) feet apart, along such excavation or obstruction. Obstruction lights shall be on from sunset each day to sunrise of the next day, until such excavation is entirely refilled or such obstruction is removed. Said barriers shall not be less than three (3) feet in height. On all projects involving excavations or obstructions which encroach to within four (4) feet of the through-traffic lane, a reflectorized "Road Con- struction Ahead" sign shall be installed at least 300 feet in advance of the work area. This sign shall be a standard C-18-R, as adopted by the California Division of Highways. Other signs, as deemed necessary, may be required throughout the project, and all signs shall conform to the Regulations adopted by the California Division of Highways pursuant to Section 21406 of the California Vehicle Code. NOTE: Superseded Signs; Until January, 1965 the "OLD" standard type signs such as PR reflectorized "CONSTRUCTION ZONE - DRIVE CAREFULLY" may be used. j. Traffic Control; When permission is granted to reduce traffic to a single lane for an appreciable distance, or where it is necessary to stop or divert traffic for any reason, flagmen shall be used. Flagmen shall be properly dressed with standard flagmen's clothing and equipped so that they are easily recognizable and shall be properly trained to guide drivers. Operations of the permittee or contractor shall not cause a public road to become impassable for longer than thirty - (30) minute intervals, unless he is specifically authorized in writing by the County Road Department Construction Engineer. If operations of the contractor do cause a public road to become impassable, but for no longer than thirty - (30) minute intervals and where a detour is not practical, he shall post and maintain at both ends of the work a 4' x 5' sign to read in large letters, "WARNING - CONSTRUCTION WORK, TRAFFIC SUBJECT TO A 30-MINUTE DELAY". If traffic delays of more than thirty - (30) minutes are anticipated, the contractor shall provide a detour. All signs to be used on a County Road shall be furnished and placed in con- formance with the Planning Manual of Instruction, Part 8, Traffic of the Department of Public Works, Division of Highways, State of California. (Reference is here made to a Pamphlet entitled "Traffic Interference Control Manual", published by cooperation of the County of San Diego, City of San Diego, Pacific Telephone and Telegraph Company and San Diego Gas & Electric Company, as a manual designed as a convenient reference guide for construction and maintenance foremen in an effort to standardize methods of keeping traffic flowing safely with a minimum of delay.) Its suggestions are to be followed wherever feasible. 060964 Excavation Permit - 3 of 10 K, Detours; If the construction work requires a detour, written permission shall be obtained from the Traffic Engineer of the County Road Department prior to establishment. The request for such a permit shall be made in writing and processed via the Construction Engineer. At the beginning and end of a detour, signs shall be erected notifying of the detour and the direction of the traffic flow. These signs shall be similar to Standard Type C-5-R of the California Division of Highways and shall be at least 18 inches high by 48 inches long, black background with the word "DETOUR" in black letters 5 inches high on a white arrow to indicate the direction. These signs shall be reflectorized. Detour signs shall be placed on barricades at each intersection along the entire route. L. Excavation; All earthwork shall be performed in conformance with Section 19 of the Standard Specifications and these Special Provisions. L-l. Maximum Length of Trenching Operations; Trenching operation includes all work between the point of excavation and the point where the trench has been resurfaced and opened for traffic. The maximum length of trench which may be opened at any one time may vary for specific locations be- cause of the local traffic volume or importance of the street. In general, the following maximum openings will be allowed, if the traffic is cared for. These allowable lengths may be shortened when considered necessary for the protection of the public, in the opinion of the Road Commissioner. L-l.l Where the trench is cut along and under traffic lanes in streets or alleys, and where width of trench exceeds 28 inches and the depth exceeds 5 feet, at no time shall more than 2,000 feet of trench be under construction in any one work area, and all work operation in one area shall be confined to not more than 750 feet of trench opened and incompletely backfilled. The remainder of the area of trenching operation shall be available for safe vehicular and pedestrian traffic at all times. L-l.2 Where width and depth of the excavation do not exceed 28 inches and 5 feet, respectively, or where the work area is outside the traffic lanes, 4000 feet of trench may be under construction in any one work area. In such an area, there shall not be more than 1400 feet of trench opened and incompletely backfilled. The re- mainder of the area of trenching operation shall be available for safe vehicular and pedestrian traffic at all times. L-l. 3 Only when the contractor has entirely separate and complete crews, each of which is capable of doing the entire job in their area, will two or more operations be considered separate work areas. L-l.4 Trench covered with temporary surfacing will be considered as open to traffic. Temporary surfacing shall conform to provisions of Paragraph 14 of these Special Provisions. L-2. Blasting; In the event that blasting is necessary in excavation, a permit to receive and transport and a burning and blasting permit shall be obtained as required by the Health and Safety Code, the Motor Vehicle 060964 Excavation Permit - 4 of 10 Code, and the Public Resources Code. The blasts shall be blanketed with mats or other approved protection to avoid damage or injury to the Public. Signs warning of blasting area and requesting that Radio Transmitters not be used in the blasting area shall be furnished and placed by the permittee. All blasting shall be performed in compliance with the Re- quirements of the State of California "General Industry Safety Orders". L-3. Excavated Material; Excavated material shall be deposited along the trench side in a manner that will not obstruct the traffic lane or cause undue inconvenience to the traveling public. If the roadway section is not sufficient to adequately maintain through traffic, the permittee or contractor may be required to contain or remove the spoil material. M. Backfill; Backfill shall conform to Section 19-3.06 of the Standard Specifications, except that Method "B" will not be permitted, and the follow- ing modifications shall apply: M-l. Backfill Around Utility; The Specifications of the Utility Company or Utility District may be used where approved as a condition of the permit by the Permit Engineer, except that where no specifications are submitted or where the specifications of the Utility Company are not approved as a condition of the permit, the following specifications shall govern: Backfill around the pipe or utility, and to one foot above the top of the pipe shall be a granular material, sand or fine earth, 100% passing the 3/4" sieve and compacted to the density required in Paragraph 13-D for the depth at which the pipe is laid. In no event shall this relative density be less than 85%. M-2. Backfill to Subgrade; From one (1) foot above the top of the pipe to the subgrade of the roadway section, the material for backfill may be trench spoil which shall not contain clods that will not readily dis- integrate in water, nor stones larger than six (6) inches maximum dia- meter. This layer may contain stones, broken concrete, bituminous pavement or oil cake ranging in size up to six (6) inches maximum dia- meter in quantity not exceeding twenty-five (25) percent of the volume when such coarse materials are well distributed throughout the finer material. M-3. Backfill Subgrade to Pavement; When the structural section for the roadway shows base or subbase material (D.G. or Decomposed Granite shall be assumed to mean aggregate subbase), it shall be replaced in kind, except that the minimum section, or when there is no definite structural section available shall be six (6) inches of Class III Aggregate Base furnished and placed in conformance with Sections 26 of the Standard Specifications and the following modifications: 060964 Excavation Permit - 5 of 10 Sand Equivalent 30 Minimum Resistance (R) Value 75 Minimum Sieve Grading 3/4" Maximum As follows: Sieve Size % Passing 3/4 100 No. 4 80-100 No. 30 30-60 No. 200 5-15 When the R Value is 75 or greater, the minimum asphalt concrete or paving cover shall be as specified in Paragraph 15. In the event the base material delivered on the job site has an R Value less than 75, but greater than 70, it may be left in place on the job, but its reduced structural strength shall be compensated for by providing an additional one-half (1/2) inch of asphalt surfacing, and these sections shall be considered to be structurally equal. In event the R Value of the material is less than 70, it shall be removed from the project and replaced with suitable material. M-4. Compaction; The Permittee shall have his compaction equipment on the project, and the equipment shall be approved by the Construction Engineer before backfilling is started. All base and subbase material shall be compacted to 95% relative density. Below subbase or base to a trench depth of five (5) feet measured from the top of the surfacing (pavement), the backfill shall be compacted to 90% relative density. Below five feet measured down from the top of the surfacing, the backfill shall be compacted to 85% relative density. All densities shall be determined in accordance with the latest revision of California Test Method No. 216. Compaction tests will be taken through- out the project to determine whether the specified requirements have been met. The number of tests and their location and depth shall be left to the discretion of the Construction Engineer. The Permittee shall excavate holes required for compaction tests at locations designated by the Construction Engineer and under his direction, and shall refill and recompact these to the densities required by these Specifications for the depth tested. In areas outside the slope lines, in the median area, and not beneath any roadway or shoulder, when stated on the Excavation Permit, or approved by the Engineer, the compaction may be reduced to a minimum of eighty-five (85) percent. The Permittee may backfill using any of the methods indicated below, if approved by the Engineer. 060964 Excavation Permit - 6 of 10 M-4.1 Tamping Methods; When machine tamping, hand tamping or hand-operated methods are used, the moistened fill material shall be tamped in uniform layers not to exceed eight (8) inches in thickness, loose measurement, unless otherwise approved in writing by the Engineer. M-4.2 Water Methods; When flooding or ponding method is used, the trench shall be diked at suitable intervals, depending on the grade of the ditch. The depth of water must be such that when earth or sand is shoveled or pushed into the trench, it will become completely saturated. Ponding and jetting will be done in con- formance with Section 19-3.06 of the Standard Specifications. After the trench has been initially filled and knocked down by water settling, further ponding or jetting will not be permitted in the upper two feet of the trench. NOTE; (a) If the Permittee agrees in writing to place a temporary fill and temporary surfacing and to return in a specified time to rebuild the trench as necessary and to remove the temporary surfacing and to replace it with a permanent cover,as required in Paragraph 15, the Construction Engineer may authorize the option of jetting the complete trench depth and providing temporary cover. (b) However, if the Construction Engineer determines that the water method will soften or damage the existing roadway, or that the material proposed for water settling is unsatisfactory for that purpose, water settling will not be permitted. M-5. Backfill Under Obstructions; When an obstruction or other utility or structure is encountered and the new utility must pass under it, the area between the two utilities shall be backfilled with subbase material, sand or gravel, free from large clods, large stones, adobe, or any deleterious matter, and shall be rammed with proper tools until thoroughly compacted to the density of the adjacent material. M-6. Bored and Jacked Crossing; Where as a condition of a permit, an open cut is not permitted, a 1/4-inch thick wall, steel casing or pipe, with an inside diameter of at least six (6) inches greater than the maximum diameter of the utility shall be jacked under the road, except that when a pipe of sufficient strength to be jacked under the road is used, the steel casing will not be required, when approved by the Engineer. While the utility is being placed or after it is in place, the area between the casing and the new pipe shall be filled with sand. The length of the bored crossing shall be designated as a condition of the permit. M-7. Special Circumstances; On streets in commercial areas, urban type development, or having high traffic counts (5,000 cars per day or greater), the convenience and safety of the traveling public may require a higher type backfill which is installed rapidly and surfaced immediately. In such circumstances, trench spoil will not be allowed as backfill material. The backfill material shall be sand compacted by wetting or material 060964 Excavation Permit - 7 of 10 meeting the requirements for untreated rock base placed in loose layers eight inches thick before tamping and compacted to 95% relative density. The use of this paragraph and the time allowed for this "Special Circumstance" backfill will be stated as a condition of the permit. Only emergency work will be allowed in commercial areas between the dates of Thanksgiving and New Year's Day. N. Temporary Surfacing; All trenches across paved traffic lanes shall be provided with temporary surfacing, unless the Permittee immediately installs permanent resurfacing. The minimum requirements for temporary resurfacing shall be steel plating or "Road-Mixed Asphalt Surfacing" conforming to Section 38 of the Standard Specifications, except that the liquid asphalt shall be SC 800, conforming to the latest Specifications of the Asphalt Institute, and shall have a minimum thickness of two (2) inches. Temporary resurfacing shall be placed within twenty-four (24) hours after completion of trench backfill and compaction and shall be properly maintained until permanent surfacing is replaced. The Permittee will not be permitted to mix asphalt surfacing in the traveled way unless authorized in advance by the Construction Engineer. The Permittee shall control dust, as directed by the Construction Engineer, using methods of Section 10, Standard Specifications. In the rainy season (October to May), when directed by the Construction Engineer, all trenches in paved traffic lanes shall be provided with temporary resurfacing, unless the Permittee immediately installs permanent resurfacing. 0. Resurfacing; 0-1. General; In all streets or alleys in which the surface is removed, broken or damaged by equipment, or in which the ground has caved in or settled, due to the installation of improvements, the surface shall be restored to the original grade and crown section by the Permittee. This shall include areas beyond the actual limits of the trench which may be damaged by equipment or by unusually heavy traffic volume created by the trenching operations. In the absence of specific designation on the Plans, and where the street has been improved with roadway surface, base course, curb, sidewalk or gutter, trenches or damaged sections shall be restored with the type of improvement conforming to that which existed at the time the Permittee entered upon the work. All work shall match the appearance of the existing improvements and finished pavement shall not deviate from existing grade, and shall be free from ruts, depressions and irregularities. In all streets or alleys which are not paved, but are traveled by the public, the surface of the area disturbed by the Permittee's operations shall be replaced to a depth of at least six (6) inches with Class 111 060964 Excavation Permit - 8 of 10 Aggregate Base conforming with Section 26 of the Standard Specifications and as modified in Paragraph 13 (c). Unless otherwise specified in the Excavation Permit, pavement replace- ment shall be as hereinafter specified. 0-2. Portland Cement Concrete Pavement; Portland cement concrete pavement shall be furnished and placed in conformance with Section 40 of the Standard Specifications, except as herein modified. Unless other- wise specified in the Excavation Permit, the concrete shall be "Class "B", conforming to Section 90 of the Standard Specifications. The pavement shall have a thickness equal to that of the existing pavement plus one (1) inch. The existing pavement shall be scored to approximately one-fourth (1/4) its thickness by saw cut along a straight line deviating not more than two (2) inches in twenty (20) feet, and shall be broken out to provide clean, solid, vertical faces, free of loose material. Where large irregular surfaces are removed, such cuts shall be parallel with the center line of the roadway and at right angles to same. Joints shall be constructed to coincide with the existing pavement. The pavement shall be finished true to grade and cross-section and free from irregularities. 0-3. Asphaltic Concrete Pavement; Asphalt concrete pavement shall be Type "B" plant-mixed surfacing, furnished and placed in accordance with Section 39 of the Standard Specifications, except as herein modified. Paving asphalt shall conform to Section 92 of the Standard Specifications and shall be 40-50; 60-70 or 85-100 penetration, as determined by the Engineer. The pavement shall have a thickness equal to that of the existing pavement plus one (1) inch with, in any case, a minimum thickness of two (2)inches. The new asphaltic concrete shall be brought up in maximum lifts of two (2) inches, compacted thickness, the upper lift being rolled with a steel wheel roller. Before placing pavement, edges of existing pavement shall be trimmed or cut to a straight line deviating not more than two (2) inches in twenty (20) feet. Where large irregular surfaces are removed, such trimming or cut shall be parallel with the center line of the roadway and at right angles to same.

Materials and Workmanship; B-l. Cement shall be portland cement Type II, conforming to ASTM Designation: C150. B-2. Aggregates; All aggregates used in grout, mortar, and in concrete shall conform to the provisions of Section 90 of the Standard Specifica- tions of the California Division of Highways dated July, 1964. The maximum nominal size of coarse aggregate shall be 1-1/2 inch. B-3. Water used shall be of potable quality. B-4. Admixtures to prevent segregation and to improve workability or to accelerate the setting of the concrete will be permitted provided the ad- mixture proposed shall first be approved in writing by the District's Representative, and the proportions of the admixture to be used shall be fixed by the District's Representative. B-5. Strength Requirements; All concrete shall be proportioned to attain a minimum cylinder strength of -3,000 psi in 28 days. The compressive strengths are to be determined in accordance with ASTM C39. Not less than 6 sacks of cement shall be used per cubic yard. B-6. Proportioning; The exact proportions of the concrete ingredients shall be established by a material testing laboratory selected by the District's Representative. The Contractor shall notify the District's Representative of his proposed source of aggregate in sufficient advance time to permit the design of the mix. Aggregates shall be proportioned by weight. Cement shall be proportioned by the sack or by weight. B-7. Mixing; The cement, sand and coarse aggregates shall be so mixed and the quantity of water added shall be such as to produce a homogeneous mass of uniform consistency. Each mixer used shall be of the batch type and be of a design to insure uniform distribution of all the materials throughout the mass during the mixing operation, when operated at the speed and capacity recommended by the manufacturer and the mixer shall be so operated. Each mixer shall be so constructed that the District's Representative can conveniently observe the consistency and uniformity of the concrete in the mixer during the operation. Only sufficient water shall be used in mixing any class of concrete to produce a workable mass suitable for the particular type of construction Carlsbad MWD 080966 Portland Cement Concrete - 1 involved. Water shall be added prior to or during the mixer charging operation. The mixing of each batch after all materials have been placed in the mixer shall continue for not less than 90 seconds for a stationary mixer smaller than 2 cubic yards in capacity and for not less than 2 min- utes for a larger stationary mixer. If transit mix concrete is used, the mixing time shall not be less than 3 minutes for each cubic yard of capacity. The mixture shall be con- tinuously agitated until all of the concrete has been discharged from the mixer drum. The total elapsed time between the introduction of water to the batch and depositing the complete mix in the forms shall not exceed 60 minutes for concrete mixed in transit mixers. The manu- facturer's guaranteed capacity of the drum shall not be exceeded. B-8. Placing; Concrete shall be placed only in the presence of the District's Representative and not until all form work, reinforcement, installation of fixtures to be embedded, and preparation of concrete surfaces to be bonded have been inspected and approved by him. Concrete surfaces on or against which other concrete is to be placed shall be thoroughly cleaned of surface laitance and clean aggregate shall be exposed. Abrasive blast cleaning may be required. Each concreting operation shall be continuous until the placing in the course, section or monolith is completed. Fresh concrete shall not be permitted to fall from a height greater than 6 feet without the use of adjustable length pipes or "elephant trunks". In order to assure that there will be no interruption in such continuous placing, the Contractor shall have available standby concrete mixing equipment ready for use in case of breakdown, or he shall make arrange- ments, satisfactory to the District's Representative, with the supplier of the concrete, if transit mix concrete is being used, so that the Dis- trict's Representative may be assured that once placement is started it can be completed without interruption. The vibrating equipment, includ- ing standby equipment, shall be at the site and tested in the presence of the District's Representative during the day preceding the planned day of placement. Appropriate mechanical vibration shall be used in placing concrete to eliminate stone pockets and voids, to consolidate each layer with that previously placed, to completely embed reinforcing bars and other fix- tures, and to bring just enough fine material to the faces of top and exposed surfaces to produce a smooth, dense and even texture. Vibrators shall be of the high frequency internal type and the number in use shall be ample to consolidate the incoming concrete to a proper degree within 15 minutes after it is deposited in the forms. In all cases, at least 2 vibrators shall be available at the site. The use of external vibrators for compacting concrete will be permitted when the concrete is otherwise inaccessible for adequate compaction, provided the forms are constructed sufficiently rigid to resist displacement or damage from external vibra- tion and the vibrators are approved by the District's Representative. Carlsbad MWD 080966 Portland Cement Concrete - 2 B-9. Forms; All forms shall be smooth, mortar-tight, true to the re- quired lines and grades, and of sufficient strength to resist any apprec- iable amount of springing out of shape during the placing of concrete. All foreign matter shall be removed from forms before concrete is placed therein. Forms previously used shall be thoroughly cleaned before re-use. Prior to placing concrete, all forms shall be oiled with a high penetrat- ing form oil which leaves no film on the surface that can be absorbed by the concrete. Immediately prior to placing concrete, all forms shall be thoroughly wetted. Forms shall not be removed until the concrete has hardened sufficiently to safely support its own weight and possible construction loads. Forms supporting concrete members which are subject to direct bending stress shall not be removed or struck until concrete test cylinders show that a strength of not less than 2,500 psi in compression has been attained. In no case, however, shall forms be removed or released prior to the ex- piration of 48 hours following placing of the concrete. Forms for all surfaces which will not be completely enclosed or hidden below the final surface of the ground shall be made of surfaced plywood. Insofar as practicable, forms shall be so constructed that the form marks will conform to the general lines of the structure. All sharp edges shall be chamfered with 1-inch by 1-inch triangular fillets. Form clamps and ties with effective water stops shall be used to maintain accurately the specified wall thicknesses. These ties shall be either of the threaded or snap-off type so that no metal will be left within 1-1/2 inches of the surface of the wall. The use of twisted wire ties will not be permitted. B-10. Openings; Pipe sleeves, inserts for pipe connections, anchors, and forms for pipe holes must be accurately placed and securely fastened to the forms in such a manner that the placing of concrete will not alter their alignment or location. B-ll. Joints; Construction joints shall be made only where shown on the Plans unless otherwise approved by the District's Representative. In case of emergency, construction joints shall be placed as directed by the Dis- trict's Representative. After the pour has been completed to the construction joint and the con- crete has hardened, the entire surface of the joint shall be thoroughly cleaned of surface laitance and clean aggregate shall be exposed by abrasive blast cleaning. Wire brushing and air and water jets may be used while the concrete is fresh provided results equal to abrasive blast cleaning are obtained. Construction joints shall be keyed. Keyways shall be formed by bevelled strips or boards placed at right angles to the direction of shear. Ex- cept where otherwise shown on the Plans or specified, keyways shall be at least 1-1/2 inches in depth over at least 25 percent of the area of the section. Carlsbad MWD 080966 Portland Cement Concrete - 3 When it is necessary to make a joint because of an emergency, reinforc- ing steel shall be furnished and placed across the joint as directed by the Engineer. Furnishing and placing such reinforcing steel shall be at the Contractor's expense and no payment will be made therefor. B-12. Curing: Except as described below, all newly placed concrete shall be kept wet by the continuous application of water for the first 7 days after the concrete has been placed. Concrete surfaces which will be below ground after backfilling and minor structures, such as pipe headwalls, pipe anchor blocks, catch basins, and the like, may be cured by the application of pigmented curing compound. The curing compound shall meet the specifications of AASHO Designation: M 148, Type II, White Pigmented. Application shall be done with hand spraying equipment in a manner satisfactory to the District's Repre- sentative. Surfaces to be cured by the pigmented curing compound method shall be kept moist or wet until the curing compound is applied, and the curing compound shall not be applied until all patching or surface finish- ing has been completed. The pigmented curing compound shall not be applied to the surfaces of construction joints or on reinforcing steel. E-13. Surface Finishes; During the placing of concrete, care shall be taken in vibrating or otherwise consolidating the concrete to insure sur- faces of even texture free from voids. Immediately after the forms have been removed, all form bolts shall be removed to a minimum depth of 1-1/2 inches below the surface of the concrete. All holes and depressions caused by the removal or cutting back of such form bolts shall be cleaned and filled with cement mortar composed of 1 part by volume of cement to 2 parts of sand. The mortar shall contain sufficient white cement to tint the mortar to the shade of the surrounding concrete. Care shall be exer- cised to obtain a good bond with the concrete. All rock pockets and honeycombed areas shall be repaired by chipping back to solid concrete and filling the resulting space in the same man- ner as specified for bolt holes. This work shall be done immediately following the removal of forms. If in the judgment of the District's Representative rock pockets are of such an extent or character as to affect the strength of the structure materially or to endanger the life of the steel reinforcement, he may declare the concrete unacceptable and require the removal and replacement of that portion of the structure. Except for surfaces which are to be buried, all fine and other projections shall be removed and the surfaces shall be brushed with stiff wire brushes or otherwise finished until a uniform color has been obtained. The use of carborundum stones may be required to remove unsightly bulges or discolor- ations. The object of these operations is to obtain smooth, even surfaces of uniform appearance, free from unsightly bulges or depressions due to form marks and other imperfections. The Contractor's attention is called to the fact that the degree of care exercised in building forms and the character of materials used in formwork are the main factors affecting the amount of finishing which will be required. Carlsbad MWD 080966 Portland Cement Concrete - 4 All flat work shall be finished and worked from the poured slab and floated and troweled to a smooth, hard finish. B-14. Reinforcement; Reinforcing bars shall be deformed and shall be either Billet Steel Bars for Concrete Reinforcement, ASTM Designation A-15, or A408, or Rail-Steel Bars for Concrete Reinforcement, ASTM Des- ignation A16. The various grades of steel may not be used interchange- ably in structures. Bars shall not be bent or straightened in a manner that would injure the material. Hooks shall conform to the manual of standard practice of the American Concrete Institute. Main reinforcing bars shall not be spliced except as shown on the Plans. Splices at points of maximum stress shall be avoided. Where bars are spliced, they shall be lapped at least 30 bar diameters and wired to- gether to provide a minimum distance of 2 inches between the splice and the nearest adjacent bar or surface of the concrete. Splices shall be staggered at least 40 bar diameters. Metal reinforcement shall be accurately placed as shown on the Plans and shall be securely held in position by wiring at intersections with No. 16 or larger wire and by using concrete spacers. The minimum spacing center to center of parallel bars shall be three times the diameter, but in no case shall the clear distance between bars be less than 2 inches. All bars shall have a clear coverage of 1-1/2 bar diameters but not less than one inch measured from the surface of the concrete to the outside of the bar. Metal supports may be used provided no portion of the support extends to within 1-1/2 inches of the surface of the concrete. Wooden supports shall not be used. Wire mesh used for reinforcement shall be rolled flat before placing concrete and shall be supported and tied to prevent movement during con- crete placement. Mesh shall conform to ASTM Designation A185. Reinforcement, at the time concrete is placed, shall be free from rust, scale, or other coatings that would destroy or reduce the bond. B-15. Rubber Waterstops; Materials, fabrication, and splices shall conform to the article on Rubber Waterstops in Section 51 of the Standard Specifications of the California Division of Highways dated January, 1960. Stops shall be firmly supported during concrete placement to prevent dis- location and to insure that ends remain at right angles to the construc- tion joints. <• Carlsbad MWD 080966 Portland Cement Concrete - 5 CARLSBAD MUNICIPAL WATER DISTRICT STANDARD SPECIFICATIONS FOR STEEL WATER PIPE AND FITTINGS A.

Excavation and Backfill; Excavation and backfill shall conform to the Standard Specifications for Earthwork. C-2. General Installation Procedures and Workmanship; Prior to laying the pipe, the bottom of the trench shall be graded and prepared to provide uniform bearing throughout the entire length of each joint of pipe. Bell holes of ample dimension shall be dug in the bottom of the trench at the location of each joint to facilitate the joining. The trench shall have a flat or semicircular bottom conforming to the grade to which the pipe is to be laid. The pipe shall be accurately placed in the trench on the prepared foundation to the lines and grades shown on the Plans. Fittings shall be supported independently of the pipe. Deflections at rubber gasket or flexible coupling joints shall not exceed 4 degrees nor that recommended by the manufacturer. Bare cinch or choker type cables shall not be used for handling pipe. Slings for pipe handling shall be belts of sufficient width to prevent damage to the exterior coating. Pipe shall be carefully handled to prevent damage to the lining and coating. No joint shall be backfilled until it has been inspected by the District's Representative. Sufficient trench space shall be left open in the vicinity of each joint to permit visual inspection around the entire periphery of the joint. C-3. Rubber ring joints shall be completed in the trench. The ends of the pipe shall be thoroughly cleaned and positioned for joining. Vege- table soap solution shall be applied to the inside of the bell, and the rubber gasket snapped into the groove on the spigot end. The bell end shall be buttered with cement mortar in such a manner and in sufficient quantity to completely fill the recess between the respective linings of the two joined sections of pipe. The spigot end shall then be entered into the bell end of the adjacent pipe section the distance shown on the shop drawings. Immediately after joining, the pipe interior shall be swabbed to remove all excess mortar by drawing an approved type of swab or squeegee through the pipe. For pipe 24 inches in nominal inside diameter and larger, a 1/2-inch recess between adjacent linings shall be provided and later pointed from the inside with cement mortar and troweled smooth. The outside joint recess shall be grouted with cement mortar after a fabric diaper has first been placed around the joint and tightened se- curely to prevent leakage while the mortar is being poured. The diaper shall be made of heavy duty sail cloth of sufficiently close weave to Carlsbad MWD 080966 Steel Water Pipe and Fittings - 5 prevent cement loss from the mortar. The fabric shall be hemmed on each edge and shall contain a metal strap within each hem sufficiently longer than the circumference of the pipe to allow a secure attachment of the diaper to the pipe. The diaper width will depend on pipe size and design and shall be the width recommended by the manufacturer. Following installation of the diapers, the joints shall be poured and rodded from one side only until the mortar comes up to the top of the diaper on the opposite side. Approximately one hour subsequent to the pouring of the joint, the joint shall be rechecked and if any settlement, leakage, or shrinkage has taken place, the joint shall be refilled with mortar. The joint shall be stripped, repaired if necessary, and given a heavy coating of curing compound at the earliest practicable time after the mortar has hardened sufficiently. Joint mortar shall be protected from direct sunlight for at least 14 days by covering with burlap or heavy paper unless backfilled prior to the expiration of the 14 day period. Water shall not be turned into the pipe until 36 hours after placing joint mortar. C-4. Welded joints shall be completed in the trench. When the pipe is being laid, both the spigot and the bell ends shall be thoroughly cleaned of all foreign matter and all protective material shall be removed from the surfaces that are to be in contact at the joints. Just prior to joining the two ends together, each end of the pipe shall be"buttered" with cement mortar in such a manner and in sufficient quantity to completely fill the space between the respective mortar linings. After the joining is completed, the pipe interior shall be swabbed to remove all excess mortar by drawing an approved type swab or squeegee through the pipe. For pipe 24 inches in nominal inside diameter and larger, a 1/2-inch recess between adjacent linings shall be provided and later pointed from the inside with cement mortar and troweled smooth. All welding shall be done by experienced welders qualified in accordance with the Standards of the American Welding Society. Welding electrodes shall comply with the requirements of ASTM Designation A-233. In all hand welding, the metal shall be deposited in successive layers and the minimum number of passes or beads in the completed weld shall be as follows: Steel Cylinder Thickness, Fillet Weld Inches Minimum Number of Passes Smaller than 3/16" 1 3/16" and 1/4" 2 5/16" 3 3/8" 3 Where welded joints are designated on the Plans, the pipe may be joined with rubber gaskets as specified in the above provision for rubber ring joints in lieu of slip (lap) joints. The outside recess between the bell Carlsbad MWD 080966 Steel Water Pipe and Fittings - 6 and spigot shall then be caulked with a rod to facilitate the welding. The weld shall be continuous for the full circumference of the pipe. After the joints have been welded, the joint shall be grouted with cement mortar in the same manner as specified for rubber ring joints. C-5. Butt strap closure joints shall be completed in the trench after the pipe has been laid to the alignment and grade shown on the Plans.

Carlsbad MWD 081066 Steel Water Pipe and Fittings (Pretensioned) - 4 CARLSBAD MUNICIPAL WATER DISTRICT STANDARD SPECIFICATIONS FOR TESTING AND STERILIZATION A. General; These Specifications designate the requirements for field test- ing and sterilization of all water mains and appurtenances intended for the conveyance of potable water under pressure. A-l. Scope of Work; The Contractor shall furnish all labor, materials (including water), tools, and equipment necessary to provide and complete field testing and sterilization as specified. B. Field Testing; B-l. After the pipe and all appurtenances have been laid and backfilled sufficiently for required restraint, they shall be subjected to a 4-hour hydrostatic pressure test. This test shall consist of subjecting the pipeline to a hydrostatic pressure of 50 psi in excess of the designated working pressure specified for the class of pipe at the low point in the section being tested. The pressure test shall be made subsequent to any trench backfill compactive effort with heavy duty compacting equipment having an overall weight in excess of 125 pounds. B-2. Maximum Length of Pipe to be included in any one test shall be not more than 2500 feet or the distance between valves, whichever is greater. B-3. Preparation; The line shall be filled with water at least 72 hours prior to testing. While filling and immediately prior to testing, all air shall be expelled from the pipeline. Where air valves or other suit- able outlets are not available for releasing air or applying the test, taps and fittings approved by the District's Representative shall be installed and later securely plugged. B-4. Procedure; The pressure in the pipeline shall be pumped up to the specified test pressure. When the test pressure has been reached, the pumping shall be discontinued until the pressure in the line has dropped 25 psi, at which time the pressure shall again be pumped up to the speci- fied test pressure. This procedure shall be repeated until 4 hours have elapsed from the time the specified test pressure was first applied. At the end of this period, the pressure shall be pumped up to the test pres- sure for the last time. B-5. Leakage shall be considered as the total amount of water pumped into the pipeline during the 4-hour period, including the amount required in reaching the test pressure for the final time. Leakage shall not exceed the rate of 4 gallons per inch of nominal inside diameter per 1000 feet of pipe per 24 hours. If leakage exceeds this rate, the weak points shall be located and stopped, and all defective pipe, fittings, valves and other accessories discovered shall be removed and replaced with sound material and the test shall be repeated until the leakage does not exceed the rate specified above. All perceptible leaks shall be similarly repaired. Carlsbad MWD 081066 Testing and Sterilization - 1 C. Sterilization; C-l. After pressure testing, the entire pipeline including all valves, fittings, hydrants, service laterals, and other accessories shall be sterilized in accordance with AWWA Specification C 601 which provides: Chlorine gas or chlorine compound solution shall be water mixed and introduced into the mains to form a chlorine concentration of approximately 25 ppm or that which will provide a minimum residual of 10 ppm in all parts of the line after 24 hours have elapsed. During the sterilization process all valves, hydrants and other accesso- ries shall be operated. After chlorination, the water shall be flushed from the line at-its extremities until the replacement water is equal chemically and bacteriologically to that of the permanent source of sup- ply. The Contractor shall keep chlorine residual testing and indicating apparatus available on the site during the entire sterilization period. D. Payment; D-l. Payment for field testing and sterilization of water mains and appurtenances and for conforming to all the provisions included herein shall be considered to be included in the contract unit or lump sum prices paid for the various items of work and no additional allowance will be made therefor.
