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: 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 olus 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 street subgrade or 4 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 reouired "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 coup- lings 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 will be paid for as extra work. Foundations in rock shall be constructed by removina 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 shallbe backfi11ed to proper grade and cross section with sand compacted to a minimum relative compaction of 90%. Carlsbad MWD Earthwork (Water Mains)-2 707 B-3. Backfil1; All trenches and excavations shall be backfi1 led 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, 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 contain 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. Carlsbad MWD Earthwork (Water Mains) - 3 707 Tamping Method: Backfill material shall be placed in uniform layers of the thickness specified above. The moisture content of the backfill material shall be near or at the optimum required for compaction and each layer shall be tamped until compacted to the required minimum 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 Sett!ing 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. 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 prevent 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 Carlsbad MWD Earthwork (Water Mains) - 4 707 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 approximately 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. 0 Carlsbad MWD Earthwork (Water Mains) - 5 707 CARLSBAD MUNICIPAL WATER DISTRICT STANDARD SPECIFICATIONS FOR PORTLAND CEMENT CONCRETE A.

Aggregates: All aggregates used in grout, mortar, and in concrete shall conform to the provisions of Section 90 of the Standard Specifications 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 admixture 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. Carlsbad MWD Portland Comdnt Concrete - 1 707 Only sufficient water shall be used in mixing any class of concrete to produce a workable mass suitable for the particular type of construction 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 minutes 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 continuously 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 manufacturer'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 4 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 arrangements, satisfactory to the District's Representative, with the supplier of the concrete, if transit mix concrete is being used, so that the District's Representative may be assured that once placement is started it can be completed without interruption. The vibrating equipment, including 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 fixtures, 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 Carlsbad MWD Portland Cement Concrete - 2 707 0 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 vibration and the vibrators are approved by the District's Representative. B-9. Forms: All forms shall be smooth, mortar-tight, true to the required lines and grades, and of sufficient strength to resist any appreciable 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 penetrating 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 expiration 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. Carlsbad MWD Portland Cement Concrete - 3 707 C 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 District's Representative. After the pour has been completed to the construction joint and the concrete 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. VWire 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. Except 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. When it is necessary to make a joint because of an emergency, reinforcing 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 back- filling 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: M148, Type II, White Pigmented. Application shall be done with hand spraying equipment in a manner satisfactory to the District's Representative. 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 finishing has been completed. The pigmented curing compound shall not be applied to the surfaces of'construction joints or on reinforcing steel. B-13. Surface Finishes: During the placing of concrete, care shall be taken in vibrating or otherwise consolidating the concrete to insure surfaces 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 Carlsbad MWD Portland Comont Concroto - 707 C 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 exercised 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 manner 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 discolorations. 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. 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 Designation A16. The various grades of steel may not be used inter- changeably 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 together to provide a minimum distance of 2 inches between the splice and the nearest adjacent bar or surface of the concrete.

Carlsbad MWD Portland Cement Concrete - 6 707 STANDARD SPECIFICATIONS FOR TESTING AND STERILIZATION A. General - These Specifications designate the requirements for field testing 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 sub- jected 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 excelled from the pipeline. Where air valves or other suitable 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 specified 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 pressure 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 Carlsbad MWD Testing and Sterilization - 1 707 O and the test shall be repeated until the leakage does not exceed the rate specified above. All perceptible leaks shall be similarly repaired. C. Sterilization C-l. After pressure testing, the entire pipeline including all valves fittings, hydrants, service laterials, 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 24hours have elapsed. During the sterilization process all valves, hydrants and other accessories 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 per- manent source of supply. The Contractor shall keep chlorine residual testing and indicating apparatus available on the site during the entire sterilization period. D. Payment - Payment for field testing and sterilization of water mains and appurtenances and for conforming to all the pro- visions 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.

Obstruction lights shall be on from sunset each day to sunrise of the next day, until such excavation is entirely refilled or such obstruc- tion is removed. Said barriers shall not be less than three (3) feet in height. On all projects involving excavations or obstructions which en- croach to within four (4) feet of the through traffic lane, a reflectorized "Road Construction 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 regul- ations adopted by the California Division of Highways pursuant to Section 21406 of the California Vehicle Code. Carlsbad MWD Soecial Provisions - 3 O Special Provisions Excavation Permit 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 pro- perly 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 inter- vals, unless he is specifically authorized in writing by the County Engineer Department Construction Engineer. If operations of the contractor do cause a public road to become impassable but for no longer than thirty (30) munite intervals and where a detour is not practical, he shall post and maintain at both ends of the work a 4' x 51 sign to read in large letters, "WARNING - CONSTRUC- TION WORK. TRAFFIC SUBJECT TO A 30-MINUTE DELAY". If traffic de- lays of more than thirty (30) minutes are anticipated, the contrac- tor shall provide a detour. All signs to be used on a County road shall be furnished and placed in conformance 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 Inter- ference 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. Detours If the construction work requires a detour, written permission shall be obtained from the Traffic Engineer of the County Engineer Department prior to establishment. The request for such a permit shall be made in writing and processed via the Construction Engineer.

Carlsbad MWD Soecial Provisions - 4707 O Special Provisions Excavation Permit 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 exca- vation 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 because of the local traffic volume or importance of the street. In ge- neral, 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 publicrin the opinion of the County Engineer. (1) 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 re- mainder of the area of trenching shall be available for safe vehicular and pedestrian traffic at all times. (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 remainder of the area of trenching operation shall be available for safe vehicular and pedestrian traffic at all times. (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. (4) Trench covered with temporary surfacing will be considered as open to traffic. Temporary surfacing shall conform to provisions of Paragraph 17 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 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 re- questing 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 requirements of the State of California "General Industry Safety Orders". Carlsbad MWD Soecial Provisions - 5 Special Provisions Excavation Permit 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 per- mittee 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 following modi- fications shall apply: M-1. 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 in diamet- er. This layer may contain stones, broken concrete, bituminous pavement or oil cake ranging in size up to six (6) inches maxi- mum diameter 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.6. 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 111 aggre- gate base furnished and placed in conformance with Section 26 of the Standard Specifications and the following modifications: Carlsbad MWD *M*i i n707 Special Provisions - 6 Special Provisions Excavation Permit Sand Equivalent 30 Minimum Resistance (R) Value 75 Minimumf 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 the event the R value of^the material is less than 70, it shall be removed from the project and replaced with suitable ma- terial . M-4i. 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 (51) 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, or A.S.T.M. Designation: D-1556 and Method "C" of A.S.T.M. Designation: D-1557. (Note 2 in Method C applicable only if the percentage of plus 3/4" material is greater than 10 percent by weight of the original sample.) Compaction tests will be taken throughout the project to determine whether the specified requirements have been met. The number of tests and their location and depth shall b.e left to the discre- tion 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 re- fill and recompact these to the densities required by these speci- fications 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. Carlsbad MWD Soecial Provisions - 7 707 Q Special Provisions Excavation Permit The permittee may backfill using any of the methods indicated below, if approved by the Engineer: M-4.1 Tamping Methods When machine tamping, hand tamping or hand-operated pneu- matic tamping 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 conformance 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 18, the Construction Engineer may authorize the option of jetting the complete trench depth and providing temporary co- ver, (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. 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 dele- terious matter, and shall be rammed with proper tools until thor- oughly compacted to.the density of the adjacent material. Carlsbad MWD Special Provisions - 8 707 Special Provisions Excavation Permit 0 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 dia- meter 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 b.e required, when approved by the Engi- neer. 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. P Special Circumstances On streets in commercial areas, urban type development, or having high traffic counts (5,000 cars per day or greater), the conve- nience 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 back- fill material. The backfill material shall be sand compacted by wetting or material 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 per- mit. Only emergency work will be allowed in commercial areas between the dates of Thanksgiving and New Year's Day. Q 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 Sur- facing" 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, of the Standard Specifica- tions. Carlsbad MWD Special Provisions - 9 707 Special Provisions Excavation Permit In the rainy season (October to May), when directed by the Con- struction Engineer, all trenches in paved traffic lanes shall be provided with temporary resurfacing, unless the permittee immedia- tely installs permanent resurfacing. Resurfacing R-l. 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 of 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 exist- ing 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 per- mittee's operations shall be replaced to a depth of at least six (6) inches with Class 111 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 replacement shall be as hereinafter specified.
