BEWO 5527 A-B Painting - 2 STANDARD SPECIFICATIONS FOR PORTLAND CEMENT CONCRETE A. General: The contractor shall furnish all labor, materials, tools and equipment for the construction of plain and reinforced concrete as shown on the plans and herein specified. B. Materials and Workmanship: B-l. Cement: Cement shall be Portland cement Type II. B-2. Aggregate: All aggregates used in grout, mortar, and in concrete shall conform to the provisions of Section 26 of the Standard Specifi- cations of the California Division of Highways dated August, 195^- The maximum nominal size of coarse aggregate shall be one and one-half inch (1-1/2"). B-3- Water: The water used shall be of potable quality. B-U. Admixtures: Admixtures to prevent segregation and to improve work- ability or to accelerate the setting of the concrete will be per- mitted provided the admixture proposed shall first be approved in writing by the Engineer and the proportions of the admixture to be used shall be fixed by Engineer. B-5- Strength Requirements: All concrete shall be proportioned to attain a minimum cylinder strength of 3>000 psi in twenty-eight (28) days. The compressive strengths are to be determined in accordance with ASTM C39- Not less than six 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 Engineer. The contractor shall notify the Engineer of his proposed source of aggregate in sufficient advance time to permit the design of the mix. 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 homog- eneous 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 Engineer can conveniently observe the consistency and uni- formity of the concrete in the mixer during the operation. Portland Cement Concrete Standards - 1 Only sufficient water shall be used in mixing any class of concrete to produce a workable mass suitable for the particular type of con- struction 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 ninety (90) seconds for a stationary mixer smaller than two (2) cubic yards in capacity and for not less than two (2) minutes for a larger stationary mixer. If transit mix concrete is used, the mixing time shall not be less than three (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 sixty (60) minutes for concrete mixed in transit mixers. B-8. Placing: Concrete shall be placed only in the presence of a duly authorized representative of the Engineer and not until all form work, reinforcement, installation of fixtures to be embedded, and preparation of concrete surfaces to be bonded to have been approved by him. All concrete placed in violation of this provision will be rejected. 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 by wire brushing, sand blasting or air and water pressure jet. 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 six feet (6') 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 stand-by concrete mixing equipment ready for use in case of breakdown or he shall make arrange- ments, satisfactory to the Engineer, with the supplier of concrete, if transit mix concrete is being used, so that the Engineer may be assured that once placement is started it can be completed without interruption. The vibrating equipment, including stand-by equipment, shall be at the site and tested in the presence of the Engineer'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 Portland Cement Concrete Standards - 2 in use shall be ample to consolidate the incoming concrete to a proper degree within fifteen (15) minutes after it is deposited in the forms. In all cases, at least two (2) vibrators shall be available at the site. The use of approved 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. 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 con- crete, 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 forty-eight (U8) 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 ply- wood. 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 one inch by one inch (l" x l") triangular filets. Form clamps and ties with effective water stops shall be used to main- tain 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 one and one-half inches (1-1/2") 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 and stripping of forms will not alter their alignment or location. Openings may be formed at sleeve locations and sleeves placed and grouted with cement mortar containing fifteen (15) pounds of EMBECO, or equal, per bag of cement, after wall concrete is placed. Portland Cement Concrete Standards - 3 B-ll. Joints: Construction joints shall be made only where shown on the plans unless otherwise approved by the Engineer. In case of emergency, construction joints shall be placed as directed by the Engineer. Construction joints shall be mechanically bonded by means of keys cast into the joint surfaces. B-12. Curing: All newly placed concrete shall be kept wet by the con- tinuous application of water for the first seven (7) days after the concrete has been placed. The use of curing compounds will not be per- mitted. B-13- Surface Finishes: During the placing of concrete, care shall be taken in vibrating or otherwise consolidating the concrete to in- sure 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 one and one-half inches (1-1/2") 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 one part by volume of cement to two parts of sand. The mortar shall contain fifteen (15) pounds of EMBECO, or equal, per bag of cement used. Care shall be exercised to obtain a perfect 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 immed- iately following the removal of forms. If in the judgment of the Engineer 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 un- acceptable and require the removal and replacement of that portion of the structure. Except for surfaces which are to be buried, all fins and other pro- jections 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. Portland Cement Concrete Standards - k B-lU. Reinforcement: Reinforcing bars shall conform to the requirements of the Standard Specifications for Minimum Requirements for the De- formations of Deformed Steel Bars for Concrete Reinforcement, ASTM Designation A 305 and of the Standard Specifications for Billet Steel Bars for Concrete Reinforcement, ASTM Designation A15; or Standard Specifications for Rail-Steel Bars for Concrete Reinforcement, ASTM Designation Al6; or Standard Specifications for Axle-Steel Bars for Concrete Reinforcement, ASTM Designation Al85- Bends for stirrups and ties shall be made around a pin having a dia- meter not less than three (3) times the minimum thickness of the bar. Bends for other bars shall be made around a pin having a diameter not less than six (6) times the minimum thickness of the bar, except that for bars larger than one inch (l") the pin shall be not less than eight (8) times the minimum thickness of the bar. All bars shall be bent cold. Metal reinforcement shall be accurately placed in accordance with the plans and shall be securely held in position by wiring at inter- sections with No. l6 or larger wire and by using concrete spacers. Reinforcement, at the time concrete is placed, shall be free from rust, scale or other coatings that will destroy or reduce the bond. Metal supports may be used provided no portion of the support ex- tends to within one and one-half inch (1-1/2) of the surface of the concrete. Wooden supports shall not be used.

All cement mortar shall develop an ultimate compressive strength of 3,000 to 4,000 psi at 28 days when tested in accord- ance with ASTM Specification C-39 or the latest re- vision thereof. B-5.3. Application and Treatment: The mortar shall be applied to the interior surface of the pipe by means of equip- ment specifically designed for the purpose, using a trough or troughs or a retracting feed line or lines in such a manner that uniform distribution throughout the length of pipe is attained. The pipe shall be slowly rotated with its axis in a horizontal position while the mortar is being introduced to assist in uniformity of distribution. Both ends shall be provided with suitable end dams during the spinning operation. These dams shall assist in controlling the thickness of the mortar coating being applied and shall provide a square-finished end for the lining. After application of the mortar, the rate of rotation of the pipe shall be uniformly Increased to a speed that will compact the mortar. This speed shall be maintained until all excess water has been forced to the surface. During the spinning operation surplus water shall be expelled from the pipe by means of a blower or other suitable means. The peri- pheral speed and the length of spinning time shall be sufficient to obtain a dense, well-compacted lining with a smooth surface free from all defects. The thickness of the lining shall be as shown in the following table: BEWO 552? A-B Steel Pipe Standards - 5 Nominal Diameter Lining Thickness 6~" through 12* 5/T5"n 14" and 16" 1/2 " 18"through 24" 3A " Immediately after completion of the above operation, the lining shall be water cured without being disturbed for at least seven (7) days in a manner that will prevent loss of moisture. This curing time may be reduced to a minimum of four (4) days if an exterior cement mortar coating is to be applied to the pipe. B-6. Exterior Coating: steel pipe lines shall receive an exterior cement mortar coating. B-6.1. Materials: Materials for the exterior cement mortar coating shall be the same as those used for the interior cement mortar lining as spec- ified in Paragraph B-5.2. above. B-6.2. Application and Treatment: After the interior of the pipe has been lined, a cement mortar coating shall be applied to the outside of each section of pipe by means of a nozzle or nozzles, through which the mortar is forcibly expelled against the outside surface of the pipe in such a manner as to form an even, dense and tightly adhering coating. During the coating operation, the pipe shall be rotated and moved in a longitudinal direction beneath the nozzles. The rotation and longitudinal travel of the pipe shall be uniform and at the proper rate to provide a coating having a minimum thickness of 3A inch. The standard reinforcing for the cement mortar coating shall be spirally wound steel reinforcing wire at a pitch of one inch (l") embedded in the center of the coating. The wire shall be a bright basic wire with an approximate ultimate tensile strength of 80,000 psi and shall be No. l6 gauge or heavier. Immediately after the coating has been completed, the outside of each end of each section shall be cleansed to bare metal and shall have the mortar trowelled and shaped to suit the type of joint being used. All bare metal exposed at the ends of each section of pipe shall be cleaned and protected against corrosion. Each day's production of cement mortar lined and coated pipe shall be plainly identified by indelible markings inside of one (1) of each joint. The coating shall then be water cured for at least seven (7) days without being disturbed. B~7- Fabricated Fittings; All bends, ells, tees, crosses, reducers and other special fittings shall be constructed of cement mortar lined steel pipe with cement mortar coating as specified for pipe mains and shall be fabricated at the plant for delivery and installation in the work in accordance with the Tentative Standard Specifications for Dimensions for teel Water Pipe Fittings, AWWA C-208-55T.

BEWO 5527 A-B Steel Pipe Standards - 6 B-7-2. Butt Closure Joints: Butt closure joints shall conform to the details shown on the Plans and shall be installed at all points where a butt closure is made. The butt straps shall be of the same thickness as the pipe wall, at least ten inches (10") wide, and rolled to fit the outside diameter, and shall be centered over the ends of the pipe sections they are to join. They shall be field welded to the outside of the pipe along both edges by full circumferential fillet welds or one of the edges may be shop welded and other field welded. A half of a standard five inch (5") pipe coupling shall be shop welded to the top section of the butt strap to permit access for mortaring the inside of the joint. After welding and mortaring, this coupling shall be closed with a standard cast iron plug. In addition, the joint shall be coated with the same material used to coat the pipes. B-8. Inspection: The District's Representative shall at all times have the right to inspect the work and materials in the course of manu- facture. The manufacturer shall furnish the District reasonable facility for obtaining such information as it may desire regarding the progress and manner of the work and the character and quality of materials used. B-9- Shop Plans: Shop drawings of all pipe and fittings shall be sub- mitted to the District's Engineer and shall be approved by him prior to fabrication of the pipe and fittings. Such approval is an additional precaution against errors and is not to be construed as relieving the Contractor of the full responsibility for the accuracy of the shop plans. B-10. Loading and Transporting Pipe: During loading and unloading operation the pipe shall be handled with slings of sufficient width to prevent damage to the exterior coating and in such a manner to prevent injury to the cement mortar lining. Pipe loaded for trans- porting to the job site shall be supported and chocked with sawdust bags or by other means which will properly support the pipe and prevent its being damaged while in transit. Unloading shall be accomplished in a workmanlike manner and every precaution shall be taken to prevent damage to the pipe. Under no circumstances are pipe sections to be dropped or bumped in handling. C. Installation: C-l. Excavation and Backfill: Excavation and backfill shall conform to the Standard Specifications for Earthwork. C-2.

The trench shall have a flat or semicircular bottom conforming to the grade to which the pipe is to be laid. Pipe shall not be laid on earth mounds. C-2.1. Welded Joints: Joints shall be welded after the pipe has been laid in the trench to the grade and elevation shown on the plans. 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 re- moved 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 squeegie through the pipe. For pipe 2V in diameter and larger, the inside of the joint shall be hand painted. 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 require- ments of ASTM Designation A-233. In all hand welding, the metal shall be deposited in suc- cessive layers and the minimum number of passes or beads in the completed weld shall be as follows: Steel Cylinder Thickness, Inches 3/l6" or smaller 1/V 5/16" 3/8" Fillet Weld Minimum Number of Passes 1 2 3 3 After the joints have been welded and inspected, a cement mortar coating shall be applied over the joint and lapped and bonded with the existing coating on the pipe in such a manner as to insure continuous uniform protection over the entire pipeline. Each joint shall be shaded with moistened backfill material or at the option of the Contrac- tor coated with an impervious membrane (Hunt's Prucess or approved equal) immediately following the application of the cement mortar coating. BEWO 5527 A-B Steel Pipe Standards - 8 C-2.2. Rubber Ring Joints: When the pipe is being laid, the ends of the pipe shall he thoroughly cleaned and the gas- ket placed in the groove on the spigot ring and the spigot end of the pipe shall then be entered into the bell of the adjoining pipe and forced into position. The gasket and the inside surface of the bell shall be lubricated with a suitable vegetable soap compound which will facilitate the telescoping of 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 squeegie through the pipe. The outside joint recess shall then be poured with grout after a felt sheet or other suitable material has first been placed around the pipes at the joints and held securely in place to prevent leakage while the joint is being poured. The grout shall consist of one part cement to one-and-one-half parts sand and be mixed to the consistency of thick cream. The joints shall be poured and rodded from one side only until the grout shows on the other side. Care shall be exercised to fill the joint completely. Approximately two hours sub- sequent to the pouring of the joint, the joint shall be re- checked and if any settlement, leakage, or shrinkage has taken place, the joint shall be refilled with grout. C-2.3- Flanged Joints: Flange faces and gaskets shall be thoroughly cleaned just prior to jointing. Following tightening of the bolts, all exposed metal surfaces shall be cleaned, primed, and coated with two coats of hot asphalt. Primer shall be Union Bituminous Primer or approved equal, and asphalt shall be Union Pipe Dip or approved equal. The primer shall be allowed to dry one-half to two hours prior to applying the first hot sling coat of asphalt. The second hot sling coat shall not be applied until the first has been allowed to cool. Care shall be taken to insure that all exposed metal surfaces are coated. C-2.4. Dresser-Type Coupling Joints: Just prior to installation, each pipe end for a distance of 6 to 8 inches back from the end shall be thoroughly cleaned to remove oil, dirt, loose scale, rust and other foreign matter. Flanges, gaskets, sleeves shall then be assembled on the pipe ends in accor- dance with the manufacturer's recommendations. Gaskets, pipe ends and coupling sleeve flares shall be lubricated with a vegetable soap compound to facilitate the joining. BEWO 5527 A-B Steel Pipe Standards - 9 Coupling sleeves shall "be accurately centered over the pipe ends and one pipe end shall touch the other or pipe ends shall touch the coupling sleeve centering stop if the coupling sleeve is so equipped. Bolts shall be tightened to the torque recommended by the manufacturer and the Gbntractor shall provide and keep at the site a torque wrench for checking the torque on the bolts. Prior to applying the asphalt coating specified below, the torque on all bolts shall be checked in the presence of the District's Representative and, where necessary, shall be ad- justed so that all bolts are at recommended torque. All exposed coupling and pipe surfaces shall be primed and asphalt coated as specified for flanged joints in Paragraph C-2.3 above. "Buttering" with cement mortar and swabbing or painting of the inside of the joints is not required. 0-3. Concrete Thrust Blocks: Concrete thrust blocks shall be placed as shown on the Plans and shall consist of Class B portland cement concrete containing not less than five (5) sacks of portland cement per cubic yard and shall conform to the applicable provisions of Sections 26 and 27 of the State of California, Department of Public Works, Division of Highways Standard Specifications dated August, Concrete blocks shall be placed between the undisturbed ground and the fitting to be anchored. Quantity of concrete and the area of bearing on the pipe and undisturbed soil shall be as shown on the Plans or directed by the District's Representative. The concrete shall be so placed, unless specifically shown otherwise on the Plans so that the pipe joints and fittings will be accessible for repairs. C-k. Preventing Foreign Matter from Entering the Pipes: At times when the pipe laying is not in progress, the open ends of the pipe shall be closed by a wooden plug or by other means approved by the District's Representative. This provision shall apply during the noon hour as well as overnight. (-'~5- Testing: After the pipe has been laid, the pipeline and appur- tenances shall be subjected to a hydrostatic pressure test of fifty pounds per square inch (50 Ibs. psi) in excess of the desig- nated working pressure for the class of pipe being tested. The maximum length of pipeline which may be tested at one time shall be 2500 feet except for those portions of the pipeline where the distance between valves is greater than 2500 feet. BEWO 5527 A-B Steel Pipe Standards - 10 Duration of pressure test shall be four (4) hours and the test shall be conducted in the following manner: All air shall be expelled from the pipe. To accomplish this, if air valves or hydrants or other outlets are not available, taps shall be made at the high points in the pipeline to expel the air and these taps shall be tightly plugged afterwards. The pressure in the pipeline shall then 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 four (4) hours have elapsed from the time the specified test pressure was first applied. At the end of the four (4) hour period the pressure shall be pumped up to the test pressure for the last time. The leakage shall be considered as the total amount of water pumped into the pipeline during the four (4) hour period including the amount required in reaching the test pressure for the final time. Leakage shall not exceed the rate of twenty (20) gallons per inch of diameter per mile of pipe per twenty-four (2k) hours. Any noticeable leak shall be stopped and all defective pipe, fittings, valves and other accessories discovered in consequence of the test shall be removed and replaced by the Contractor with sound material and the test shall be repeated until the total leakage during a test of four (4) hours duration does not exceed the rate specified above. All concrete anchor blocks shall be allowed to cure for at least five (5) days' prior to testing and all mortared joints shall be allowed to cure for not less than three (3) days prior to testing. C-6. Sterilization: Subsequent to the pressure tests and prior to acceptance of the work, the entire pipeline including all valves, fittings and other accessories shall be sterilized in accordance with American Water Works Association "Standard Procedure for Dis- infecting Water Mains," AWWA C-601-54. Treated water shall be retained in the pipes for at least twenty- four (24) hours and a residue at not less than ten (lO) ppm shall be produced in all parts of the line after the twenty-four (24) hour period has elapsed. During the sterilization process all valves and other accessories shall be operated. After chlorination, the water shall be flushed from the line at its extremities until the replacement water tests are equal chemically and bacteriologically to those of the per- manent source of supply. BEWO 5527 A-B Steel Pipe Standards - 11 D. Measurement and Payment: D-l. Measurement: Measurement for payment for steel pipe water main and fittings will be made along the centerline of the pipe from pipe end to valve flange or to centerline of intersecting pipe, as the case may be, as actually constructed, complete in place, and in accordance with the Plans and these Specifications. D-2. Payment: The price paid per linear foot for steel pipe water main shall include full compensation for furnishing all labor, materials, tools and equipment and doing all the work involved in furnishing and installing steel pipe water main and fittings complete in place as herein specified.

BEWO 5527 A-B Water System Earthwork Standards - 1 B. Materials and Workmanship B-l. Trench Excavation and Backfill B-l.l. Trench Excavation: Excavation for pipelines, fittings, valves, and appurtenances shall be open trench to the depth and in the direc- tion necessary for the proper installation of the same as shown on the plans. B-l. 11. Trench Width: The minimum width of unsheeted trenches shall conform to the following tabulation: Nominal Inside Pipe Diameter Trench Width 4" through 12" Outside Diameter plus 12" 14" through 24" Outside diameter plus 16" B-l.12. Correction of Faulty Grades: Should the excavation for the pipe line be carried below grade without instructions from the District's Representative, it shall be refilled to proper grade with sand, gravel or loose earth free from stones, clods, etc., which shall be furnished and tamped firm and unyielding at the expense of the Contractor. B-l.13. Foundation in Good Soil: The trench shall have a flat or semicircular bottom conforming to the grade to which the pipe is to be laid. The bottom of the trench for steel pipe and con- crete cylinder pipe shall be graded and prepared to provide a firm and uniform bearing throughout the entire length of each joint of pipe. Steel pipe and concrete cylinder pipe SHALL NOT be laid on earth mounds. Asbestos-cement pipe shall be laid on earth mounds located at one-fifth (1/5) of the pipe length from each end. B-l.14. Foundations in Poor Soil: All soft, spongy or unstable material in the bottom of the trench shall be removed to a depth as determined in the field by the District's Representative. Payment for the removal of material to a depth of two feet (21) below the bottom of pipe grade shall be considered to be included in the contract prices paid for the various items of work and no additional allowance will be made therefor. The removal of material from depths greater than two feet (21) below the bottom of pipe grade will be paid for as extra work. B-l.15. Foundations in Rock: Where rock is encountered, it shall be removed below grade and the trench backfilled with sand, gravel, or loose earth free from stones, clods, etc., which shall be tamped or otherwise compacted to provide a cushion with a thick- ness under the pipe of not less than one-half inch (1/2") per inch of nominal diameter of pipe to be installed with a minimum allowable thickness of six inches (6"). BEWO 5527 A-B Water System Earthwork Standards - 2 B-1.16. Shoring, Sheeting and Bracing of Trenches: Whenever it is necessary to prevent caving, trenches shall be adequately sheeted and braced. Where sheeting and bracing are used, trench widths shall be increased accordingly. Sheeting shall remain in place until the pipe has been placed, tested for defects and repaired if necessary, and the backfill in the "pipe zone" has been completed. B-1.2. Trench Backfill: All trenches shall be backfilled after pipe, fit- tings, valves and appurtenances have been installed. B-1.21. Procedure at Pipe Zone: Selected backfill material consisting of sand or loose earth free from stones, clods or other deleterious material shall be placed in the trench simultaneously on each side of the pipe for the full width of the trench in layers of about six inch (6") in depth. Each layer shall be thoroughly compacted by tamping or, where the material is sufficiently granular in nature as deter- mined by the District's Representative, by water settling. Particu- lar 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 cover- ing. The pipe zone shall be considered to extend six inches (6") above the top of steel pipe and concrete cylinder pipe and twelve inches (12") above the top of asbestos cement pipe. B-1..22. Procedure Above Pipe Zone: From the top of the selected back- fill to ground surface, the material for backfill may contain stones ranging in size up to eight inches (8") in diameter, in quantity not exceeding forty per cent (40%) of the volume when said coarse materials are well distributed throughout the finer material and the specified compaction can be attained. B-1.23. Compaction: Except as otherwise noted on the plans or in the Detail Specifications, all backfill above the "pipe zone" shall be thor- oughly compacted to a relative minimum density of ninety per cent (90%) by tamping or water settling. The contractor's attention is directed to paragraph A-2, Earthwork in County and State Rights of Way. B-1.231. Tamping Method: When the tamping method is used, proper- ly moistened fill material in uniform layers shall be tamped until compacted to the required relative minimum density. At the time of compaction, the moisture content of the backfill material shall be the optimum or such that the required compaction will be ob- tained. Heavy duty compacting equipment having an over-all weight in excess of 125 pounds shall not be used until backfill has been completed to a depth of two feet (21) over top of pipe. BEWO 552? A-B Water System Earthwork Standards - 3 B-1.232. Water Settling Method: When the water settling method is used, the trench shall be backfilled in uniform layers not exceeding eighteen inches (18") in thickness. Each layer shall be diked across at suitable intervals and the trench between the dikes shall be kept filled with water during and after de- posit of backfill material until sufficient time has elapsed for the layer to become saturated. This method shall not be used when in the opinion of the District's Representative the backfill material is not sufficiently granular in nature to consolidate properly by such methods. B-1.3. 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 such surplus material does not Contain any rocks or lumps which cannot be readily covered by spreading. B-1.4. Imported Backfill Material: Whenever the excavated material is not suitable for backfill, the Contractor shall arrange for and furnish suitable imported backfill material at his expense. He shall dispose of the excess trench excavation as specified in the preceding para- graph. The backfilling shall be done in accordance with the methods described above. B-1.5. Final Clean-Up: After backfill has been completed, the right of way shall be dressed smooth and left in a neat and presentable con- dition. On slopes where in the opinion of the District's Representa- tive rainfall runoff would create an erosion problem, the Contractor shall excavate at approximately two hundred foot (2001) intervals V-type interception ditches to collect and carry runoff to the low side of the right of way. The interception ditches shall be approxi- mately one foot (I1) deep and shall be skewed approximately forty-five degrees (45°) with the centerline of the right of way. B-2. Structure Excavation and Backfill: B-2.1. Structure Excavation: Structure excavation shall include the removal of all material of whatever nature necessary for the construc- tion of structures and foundations in accordance with the plans and specifications. It shall include the furnishing of all labor, mater- ials, tools, and equipment and doing all the work in the installation and subsequent removal of all shoring, sheeting, bracing, and other details which may be necessary. B-2.2. Structure Backfill: After structures and foundations are in place, backfill shall be placed to the original ground line or to the limits designated on the plans. No material shall be deposited against the walls of concrete structures for a period of fourteen (14) days following pouring of the concrete. BEWO 552? A-B Water System Earthwork Standards - 4 B-2.21. Compaction: Backfill shall be placed in horizontal layers not exceeding six inches (6") in depth and shall be moistened and thoroughly tamped, rolled or otherwise compacted to a minimum relative density of ninety per cent (90%). Water settling will not be permitted. B-2.22. Material: Backfill material shall consist of sand or loose earth, free from stones, clods or other deleterious material. When material from the excavation is unsuitable for use in backfill, it shall be disposed of as specified in Para- graph B-1.3 above and suitable material shall be arranged for and furnished by the Contractor at his expense. B-2.3 Surplus Excavated Material: Surplus material from the Excava- tion remaining after backfilling shall be disposed of as specified in Paragraph B-1.3 above. B-3. Excavation and Embankment for Roads. Reservoir Sites. Chlorination Sites. Pumping Station Sites, and Other Structure Sites: B-3.1, Excavation: Excavation shall include the performance of all necessary operations to clear the right of way or site and to ex- cavate all materials of whatever nature necessary for the construction of reservoir sites, chlorination station sites, pumping station sites, structure sites, parking areas, ditches and roadways to the line and grades shown on the plans or required by these speci- fications. B-3.11. Rock Excavation: In solid rock excavation or other material which cannot be readily plowed, the material shall be loosened and broken up so that any ribs or solid projections will be at least six inches (6") below finished grade. B-3.12. Water Channels: Water channels and ditches shall be excavated at the locations shown on the plans and/or as staked in the field. B-3.2. Embankment: It is the intent of the plans and specifications that all excavated material be placed in embankments or disposal areas designated on the plans. Finished contours and grades shown on the plans are subject to modification in the field by the District's Representative if necessary to accomplish this balance between excavation and embankment. B-3.21. Original Ground Preparation: Areas over which embankments are to be constructed shall first be cleared of all deleterious materials, plowed, scarified or otherwise broken up to allow new fill material to unite with the old earth. B-3.22. Compaction: Except as otherwise noted on the plans or in the Detail Specifications all embankment shall be carried up in layers not exceeding eight inches (8") in thickness and shall be compacted to a minimum relative density of ninety per cent (90%). BEWG 5527 A-B Water System Earthwork Standards - 5 B-3.3 Slopes: Excavations and embankments shall be finished with all slopes in conformity with the lines and grades shown on the plans and/or staked in the field. Fill slopes shall be compacted by means of sheepfoot rollers or other suitable equipment approved by the District's Representative. Slope compacting operations shall be continued until the slopes are stable and there is no appreciable amount of loose soil on the slopes. B-3.4 Finish Grade: After the roadbed or site has been constructed to the line and grade as herein specified, the entire area shall be watered, shaped, and rolled to provide a finish surface or sub-grade for base materials that is true to grade and cross-section and free from bumps and irregularities. C, Payment: Payment for earthwork and for conforming to all of the provisions of these Specifications 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.
