Rock shall be lard and durable, shall be well graded and shall range in size from one quarter inch (1/411) to two Inches (211). General: The price for all material necessary to be furnished by the Contractor for a complete Installation and construction of the work as shown on the plans, except for that material expressly specified herein as to be furnished by the City, shall be included in the 3- price bid for the relative items of work, and no other payment shall be made for such material. SECTION IV. CONSTRUCTION. Excavation: The excavation shall include the removal of all Parth and other ;material to such a depth as to provide a minimum cover of thirty inches (30 ") measur- ed between the top of the pipe and the surface of the street or right of way as that surface existed before excavation wes made. Bell -holes of sufficient size to give easy access to all sides of the joint shall be dug at each pipe or other joint. Trenches shall be of sufficient width to provide ample space for the proper laying of the pipe. The bottom of the trench shall be true and even to provide a uniform bearing along the full length of the pipe. All existing; pipes, conduits, sewers and /or other structures encountered during the excavation of the trench shall be carefully protected by the Contractor, and in the event of injury, they shall be restored by him, i,ithout additional compensation, to es good a condition as that in which they were found. Where existing driveways occur, the Contractor shall make provisions for trench crossings at these points by means of back -fills or temporary bridges, as directed by the ::ngineer. Laying of Pine: All pipe shall be laid in a straight line. The bottom of the trench shall be dug to a uniform grade with holes for the bells ?nd couplings, in order that the pine shall be laid on a firm foundation with a solid bearing the full len,th of the pipe. Before making; a joint the pipe shall be carefully bedded anc anchored by backfilling; between joints. EN Laying of Acbestos Cement Pipe: Asbestos Cement Pipe, instead of laying as hereinbefore provided, may be laid on wood blocks. For six inch (6 ") pipe and under two inch by four inch by ten inch (%" x 0 x 1011) shall be used and for eiLht inch (8 ") to twelve inch (1211) pipe both inclusive, two inch by six inch by twelve inch (2" x 6" x 1211) blocks shall be used. These wood blocks shall be placed directly under the fifth points of the pipe, which in the case of full length pipe are factory marked with the word "BLOCK ". After the aforesaid wood blocks have thus been placed, the pipe shall be backfilled between the blocks with selected material and thoroughly tamped to the horizontal diameter of the pipe. The pipe shall then be anchored in the same manner as that provided for other pipe. Whenever it is necessary to cut asbestos cement pipe, it shall be done with a cr-rpenter's five (5) or six (6) point rip saw or a two -.man crosscut saw and shall be done in such a manner ?s to make a clean and even cut. Placing; of Fitting: All fittings shall be accurately located as shown on the plans or as directed by the Ene,lneer. Concrete thrust blocks, as hereinafter specified, shell be placed behind fittings when shown on the plans or when directed by the Engineer. Joints: Unless otherwise shown on the plans, all Joints of cast iron pipe and fittings shall be cement Joints. Joints lead Joints. Joints and /or fittings Joints with the simplex at gate velves and fire hydrants shall be of asbestos cement pipe with cast iron pipe shall be lead Joints. between asbestos cement pipe shall be made couplings consisting of one (1) asbestos 5— cement sleeve and two (2) rubber rings furnished by the T anufacturer. All Joints shall be tight under test pressure as herein- after specified. Cement Joints: The cement used in cement joints shall be as hereinbefore specified and shall be free from all lumps. The joint shall be made in the following manner. A string of jute shall be calked into place with a calking tool. The joint shall then be filled with neat cement, which has been moistened so that when thoroughly mixed by hand, it will be of such a consistency, that when gripped tight, it will hold the form of the hand, and when dropoed twelve inches (12 ") it will crumble. The cement shall be calked into place with heavy blows until the cement is thoroughly packed in the back of the socked. The process shall be continued until the bell is packed solid out to the face. Care shall be taken to keep the cement used in making joints free from dirt and lumps no matter how small. Cement shall be mixed only in sufficient quentities for one joint and for immediate use. Immediately upon completion of the calking, the joint shall be wiped with neat cement in such a manner as to make a smooth and even bead around the joint and shall then be covered with sufficient earth to protect it from the air and sun. The joint shall then be wet and kept moist for a period of seven (7) days. Pipe shall not be jointed within two hundred feet (2001) of the point of lowering and placing of the pipe. No water shall be allowed in the line within forty -eiLht (49) hours of the making of the last cement joint. 0 All leaks appearing under test pressure, ss hereinafter specified, shall be stopped by chipping out the joint and refilling with lead calked into place as hereinafter specified under lead joints. Lead Joint: Lead Joints shall be made in the following manner. A double string of oakum, long enough to allow a good lap, shall first be calked into place with a calking or yarning iron, leaving a t *ao inch (211) space for the lead. Lead shall be run in at that certain temperature, which brings an irridescent bluish tinge to the surface of the metal. Lead joints shall be calked off and finished with a narrow Iron in a neat and workmanlike manner. Simplex CouplinFC Joints: Simplex couplinL joints shall be made in the follorring,manner. After a length of asbestos cement pipe hAs been placed in the trench as hereinbefore specified, the simplex coupling shall be placed thereon. After the inside of the sleeve has been thorougrly exam- ined for cleanliness and smoothness, the end thereof with the high shoulder or the back end first shall be slid on the pipe to the rear of the machined portion thereof. One rubber ring shall then be placed on the pipe and shall be rolled back and forth on the pipe un2.il all twists have been straightened out. It shall then be rolled back on the pipe a distance equal to the length of the sleeve. It is important, that this distance be the same all the way around the pipe; therefort- a guage shall be used to check this distance. The second rubber ring shall then be placed upon the pipe In the same manner as the first and as close to the end of the pipe as possible. Thereafter the next length of pipe shall be lined up to a butt joint, the machined surfaces of the pipes bainE made 7 flush at the bottom. The lateral and /or vertical dis- plecement between pipes shall not exceed one eighth inch (1 /$ 11) and the space between pipe ends shall not be greater than one quarter inch (1/411). Hydraulic or friction type coupling pullers, approved by the Engineer, shall be used for assemblinS the simplex couplings. Before the coupling is pulled into place, the final location of the coupling shall be marled on the pipe. This dimension shall be equal to one half (1/2) the length of the sleeve measured from the end of the uioe. After the coupling has thus been bulled to the aforesaid location, the final locations of both rubbe- rings shall be checked with a gauge the entire circumference of the pipe. After the assemb ly of the covplin„ has thus been com- plated, the unjointed end of the pipe shall be raised ten Inches (109 and then be lowered once in order to separate the ends of the nine within the couplin,, to make provision for expansion and contraction. Placing of Gate Valves and Fire Hydrants: The location of all gate valves and fire hydrants shall be approved in the field by the Engineer before the same are calked. Valves: Valves shall be set plumb. Joints at valves shall be lecd joints as hereinbefore sppecifled. The Contractor shell not be recuired to install valve boxes and covers. This work will be done by the City. Fire Hydrants: Fire hydrants shall be set plumb with the top of the bury leval vith sidewalk o ade. Fire h;;dran`s shall be blocked in back against undis- turbed earth with a concrete block a hereinafter specified. The Joint at the fire hydrant bury vith the hydrant lead and the joint at the hydrant lead *with the main line fitting; or other joints in the hydrant 1--j, if any, shall lei . joints. L3 The price bid for setting the hydrant shall include the connection with the main, the installation of the lead together with the installation of the bate valve, If shown on the plans, the placing of the concrete block, hereinbefore referred to, and all other work necessary and appurtenant to a complete installation of the fire hydrant. Whenever the removal and reinstallation of a fire hydrant is required on the plans, the price bid for such removal and reinstallation shall include all wort: necessary to remove the fire hydrant, gate valve, if any, and hydrant lead, place a cast iron plu6 in the main line fittin;, making a lead joint, and to reinstall the fire hydrant complete as hereinbefore provided for settinr, of fire hydrants. Sterilization and Tests: Careful inspection shall be made during, the progress of the installation in order to eliminate tho possibility of any forelLn matter vetting into the pipe. .:s eech joint is laid, HTH shall be placed therein In such a quantity, which will provide not less than ten (10) parts per million (1,00,000) of free chlorine, when the pipe is filled with water, as hereinafter provided. Before the trench is backfilled, the entire installation to be tested shall be filled with water under no pressure for the purpose of dissolving; said HTH and thereby steriliz- ing the installation and for the further purpose of curing; the cement joints, if any. In the case of cement joints the water shall remain in the pipe for a period of seven (7) days, in the case of other than cement joints it shall remain for forty -eight (46) hours before the pressure is applied. 9- The entire installation shall satisfactorily with- stand a hydrostatic test at one hundred (100) pounds per square inch pressure for a period of one (1) hour without showing any leak. Backfillinp: Immediately of completion of the above test, unless otherwise directed by the Engineer, all trenebas and excavations shall be beckfilled. The beckfillin6 shall include the refilling and the consolidation of the fill in trenches and eNe vations uo to the subgrede of the street or alley improvements or to the original sur- face of the ground as the same existed before the excavation was :Wade. Where the excavations do not supply sufficient :material for making the fill, the Contractor shall supply the deficiency. No extra compensation shall be made for the supplying of such deficiency. BacIfillino shall be done with Zood sound earth, sand or ,ravel, and no oil cake, macadam, bituminous pavement, concrete, lock or other lumpy material shall be used in making backfill, unless the lumps are well scattered, do not exceed four inches (4") in diameter, and are not placed within one foot (11) of the surface. No material of a spongy, perishable or otherwise improper nature shall be used in backfilling. All sheet, piping and other timber and debris shall be removed from the excavation. The backfill shall be made to six inches (5") below street or alley -grade or below the original surface d7the ground by usinb shovels, scrapers, buckets or any other means the Contractor may elect. Unless "Special 3ackfillin6" is required and so Indicated on the plans, the backfill shall be therouthly consolidated by floodinZ. DurinL flnodin^ bore shall be used continuously in the manner directed by theLnoineer, in_ to facilitate the entry of the water into ell part-. of the backfill. The backfill shall then be completed to the limits hereinbefore specified. SPECIAL Special Backfillin ;'hen 'Special 3clfi111ng' is required and so indicated on the plans, the 'Special Provisions' any /or plans *,ill ,provide specifications for such beckfillin,•. Resurfacing of Streets and Alleys: The re=urfacin,, of streets and alleys will be done by the City." SECTION 2.
