Common use of PIPE INSTALLATION Clause in Contracts

PIPE INSTALLATION. A. General: Unload pipe, fittings and accessories near the place where they are to be laid in the trench, and handle with care to avoid damage. Cutting of pipe shall be done by means of an approved type of mechanical cutter. B. Placement of Pipe: 1. Clean and inspect all sections of pipe, fittings and accessories for damage immediately prior to placement in the trench. Reject all defective materials, and remove them from the project. Place pipe, fittings and accessories in the trench, and position them utilizing hoisting equipment. Lay pipe true to line and grade, with uniform bearing under the full length of the pipe barrel. 2. Connect pipe joints and fittings in accordance with the pipe manufacturers' recommendations. Gaskets and lubricants shall be the type recommended by the pipe manufacturer. Insert the spigot end of the pipe into the bell to the required depth and in such manner as to avoid displacement of the gasket. Jointing of mechanical-joint pipe shall be accomplished such that the gland is positioned evenly by tightening alternately the bolts spaced 180 degrees apart. 3. At times when pipe laying is not in progress, close the open ends of the pipe with a watertight plug. This provision shall apply during the lunch period, overnight, or any other time when work is not in progress. 4. No pipe shall be laid in wet trench conditions that preclude proper bedding, or on a frozen trench bottom, or when in the opinion of the Engineer, the trench conditions or the weather are unsuitable for proper installation. C. Concrete Thrust Blocking 1. Install concrete thrust blocking at pipe bends, tees, fire hydrants, and other locations shown on the Drawings. Place the concrete between solid ground and the fitting to be anchored. Care shall be taken to place the thrust block such that the pipe and fitting joints will be accessible for repair. 2. The shape and contact area of the concrete thrust blocks shall be as shown on the Drawings and as directed by the Engineer. The contact area of backing shall be as required to prevent movement of the joint, but in no case shall the contact area be less than one square foot. D. Connections to Mains 1. Connect new water mains to existing mains as shown on the Drawings. 2. Prior to valving off the existing main, assemble all equipment and fittings before excavating and exposing the main. Coordinate closing and opening of valves with the Utility. Connect to the new main using adapters and fittings specified. Bedding, backfilling, concrete blocking and other related items shall be as specified in other sections of this specification. 3. The main shall be connected and a corporation stop installed near the point of connection to permit expelling air from the line. Installation of the tap shall be as directed by the Engineer.

PIPE INSTALLATION. A. General: Unload Proper implements, tools, and facilities shall be provided and used for the safe and convenient performance of the work. All pipe, fittings fittings, valves, and accessories near hydrants shall be lowered carefully into the place where they are trench by means of a ▇▇▇▇▇▇▇, ropes, or other suitable tools or equipment in such a manner as to prevent damage to pipeline material and protective coatings and linings. Under no circumstances shall pipeline materials be laid dropped off or dumped into the trench. The trench should be dewatered prior to installation of the pipe. B. All pipe fittings, valves, hydrants, and other appurtenances shall be examined carefully for damage and other defects immediately before installation. Defective materials shall be marked and held for inspection by the engineer who may prescribe corrective repairs or reject the materials. C. All lumps, blisters, and excess coating shall be removed from the socket and plain ends of each pipe, and the outside of the plain end and the inside of the bell shall be wiped clean and dry and be free from dirt, sand, grit, or any foreign material before the pipe is laid. D. Foreign material shall be prevented from entering the pipe while it is being placed in the trench. During laying operations, no debris, tools, clothing, or other materials shall be placed in the pipe. E. As each length of pipe is placed in the trench, the joint shall be assembled and handle with care the pipe brought to avoid damagecorrect line and grade. Cutting of The pipe shall be done by means of an secured in place with approved type of mechanical cutterbackfill material. B. Placement of Pipe: 1. Clean and inspect all sections of pipe, fittings and accessories for damage immediately prior to placement in the trench. Reject all defective materials, and remove them from the project.

Jointing of mechanical-joint pipe shall be accomplished such that the gland is positioned evenly by tightening alternately the bolts spaced 180 degrees apart. 3. F. At times when pipe laying is not in progress, close the open ends of the pipe with a watertight plug. This provision shall apply during the lunch period, overnight, or any other time when work is not in progress. 4. No pipe shall be laid in wet trench conditions that preclude proper bedding, closed by a watertight plug or on a frozen trench bottom, or when in the opinion of other means approved by the Engineer. When practical, the plug shall remain in place until the trench conditions or the weather are unsuitable for proper installation. C. Concrete Thrust Blocking 1. Install concrete thrust blocking at pipe bends, tees, fire hydrants, and other locations shown on the Drawings. Place the concrete between solid ground and the fitting to be anchoredis pumped completely dry. Care shall be taken to place prevent pipe flotation should the thrust block trench fill with water. G.
