3.01 PREPARATION A. The layout of some of the piping systems shown on the drawings may be diagrammatic, but shall be followed as closely as the work will permit. The Contractor shall field verify the location and size of existing pipe utilities. B. Before running lines, the Contractor shall carefully verify location, type of joint needed and size of pipe to which connection is proposed. He shall then assure himself that the lines can be run as contemplated without interfering with footings, walls, other piping, and utilities etc. Any necessary deviation shall be referred to the Engineer for final adjustment before installation. C. All lengths of pipe shall be dimensioned accurately to measurement established at the site, and shall be worked into place without springing or forcing. Cut sections of pipe shall be reamed to remove all burrs. D. Utmost care shall be exercised in loading, and placed of all pipe, fittings, valves, etc., in order to avoid shock and/or damage. Lifting shall be by hoist or skids when hand lifting is not feasible. Dropping will not be permitted. Pipe handled on skidways must not be skidded or rolled against pipe already on the ground. E. Any pipe, special castings, or other appurtenances broken or damaged in transit to the site where they are to be used, or after they have been delivered to the site, shall be replaced by the Contractor at his own expense. F. All pipes and special castings shall be carefully examined for defects, and no pipe or special casting shall be laid where is known to be defective. If any such pipe or special casting shall be discovered to be defective after being laid, it shall be removed and replaced with a sound casting by the Contractor at his own expense. G. The Contractor shall cut all pipe and drill all holes that may be necessary, whenever and wherever so required. This work shall be done in a thorough and workmanlike manner. H. The pipe shall be kept clean. All foreign material shall be removed from the inside of the pipe before it is placed. 3.02 INSTALLATION OF PIPING A. Lines, Grades, Stakes and Templates: 1. The Contractor shall, at his own expense, furnish all templates, patterns, platforms, and labor that may be required in the layout of any part of the work. 2. The Engineer will furnish, upon request by the Contractor, limit marks and bench marks reasonably necessary for the execution of the work. 3. The Engineer will furnish a representative to check alignment and grade after it has been laid out ready for construction; however, this will in no way lessen the responsibility of the Contractor to maintain correct grade and alignment at all times. 08/12 02610-4 11-4179
