Field Measurement: The Drawings are in general indicative of the Work, with symbols and notations for clarity. However, the Drawings are not an exact representation of all conditions involved, therefore, layout Piping to suit actual field measurements. No extra compensation will be made for Work due to difference between indicated and actual dimensions ARRO

5 3.02 INSTALLATION A. General: Run piping concealed in those areas of the structures having hung ceilings and exposed in all other areas, except where indicated otherwise on the Drawings. 1. Run piping parallel or perpendicular to the lines of the building structure. Keep piping a sufficient distance from other work to permit clearance of not less than one inch between the piping or insulated piping and adjacent work. 2. Install piping as close as possible to walls, overhead construction, columns, and similar to facilitate insulating work and removal of piping later. 3. Clean piping prior to installation and following installation to prepare for painting. Keep open ends of piping and pipe attachment openings on equipment capped or plugged until actual connections. B. Interferences: Run piping to compensate for structural interferences, to preserve headroom, and not to interfere with openings, passageways and equipment. Do not install piping with joints and fittings over motors, switchboards, panels, or similar electrical apparatus CONSTRUCTION METHODS A. General: 1. Construct pipe runs from full lengths of pipe using short sections only for runs of less than full pipe length. Make changes in directions of pipe runs with fittings only. 2. Install unions and flanges in accessible locations and whether indicated or not, install union adjacent to all equipment and wherever removal of equipment for repair or replacement is required. Use dielectric unions at points of connection of copper tubing and piping to ferrous metal piping or equipment. 3. Use reducing fittings where reduction in pipe sizes is necessary. Bushings will not be accepted. 4. Cut pipe accurately to measurements established in the field and assemble in place without springing, forcing, excessive cutting or weakening of the structure. B. Underground Piping: 1. Keep trenches dewatered until pipe joints have been made and concrete bedding and blocking, if any, have hardened. Under no circumstances lay pipe in water or on subgrade containing frost. 2. Rest each section of pipe on pipe bedding for the full length of its barrel, with recesses excavated for pipe bells so joints can easily be made. Backfill recesses with bedding material immediately following pipe joining operations. 3. Take up and relay pipe that is not laid true to required alignment or grade or has its joints disturbed after laying. No deviations from the required line and grade permitted, except with approval of the Engineer ARRO

6 3.04 PIPE JOINING A. General: Exercise care when making pipe joints and make joints in accordance with the pipe material manufacturer s recommendations and the following requirements. 1. In each instance of pipe joining, those portions of pipes involved must be absolutely clean just prior to assembly. 2. If a joint is extremely difficult to assemble or sealing is not affected, disassemble the joint and correct the difficulty if possible. Remake the joint using new materials when necessary. B. Copper Tubing and Pipe Joints: Cut tubing and piping ends square, deburr, and ream to size of original bore. 1. Solder: Prior to sweating, clean pipe ends and fitting surfaces involved in the joint, to bright metal without marring surfaces. Finished joints shall show no evidence of hard-temper due to over-heating, no evidence of improper solder draw, and excess solder must be removed. 2. Flared: Cut tubing and piping ends square, deburr and ream to size of original bore. Finished joints shall show evenness of flaring and proper seating of joining parts. C. Ferrous Metal Piping Joints: Cut pipe ends square, deburr and ream to size of original bore. 1. Threaded: Cut threads to standard gage depth and length and clean threads free of oil and cuttings. Use Teflon (DUPONT) formulation joint tape or Teflon joint paste to aid in joint lubrication and sealing in joining operation. 2. Welded: Responsibility for quality of welding, competency of welding operators and their ability to make sound welds rests with the Contractor. Technique of welding employed, appearance and quality of welds made and methods used in correcting defective work shall conform with requirements of ANSI B31.1 and its Supplements. 3. Flanged: Face accurately, install gaskets and draw up square and tight to ensure full gasket flow and seal. D. Solvent-Weld (PVC Pipe) Joints: Use chemical solvent welding components as recommended by the pipe material manufacturer and comply with said pipe manufacturer s cleaning and joining instructions PIPE LINE SUPPORT A. Installation: Place and support piping runs as specified in Section END OF SECTION ARRO
