Emergency Generator Replacement at Various Fire Stations

Emergency Generator Replacement at Various Fire Stations LABELING AND IDENTIFYING A. Detectable Warning Tape: Acid- and alkali-resistant, PE film warning tape manufactured for marking and identifying underground utilities, a minimum of 6 inches (150 mm) wide and 4 mils (0.1 mm) thick, continuously inscribed with a description of utility, with metallic core encased in a protective jacket for corrosion protection, detectable by metal detector when tape is buried up to 30 inches (750 mm) deep; colored yellow. PART 3 - EXECUTION 3.1 OUTDOOR PIPING INSTALLATION A. Comply with NFPA 54 and the International Fuel Gas Code for installation and purging of natural-gas piping. 3.2 INDOOR PIPING INSTALLATION A. Comply with NFPA 54 or the International Fuel Gas Code for installation and purging of naturalgas piping. B. Drawing plans, schematics, and diagrams indicate general location and arrangement of piping systems. Indicated locations and arrangements are used to size pipe and calculate friction loss, expansion, and other design considerations. Install piping as indicated unless deviations to layout are approved on Coordination Drawings. C. Arrange for pipe spaces, chases, slots, sleeves, and openings in building structure during progress of construction, to allow for mechanical installations. D. Install piping in concealed locations unless otherwise indicated and except in equipment rooms and service areas. E. Install piping indicated to be exposed and piping in equipment rooms and service areas at right angles or parallel to building walls. Diagonal runs are prohibited unless specifically indicated otherwise. F. Install piping above accessible ceilings to allow sufficient space for ceiling panel removal. G. Locate valves for easy access. H. Install natural-gas piping at uniform grade of 2 percent down toward drip and sediment traps. I. Install piping free of sags and bends. J. Install fittings for changes in direction and branch connections. K. Verify final equipment locations for roughing-in. L. Comply with requirements in Sections specifying gas-fired appliances and equipment for roughing-in requirements. M. Drips and Sediment Traps: Install drips at points where condensate may collect, including service-meter outlets. Locate where accessible to permit cleaning and emptying. Do not install where condensate is subject to freezing. 1. Construct drips and sediment traps using tee fitting with bottom outlet plugged or capped. Use nipple a minimum length of 3 pipe diameters, but not less than 3 inches (75 mm) long and same size as connected pipe. Install with space below bottom of drip to remove plug or cap. N. Extend relief vent connections for service regulators, line regulators, and overpressure protection devices to outdoors and terminate with weatherproof vent cap Multiple Locations Are Available In This Project.
