PART 3 EXECUTION
3.1 EXAMINATION
Examine rough-in for fire cabinets and sprinklers to verify
actual locations of piping connections prior installing.
Examine walls for suitable conditions where cabinets are to be
installed. Examine ceiling pattern, air diffusers and grills, light
fittings, for suitable conditions where sprinkler are to be
installed.
Do not proceed until unsatisfactory conditions have been
corrected.
3.2 PIPING INSTALLATIONS
Drawings (plans, schematics and diagrams) indicate the general
location and arrangement of piping systems. So far as practical,
install piping as indicated. Deviations from approved "Working
Plan" for piping require written approval of the Engineer.
Install sprinkler piping to provide for system drainage in
accordance with NFPA 13.
Use approved fittings to make all changes in direction, branch
takeoffs from mains and reductions in pipe sizes.
Install unions in pipes 50 mm and smaller adjacent to each
valve. Unions are not required on flanged devices.
Install flanges or flange adapters on valves, apparatus and
equipment having 65 mm and larger connections.
Provide hangers and supports in Compliance with the
requirements of NFPA 13, NFPA 14 and Section 15145.
Make connections between underground and above-ground
piping using an approved transition piece strapped or fastened to
prevent separation.
