GENERAL
2.1
Design the plumbing and medical gas systems to comply with this
criteria, and the current VA Design and Construction Procedures,
VA Program Guides, and VA Master Specifications. Design shall also
meet the provisions of the current edition of the National
Standard Plumbing Code as published by the National Association of
Plumbing-Heating-Cooling Contractors, and the National Fire Codes
as published by the National Fire Protection Association (NFPA),
unless VA criteria indicates otherwise. If state or local codes
are more stringent than above requirements, discuss with VA
Contracting Officer.
2.2
Show plumbing work on drawings using a minimum scale of 1:100
(1/8" = 1'-0'). Exceptions shall be indicated at a scale of 1:50
(1/4" = 1'-0").
2.3
Identify rooms on plans with name and number.
2.4
Investigate and, if feasible, connect new services to existing;
otherwise, provide new services.
2.5
Identify on the plumbing drawings all equipment requiring
connections to the plumbing systems by appropriate symbol number
(example P-103). Do not use the designation N.I.C. on the
drawings.
2.6
All equipment shall be placed on housekeeping pads.
2.7
Due to the space requirements of plumbing systems and ductwork,
closely coordinate the layout of these systems. Where areas of
interference are apparent, prepare cross section of building
showing method of installation.
2.8
Piping over operating rooms; food preparation, serving and storage
areas; and electrical rooms containing main distribution panels or
motor control centers shall be avoided where possible. When piping
is necessary in these areas, indicate leakage protection on
drawings or in specifications.
