Investigate if credit can be obtained from the public utility
company for water consumed, but not discharged into the sanitary
sewerage system. If so, and adequate pressure is available,
provide meters for these users. Examples of users are the
irrigation system, cooling towers, boiler make-up, and liquid ring
compressors and vacuum pumps.
2.
GENERAL
2.1
Design the plumbing and medical gas systems to comply with this
criteria, and the current edition of 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.
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.
