VHA PROGRAM GUIDE PG-18-3
April 2001
TOPIC 5. PIPE BASEMENTS
1. GENERAL: Evaluate the use of full or partial pipe basements on an individual project basis
through a design analysis of the most efficient and economical method of adapting piping, duct, and
electrical conduit systems to the building. Design pipe basements to provide a minimum clearance of
1200 mm (4 ft.) under pipes, ducts, and electrical conduits for access to these systems for maintenance
and repair. Provide pipe basements with two means of egress. Provide a means of access for personnel
and equipment.
2. CONSTRUCTION
a.
Insulate the exterior pipe basement walls to prevent freezing temperatures for locations where
ambient temperatures are -7C (20F) or below.
b. Provide access to the pipe basement at stairwells and emergency egress to the exterior through
the use of areaways where necessary.
3. HEATING AND VENTILATION
a.
Provide thermostatically controlled mechanical ventilation to prevent excessive rise in basement
temperature and/or prevent moisture problems.
b. Provide intake louvers with dampers of sufficient size to satisfy fan requirements.
c. Screen all ventilator and louver openings to prevent entry of insects and small animals.
d. As dictated by design computations for maintaining slab at 21C (70F), provide heating in the
pipe basement or insulate the slab or both.
