contained in VA Program Guides PG-18-4 and PG-18-6 and Program
Guide 7610 are to be noted on or immediately adjacent to each unit
of shelving, casework, etc. However, when 1:50 (1/4") scale
equipment floor plans are drawn for certain rooms or areas, show
the proper symbols on these plans and not on the 1:100 (1/8")
scale plans. Show numerical designations ("P" numbers) for
plumbing fixtures on plumbing drawings only, not on architectural
drawings.
3.3
Use VA Program Guide PG-18-4, National CAD Standard Details, as a
guide only, except for:
a.
National CAD Standard Details specifically stipulated by VA
Program Guide PG-18-3, Design and Construction Procedures.
b.
National CAD Standard Detail 08100-1 and 08100-2, VA Door
Schedule, which must be used unless VA's project manager
specifically approves use of another system.
3.4
Use fire protection symbols for fire-rated and smoke-barrier
partitions, as indicated in PG-18-4, on the 1:100 (1/8")
architectural floor plans where the partition types are
designated, and on the fire protection plans.
3.5
Show all floor drains on the 1:100 (1/8") architectural plans.
Because of possible problems from sewer gases, the number of floor
drains is to be minimized. Nevertheless, floor drains should be
provided in all locations where indicated in the Equipment Guide
List, Program Guide 7610. Floor drains should also be provided at
walk-in refrigerators and controlled temperature rooms for
condensation return. Pitch of floor to drains shall be indicated
on the 1:100 (1/8") scale drawings only.
3.6
Comply with VHA National CAD Standard Application Guide and
applicable National CAD Standard modules.

BUILDING PERIMETER FOUNDATION DRAINAGE
4.1
Subsoil (foundation) drainage provides a means of removing water
that may percolate to the footing level of a building foundation
system. Establish the need for a subsoil drainage system by an
analysis of the climate, topography, soil character, water table,
geological factors and the judgment of the designer. Where
topographical or other factors exist which would lead to
uncertainty regarding the ability of natural drainage to function
and avoid damage by subsurface water, provide a subsoil drainage
system and show it on the architectural basement floor plans.
Sections must show relative elevations compared to basement floor
level.
4.2
Provide subsoil drains, when judged advantageous and where
individually required, at building perimeter wall footings
adjacent to basement, crawl spaces, or pipe basements below grade.
4.3
Subsoil drains shall maintain a pitch as uniform as possible and
shall drain to suitable outfall. Minimum pitch shall be 1/2 of
1%.
