e) Limitations on materials by Department of Defense, Bureau of
the Budget, or other mandatory standards.
f) Mandatory standard drawings and specifications for certain
types of buildings, such as ammunition magazines.
g) Criteria for design of structures in typhoon, hurricane, and
other high wind areas as described in NAVFAC DM-2.01.
3.5.3.2
Conventional Construction. Conventional column/beam/truss
construction or pre-engineered designs may be used for buildings up to 44
feet (13 410 mm) in height.
Rack Supported Construction. Rack supported construction, in which
3.5.3.3
the storage (pallet rack) system provides the building support in the storage
area, shall be evaluated for all structures over 44 feet (13 410 mm) in
height. For lower buildings, this method of construction shall be reviewed
for economic suitability.
3.5.4
Roof. The following criteria apply:
a) Combustible roofing is permitted only in emergency construction.
b) Roofing construction may consist of steel decking, reinforced
concrete, or precast concrete panels.
c) Gutters and downspouts shall be used. Positive measures must
be taken to prevent accumulations of mud, snow, or ice.
d) Refer to Engineering and Design Criteria for Navy Facilities,
NAVFAC P-34, for standards concerning materials and installation for built-up
roofing. Insulate roofs in accordance with DOD 4270.1-M.
Flat Roofs. Flat roofs shall be used to minimize potentially
3.5.4.1
unusable space caused by the roof rise associated with sloped roofs. Flat
roofs shall have a minimum pitch of of l/2 inch per foot (42 mm per meter).
3.5.4.2
Sloped Roofs. Sloped roofs having a pitch exceeding 1 inch per
foot (83 mm per meter) shall be avoided for covered storage facilities unless
available roofing materials require a greater pitch. Sloped roofs having a
pitch of 3-4 inches per foot (250-333 mm per meter) may be used in small
spans where roof rise can be limited to 5 feet (1525 mm) or less. Sheds may
have a roof pitch of 2 inches per foot (166 mm per meter) or greater.
3.5.5
Exterior Walls. Exterior walls may be of insulated metal siding,
brick or concrete masonry, or tiltup precast or cast-in-place concrete
panels. When metal walls are used, the first 4 feet (1220 mm) of wall above
the floor shall be of reinforced masonry construction to protect the
structure from fork truck impact and provide additional security (see
Figure 17). Walls located on sides designated for future expansion shall be
removable.
Interior Walls. Interior wall construction will vary depending
3.5.6
upon use, finish, and required fire and corrosion resistance. Refer to
NAVFAC P-34 for specifications for the following:
a) Lath and Plaster
