3-5.1.3 Preferred exterior doors are hollow metal in hollow metal frames, with
aluminum doors in aluminum storefront systems for major entries. Exterior windows
should be steel or aluminum frame units, or storefront assemblies where large areas of
glazing are desired.
3-5.1.4 The preferred roof construction is a sloped standing seam metal roof or 50
year shingle except at the kitchen, where a low-slope ("flat") roof better accommodates
the kitchen equipment rooftop penetrations and equipment. See guidance on standing
seam metal roof systems (SSMRS) and 50 year shingle in Appendx K. Low slope roofs
are an acceptable design solution when the Using Agency and USAR Installation
approve, or where budget limitations dictate. Modified bitumen or single-ply membrane
roofing will be used for low-slope roofs.
3-5.1.5 Preferred interior walls are steel stud with gypsum board for spaces where a
more pleasant finish is desired, or CMU. CMU walls may be GMU or painted CMU.
Consideration should be given to space function and volume of traffic; in high traffic
areas and areas where wear and tear can be anticipated, it may be desirable to use
GMU if a nicer finish is desired. It may be helpful to consider wear and tear in an USAR
training center to be similar to that anticipated in a high school or college building, and
use in an OMS to be similar to a repair garage.
3-5.1.6 Interior doors should be either solid-core wood or hollow metal in hollow metal
frames. Offices and similar spaces with higher levels of finish should receive wood
doors; more utilitarian areas can utilize hollow metal doors. The arms vault door must be
a \ GSA approved Class 5-V vault /2/ door. Doors must have a minimum clear opening
of 3 feet (900 mm) in width.
3-5.1.7 Most spaces with ceilings will be suspended acoustical tile; the USAR
preference is for 24 inch by 24 inch (600 mm by 600 mm) tiles to avoid sagging of tiles.
Areas where higher humidity is anticipated should receive a suspended gypsum board
ceiling. Ceilings for kitchen and shower areas will be suspended cement board with
water resistant skim coat
3-5.1.8 In general, the materials and methods of construction
proposed for use on USAR facilities should be of high quality
and will have been used (preferably by the Design Agency) in
several projects which can be researched to ascertain the
product s performance characteristics. Materials, as well as the
design, should be of good quality and able to stand the test of
3-5.2.1 Both the exterior and the interior image of USAR facilities should reflect
military values, such as dignity, tradition, discipline and order. At the same time, they
should provide the Tenants a functional and comfortable workplace, and an atmosphere
which will promote feelings of pride and ownership.
