reference
OM-631 is one of the references used in the Facility and Fixture (F&F) Handbook developed by the U.S. Army Corps of Engineers (USACE). This reference defines the F&F materials and design criteria to be used in constructing military facilities. The OM-631 covers the design criteria and requirements for the different components of a facility that includes floors, walls, and roofs. The reference also provides guidance on fireproofing, insulation, air barriers, and acoustical treatments. Additionally, it provides guidance on structural and seismic requirements, as well as requirements for building envelope construction, among other related topics.
