Fire Protection Design Manual - Office of Construction and Facilities ...

September-2011
F. Delineate on the drawings special conditions such as storage racks/shelving location, height
and configuration (including mobile shelving); atria; open ceilings, or architecturally
sensitive areas; audiometric booths; walk-in freezers and cold rooms; computer rooms and
raised flooring; loading docks and exterior canopies; residential sleeping etc. which may
have an impact on sprinkler design and installation.
G. Coordinate with the facility and show smoke zone boundaries, hazard classification, density,
and other special requirements on drawings. Sprinkler zones shall coincide with all smoke
zone boundaries within health care occupancies.
Note: Since the sprinkler contractor is required by NFPA 13 to hydraulically calculate the
system and provide working drawings, this effort should not be duplicated by the A/E. Some
items commonly not identified on the drawings that create problems are drain terminations,
hazard classification, smoke zone boundaries, and water supply hydraulic information. The
contractor needs to know where to start, what water supply is available, the commodities
being protected, what area is supplied by each flow switch, and special circumstances such
as areas subject to freezing and combustible concealed spaces.
H. Rooms containing bulk supply storage shall be classified as required by NFPA 13. If
provided by the contract, storage racks shall utilize open shelving systems. Ensure shelving
which obstructs sprinkler water from penetrating down through racks is not used.
I. Provide seismic protection when the building is in an area of Moderate High, High, or Very
High seismicity as identified in the map below taken from VA Seismic Design Requirements
H-18-8. (Refer to H-18-8 for updated requirements. See
http://www.cfm.va.gov/til/etc/seismicmap.pdf for latest version.)
