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.
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 which 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 Extra Hazard Occupancy (Group
1) as defined 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 in seismic zones 3 and 4 as defined by UBC and where "Z" values
per VA Seismic Design Requirements PG-18-03 for the specific VA site are 0.20 or greater.
The following list identifies the "Z" values from the handbook (1999). Check the handbook
for updated information.
