The plan review was performed under the State of Oregon Structural Specialty Code (OSSC)
2004 edition, Oregon Fire Code 2004 edition; and NFPA 13. The submitted plans are approved
subject to the following.
HYDROSTATIC TESTING
Hydrostatic testing of the system shall occur at sprinkler final. The contractor's
material and test certificate required by NFPA 13, 16.1 shall be completed and signed
by both the installer and building owner. Failure
TESTING: - Section 16.2.1
1. Unless permitted by 16.2.1.2 through 16.2.1.6, all piping and attached appurtenances
subjected to system working pressure shall be hydrostatically tested at 200 psi (13.8 bar)
and shall maintain that pressure without loss for 2 hours. Loss shall be determined by a
drop in gauge pressure or visual leakage. The test pressure shall be read from a gauge
located at the low elevation point of the system or portion being tested.
WATERFLOWALARMS: - Section 6.9.1
7. Water flow alarm apparatus shall be listed for the service and so constructed and installed
that any flow of water from a sprinkler system equal to or greater than that from a single

modified as specified in the individual product listings.
SWAY BRACING: - Section 9.3.5 - 9.3.5.8
16. The system piping shall be braced to resist both lateral and longitudinal horizontal
seismic loads and to prevent vertical motion resulting from seismic loads. The structural
components to which bracing is attached shall be determined to be capable of carrying
the added applied seismic loads. Sway braces shall be designed to withstand forces in
tension and compression. Bracing shall be attached directly to feed and cross mains.
17. For feed and cross mains, longitudinal sway bracing shall be spaced a maximum of 80 ft.
Later -al sway bracing shall be spaced a maximum of 40 ft. A length of pipe shall not be
braced to sections of the building that will move differentially.
SPARE SPRINKLERS: - Section 6.2.9

follows:
a. For systems having less than 300 sprinklers, not fewer than six sprinlders
b. For systems with 300 to 1000 sprinlders, not fewer than 12 sprinlders
c. For systems with over 1000 sprinlders, not fewer than 24 sprinklers
Approved Plans: 1 set of approved plans, bearing the City of Tigard approval stamp, shall be
maintained on the jobsite. The plans shall be available to the Building Division inspectors
throughout all phases of construction. 106.3.1 OS SC
