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.
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. Section 16.2.1
2. 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 automatic sprinkler of the smallest orifice size installed on the system
will result in an audible alarm on the premises within 5 minutes after such flow begins
and until such flow stops. Section 6.9.1
3. Sprinklers for each spray area shall be controlled by a separate, accessible, listed
indicating valve. Section 13.4.2.1
4. Sprinklers protecting spray areas shall be protected against overspray residue.

5. 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. Section 9.3.5 - 9.3.5.8
6. The stock of spare sprinklers shall include all types and ratings installed and shall be as
follows: a. For systems having less than 300 sprinklers, not fewer than six sprinklers.
Section 6.2.9
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 OSSC
When submitting revised drawings or additional information, please attach a copy of the
