Appeal Information Sheet

Appeal item 1

Code Section

PORTLAND FIRE & RESCUE Fire Design Manual

Requires

The Portland Fire & Design Manual requires that all systems must be designed using 80% of the normal maximum static pressure unless otherwise approved by the Fire Marshal’s Office.

Code Modification or Alternate Requested

This appeal proposes to use the actual flow test data taken from private hydrants on campus for the fire sprinkler design with a 10% safety reduction.

Proposed Design

The attached flow test data would be utilized for the fire sprinkler design with a 10% safety. The test data was taken from the private hydrants on the Portland Community College Sylvania campus. The private hydrants are on the discharge side of the site fire pump.

Reason for alternative

An actual flow test likely provides more accurate data for campus style arrangements. The 29 PSI static pressure to use for design provided by the attached Portland Water Bureau model is a 7 PSI reduction from the 36 PSI maximum static pressure. Utilizing a 10% safety on the test results taken from the actual flow test would results in an 8 PSI static pressure reduction. Therefore the 10% reduction from the actual flow test would result in a larger reduction in pressure and provide more safety.
