RE: Stevens Health Care Center Request for Alternate Design
HVAC Equipment within a Corridor
Dear Mr. Grimes,
GARY HAAKENSON
MAYOR
May 24, 2007
The City is in receipt of your request for Alternate Design; the submittal includes your letter dated
April 17, 2007, a corridor detail dated May 23, 2007, a letter from ABSCO Alarms dated April 16,
2007 with corresponding fire alarm system upgrade plans and a letter from ACCO Engineered Systems
the Mechanical Engineer of Record dated May 22, 2007. The owners of the building voluntarily
approached the City once the non -conforming corridor condition was brought to their attention and as
responsible owners they desire to provide corridor protection to all building occupants and the City
commends their actions to date.
In reviewing the request it is apparent that the existing physical dimensions and obstacles within the
plenum area above the corridor prohibit strict compliance to international Building Code Section
1016.4 and International Mechanical Code 601.2 (WAC Amendment). The proposal to use
interconnected fire/smoke dampers as an early detection measure together with complying elements of
corridor construction address the issue of code equivalency. Therefore, it is my determination as
Building Official for the City of Edmonds the alternate design request is hereby APPROVED with the
following conditions:
Mechanical permit application #2006-1088 must be obtained, plans shall clearly show the
relocation and alteration of the HVAC heat pump units and associated duct work within the
corridor, including installation of fire/smoke dampers on both supply and return air systems.
Fire Alarm permit application #2007-0258 must be obtained, (the City shall process the plans
dated 5/4/07 as a resubmittal to the permit application). At the end of the project, as -built plans
shall be provided to reflect any heat pumps/damper locations that are adjusted during
implementation as well as updated zone maps to reflect any shift in position.
Sincerely,]
Jeannine L. Graf, C.B.O.
Building Official
