RE: Federal Way Campus - Woodbridge Building A and B
Weyerhauser Way S, Federal Way, WA
Scott,
This letter is to request a code exception as it relates to 3rd Party Review Comments from WC3 received 6/15/22, for
Federal Way Campus projects Woodbridge Building A and B.
The 3rd Party Review comments for both buildings indicate that because the buildings are Type 3B construction, per IBC
704.10, the exterior columns supporting the main entry canopy must have the same fire rating as the exterior bearing walls
in IBC Table 601 which calls for 2-hour fire rating. It is important to indicate that the design of the non-combustible canopy
and trellis was in response to the City of Federal Way’s request for a more aesthetically pleasing entry. The large non-
combustible structural columns supporting the canopy and trellis structure are designed in a way to provide visual interest
more so than supporting a 250 SF canopy.
We understand that Chapter 7 of 2015 IBC is to safeguard against spread of fire/smoke within a building or to/from
buildings. Per section 104.10 Modifications, we request an exception to the building code given the materials outside of the
main building are of non-combustible material, continuation of EFSR sprinkler system under the 250 SF canopy, and more
than 60’ away from any other adjacent buildings/property.
See attached Exhibit showing location and elevations of concerned area.
If there are any questions or you would like to discuss, please call myself at (206) 408.8646.
Regards,
Patrick Carty, Project Manager
