City of Seattle

Airport Way Center, Building E

The City of Seattle (City) requested our expertise to conduct a facility evaluation at Airport Way Center (AWC), Building E. The design team was responsible for assessing conditions of the existing facility, providing recommendations and cost opinions for specific areas of renovation.

Based on the findings report, the City chose to replace the roof and perform selective envelope improvements.  The project was split into 2 separate bid packages: roof replacement and envelope upgrades. Building E houses the water quality lab for the City of Seattle. To minimize disruptions to facility operations, roof work was scheduled around the exhaust fans serving the laboratory fume hoods.
