ASEI Wins Mechanical Construction Award
TACOMA, WA Working with General Contractor Sierra Construction Company, Inc., Air Systems Engineering Inc. (ASEI) performed the design/build for the new mixed-use building on Tacoma, Washington's, Thea Foss Waterway. The 161-unit project includes two levels of concrete parking garages with five levels of wood framing above.
A major challenge to this project was designing a sound-sensitive building to shield residents living just 40 feet from heavily-used railroad tracks and next to the I-705 Bridge. To subdue the noise level, the building's exterior walls were heavily insulated and high noise reduction coefficient windows were used throughout. To bring outdoor ventilation into the building, ASEI designed a system using duct board as a sound attenuator with a telescope-type duct system that allows fresh air in with a minimum of noise.
An additional challenge was fabricating a 70-foot welded grease duct with access doors to be installed down a shaft for a future restaurant. ASEI teamed with Magnum Crane to lift and safely place the two sections of the duct into the shaft.
Building amenities include new gas barbeques, a large patio fire pit and a fireplace for the community room. ASEI incorporated electronic solenoid valves and timers on the gas lines that automatically shut off each unit at the end of each night as a safety precaution. The project owner was pleased with the result and signed maintenance agreements with ASEI.
There were no time-loss or medical injuries during the 2,076 hours worked.
The ABC members that worked on this project were: Evergreen Concrete Cutting, Omni Duct System, Pacific Metal Company, Paragon Pacific Insulation and Star Rentals.
