NORTH TRANSFER STATION REBUILD
Recognized by AISC with the IDEAS2 National award, the North Transfer Station may be the most beautiful and community-friendly dump in America. The project is comprised of a new tipping and transfer building (67,000 sf), a reuse/recycling building (10,000 sf), and an administration building (2,500 sf) located in Seattle’s Wallingford neighborhood.
Integrated Design Engineers was tasked with developing a building structure that allowed a 200-ft clear span that did not exceed SPU’s community building height agreement. Our solution was a tri-chorded roof truss system that also earned the project exemplary LEED daylighting credits.
We also developed the “floating corner,” a 50-ft cantilever truss and a 120-ft main transfer truss system that supports the weight of the entire building at its southwest corner. This upper-level corner - supported without any columns or walls - allows trucks access into the building on the lower level.
“A truly innovative, creative solution to program requirements that shows advances in the use of structural steel.”
— Jeff Yoders, Engineering News-Record magazine
“Overall, the steel elements create an organizational framework and visual interest that defines the open space and thus becomes a significant part of the architectural aesthetic.””
— Lead Architect, Mahlum.
