North Transfer Station Rebuild
Awarded the prestigious IDEAS2 National Award by AISC, the North Transfer Station is Hailed as one of America's most striking and community-oriented waste management facilities. This innovative project, located in Seattle's Wallingford neighborhood, includes a new 67,000 sq. ft. tipping and transfer building, a 10,000 sq. ft. reuse/recycle building, and a 2,400 sq. ft. administration building.
Project Highlights
Integrated Design Engineers faced the challenge of creating a structure with a 200-foot clear span while adhering to Seattle Public Utilities' height restrictions. Their solution was a tri-chorded roof truss system, which not only met the height requirements but also achieved exceptional LEED daylighting credits.
A standout feature of the design is the "floating corner" a 50-foot cantilever truss and a 120-foot main transfer truss system that supports the building's southwest corner without any columns or walls. This innovative design allows for unobstructed truck access to the building's lower level.
Project Praise
“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.
