The new 35,000-square-foot maintenance and engineering building will help consolidate operations. Miller Hayashi Architects is the architect.

Plans are moving ahead to consolidate the city of Tukwila's Public Works operations onto a single 10.8 acre campus.

Last week, the city issued a determination of non-significance for the Tukwila Maintenance and Engineering East Campus Project, which will unify five adjacent parcels, generally referred to as the West Campus and the East Campus, located at 11210 Tukwila International Blvd. and 11231 East Marginal Way S.

Construction is planned to begin in summer 2025. Cost is estimated at about $80 million.

The project includes a new 35,000-square-foot, three-story maintenance and engineering building with shops, offices, meeting rooms and support spaces. There will also be new 5,000-square-foot tool storage building with drive-through truck loading, and a new 2,600-square-foot decant facility.
