Convention Place Station
Seattle, Washington
Client: King County Metro

The current Convention Place Station transit facility and northern portal to the Downtown Seattle Transit Tunnel needs to be relocated to accommodate the Washington State Convention Center expansion. Parametrix is providing construction management, inspection, project controls, and technical support to King County Metro Transit for the replacement and relocation of transit systems. The work is being accomplished through GC/CM contract packages jointly awarded and negotiated by Metro and the Washington State Convention Center. These include both temporary and permanent facilities to allow the convention center work to progress as quickly as possible. Work has included replacement of the main traction power substation serving Metro’s trolley fleet in downtown Seattle, replacement of transit tunnel systems, temporary access, and street improvements on a fast track basis – a total project value of $15 M.
