King County Metro continues its commitment to sustainability with a call for companies to design and construct a charging facility for our growing fleet of battery-electric coaches. This project advances King County’s progress toward having a 100% zero-emissions transit fleet by 2040 or sooner.

The Interim Base Electrification project includes design and construction of electrical power infrastructure (in coordination with Seattle City Light), charging infrastructure, charge management systems, and other elements required to support the charging operations for 120 battery-electric buses at King County’s Interim Base at South Campus located in Tukwila. The project is scheduled to be completed by 2024 and is part of the overall expansion of Metro’s South Campus.

Metro, contingent on approval from the Washington State Department of Enterprise Service, will be issuing a Request for Qualification (RFQ) and a Request for Proposals (RFP) using the Progressive Design Build procurement method.

To encourage early teaming arrangements, Metro is hosting town hall meetings on Tues. Jan. 12 and
 Fri. Jan. 15 for interested parties.
