Stantec/Hensel Phelps Team Completes Construction for Sound Transit’s New Light Rail Base

Sound Transit recently completed construction of its new Operations and Maintenance Facility: East (OMF East), which will service, maintain, store, and deploy Link light rail vehicles for its growing fleet in the Puget Sound area. As Sound Transit’s light rail service area grows through 2024, the vehicle fleet will expand from its current 62 vehicles to 214. The new OMF East will enable extensions to Lynnwood, Federal Way, and Redmond, Washington. The facility was delivered by the design-build team of Stantec, Hensel Phelps Construction Co., and partners. Construction started in 2018.

The 145,000-square-foot OMF East facilities provide 14 service bays, a cleaning and wash bay, shop areas, parts storage, and office space. The facility includes seven overhead bridge cranes and six monorail hoists. This new Eastside facility supplements the existing Link OMF in Seattle’s SODO neighborhood.

Stantec led the design of the project, while Hensel Phelps held the prime contract and was the design-builder on the team. Stantec provided design management; LEED facilitation; electrical engineering; mechanical engineering; site design management; environmental permitting; and design for lighting, IT/communications, security, signals, SCADA, acoustics, and track integration. The project combined Stantec’s global expertise from offices in Seattle, Lynnwood, and Bellevue, Wash.; Vancouver, B.C.; New York, N.Y.; Phoenix, Arizona; Dallas; Atlanta; Las Vegas; and Sacramento, Calif.
