As a subcontractor, we are the lead designer for the Federal Way Link Extension. The 7.8-mile-long design-build project extends light rail south from the Angle Lake Station terminus of the Central Link system at South 200th Street in the city of SeaTac to the Federal Way Transit Center at South 317th Street. The extension travels within the cities of SeaTac, Des Moines, Kent, and Federal Way in King County. The full extension includes three stations.
Sustainability Scope Of Work
The sustainability scope of work includes the application of Envision certification (target: Gold target) for the entire corridor. It also includes LEED-TS certification (target: Silver target) for the Federal Way Transit Center. We also applied LEED-NC certification (target: Silver target) for the End-of-Line facility, and Sound Transit Design Criteria Manual Sustainability checklist for two interim stations.
Our Sustainability team is responsible for guiding the design-build team through the establishment of sustainability objectives, providing technical guidance during the development and implementation of supporting strategies. We kept documentation of all performance with respect to Sound Transit’s contract requirements.
Creating A Sustainability Management Plan For The Federal Way Link Extension
In the early design phase, our team authored the D-B team’s sustainability management plan. We also facilitated an eco-charrette with key stakeholders from the design construction and operational.
