AACE Seattle Section Webinar – June 11th, 2020

TITLE: Completing the Bellevue Downtown Tunnel On Time and Under Budget, Challenges and Success Stories!

SYNOPSIS: The Downtown Bellevue Tunnel (DBT) is part of Sound Transit’s $3.7 billion East Link Extension Program, a 14-mile extension of the Sound Transit (ST) light rail transit system from downtown Seattle, across a floating bridge over Lake Washington, to the cities of Mercer Island, Bellevue, and Redmond. The DBT project consists of a 250-foot-long cut-and-cover portal structure at the southern end, a 1,983-foot-long Soft Ground Sequential Excavation Method (SEM) tunnel, and a mid-tunnel access shaft with a short adit connecting it to the tunnel.

This presentation will provide an overview of the SEM tunnel and the steps how the project team, lead by McMillen Jacobs Associates was able to complete this high profile project on time and under budget.
