Merging Design Technologies to Fast-Track Transit Project in Fast-Growing Seattle Area

Unique, nontraditional, and highly coordinated BIM process helps Sound Transit’s new Operations and Maintenance Facility take shape

Transit options in large metropolitan areas are in a race to expand to accommodate their growing populations. In the Greater Seattle area, for example, our team is working on a project for Sound Transit that will give momentum to a 25-year, region-wide system expansion program that includes 116 miles of light rail, a new Bus Rapid Transit program, and extended commuter rail service.

Seattle is a gridlocked, growing metropolis—and it’s getting more congested every day. In fact, Seattle has been named the fastest-growing city in the United States this decade, adding more than 114,000 residents since 2010. The Sound Transit Operations and Maintenance Facility (OMF) East will transform transportation services for the Puget Sound area. The light rail vehicle (LRV) fleet will expand from 62 to 184 vehicles, help connect communities, and make work opportunities in and around Seattle more accessible to the local and surrounding communities. So, what’s the secret sauce when taking on a transformative $220 million design-build project? The innovative use of leading-edge digital technology.

When working on a project of this scale, coordinating a wide variety of services and designs onto the build site is no easy task. To help overcome this obstacle, our team used an inventive combination of modeling and design review tools—such as Revit, Civil 3D, Navisworks, iConstruct, and Revizto—in a BIM process in unique and nontraditional ways.
