All Aboard for RTD’s West Rail LineContributor: Swinerton Blogger | March 03, 2014
Amid marching bands, choirs, sports team mascots, and local dignitary speeches, on Swinerton celebrated the completion of two design-build parking structures as part of the Regional Transportation District’s (RTD’s) dedication of the West Rail Line, a 12-mile light rail system connecting the western suburbs to downtown Denver’s Union Station. RTD awarded the Wadsworth and Sheridan parking structures as separate design-build projects, though Swinerton teamed with the same architect (Gensler) and engineering firms and many of the same subcontractors on both projects, creating several great advantages to the design and construction.
The Sheridan Parking Structure is a six-level, cast-in-place concrete structure consisting of 817 parking spaces and 262,644 square feet. The original completion date for this project was May 30, 2013, but because this parking structure was the last milestone in the overall West Rail Line project, we committed, and succeeded, in turning over the project to RTD for use on April 26 when the rail line opened.
The Wadsworth Parking Structure is also cast-in-place concrete and consists of four levels to accommodate 1,026 parking spaces over 317,576 square feet. Both structures entail 70-degree diagonal parking in the exterior bays for safety and maximum operational capacity, bicycle parking, low–water-use landscaping, and provisions for future photovoltaic panels and plug-in hybrid electric vehicles.
Disadvantaged and small business enterprise participation was a critical requirement for RTD. We not only met RTD’s prerequisites but exceeded subcontracting goals on both projects: Sheridan achieved 52% SBE participation (against a goal of 51%), and Wadsworth attained 31% DBE participation (against a goal of 16%). During the design phase, Swinerton conducted extensive outreach to the small and disadvantaged business community and hosted informational prebid meetings to build awareness about the projects.
