- OWNER: West Dublin / Pleasanton Station Venture, Inc.
- CONTRACT VALUE: $52,000,000
- NTP / START: July 2006
- COMPLETION: April 2011
- WORK DESCRIPTION:
As part of a larger transit village project, this design-build contract provided a new in-fill BART station between the active tracks of the BART mainline and in the median of Interstate 580. The station portion of the project included the design and construction of a 320 ft long, two-level station, concourse, a 700 ft long station platform, and the fabrication and erection of two pedestrian freeway overcrossings. The pedestrian overcrossings link the station to a parking garage on each side of the freeway. Self-performed work included more than 40% of the project work from earthwork, trackwork, third rail traction power, and concrete structures work.
The project required a detailed and phased construction sequence to safely maintain construction at and adjacent to the active BART track and in the median of the heavily traveled highway. During construction, crews accessed the station via the highway shoulder next to the Number One lane of travel. Evening lane closures were used for concrete pours, steel erection of the station building, mobilizing heavy equipment, and installation of the bent structure supporting two pedestrian freeway overcrossings.
The project’s location also required significant design and construction coordination with both BART and Caltrans to ensure that standards and specifications were followed at the interfaces of each agency’s right-of-way. As an example, special provisions were prepared for Caltrans that included qualification, workmanship, and inspection requirements for the HSS Tubular Pratt Through-Truss pedestrian overcrossing structure, since this configuration was not a typical Caltrans standard.
