DART Central Business District Project?-?Dallas, Texas
Completed in November 1996, the $58.6 million Dallas Area Rapid Transit (DART) - Central Business District project featured 7,000 feet of light rail track through downtown Dallas. The scope of work involved the relocation of utilities; street and sidewalk reconstruction; installation of approximately 13,000 feet of commuter light-rail track; construction of four passenger stations; traction power; and surface amenities.
Underground utility work was challenging, both in complexity and magnitude. All utilities beneath the new track slab required relocation involving 26-foot-deep cuts throughout a congested downtown area, while continuously monitoring utility routes and relocations. Numerous value engineering concepts and redesigns helped minimize impacts to cost and schedule.
Kiewit also provided design, supply, installation and testing of the communications, central control, and train control systems on various sections of the DART line. To maintain pedestrian and vehicular traffic while relocating utilities, placing rail, and completing surface work, crews developed an easy-to-move barricade system.
