Consultant Achievements: DART Green Line extension

STV has worked with Dallas Area Rapid Transit (DART) since the mid-1990s to bring a light rail network to the Dallas area. With two phases now complete, area residents have a fast, efficient light rail system that connects residential and work centers with major community and entertainment destinations.

STV, in a joint venture, provided program management, design and construction management for Phase I of the light rail project - a 25-mile, 13-station light rail build-out of the DART system that was completed in 2003 for $400 million. In total, the joint venture managed 11 major construction packages that ranged in value from $9 million to $50 million. These packages covered the entire infrastructure, bridges, utilities, grade crossings, roadway improvements and park-and-rides. It also covered the expansion of existing maintenance facilities and the construction of a new Northwest Rail Operating Facility.

The first section of the Green Line opened in September 2009, connecting Pearl Station on the east side of Downtown Dallas to MLK Jr. Station on the west side of Fair Park.

STV won first place in the 2003 Engineering Excellence Awards from the Texas Council of Engineering Companies for its work on the first phase.

In addition, STV was part of a four-firm joint venture that was the general engineering consultant for the Green Line in Phase II - a 28-mile, 20-station portion that connects southeast Dallas to the cities of Farmers Branch and Carrollton in the northwest. This segment was completed in December 2010.

The DART Green Line light rail expansion was named the 2010 Texas Outstanding Civil Engineering Achievement by the American Society of Civil Engineers Texas Section.
