The Dallas Area Rapid Transit (DART) Green Line light rail expansion was named the 2010 Texas Outstanding Civil Engineering Achievement (OCEA) by the American Society of Civil Engineers (ASCE) Texas Section.

The civil engineering projects honored annually with the OCEA award exemplify civil engineering skills and represent a significant contribution to civil engineering progress and society.

STV has worked with DART since the mid-1990s to bring a fast and efficient light rail transit network to the Dallas area. The firm, 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.

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 and was completed in December 2010. The entire second phase covers 46 miles and 26 new stations.

The Texas Section-ASCE is one of the largest and most active sections of the American Society of Civil Engineers. Established in 1913, the Texas Section is headquartered in Austin and comprises 16 branches around the state and student chapters at the state's leading universities.
