As part of a joint venture, LAN serves as the GEC for managing the design and construction of DART’s first design-build program—19 miles of light rail infrastructure that connects Dallas/Fort Worth International Airport to downtown Dallas, resulting in a rail network that exceeds 90 miles. The majority of the program consists of a new transit corridor through the City of Irving (Orange Line), and expansion of the Blue Line to the City of Rowlett. The 14-mile Orange Line is a key component of a regional rail expansion that will run parallel with the Green Line through Downtown Dallas to Bachman Station in Northwest Dallas. From Bachman Station, the Orange Line heads northwest to the Las Colinas Urban Center (completed in 2011) and Dallas/Fort Worth International Airport (completed in 2014).

The nearly five-mile DART Rail Blue Line Extension to Rowlett opened in December 2012. The light rail line links Downtown Rowlett and Downtown Garland, both of which are important member cities within the DART System.

The GEC team is responsible for managing the overall design and construction of two design-build teams, one assigned to the Orange Line and the other to the Blue Line Extension. The overall $875 million program has an extremely aggressive schedule with final service to DFW Airport starting in 2014.

GEC responsibilities include the assistance in the preparation of DB bridging documents, assessing DB proposals, reviewing DB design submittals, providing construction management services, and providing overall program QA review, schedule and cost control.
