Green Line Light Rail Expansion

27.7-mile expansion of the DART Green Line Southwest and Northwest Corridors, connecting the heart of Downtown Dallas with the City of Carrollton and southwest Dallas.

Bowman Engineering & Consulting (BEC) performed as part of the Systems Integration Consultant team for the Dallas Area Rapid Transit (DART) Light Rail Build-Out Phase 2. The $1.7B project was completed in December 2010 and added twenty (20) new LRT stations to the existing 45-mile LRT system.  Additionally, the project included approximately 26 miles of double track LRT guideway, bridges, retaining walls, underground structures, utilities, street improvements, as well as at-grade and elevated station platforms, parking lots, landscaping, systems elements, traction electrification, communications, and signals.

Representing DART, BEC provided Construction Contract Administration Services for the $400M Southeast Corridor expansion project and the $470M Northwest Corridor expansion project.

As an integral member of the CMGC Program Management Team, BEC’s responsibilities included contract negotiation, change management, cost and price analysis, cost estimating, risk assessment, pay estimate review, and construction contract administration including the coordination of annual contractor job cost audits to compare actual job costs against the GMP in effort to forecast job cost to complete.

Additionally, BEC was responsible for more than $850M in Guaranteed Maximum Price (GMP) negotiations. As such BEC was directly responsible for review and analysis of contractor packaging strategies, bid tabulations, coordinated audits, labor and burden rate negotiations, equipment ownership and operating rate negotiations.  BEC staff developed and negotiated economic price adjustment clauses for both copper and reinforcing steel and developed negotiation positions and strategies, evaluated cost reduction ideas, and documented the negotiation process.
