DART Green Line (CMGC-1) - Dallas, Texas

As systems subcontractor on this project, Mass. Electric Construction Co. (MEC) worked on DART’s Northwest and Southeast Extensions (CMGC-1 project). The 13-mile long double-track railroad included the Northwest Line Segment 1B and Southeast Line Segments 1 and 2. MEC’s scope of work included the signal system, 23 railroad crossing warnings, the DC Catenary OCS system, installation of owner supplied TPSS, and communication equipment installation.

Throughout the project, MEC participated in regular partnering meetings with the prime contractor, DART. Additionally, because of the project’s excellent performance on cost and schedule, we were able to negotiate a change order to add the Bryan Hawkins Segment. This scope was in excess of $10 million and was completed in time to support DART’s revenue service. The end product was a certified quality project that was completed on time, under budget, with zero accidents, and no regulatory compliance issues.

MEC successfully completed three major systems cutovers into the DART existing rail system at the Bryan-Hawkins interlocking segment, Southeast 1A and 1B segments, and the Northwest line section without interruption to normal revenue service. MEC worked in conjunction with the client’s system start-up team to successfully complete all integrated testing, pre-revenue testing, and commissioning support, allowing for operations to start as scheduled.

MEC achieved a 32% DBE/MBE participation on this project, exceeding the established DBE/MBE goal of 30%. MEC’s approach to maximize participation in the project involved identifying potential contractors and suppliers, reviewing subcontracts, and mentoring their DBE subcontractors to increase their understanding and knowledge of the work and help in their development of work plans.
