TRAX Light Rail System
Salt Lake City, Utah
Prior to the start of the 2002 Winter Olympics, construction was completed on the Salt Lake City TRAX, Fast Track Design/Build University Extension Project. This project was a 4.3-mile extension to the original TRAX System, and was designed to provide service to the campus at the University of Utah from the downtown Salt Lake City area.
T-REX (Transportation Expansion Project) Light Rail
Denver, Colo.
Mass. Electric Construction Co. (MEC) was a subcontractor to Kiewit and the scope of work included the install of the traction electrification (17 traction power substations and 19 miles of double-track overhead catenary), signal system, 100 variable message signs, communications system, and a new Operations Control Center tying in the new and existing LRT lines. This new extension was larger than the entire existing LRT system.
Hellgate Line Catenary Modifications
Bronx, N.Y. & Westchester, N.Y.
This project entailed rehabilitation of eight segments of catenary lines from New Rochelle to Sunnyside Yard. The existing systems, which were installed in the 1920s and 1930s, were due for rehabilitation because of age and as a preventative measure to help ensure that the catenary lines would hold in extreme weather events, such as a windstorm.
Tren Urbano-Rio Piedras Rapid Transit System
San Juan, P.R.
As America’s first design-build underground transit project, the Tren Urbano-Rio Piedras rapid transit system involved construction of 10.4 miles of track, a one mile long tunnel and two underground stations for the Puerto Rico Highways and Transportation Authority.
Intercounty Connector Contract B
Montgomery County, Md.
Construction on the eighteen miles of the six-lane, multimodal Intercounty Connector (ICC) variable toll highway began in 2007 and was fully completed in 2014. With the successful completion of similar highway and ITS projects in Colorado, Florida, and Massachusetts, MEC was selected to complete the ICC Contract B (ICCB) segment of the five-phase ICC design-build project.
WMATA Replacement of Traction Power Equipment
Washington, D.C.
This design-build project included the replacement of traction power equipment in thirty-three existing substations and building a training simulator at WMATA’s Telegraph Road facility.
WMATA Rehab Red Line
Washington, D.C.
This project involves the rehabilitation of the District of Columbia’s oldest transit corridor using multiple procurement methods. This best value fixed price project includes design-build bid items, bid-build bid items, and the remainder is JOC (Job Order Contracting) work. The Washington Metropolitan Area Transit Authority (WMATA) Redline Project covers 6-miles of 3rd rail powered double track in a tunnel and on elevated guide-way.
Portland Mall
Portland, Ore.
The Portland Transit Mall project was a 3 mile light rail project located in the center of downtown Portland. As part of Tri-Met’s South Corridor Expansion of an already successful rail network the project will add MAX green line light rail service to the transit mall by connecting the existing green line crossing Steel Bridge and making a loop along 5th and 6th avenues.
Central Artery/Tunnel Electrical Finishes
Boston, Mass.
When it opened in 1959, the original Central Artery comfortably carried about 75,000 vehicles a day. By the late 1980s, it carried upwards of 200,000, making it one of the most congested highways in the United States. This extraordinary traffic mess, often congested for 16 hours per day, represented a continuous economic and quality-of-life drain on Boston and New England.
Miami International Airport Automated People Mover
Miami, Fla.
The MIA Mover, a dual track 1.25-mile long elevated people mover system, connects MIA passengers to the Rental Car Center (RCC) and the Miami Intermodal Center (MIC). The power rail powered Automated People Mover (APM) system is a series of rubber tired driverless vehicles operating on two raised concrete plinths.
