The Elizabeth River Tunnels Public-Private Partnership (P3) project is underway in the cities of Norfolk and Portsmouth, Virginia. MEC’s work includes construction and pre-construction services for electrical systems for the new Midtown Tunnel and Martin Luther King Expressway, and rehabilitation of the existing Downtown and Midtown Tunnels. Through 2018, MEC will be working with SKW Constructors, a Skanska, Kiewit, Weeks Marine Joint Venture.
As the signature of Boston’s Big Dig project, the Leonard P. Zakim/Bunker Hill Bridge (Zakim Bridge), completed in 2002 and fully opened in 2004 is not only the world’s widest asymmetrical cable-stayed bridge, but it is also the first asymmetrical cable-stayed bridge in the nation. The bridge, which spans from Boston’s North End to Charlestown, MA, consists of ten lanes, and merges I-93 and U.S. Route 1 traffic across the Charles River, into and out of the Thomas P. O’Neill Jr. Tunnel.
The El Pico Surface Water Treatment Plant (SWTP) is a new 20MDG surface water treatment plant which extracts water from the Rio Grande River, and distributes the potable water to the City of Laredo, Texas. The plant has been engineered with an expandable infrastructure to eventually support up to an 80MGD capacity. Work began on the new plant in December 2011 and was completed in December 2013.
Mass. Electric Construction Co. (MEC), working as the prime electrical subcontractor with a team of six other contractors, worked on the construction of the new 116MW Thomas A. Watson Generating Station located in Braintree, MA. Construction began on the project in April 2008. The project consisted of the installation of two new 50MW, gas turbine Rolls Royce Generators, connected to two new, 70MVA transformers (GSU’s), which feed the grid at 115KV.
The goal of the Central Artery/Tunnel project, more commonly know as the “Big Dig”, was to replace the six-lane elevated highway with an eight-to-ten-lane underground expressway directly beneath the existing road, culminating at its northern limit in a 14-lane, two-bridge crossing of the Charles River. After the underground highway opened to traffic, the crumbling elevated highway was demolished and in its place is open space.
MEC managed crews on electrical installations at the Iatan Coal-Fired Power Plant. Crews constructed and installed the Air Quality Control System (back-end or AQCS) for the existing 651 MW Unit I plant, and worked on the construction of major components for a new, 850 MW Unit II, including the Steam Turbine, Boiler, AQCS, and balance of plant (BOP) electrical work.
In February 2012, Mass. Electric Construction Co. began the replacement of the electrical distribution feeding the Farley and Pavilion Buildings at Children’s Hospital Medical Center (CHMC) in Boston, Mass. The project was required to increase the efficiency of the system and addressed updates to electrical code.
