RTD, Union Station

This design build project involves the transit improvements at the historic Denver Union Station making it a multi-modal transportation hub. Construction, which began in February 2010, includes: an underground bus terminal, an eight-track commuter rail station, plazas, relocation of the light rail station, and street improvements. This multifaceted project covering 40 acres in Denver’s Central Platte Valley will integrate rail and bus service, along with taxis, bicyclist and pedestrians, into a dynamic urban center.

MEC took part in the relocation of the current light rail station. The track, approximately 4500 linear feet, was reconfigured where there were installations of new ductbank to fit the new additional three relay signal houses, relocated communication house, and relocation of an existing sub-station. This work also included the installation of a 1.5 mile OCS system for the new LRT Platforms. MEC was heavily involved with the tie-in and integration on the modified light rail system.

In addition to the light rail system, MEC is responsible for the electrical portion of the bus terminal and new commuter rail train station. Over 25 miles of various sized conduit and over 70 miles of wire will be installed for the power, fire alarm, lighting and communications systems for the new bus terminal and commuter rail. A lot of coordination will be done to tie-in some of these systems to the local transit agency (RTD) existing systems.
