MACTEC Providing Geotechnical, Environmental Services for Westside Subway Extension Heavy Rail Line and Regional Connector Light Rail Line Projects

LOS ANGELES, March 22, 2011 – MACTEC has been retained as a member of PB Americas team on the Westside Subway Extension project and a member of AECOM/PB Americas team on the Regional Connector Project for the Los Angeles County Metropolitan Transportation Authority (MTA). Allen Kibler, President of MACTEC Engineering and Consulting, Inc., (www.mactec.com), made the announcement.

Under the two separate prime agreements, MACTEC will provide various geotechnical and environmental services for the Westside Subway Extension heavy rail line and Regional Connector light rail line projects. Total combined project fees are over $12 million.

MTA serves as transportation planner and coordinator, designer, builder and operator for one of the country's largest, most populous counties. More than 9.6 million people - nearly one-third of California's residents - live, work, and play within its 1,433-square-mile service area.

MTA plans to construct a new heavy rail passenger line, the $5.1 billion Westside Subway Extension, as a western extension of the existing Metro Purple Line from its western terminus at Wilshire Boulevard and Western Avenue in Los Angeles, to the West Los Angeles Veterans Administration Hospital. The extension is planned to be nine miles long and include seven new stations. Ridership has been projected at 49,000 new station boardings and MTA estimates an additional 27,000 boardings will be generated throughout the Metro system as a result of the subway extension. The project would connect key job centers such as Century City and Westwood with the Metro Rail system. MTA, citing a study by the Los Angeles Economic Development Corporation, said the Westside Subway Extension could create about 40,300 jobs.

The $1.367 billion Regional Connector light rail project is expected to generate 16,000 new system-wide boardings and additional ridership on the connecting light rail lines in Los Angeles County. The regional connector is planned to be almost two miles long and include three new stations. The line would connect major downtown activity centers, connect three existing light rail lines, and reduce transit travel times by 12-20 minutes. MTA said the Regional Connector could generate about 11,400 jobs.

According to MACTEC Senior Vice President/Principal Perry Maljian, G.E., and Chief Engineer/Project Manager Martin B. Hudson, Ph.D., G.E., key tasks include:

  • Geotechnical explorations consisting of:
    • Geophysics
    • Borings
