AECOM said it will provide services for the western half of the proposed 15.8-mile route that includes 17 new stations.
Perhaps not coincidentally, the work area does not involve the eastern portion of the proposed LRT route, which has generated some controversy and opposition.
"AECOM is looking forward to being a part of the next step in building an extension of the transit system for the Twin Cities region," said AECOM Chairman and Chief Executive Officer John M. Dionisio in a statement. "We are delighted to play a key role in completing the Southwest Light Rail line as the project will offer a substantial return on investment for transit in the region and provide economic, environmental and social benefits to residents."
Construction is set to begin in 2015, with the line scheduled to begin operating in 2018.
AECOM also designed Met Council's Central Corridor line, now named the Green Line, running mostly through St. Paul and linking up with the existing Hiawatha Line in Minneapolis. The Green Line is set to open in 2014.
Plans also continue for a fourth LRT line serving the Twin Cities, linking Brooklyn Park, Minn. and Minneapolis.
