The U.S. Department of Transportation, through the John A. Volpe National Transportation Systems Center, is seeking small business contractors for the replacement of four passenger platforms and track repair work at the Lowell National Historical Park in Massachusetts. The project involves comprehensive repairs to the trolley tracks and the replacement of platforms at four designated stations, including the removal of existing structures, ballast replacement, and installation of new platforms and supporting structures. This work is crucial for maintaining the operational integrity of the park's trolley system, which has been in service for 30 years and is reaching the end of its lifecycle for certain components. Interested small businesses are encouraged to RSVP for an Industry Day/Site Visit scheduled for April 30, 2025, and should contact Carl Chin at carl.chin@dot.gov for further details. This notice serves as a market research tool and does not constitute a solicitation for proposals.
