Bid Responses

The MBTA is bound by Federal and State statutes to publicly advertise all of its construction projects for the solicitation of bids. In order to procure the lowest responsive bidder construction contracts are advertised in various publications and on the MBTA website. For contracts with estimated values exceeding one million dollars, prequalification is required. Prequalification forms can be found on the MBTA Website, or by clicking here.

Once the MBTA receives bid responses from each interested contractor, the bids are reviewed and the initial bid amounts are posted to the website on the date of the bid opening.

Awarded MBTA Contracts

After a thorough review process, the T's primary goal is to ensure that all contracts are awarded to the lowest responsive bidder, within specification requirements and in compliance with MBTA Procurement Policies and Procedures and other Federal and State laws, rules and regulations. Upon execution of the contract, the project advances to the construction phase and overall management of the project is transferred to the construction project manager and his/her field staff.
