Learn About Design-Build

Design-build is an alternative construction delivery system that provides responsibility for the delivery of design services and construction services within a single contract.

On a design-build project, the owner selects and executes a single contract with a single entity – e.g., a design-build firm, joint venture, or contractor that subcontracts with a designer – to design and construct the project. Design and construction are combined into a single stage, with no separate bid for construction based on complete plans and specifications. Instead, design-build contracts are procured based on a scope of work statement and performance requirements.

Since 2005, the Office of the Inspector General (OIG) has approved procedures of the exempt agencies. The OIG has also approved six applications from non-exempt agencies to use design-build and issued a "Notice to Proceed to Use Design-Build" letter. This includes the MBTA, which was previously non-exempt.

The six projects total approximately $222,399,840 in project costs.
