Learn About Design-Build

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.

Design-Build Projects

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.
