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. Thus, 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.

To use design-build on a public works project of $5 million or more, an awarding authority (not including the Massachusetts Department of Transportation, the Massachusetts Port Authority (Massport), the Massachusetts Bay Transportation Authority (MBTA) since July 2015 and the Massachusetts Water Resources Authority (MWRA)) must submit an application to the Office of the Inspector General.  The Office has prepared an application form to be completed, pursuant to Chapter 149A. Two copies of the application must be submitted to: Office of the Inspector General, One Ashburton Place, Room 1311, Boston, MA 02108. If you have any questions regarding the application contact Mary Kolesar, Senior Policy Analyst, Policy and Government Division, at (617)722-8809 or mary.kolesar@massmail.state.ma.us.

Since 2005, the OIG has approved five applications to use design-build and issued a "Notice to Proceed to Use Design-Build" letter.  The five projects total approximately $200,649,840 in project costs. Note: The information presented is from the application. Actual project data will vary.
