In an effort to expedite project delivery, TDOT is considering using Accelerated Bridge Construction (ABC) techniques and completing the project under a Construction Manager/General Contractor (CM/GC) contract.

ABC uses innovative planning, design, materials, and construction techniques in a safe and cost-effective manner to reduce the onsite construction time of building, replacing, or rehabilitating bridges. It often uses precast or hybrid cast-in-place bridge elements.

The CM/GC project delivery method involves a contractor in the design and construction phases of the project. The partnership between TDOT, the Designer, and the Contractor reduces risks and improves constructability.

For more information on the CM/GC process for this project, visit the CM/GC SR 1 Project Davidson County information page under the Construction Division section of the TDOT website.
