The Congestion Avoidance and Reduction for Automobiles and Trucks (CARAT) project was funded by SEP- 14 to evaluate innovative forms of contracting. The CARAT project is a Traffic Management System (TMS) for the Charlotte, NC urban area. The first phase of the TMS (which is approximately 15 miles in length and will include the construction of a Traffic Operations Center) will be constructed using a design- build-warrant contract. With the design-build-warrant contract, one firm will be responsible for finalizing the design, constructing the project, and warranting the system for two years after construction. With the use of design-build-warrant contracting, the North Carolina Department of Transportation was confronted with the issue of how the contractor would be selected. NCDOT, like most other PUB Published by: lic agencies, uses the typical design-bid-build form of project delivery, where the Department signs a contract with the lowest responsible bidder to undertake the construction. Design-build-warrant contracting required the Department to modify its selection and contracting procedures. This paper provides a brief overview of the CARAT project, describes the processes used by NCDOT for the selection of the contractor, and discusses the innovative aspects of this form of contracting. The paper reviews NCDOT'S concerns and how they influenced the selection process, describes the two-step process used in selecting the contractor, and explains the procedures used to evaluate the technical proposals. The pitfalls encountered during the process are presented, along with recommendations other agencies may wish to consider when using design-build-warrant contracting for similar projects. |
