About the research

Many transportation agencies across the United States currently use the traditional design-bid-build project delivery method as well as other alternative methods, including design-build and construction manager/general contractor (CMGC) to delivery infrastructure to the traveling public. These alternative methods often allow for faster completion of projects. However, there are some challenges associated with these delivery methods as well, including change of roles for transportation agency personnel, differences in procurement processes, and changes in specifications. The Iowa Department of Transportation is interested in learning from the successes and challenges of other transportation agencies to allow for more informed decisions regarding the use of alternative delivery in Iowa. Included in this work is facilitating a peer exchange, documentation of the peer exchange, and cataloging processes and specifications used by other agencies related to alternative delivery methods.
