The use of alternative contracting methods (ACMs) has accelerated the delivery of highway design and construction projects. Led by documented successes on large, high-profile projects such as I-15 in Utah, the Intercounty Connector in Maryland, and the Sellwood Bridge in Oregon, ACMs have resulted in shorter project delivery times with less disruption to the traveling public. The use of ACMs is becoming commonplace in projects by state departments of transportation, but not just for large projects. The information in this document builds on the three-volume NCHRP Research Report 939: Guidebooks for Post-Award Contract Administration for Highway Projects Delivered Using Alternative Contracting Methods.
NCHRP Web-Only Document 421: Agency Implementation of Alternative Contracting Methods, from TRB's National Cooperative Highway Research Program, aims to ensure agencies have the practical methods and tools to improve their ACM contract administration.
