Staffing needs and utilization for alternative contracting methods in highway design and construction

Purpose This research investigates procedures and effective practices on staffing needs and utilization for successful implementation of alternative contracting methods (ACMs) in the United Sates, including design-build (D-B) and construction manager/general contractor (CM/GC) delivery methods. Design/methodology/approach The review of published empirical studies, a national survey of transportation agencies and case studies of highway agencies form the basis of the conclusions in this research. In addition to the national survey, with 46 of 50 agencies participating, the research presents case studies from five highway agencies in the United States including the following: California, Florida, Georgia, Minnesota and Virginia. These five case studies were selected from agencies that have extensive experience in delivering ACM projects. The case studies involved a thorough procedural review and structured interviews of agency personnel. The agencies then validated the results and conclusions. Findings The results showed that implementing ACM projects requires different knowledge, skills and management and coordination efforts than traditional design-bid-build (D-B-B) projects. The study found that the key success factors of implementing ACMs are the following: (1) establishment of an ACM champion; (2) active involvement of key staff throughout the ACM project development process; (3) appropriate use of consultants and (4) ACM training and staff development. Originality/value This research is the first attempt to examine the staffing needs and utilization for ACM projects.
