About the research
Construction Manager/General Contractor (CMGC) project delivery is an integrated team approach to the planning, design, and construction of a highway project, to control schedule and budget, and to assure quality for the project owner. The team consists of the owner, the designer, which might be an in-house engineer, and the at-risk construction manager. The aim of this project delivery method is to engage at-risk construction expertise early in the design process to enhance constructability, manage risk, and facilitate concurrent execution of design and construction without the owner giving up control over the details of design as it would in a design-build project. The objective of this research is to address the needs for CMGC guidance for evolving alternative project delivery methods. The research documents the results of a survey of state DOTs (response rate of 84 percent), a content analysis of 50 CMGC solicitation documents, and 10 case studies of CMGC projects. The research yielded a set of CMGC delivery models that are specifically adapted for DOT projects, not a regurgitation of the models in use in vertical construction. The models are described in a Guidebook for initiating and implementing a CMGC project delivery system for highway projects at transportation agencies.
