The Construction Manager at Risk (CMAR) is a delivery method which entails a commitment by the Construction Manager (CM) to deliver the project within a Guaranteed Maximum Price (GMP) which is based on the construction documents and specifications at the time of the GMP plus any reasonably inferred items or tasks. The CMAR provides professional services and acts as a consultant to the owner in the design development and construction phases. Often times, the CMAR also provides some of the actual construction of the project depending on the availability of bidders and the expertise the company has. In addition to acting in the owner’s interest, the CMAR must manage and control construction costs to not exceed the GMP because contractually any costs exceeding the GMP that are not change orders are the financial liability of the CMAR.
