With GMP contracts, the general contractor's role is as a construction manager at risk (CMAR). Here, the construction manager is responsible for guiding the project's development stage, consulting the customer on the project design and scope, budget concerns, material suitability and availability, construction challenges and other vital aspects. That allows the contractor to develop an accurate, transparent GMP to which both parties agree. Once the project is underway, the CMAR is the primary touchpoint for project owners, laborers and subcontractors, working to keep costs within the agreed-upon threshold and maintaining high-quality output.
