Construction Management at Risk (CMAR) is a project delivery method where a construction manager is engaged early in the design process. This manager collaborates with the project team to provide input on cost estimates, scheduling, and construction methods, ensuring that the project stays within budget and on time. In CMAR, the construction manager assumes the risk of delivering the project within a guaranteed maximum price (GMP). This means that if costs exceed the GMP, the construction manager absorbs the additional expenses, incentivizing them to manage resources efficiently and maintain quality throughout the construction process.
