CONSTRUCTION MANAGEMENT AT RISK: Why use a construction manager? Major commercial construction projects can be complex with many parts, making it easy for parts of the process to be missed. A construction manager helps lead owners through the difficulties that come with design and construction. In the Construction Management at Risk delivery method, a construction manager is hired early in the process to provide design input as a collaborative team member with the architect/engineer. Advantages to this method include a guaranteed maximum price (GMP) based on the scope of work that is provided by the construction manager early on in the process. The construction manager is responsible for costs in excess of the GMP that are not due to changes in the original scope of work. Also, the design and construction phases can be overlapped to allow for a faster project delivery. The construction manager functions as an objective and experienced representative to the owner of the project in order to ensure the best possible outcome.
