Construction Management is a delivery system where the owner typically contracts separately with the designer and contractor. Unlike a "bid" project where the contractor is hired after designs are completed. The contractor or Construction Manager (CM) is hired in the pre-construction phase and typically provides consulting during the planning and design phases in addition to constructing the project. The CM provides input on costs, constructability and scheduling during design and planning. Once construction starts the CM oversees all costs, scheduling and quality for the project through to completion.
