GC/CM is a construction project delivery method where the hiring organization consults a general contractor to participate as an advisor during the design process. In this way, the general contractor is seen as a construction manager and works with the architect and engineering firm to ensure constructability of the design and reduce the need for changes during construction. Some “early work” during design may be possible, such as site preparation and purchase of materials (sometimes to take advantage of seasonal prices).
When the project has reached 90% of design, defined as having complete plans and specifications prior to permit review, the GC/CM firm can propose a Maximum Allowable Construction Cost (MACC) and then negotiate a Final Guaranteed Maximum Price (GMP) with the school district.
