A relatively high-level scope of construction work that describes work for 50,000 to 250,000 man hours, depending on the phase of the project. The scope of work described in a CWP contains one discipline and can be broken into multiple IWPs. The contents of a CWP generally include a definition of the work to performed, the Construction Work Area (CWA), key schedule, budget, safety, equipment, materials, craft dependencies, and constraints. In many cases, CWPs are developed in a fashion so contracts can be issued to a specific contractor or contractors.
