Pre-construction services grew out of construction cost estimating to encompass the other activities in planning a project. The intent is to work with the project’s owner to help deliver a satisfactory project that meets the owner’s objectives. In addition to estimating, the preconstruction team participates in design decisions, evaluations, studies, value engineering, value analysis, scheduling, constructability reviews, and more. Design costs, permitting, land acquisition, and life-cycle costs may also be evaluated. In delivering pre-construction services, general contractors or construction managers may also be negotiating for project construction services. Often this may be accomplished by agreeing on a guaranteed maximum price (GMP) for the project. The firm then delivers the project. Typically the owner and the firm share any cost savings realized during construction.
