Contractors Role in Preconstruction Planning

In the construction industry, project success depends on planning in schedule, cost, design, and other deliverables. That planning includes the organization of the resources (people, equipment, and tooling) and costs (materials and labor) to perform at the right time (scheduling).

The goal of preconstruction planning is to standardize the planning process, leading to predictability in resources, costs, and scheduling for each project.  This manual focuses  on the general processes a contractor must perform to implement preconstruction planning and how to manage a designer and the design aspects of the process. Also covered is the use of technology in preconstruction.

This document is free to members in the SMACNA Store.
