By definition, preconstruction is that period before construction starts, often dominated by design development. In this chapter, we will discuss many of the activities that the project manager (PM) and superintendent undertake prior to starting the construction of a project. Some of these tasks may be required by the contract, while others may be voluntarily undertaken as good business practice to help ensure that a successful project is achieved. Preconstruction may therefore be either a formal or informal process as dictated by the construction contract, delivery method chosen by the project owner, and culture of the general contractor (GC). In particular, this chapter focuses on the role of the superintendent during the preconstruction phase.
