In Chapter 2, we described several types of project delivery systems that utilised parties specifically vested to act on behalf of the owner in managing the project. When the project manager form is used, this person and their staff become integral members of the team. It is likely that the project manager will be engaged early in the planning process and will serve throughout the project life cycle. Sometimes the party carrying this role is designated as programme manager, the distinction apparently being that the latter has even broader responsibilities. A project manager might be engaged somewhat later in the process, after some of the preliminary planning and feasibility analysis is completed, especially if those early efforts were conducted within the owners organisation. The programme manager will likely act on the owners behalf for the entire project and may serve in this role on multiple simultaneous projects. We should also note that if a construction manager is part of the project team, it is important to add that expertise early in the planning and design phase.
