Many different methods and formats exist for scheduling construction…from simple sequence-of-activities to sophisticated computer programs with critical path and float times.

A schedule, however, is merely a management tool to assist when planning events.  The schedule alone, being a piece of paper, has no power to control the construction…it is the construction itself that determines whether the project proceeds at a smooth and efficient pace.

If the construction has problems, if the subcontractors do not show up on time or in sufficient numbers, and if materials deliveries are delayed…the schedule merely tells us how far behind the project is in terms of time.
