In the context of construction projects, the term "float" usually refers to the amount of time that an activity can be delayed without impacting subsequent activities and/or the contractual completion date. In essence, it is a time contingency that is built into the programme to allow for unforeseen issues.

There are several types of float, including the following:

  • Total float: The length of time that an activity may be delayed without delaying the contractual completion date/impacting the critical path.
  • Free float (or activity float): The length of time that an activity can be delayed without impacting activities that immediately follow.
  • Terminal float: The length of time between the contractor's planned completion date and the contractual completion date.
