Interfering Float INTF is defined as the time span in which the completion of an activity may occur and not delay the termination of the project but within which the completion will delay the. length (float) – End to end length of the thread. Free float is how long an activity can be delayed without delaying the Early Start of its successor. This time depend on what tasks are involved. Total Float (TF) = Total Slack = LF – EF = LS – ES = LF – ES – d Another type of float often used in network analysis is the Free Float, which can be calculated as: Free Float = Es (of succeeding activity) – EF (of activity in question) The free float defines the amount of time that an activity can be delayed without taking float away.
