Free float is the amount of time a task can be delayed without affecting the project's critical path. Total float is the total amount of time a task can be delayed without delaying the project's completion.

• Free float is specific to an individual task, while total float is applicable to the entire project.

• Free float is calculated by subtracting the early start date of a task from the early finish date of its successor task.

• Total float is calculated by subtracting the early sta...read more

Supportive instruments for piping include pipe hangers, clamps, supports, and anchors.

• Pipe hangers are used to support the weight of the pipe and its contents.

• Clamps are used to hold pipes in place and prevent movement.

• Supports are used to provide additional stability and prevent sagging or bending.

• Anchors are used to secure the pipe in place and prevent it from shifting.

• Examples include beam clamps, clevis hangers, riser clamps, and sway braces.
