What is float in a construction schedule?
Last reviewed July 5, 2026
Float is the time a task can be delayed without affecting the project's finish date. It helps you manage scheduling flexibility and resources. Knowing float lets you spot tasks that can be pushed back without causing problems later.
Key points
- Float provides schedule flexibility.
- Helps with resource management.
- Important for spotting potential delays.
In construction, float acts like a buffer. If a task has float, you can shift its start or finish without impacting the project's end date. This is handy when things go wrong, like weather delays or late deliveries. Understanding where float exists helps you prioritise tasks and allocate resources effectively.
