How do I read my contractor's construction schedule?
A schedule is a promise with dates attached. Most owners never learn to test whether the promise is real.
Read three things in order: the critical path, the float on everything else, and the long-lead procurement dates. If the critical path is unclear, procurement isn't on the schedule, or every task has zero float, the schedule is a marketing document, not a plan.
The four things that matter
| Term | What it means | Why you care |
|---|---|---|
| Critical path | The chain of tasks that sets the finish date | Only delays here move your completion date |
| Float | Slack a task has before it becomes critical | Zero float everywhere means no room for reality |
| Milestones | Fixed checkpoints: dry-in, power on, C.O. | The dates you can hold a contractor to |
| Long-lead items | Materials ordered months ahead | The most common hidden cause of late projects |
Five schedule red flags
- No procurement or submittal activities shown — only construction tasks
- Every trade appears to work simultaneously with no logic ties
- Updates that move the finish date but never explain why
- Inspection and utility-connection durations of one day each
- A schedule delivered as a PDF picture with no baseline comparison
What to require in your contract
Require a baseline schedule within 30 days of notice to proceed, monthly updates showing actual versus baseline, and written notice of any event that affects the critical path within a set number of days. Tie the monthly pay application to receipt of the schedule update — that single clause does more for schedule discipline than any conversation.
Common questions
- Who owns float in a construction schedule?
- Whoever your contract says owns it — and if the contract is silent, expect a fight. The cleanest language states that float is a shared project resource, available to whichever party needs it first, and not for the exclusive use of the contractor.
