1) Ask for a bill of quantities before signing. Not a per-sqft rate. A BoQ.

2) Ask who the site engineer will be, by name, and get their PEC number.

3) Ask for the last three references — not cherry-picked ones, the last three completed jobs.

4) Ask what their payment milestones look like. Anything front-loaded is a warning.

5) Ask what happens if the schedule slips. Get the answer in writing.

6) Ask what materials brands are baseline vs upgrade. Vague answers = corners being cut.
