Ask who your point of contact will be during construction, and how often you will hear from them.
Ask what is genuinely included in the price, and what commonly gets added later as a variation.
Ask how site conditions are assessed before contract, and how a soil or wind classification change is handled.
Ask how quality is checked at each stage, and who signs off on it.
Ask to see current and completed work. What a builder is happy to show you tells you a great deal.
