Woodies you had a building inspector didn't you? If so, how do they charge? Did they charge per visit & an extra charge to come out & check the items were rectified?
Yes. We had a hump in our slab as well that was picked up at frame stage - definitely not noticeable to the naked eye and it was only when the inspector showed us with his level that we could "see" it. We only got them to come back once though, most of the time we just walked around with our site supervisor and made him show us that everything had been fixed, item by item. Darbecca were great. It was expensive but 100% worth it.
thanks
