My builder has presented me with a quote containing prime cost and provisional sum items. I have now received a MBQ Residential Level 2 contract with (a) Building works component = a positive dollar amount, (b) Total allowances for Prime Cost Items = a positive dollar amount and (c) Total allowances for Provisional Sum Items = $0. From what I understand, the builder has essentially grouped the provisional sum items as a lump sum (aka. fixed price) component in the contract.

I'm assuming that the builder now has enough certainty to make the provisional sums from the quote a fixed price in the contract. Of course this is something I'll need to confirm with the builder.

However, I'm interested in hearing if others have had a similar experience where their builders have made the provisional sums fixed in their contract.
