During construction, your builder should strictly adhere to the approved drawings and specifications. Unless there are unforeseen circumstances, changes requested by you, or requirements imposed by building control, the original quoted price should remain fixed.

If any changes are necessary, whether due to unforeseen issues, building control requirements, or your requests, your builder should provide a written estimate of the additional costs or savings involved. You should carefully review these proposals and consult with your Contract Administrator before approving any changes.

It is important to pay for work in arrears. Avoid making upfront payments unless explicitly agreed upon in the contract and agreeable to both parties. Your builder should provide regular valuations of completed work, including any additional costs incurred due to changes or variations. This will allow you to monitor project expenses and prevent surprises at the end of the project.
