Build
Once you are certain you have everything in place, you can finally build your dream home. The contractors are required to build your home in accordance with the information in the contract, and an impartial party is meant to confirm that the build is going to plan. In a traditional contract, all communication between you and the construction team will go through your design team or the designated contract administrator. This is usually the architect or the QS in some cases.
Therefore, to start, review your Responsibility Matrix to clarify each Role and Responsibility between you, your Design Team and the Construction Team. This would include:

... And that is it, your home is complete! However, the building contract is not quite complete. You will have a period stipulated in the contract to report any defects to the contract administrator who will instruct the contractor to make good (repair) the defects in a reasonable time. At the end of this period and subject to all repairs being completed, the contract administrator will issue the final certificate bringing the building contract to a close.
