ConsensusDocs 482 is a standardized administrative contract document used in design-build project delivery to formally establish that final completion of the construction project has been achieved. This milestone document confirms that all contractual obligations have been fulfilled, that the work conforms to the contract documents, and that the project is free of patent defects.
Final completion is the definitive conclusion of a construction project, and the ConsensusDocs 482 Final Completion Certificate plays a crucial role in clearly documenting this point for both the Design-Builder and the Owner. Once this agreement is signed by both parties, it serves as the formal recognition that the entire scope of work has been successfully completed in accordance with the original design intent and specifications.
One of the key functions of ConsensusDocs 482 is to trigger the release of final retainage. Retainage—typically a small percentage of the contract value—is withheld at various project stages to ensure satisfactory completion of the work. Upon final completion, this document authorizes the release of any remaining withheld funds, completing the financial obligations of the contract.
