Which three individuals must sign the Certificate of Substantial Completion for it to be valid?

The Certificate of Substantial Completion is an important document in the construction process that signifies that a project has reached a stage where it can be used for its intended purpose, even if some minor work remains to be completed. For this certificate to be valid, it typically requires the signatures of the architect, contractor, and owner.

The architect's signature is crucial as they assess and certify that the project has complied with the design specifications and meets the necessary standards. The contractor signs to confirm that their work is complete according to the contract, signifying that they have fulfilled their obligations regarding the construction. Lastly, the owner’s signature is needed to acknowledge their acceptance of the work completed up to that point and to provide official recognition that the project is substantially complete from their perspective.

This trio of signatures ensures that all involved parties agree on the status of the project, which is essential for the transition to a phase where the owner can take possession and use the facility, even if minor touch-ups and final adjustments are still needed.
