What must a Contractor submit to the Architect upon completion?

The correct answer is the Final Application for Payment. This document is essential as it signifies that the contractor is seeking the remaining payment for the work completed on the project. At the conclusion of a construction project, the contractor submits this application to indicate that all work has been finished in accordance with the contract, and it serves as the formal request for the final payment.

Typically, the Final Application for Payment includes a certification that the contractor has fulfilled all contractual obligations and usually accompanies supporting documentation, such as lien waivers and proof of completion of all punch list items. This allows the architect to review and confirm that all aspects of the project have been satisfactorily completed before releasing the final funds to the contractor.

The other options listed do not fulfill this purpose. The Final Certificate of Payment is a document issued by the architect after the Final Application for Payment is reviewed and accepted, confirming that the contractor has met the necessary requirements for final payment. The Initial Project Proposal is a preliminary document outlining the project's goals and budget but does not pertain to completion. Change Orders, while related to modifications during the project, are not submitted at the end, as they are meant to address changes during construction rather than the completion of the existing contract work.
