What can happen if the Architect and Contractor disagree about the Application for Payment?

When the Architect and Contractor disagree about the Application for Payment, it is within the Architect's authority to issue a certificate for a different amount than what the Contractor has submitted. This option recognizes the Architect's role in the construction process as an impartial mediator. The Architect reviews the Application for Payment based on the work completed, compliance with the contract documents, and other relevant factors. If the Architect finds discrepancies or believes the amount requested is not justified, they can adjust the payment amount accordingly and certify the reduced amount for payment. This process helps ensure that payments made are in line with the actual progress and quality of work completed, while also maintaining the project's cash flow and accountability.

The other choices do not reflect the usual procedures in such situations. The Owner's involvement in directly resolving disputes is not automatic and typically occurs later if matters cannot be reconciled. Mediation sessions might be necessary, but it's not a standard practice initiated by the Architect in this scenario. Additionally, stopping work would not be an immediate result of a disagreement over payment applications; the Contractor may choose to negotiate or resolve the difference before considering such actions.
