Final answer:
The time period for an architect to approve a contractor's application for payment or withhold payment is typically specified in the contract, often ranging between 7 to 14 days after application receipt.
Step-by-step explanation:
The time period within which an architect must approve a contractor's application for payment or decide to withhold an amount from the certificate for payment is typically defined by the terms of the contract agreed upon between the parties. In general construction contracts, industry practice can vary, but standard terms may require the architect to act within a specified number of days after receipt of the application for payment, often ranging from 7 to 14 days. As each contract may have unique stipulations, always refer to the specific terms outlined within the contract documentation. Failure to adhere to the agreed terms may result in interest charges, disputes, or other contractual complications.
