Unless otherwise required in the Bidding Documents, the Agreement for the Work will be written on which AIA Document?

The correct choice for the Agreement for the Work to be written on, unless specified otherwise in the Bidding Documents, is A101. AIA Document A101 is specifically designed for the standard agreement between the owner and contractor for construction work where the basis of payment is a stipulated sum. This document outlines the essential terms and conditions for the agreement, including the scope of work, contract terms, and payment details, ensuring that both parties have a clear understanding of their responsibilities and expectations throughout the project.

The other choices serve different purposes. A102 is used for agreements where the basis of payment is cost-plus, while A103 is intended for a design-build contract. A104 is utilized for construction contracts based on a guaranteed maximum price. Therefore, these documents are tailored to specific types of projects and payment structures, which is why A101 is the appropriate choice in a general bidding context unless otherwise directed.
