Which forms are part of the contract between the Owner and Contractor?

The correct choice identifies A101 - Agreement between Owner and Contractor as a fundamental component of the contractual relationship between the Owner and Contractor. This form outlines the legal agreement that defines the roles, responsibilities, and obligations of both parties in the construction process. It details the scope of work, contract sum, schedule, and payment terms, creating a legally binding framework for the project.

In contrast, a cancellation notice does not form part of the initial contract and only serves to terminate an agreement if needed. Prequalification forms are typically used in the bidding process to assess the capabilities of potential contractors but do not constitute a binding contract. Bid forms may also be part of the proposal process, allowing contractors to submit their offers, but they are not the actual binding agreement between the Owner and Contractor; rather, they are part of the invitation to bid. A101 explicitly serves as the agreement that governs the relationship from start to finish, making it an essential element within the contract documentation.
