Which items are included in the contract documents?

• A. The drawings and specifications
• B. The contractor's bids
• C. Advertisement or invitation to bid
• D. The addenda relating to bidding requirements

Answer: (A)

The contract documents are the set of papers that define the work and bind the parties to execute it, with the drawings and the specifications forming the core of that set. The drawings visually convey the design intent, layout, sizes, and relationships of the components, while the specifications spell out materials, workmanship, performance criteria, and quality standards the contractor must meet. Together, they communicate exactly what is to be built and how, providing the basis for bids and for contract administration. Items such as the contractor’s bids and the advertisement or invitation to bid belong to the bidding or procurement process, not the contract documents themselves. Addenda that relate to bidding requirements are likewise part of the bidding package and modify what bidders must submit, rather than being the ongoing contract documents that govern construction. Therefore, the drawings and specifications are the elements included in the contract documents.
