Addenda serve to do what?

• A. Written or graphic instruction to clarify, revise, add to, or delete information in the procurement documents, usually prior to receiving bids.
• B. A formal contract amendment after award.
• C. A field directive with no changes.
• D. A list of approved suppliers.

Answer: (A)

Addenda are written or graphic instructions issued during the bidding phase to clarify or modify the procurement documents. They can add detail, revise requirements, or delete information so all bidders have a consistent, updated understanding before submitting bids. These documents typically arrive before bid openings and become part of the contract documents, ensuring uniform interpretation and preventing later disputes.

This isn’t about changes after a contract is awarded (that would be a contract amendment), nor about site field directives that don’t alter the procurement paperwork, nor about listing approved suppliers.
