Which of the following is NOT true about Addenda?

• A. Usually issued prior to receiving bids.
• B. Clarifies questions raised by bidders.
• C. Involves post-bid adjustments to the contract sum.
• D. May delete information in the procurement documents.

Answer: (C)

Addenda are issued to the bidding documents before bids are submitted to clarify questions and modify the documents as needed, ensuring all bidders base proposals on the same information. They may address bidder questions, add or delete information, and update requirements in the procurement documents. What they do not do is post-bid adjustments to the contract sum; changes to the contract sum after bids are opened and the contract is awarded are handled later through change orders or contract amendments during construction, not by addenda.
