What is the purpose of a specifier's addendum during bidding?

• A. Provides general project background to bidders.
• B. Clarifies or modifies requirements before bid submission, ensuring all bidders have consistent information.
• C. Schedules the project team meetings during bidding.
• D. Lists project risks to be addressed after bids.

Answer: (B)

During bidding, an addendum from the specifier is used to clarify or modify requirements before bid submission, ensuring all bidders have consistent information. It responds to questions, corrects errors, or adds details to the bidding documents, drawings, or specifications so every bid is based on the same scope and data. By updating the documents before bids are due, it preserves fairness and allows accurate comparisons of bids. The other options don’t fit because general background isn’t specific to bid documents, scheduling meetings isn’t the addendum’s purpose, and listing risks to be addressed after bids relates to post-bid planning rather than current bid information.
