Addenda change drawings, specifications, due dates or answers to bidder questions. Bidders usually acknowledge each addendum on the bid form.
Approved equals from prior-approval requests are often published in an addendum, and named products can change from one addendum to the next.
Why it matters to manufacturers
An addendum can add you to a project or take you off it. Compare each one with the previous version to see what changed.
