Contracts & Legalaka: addenda (plural)

Addendum

In Plain English

An official written change to the bid documents issued before bids are due.

Definition

An addendum is a written document issued by the owner or designer before bid submission that modifies, clarifies, or supplements the bid documents. All addenda become part of the contract documents upon execution. Bidders must acknowledge receipt of all addenda in their bid submission or the bid may be rejected as non-responsive.

Example

Addendum No. 2 revised the structural drawings and extended the bid deadline by one week to allow bidders time to reprice.
