Amendments to requests for bids or proposals must be provided to all known recipients of the request for bids or proposals. To assure that the bidder or proposer has received the notice of the change, the procuring agency may require the bidder or proposer to acknowledge receipt of the amendment in the bid or proposal response. If appropriate, an extension of time on requests for bids or proposals will be given to all identified recipients after the amendment is made to the request for bids or proposals.
