FAR 14.208—Amendment of invitation for bids.
Plain-English Summary
FAR 14.208 explains how contracting officers must handle changes to an invitation for bids (IFB) before bid opening. It covers amendments for changes in quantity, specifications, delivery schedules, opening dates, and other solicitation terms, as well as corrections to defective or ambiguous IFBs. It also addresses the mechanics of issuing amendments using Standard Form 30, distributing amendments to all firms that received the IFB, posting them in the bid room, and deciding whether the bid opening date must be extended. In addition, it requires the government to treat information given to one prospective bidder as information that may need to be shared with all others when it is necessary for bid preparation or when withholding it would prejudice uninformed bidders. The practical purpose is to preserve full and open competition, ensure all bidders compete on the same information, and reduce the risk of protests, bid mistakes, or award challenges based on unequal access to solicitation information.
Key Rules
Amend all IFB changes
Any change to quantity, specifications, delivery schedule, opening date, or other IFB term must be made by formal amendment. Even if the change was discussed at a pre-bid conference, the contracting officer still must issue an amendment.
Use Standard Form 30
Amendments to an IFB must be issued on Standard Form 30, Amendment of Solicitation/Modification of Contract. This creates a clear written record of the change and ensures the solicitation is officially revised.
Distribute before bid opening
Amendments must be sent to everyone who received the IFB before the time set for bid opening, and they must also be displayed in the bid room. Late distribution can undermine competition and may require postponing opening.
Consider extending bid opening
Before issuing an amendment, the contracting officer must evaluate how much time remains before bid opening and whether bidders need more time to review the change and revise bids. If the amendment is material, an extension may be necessary.
Share bidder-specific information broadly
Any information given to one prospective bidder about the IFB must be furnished promptly to all other prospective bidders as an amendment if it is needed to prepare bids or if failing to share it would prejudice others. This applies even when a pre-bid conference is held.
No award without timely amendment
The government may not award a contract under the IFB unless the amendment containing the information was issued early enough for all prospective bidders to consider it in preparing or modifying bids. This protects fairness and equal competition.
Responsibilities
Contracting Officer
Identify when an IFB must be changed or clarified, issue the amendment on SF 30, decide whether the bid opening date should be extended, and ensure all prospective bidders receive the amendment in time to compete fairly. The contracting officer must also make sure any information provided to one bidder is shared with all others when required.
Agency/Procurement Staff
Support timely preparation, posting, and distribution of amendments, maintain the bid room display, and help ensure the solicitation record reflects all changes and communications.
Prospective Bidders
Monitor the solicitation for amendments, review changes promptly, and adjust bids as needed before opening. Bidders should not rely on pre-bid conference statements alone and should assume only issued amendments control.
Bid Room/Administrative Personnel
Display amendments in the bid room and help ensure that all firms that received the IFB are notified or furnished the amendment before bid opening.
Practical Implications
Pre-bid conference comments do not replace a formal amendment, so contractors should never treat oral statements as binding unless they appear in an issued amendment.
If an amendment is material and there is little time before bid opening, the contracting officer may need to postpone opening to avoid giving some bidders an unfair advantage.
Unequal access to information is a major protest risk; if one bidder gets clarification, the same information usually must go to all bidders.
Bidders should check for amendments right up to bid opening and should be prepared to revise pricing, quantities, delivery commitments, or technical assumptions quickly.
Awarding without a timely amendment can invalidate the competition or lead to a challenged award, so contracting officers must document and distribute changes carefully.
Official Regulatory Text
(a) If it becomes necessary to make changes in quantity, specifications, delivery schedules, opening dates, etc., or to correct a defective or ambiguous invitation, such changes shall be accomplished by amendment of the invitation for bids using Standard Form 30 , Amendment of Solicitation/ Modification of Contract. The fact that a change was mentioned at a pre-bid conference does not relieve the necessity for issuing an amendment. Amendments shall be sent, before the time for bid opening, to everyone to whom invitations have been furnished and shall be displayed in the bid room. (b) Before amending an invitation for bids, the contracting officer shall consider the period of time remaining until bid opening and the need to extend this period. (c) Any information given to a prospective bidder concerning an invitation for bids shall be furnished promptly to all other prospective bidders as an amendment to the invitation (1) if such information is necessary for bidders to submit bids or (2) if the lack of such information would be prejudicial to uninformed bidders. The information shall be furnished even though a pre-bid conference is held. No award shall be made on the invitation unless such amendment has been issued in sufficient time to permit all prospective bidders to consider such information in submitting or modifying their bids.
