FAR and DFARS › FAR Part 14: Sealed Bidding › Subpart 14.2

FAR 14.208 Amendment of invitation for bids.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section explains how changes to an invitation for bids must be made using a formal amendment. It ensures all bidders receive the same information before bid opening, and that any necessary changes are communicated in time for bidders to respond.

Applies to: Contracting officers and prospective bidders on sealed bid acquisitions

What it requires

  • Make changes to an invitation for bids by amendment using Standard Form 30.
  • Send amendments to everyone who received the invitation and display them in the bid room before bid opening.
  • Consider the time remaining until bid opening and whether to extend it before amending.
  • Furnish information given to one prospective bidder to all others as an amendment if it is necessary for bids or if lack of it would be prejudicial.

The 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.
