FAR 52.214-10—Contract Award-Sealed Bidding.
Plain-English Summary
FAR 52.214-10 is the standard sealed bidding award provision that tells offerors how the Government will make award under an IFB and what rights the Government reserves during bid evaluation. It covers the no-discussions rule, award to the responsible bidder whose bid is responsive and most advantageous based only on price and price-related factors, the Government’s right to reject any or all bids, accept other than the lowest bid, and waive informalities or minor irregularities, and the ability to award by item or group of items and in quantities less than those offered unless the bidder limits the bid. It also explains when a mailed or otherwise furnished award becomes a binding contract and gives the Government authority to reject materially unbalanced bids as nonresponsive. In practice, this provision is central to sealed bidding because it defines the evaluation framework, protects the integrity of the competitive process, and limits post-bid negotiation. Contractors need to understand that bid responsiveness, pricing structure, and any bid limitations can determine whether they receive award or are rejected, while contracting officers must apply the provision consistently to avoid improper awards or bid protests.
Key Rules
No discussions in sealed bidding
The Government evaluates sealed bids without discussions. Bids are judged as submitted, so bidders generally do not get a chance to revise pricing or correct substantive deficiencies after opening.
Award to responsible responsive bidder
Award goes to the responsible bidder whose bid conforms to the solicitation and is most advantageous to the Government based only on price and the price-related factors stated in the solicitation. This means the award decision is driven by the bid as submitted and the stated evaluation criteria.
Government reservation of rights
The Government may reject any or all bids, accept other than the lowest bid, and waive informalities or minor irregularities. These rights preserve flexibility, but they do not allow the Government to ignore material defects or the stated evaluation scheme.
Partial and reduced-quantity awards
The Government may accept any item or group of items unless the bidder limits the bid, and it may award less than the quantity offered unless the bidder says otherwise. Unless the Schedule says differently, bidders may also offer less than the stated quantity.
Award becomes binding on notice
A written award or acceptance mailed or otherwise furnished to the successful bidder within the bid acceptance period creates a binding contract without further action. The bidder is bound once the Government properly communicates acceptance within the stated time.
Materially unbalanced bids
The Government may reject a bid as nonresponsive if prices are materially unbalanced between line items or subline items. A bid is materially unbalanced when some prices are significantly below cost and others are significantly overstated, creating reasonable doubt that the bid will produce the lowest overall cost or making it effectively an advance payment.
Responsibilities
Contracting Officer
Evaluate sealed bids without discussions, determine responsiveness and responsibility, apply the stated price and price-related evaluation factors, and make award to the proper bidder. The contracting officer must also decide whether to reject all bids, waive only minor irregularities, make item-by-item or partial awards when permitted, and reject materially unbalanced bids when required.
Bidder/Contractor
Submit a complete, responsive bid that conforms to the solicitation, includes any required pricing structure, and remains open for the stated acceptance period. The bidder must understand that bid limitations, qualification language, or unbalanced pricing can reduce award chances or cause rejection.
Agency/Government
Preserve the integrity of the sealed bidding process by evaluating bids only on the solicitation’s stated terms and by documenting decisions to reject, waive, or award. The agency must ensure the solicitation clearly states any price-related factors and any special rules for quantities, items, or bid acceptance.
Practical Implications
Bids are judged exactly as submitted, so even small drafting mistakes can be fatal if they affect responsiveness or create ambiguity.
Contractors should avoid pricing schemes that shift costs heavily between line items, because materially unbalanced pricing can lead to rejection even if the bid appears low overall.
If a bidder wants to limit quantities, items, or award scope, that limitation must be stated clearly; otherwise the Government may award less than the full quantity or any item/group of items.
Contracting officers must distinguish between minor irregularities that can be waived and material defects that cannot, because improper waiver can trigger protests.
The award notice itself matters: once the Government sends a written award or acceptance within the bid acceptance period, the contract is binding without any further signature or negotiation.
Official Regulatory Text
As prescribed in 14.201-6 (e) , insert the following provision: Contract Award-Sealed Bidding (July 1990) (a) The Government will evaluate bids in response to this solicitation without discussions and will award a contract to the responsible bidder whose bid, conforming to the solicitation, will be most advantageous to the Government considering only price and the price-related factors specified elsewhere in the solicitation. (b) The Government may- (1) Reject any or all bids; (2) Accept other than the lowest bid; and (3) Waive informalities or minor irregularities in bids received. (c) The Government may accept any item or group of items of a bid, unless the bidder qualifies the bid by specific limitations. Unless otherwise provided in the Schedule, bids may be submitted for quantities less than those specified. The Government reserves the right to make an award on any item for a quantity less than the quantity offered, at the unit prices offered, unless the bidder specifies otherwise in the bid. (d) A written award or acceptance of a bid mailed or otherwise furnished to the successful bidder within the time for acceptance specified in the bid shall result in a binding contract without further action by either party. (e) The Government may reject a bid as nonresponsive if the prices bid are materially unbalanced between line items or subline items. A bid is materially unbalanced when it is based on prices significantly less than cost for some work and prices which are significantly overstated in relation to cost for other work, and if there is a reasonable doubt that the bid will result in the lowest overall cost to the Government even though it may be the low evaluated bid, or if it is so unbalanced as to be tantamount to allowing an advance payment.
