What is a bid bond?

A bid bond, called a bid guarantee in the FAR, is security pledged with your offer that you will sign the contract and furnish the required performance and payment bonds if you win, and failing to include one when required makes a sealed bid nonresponsive.

Also written as: bid guarantee, bid security, what is a bid bond.

FAR 28.001 defines a bid guarantee as a form of security assuring that the bidder will not withdraw a bid within the period specified for acceptance, and will execute a written contract and furnish required bonds within the time specified. FAR 28.101-1 requires one whenever a performance or payment bond is required, unless waived.

It is not a payment. It is a contingent obligation: if you win and then walk away, the government can recover the excess cost of awarding to the next bidder, up to the amount of the guarantee.

The requirement is stated in the solicitation, and in sealed bidding a missing bid guarantee is one of the classic nonresponsive failures. It cannot be supplied after bid opening.

What this means when you bid

If the solicitation requires a bid guarantee, arrange it before the deadline. A bid without it is rejected regardless of price.
