Section 536.270-3 - EvaluationFor sealed bidding that includes options:
(a) The low bidder for purposes of award is the responsible bidder offering the lowest aggregate price for the base bid and all options designated to be evaluated.(b) Before opening bids that include options, the contracting officer must determine, and record in the contract file, the amount of funds available for the project. The amount recorded must be announced at the beginning of the bid opening. This amount may be increased later when determining the items to be awarded to the low bidder if the following condition is met: The award amount of the base bid and evaluated options does not exceed the amount offered for the base bid, the evaluated options, and the same combination of items by any other responsible bidder whose bid conforms to the solicitation. This requirement prevents the displacement of the low bidder by manipulating the options to be used.
