(b) The contracting officer must establish a solicitation response time that will afford potential offerors a reasonable opportunity to respond to each proposed contract action, (including actions where the notice of proposed contract action and solicitation information is accessible through the GPE), in an amount estimated to be greater than $25,000, but not greater than the simplified acquisition threshold; or each contract action for the acquisition of commercial items in an amount estimated to be greater than $25,000. The contracting officer should consider the circumstances of the individual acquisition, such as the complexity, commerciality, availability, and urgency, when establishing the solicitation response time.
