Yes, in competitive acquisitions, the solicitation must notify offerors of your intent. You should either:
(a) Notify offerors that discussions may or may not be held depending on the quality of the proposals received (except clarifications may be used as described in § 636.401). Therefore, the offeror's initial proposal should contain the offeror's best terms from a cost or price and technical standpoint; or
(b) Notify offerors of your intent to establish a competitive range and hold discussions.
