48 CFR § 36.211 - Distribution of advance notices and solicitations.
Advance notices and solicitations should be distributed to reach as many prospective offerors as practicable. Contracting officers may send notices and solicitations to organizations that maintain, without charge to the public, display rooms for the benefit of prospective offerors, subcontractors, and material suppliers. If requested by such organizations, this may be done for all or a stated class of construction projects on an annual or semiannual basis. Contracting officers may determine the geographical extent of distribution of advance notices and solicitations on a case-by-case basis.
