Presolicitation notices are used by the Government for several reasons, one of which is to aid prospective contractors in submitting proposals without undue expenditure of effort, time, and money. The Government also uses the presolicitation notices to control printing and mailing costs. The presolicitation notice response is used to determine the number of solicitation documents needed and to assure that interested offerors receive the solicitation documents.
