D.C. Mun. Regs. tit. 27, r. 27-4610
The Contracting Officer may use a variety of methods to publicize procurement. The specific method or methods used should be tailored to the particular procurement, taking into account factors such as the size of the procurement, the type of goods or services sought, the urgency associated with the requirement, and the most efficient means of disseminating information in the relevant market. The methods available to publicize procurement opportunities may include print advertising, Internet notices, developing source lists of qualified firms known to supply particular categories of goods or services, soliciting specific sources through written notices or telephone contacts, and holding pre-bid or pre-proposal conferences.
The Contracting Officer shall use best efforts to provide (either electronically or in paper format) a copy of all solicitations (other than solicitations issued through its small purchase procedures) to CBE firms listed on the Department of Small and Local Business Development's website that may be capable of providing some or all of the services or goods required by a solicitation. The Contracting Officer shall also conduct outreach and provide information to CBEs on at least an annual basis.
In addition to publication or other method of publicizing the procurement opportunity described in subsection 4610.1, unless otherwise specified in this chapter, the Contracting Officer shall also compile a list of at least three (3) vendors that the Contracting Officer reasonably believes are qualified to provide the services or goods specified in a solicitation and shall provide those vendors with a copy of the solicitation. If the Contracting Officer is unable to locate at least three (3) potential vendors, the Contracting Officer shall provide the solicitation to as many vendors as the Contracting Officer can reasonably identify.
