045-18 Wyo. Code R. § 18-4
A consultant shall be selected for a particular project using procedures specified in WYDOT operating policies. For large projects, this process shall involve a selection committee evaluating several firms or individuals predetermined to meet the minimum qualifications. For small projects, the consultant may be selected less formally, though the basis for selection shall be documented. Under the following circumstances, as determined by the applicable Department division administrator, a noncompetitive selection may be made:
(a) The service is available only from a single source;
(b) An emergency precludes conducting a competitive selection; or
(c) After solicitation, the number of sources responding is found inadequate.
