045-1 Wyo. Code R. § 1-4
Calls for bids on materials and services that are estimated to be above the monetary limits set by statute shall be advertised in the same manner as other work. Bids may be solicited from suppliers without advertising when the estimated cost is below the monetary limits established by statute. A list of bidders supplying materials and services is maintained by the Department. It is segregated by category of materials and services in which the bidder specializes. Prospective bidders will be taken from this list. A potential bidder will be placed on the bidders list by contacting the Department. There is no charge for this service. Bidders will be removed from the list when they do not respond to a request for bid over a period of one year.
