Wash. Admin. Code § 504-50-032
Procedures must be established for securing telephone, written, or electronic quotations from contractors on the appropriate statewide or WSU established small works rosters to assure that a competitive price is established and to award contracts to the lowest responsible bidder. Detailed plans and specifications are not required as part of the bid invitation. Bids may be solicited from all appropriate contractors on the statewide or WSU established rosters, or, alternatively, if the estimated cost of the work is less than $150,000, the university may direct contract with small businesses as defined by RCW 39.04.010. In the event that the legislature further increases the small business limit, the university is authorized to use small businesses for any projects up to the legislatively authorized limit. Procedures must be established for rotation, notification, and annual publication of small works contracts awarded and contractors contacted for direct negotiation pursuant to RCW 39.04.200.
