Wash. Rev. Code § 36.32.250
No contract for public works may be entered into by the county legislative authority or by any elected or appointed officer of the county until after bids have been submitted to the county upon specifications therefor. Such specifications shall be in writing and shall be filed with the clerk of the county legislative authority for public inspection. An advertisement shall be published in the county official newspaper stating the time and place where bids will be opened, the time after which bids will not be received, the character of the work to be done, the materials and equipment to be furnished, and that specifications therefor may be seen at the office of the clerk of the county legislative authority. An advertisement shall also be published in a legal newspaper of general circulation in or as near as possible to that part of the county in which such work is to be done. If the county official newspaper is a newspaper of general circulation covering at least forty percent of the residences in that part of the county in which such public works are to be done, then the publication of an advertisement of the applicable specifications in the county official newspaper shall be sufficient. Such advertisements shall be published at least once at least 13 days prior to the last date upon which bids will be received. The bids shall be in writing, shall be filed with the clerk, shall be opened and read in public at the time and place named therefor in the advertisements, and after being opened, shall be filed for public inspection. No bid may be considered for public work unless it is accompanied by a bid deposit in the form of a surety bond, postal money order, cash, cashier's check, or certified check in an amount equal to five percent of the amount of the bid proposed. The contract for the public work shall be awarded to the lowest responsible bidder. Any or all bids may be rejected for good cause. The county legislative authority shall require from the successful bidder for such public work a contractor's bond in the amount and with the conditions imposed by law. If the bidder to whom the contract is awarded fails to enter into the contract and furnish the contractor's bond as required within ten days after notice of the award, exclusive of the day of notice, the amount of the bid deposit shall be forfeited to the county and the contract awarded to the next lowest and best bidder. A low bidder who claims error and fails to enter into a contract is prohibited from bidding on the same project if a second or subsequent call for bids is made for the project. The bid deposit of all unsuccessful bidders shall be returned after the contract is awarded and the required contractor's bond given by the successful bidder is accepted by the county legislative authority. In the letting of any contract for public works involving less than forty thousand dollars, advertisement and competitive bidding may be dispensed with on order of the county legislative authority. Immediately after the award is made, the bid quotations obtained shall be recorded and open to public inspection and shall be available by telephone inquiry.
As an alternative to requirements under this section, a county may let contracts using the small works roster process under RCW 39.04.151 through 39.04.154.
This section does not apply to performance-based contracts, as defined in RCW 39.35A.020(6), that are negotiated under chapter 39.35A RCW.
