(2) As used in this section:

(a) "Public works" has the same definition as in RCW 39.04.010.

(b) "Riverine project" means a project of construction, alteration, repair, replacement, or improvement other than ordinary maintenance, executed at the cost of the state or of any municipality, or which is by law a lien or charge on any property, carried out on a river or stream and its tributaries and associated floodplains, beds, banks, and waters for the purpose of improving aquatic habitat, improving water quality, restoring floodplain function, or providing flood protection.

(c) "Stormwater project" means a project of construction, alteration, repair, replacement, or improvement other than ordinary maintenance, executed at the cost of the state or of any municipality, or which is by law a lien or charge on any property, carried out on a municipal separate storm sewer system, and any connections to the system, that is regulated under a state-issued national pollutant discharge elimination system general municipal stormwater permit for the purpose of improving control of stormwater runoff quantity and quality from developed land, safely conveying stormwater runoff, or reducing erosion or other water quality impacts caused by municipal separate storm sewer system discharges.

(3) Except as otherwise specified in this chapter or in chapter 36.77 RCW, all counties subject to these provisions shall contract on a competitive basis for all public works 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.

(4) 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 40 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 is sufficient. Such advertisements shall be published at least once at least 13 days prior to the last date upon which bids will be received.

(5) The bids shall be in writing, may be in either hard copy or electronic form as specified by the county, 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.

(6) 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.

(7) If the bidder to whom the contract is awarded fails to enter into the contract and furnish the contractor's bond as required within 10 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. 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. 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.

(8) As limited by subsection (11) of this section, a county subject to these provisions may have public works performed by county employees in any annual or biennial budget period equal to a dollar value not exceeding ten percent of the public works construction budget, including any amount in a supplemental public works construction budget, over the budget period.

Whenever a county subject to these provisions has had public works performed in any budget period up to the maximum permitted amount for that budget period, all remaining public works except emergency work under subsection (13) of this section within that budget period shall be done by contract pursuant to public notice and call for competitive bids as specified in subsection (3) of this section. The state auditor shall report to the state treasurer any county subject to these provisions that exceeds this amount and the extent to which the county has or has not reduced the amount of public works it has performed by public employees in subsequent years.

(9) A county may procure public works with a unit priced contract under this section for the purpose of completing anticipated types of work based on hourly rates or unit pricing for one or more categories of work or trades.

(a) For the purposes of this section, "unit priced contract" means a competitively bid contract in which public works are anticipated on a recurring basis to meet the business or operational needs of the county, under which the contractor agrees to a fixed period indefinite quantity delivery of work, at a defined unit price for each category of work.

(b) Unit priced contracts must be executed for an initial contract term not to exceed one year, with the county having the option of extending or renewing the unit priced contract for one additional year.

(c) Invitations for unit price bids shall include, for purposes of the bid evaluation, estimated quantities of the anticipated types of work or trades, and specify how the county will issue or release work assignments, work orders, or task authorizations pursuant to a unit priced contract for projects, tasks, or other work based on the hourly rates or unit prices bid by the contractor. The contract must be awarded to the lowest responsible bidder as defined under RCW 39.04.010. Whenever possible, the county must invite at least one bid from a certified minority or woman contractor who otherwise qualifies under this section.

(d) Unit price contractors shall pay prevailing wages for all work that would otherwise be subject to the requirements of chapter 39.12 RCW. Prevailing wages for all work performed pursuant to each work order must be the prevailing wage rates in effect at the beginning date for each contract year. Unit priced contracts must have prevailing wage rates updated annually. Intents and affidavits for prevailing wages paid must be submitted annually for all work completed within the previous 12-month period of the unit priced contract.

(10) If a county subject to these provisions has public works performed by public employees in any budget period that are in excess of this ten percent limitation, the amount in excess of the permitted amount shall be reduced from the otherwise permitted amount of public works that may be performed by public employees for that county in its next budget period. Ten percent of the motor vehicle fuel tax distributions to that county shall be withheld if two years after the year in which the excess amount of work occurred, the county has failed to so reduce the amount of public works that it has performed by public employees. The amount withheld shall be distributed to the county when it has demonstrated in its reports to the state auditor that the amount of public works it has performed by public employees has been reduced as required.

(11) In addition to the percentage limitation provided in subsection (8) of this section, counties subject to these provisions containing a population of 400,000 or more shall not have public employees perform: A public works project in excess of $90,000 if more than a single craft or trade is involved with the public works project, a riverine project or stormwater project in excess of $250,000 if more than a single craft or trade is involved with the riverine project or stormwater project, a public works project in excess of $45,000 if only a single craft or trade is involved with the public works project, or a riverine project or stormwater project in excess of $125,000 if only a single craft or trade is involved with the riverine project or stormwater project. A public works project, a riverine project, and a stormwater project means a complete project. The restrictions in this subsection do not permit the division of the project into units of work or classes of work to avoid the restriction on work that may be performed by public employees on a single project.

The cost of a separate public works project shall be the costs of materials, supplies, equipment, and labor on the construction of that project. The value of the public works budget shall be the value of all the separate public works projects within the budget.

(12) In addition to the accounting and recordkeeping requirements contained in chapter 39.04 RCW, any county which uses public employees to perform public works projects under RCW 36.32.240(1) shall prepare a year-end report to be submitted to the state auditor indicating the total dollar amount of the county's public works construction budget and the total dollar amount for public works projects performed by public employees for that year.

The year-end report submitted pursuant to this subsection to the state auditor shall be in accordance with the standard form required by RCW 43.09.205.

(13) Notwithstanding any other provision in this section, counties may use public employees without any limitation for emergency work performed under an emergency declared pursuant to RCW 36.32.270, and any such emergency work shall not be subject to the limitations of this section. Publication of the description and estimate of costs relating to correcting the emergency may be made within seven days after the commencement of the work. Within two weeks of the finding that such an emergency existed, the county legislative authority shall adopt a resolution certifying the damage to public facilities and costs incurred or anticipated relating to correcting the emergency. Additionally this section shall not apply to architectural and engineering or other technical or professional services performed by public employees in connection with a public works project.

(14) In lieu of the procedures of subsections (3) through (12) of this section, a county may let contracts using the small works roster process provided in RCW 39.04.151 through 39.04.154.

Whenever possible, the county shall invite at least one proposal from a certified minority or woman contractor who shall otherwise qualify under this section.

(15) The allocation of public works projects to be performed by county employees shall not be subject to a collective bargaining agreement.

(16) 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.

(17) Nothing in this section prohibits any county from allowing for preferential purchase of products made from recycled materials or products that may be recycled or reused.

(18) This section does not apply to contracts between the public stadium authority and a team affiliate under RCW 36.102.060(4), or development agreements between the public stadium authority and a team affiliate under RCW 36.102.060(7) or leases entered into under RCW 36.102.060(8).
