Date of Adoption: March 21, 2000.

Purpose: Prevailing wage rates on public work projects are determined and enforced according to the trade or occupation or "classification" of work actually performed. The classifications for over fifty construction occupations presently exist in policy form in documents entitled "Scope of Work Descriptions." The purpose of this rule-making order is to covert those policies into rules (WAC 296-127-01301 through 296-127-01391) and to amend WAC 296-127-013 to reflect the addition of the new scope of work rules. This rule making is also in the spirit of the Governor's Executive Order 97-02 on Regulatory Improvement by incorporating necessary policy into rule.

Citation of Existing Rules Affected by this Order: Amending WAC 296-127-013.

Statutory Authority for Adoption: Chapter 39.12 RCW, RCW 43.22.270, and 43.22.051.

Under RCW 34.05.350 the agency for good cause finds that immediate adoption, amendment, or repeal of a rule is necessary for the preservation of the public health, safety, or general welfare, and that observing the time requirements of notice and opportunity to comment upon adoption of a permanent rule would be contrary to the public interest.

Reasons for this Finding: In order for the Department of Labor and Industries (L&I) to continue to administer and enforce the Prevailing Wage Act, chapter 39.12 RCW, the scope of work descriptions must be immediately converted into rules. For many years, L&I has used the scope of work descriptions, which detail the specific tasks required of fifty-four construction trades, to enforce the statutory mandate that "the prevailing rate of wage shall be the rate of hourly wage, usual benefits and overtime paid in the locality... to the majority of workers, laborers or mechanics, in the same trade or occupation" (RCW 39.12.010). The prevailing wage rates for particular trades correspond with the scope of work descriptions.

These rules arise from a prevailing wage enforcement action entitled In re Anderson & Wood, in which a contractor asserted that the scope of work descriptions were not properly promulgated as rules and, therefore, could not be used to require contractors to pay the corresponding prevailing wage rates. On December 15, 1999, the director of L&I agreed that the scope of work policies should be adopted as rules under the Administrative Procedure Act, chapter 34.05 RCW. Without the use of these scope of work descriptions to define the statutory terms "the same trade or occupation" and to therefore assure that the correct prevailing rate is paid for particular types of tasks, L&I is unable to enforce the prevailing wage laws. Enforcement of the Prevailing Wage Act is essential to protect contractors, workers and the public from economic harm.

The Prevailing Wage Act requires contractors working on government projects to pay employees the prevailing or "market" rate. Using surveys to gather information, L&I establishes prevailing wages county by county for each trade or occupation employed on public works projects. State agencies, counties, municipalities and all political subdivisions of the state award public works contracts.

Contractors rely upon the scope of work descriptions to properly assign prevailing wage rates to the work required to complete their contract with the awarding agency. Prevailing wage disputes are frequently resolved informally simply by bringing the correct scope of work descriptions to the contractor's attention. If the perception exists that the scope of work descriptions are mere suggestions or guidance, rather than binding rules, contractors will lack certainty in bidding on projects and in the wages that they pay their workers.

Without firm scope of work descriptions, uninformed or out-of-area contractors may be tempted to use the uncertainty to their advantage, by submitting bids based on lower wage rates. Because public agencies are required to award contracts to the lowest bidder, responsible local contractors will lose work to contractors planning to pay incorrect prevailing wages. The result will undermine an important purpose of the Prevailing Wage Act, to stabilize and protect local wage standards. See e.g. Everett Concrete v. Department of Labor & Industries, 109 Wn.2d 819 (1988) (Washington State Supreme Court holds that the purpose behind Washington's prevailing wage law is to protect employees of contractors who bid on government work from substandard earnings and to preserve local wage standards).

The harm done to local contractors is real and irreparable. Once a contract is awarded to an out-of-state contractor, who has gained an unfair bidding advantage by deciding to pay a lower prevailing wage than appropriate for the actual work performed on the project, a local firm's opportunity is lost. These outcomes are unfortunate and costly. Enforceable prevailing wages, through use of the scope of work descriptions, are necessary to preserve stability in public work bidding, and to protect Washington contractors from unfair competition.

Washington workers' earnings and opportunities are also harmed by the lack of firm scope of work descriptions. Contractors who ignore prevailing wage requirements can use out-of-area workers willing to work for less than the prevailing wage for their craft, unfairly displacing local tradespeople. Even if local workers are used, an unprincipled contractor may use the uncertainty presently surrounding the scope of work descriptions to pay those workers less than prevailing wages. Such workers may file a complaint with the department and proceeding through the adjudicative process; however, without firm scope of work descriptions, there is a real chance that the workers' claims will not prevail. Even those disputes resolved in the workers' favor will mean the workers will wait years for proper wage payments and will not receive interest.

Prevailing wage surveys and resulting calculations are based on the department's classification plan, which is detailed in the scope of work descriptions. If the wage data reported to the department is based on incorrect worker classifications, the same incorrect information will be used in prevailing wage calculations. The result will be an artificial depression of the prevailing wage levels and a harmful erosion of local wage standards.

Erosion of local wage standards is an economic harm to the general public, as is the unfair competition for general contractors by providing an opportunity for certain contractors to submit low bids, which will supplant local contractors on large government projects. These harms will be avoided by immediate conversion of the scope of work descriptions into rules.
