Public Works and Prevailing Wage.
Public works refer to all work, construction, alteration, repair, or improvement, other than ordinary maintenance, executed at the cost of the state or a municipality. State law requires competitive bidding for all public works projects. Bidders must comply with certain requirements, including maintaining a general construction contractor license and verifying subcontractors maintain required licenses. Contractors may not bid on public works if they have two or more violations of certain licensing or other requirements in the previous five years.
State law requires that prevailing wages be paid to laborers, workers, and mechanics employed in all public works and public building service maintenance contracts. The prevailing wage is established by the industrial statistician at the Department of Labor and Industries (L&I). It is calculated based on the hourly wage, usual benefits, and overtime paid in the largest city in each county, to the majority of workers, laborers, or mechanics in the same trade or occupation. Certain penalties apply to public works contractors who violate provisions requiring the prevailing rate of wage.
Workers who are injured or disabled in the course of employment are entitled to certain benefits through the workers' compensation program, administered by L&I. Benefits may include medical costs, temporary time-loss, vocational rehabilitation benefits, and permanent disabilities benefits.
Types of Contractor Registration and Licenses.
Contractors are required to register with L&I. In addition to registering, contractors must follow requirements relating to advertising, bonds and insurance, and other matters. Some types of work require registering as a general construction contractor, while separate registration and licensing requirements apply to specialty trades. This includes, for example, plumbing contractors, electrical contractors, and elevator contractors.
Certain statutory requirements governing public works, prevailing wage, and workers' compensation apply to general construction contractors, while others make reference to some specialty contractors. Thus, the applicability of those provisions to specialty contractors is inconsistent. In particular, the specialty contractor license for plumbing contractors was established through Senate Bill 6170 (2020), which did not modify the requirements for public works, prevailing wage, and workers' compensation to account for the shift to a specialty license. In effect, certain requirements do not apply to plumbing contractors.
Plumbing Contractors. To perform any plumbing, a contractor must register as a plumbing contractor and have at least one certified plumber as the dedicated plumber for its company. A plumbing contractor may opt to also register as a general construction or specialty contractor in order to perform other types of work, but doing so is not required in order to perform plumbing.
Electrical Contractors. An electrical contractor license is required in order to engage in the business of doing electrical work. Electrical contractors are businesses who engage in the electrical construction business. They must have a certified electrical administrator or a master electrician designated to ensure the business follows applicable laws, rules, and regulations. Electrical contractors employ certified electricians and electrical trainees to perform the work.
Elevator Contractors. Elevator contractors are required to register under the general construction contractor laws, but must obtain an elevator contractor's license in order to employ licensed elevator mechanics and bid on public and private contracts.
Certain public works, prevailing wage, and workers' compensation provisions are modified to include plumbing contractors, and, in some instances, are modified to include electrical and elevator contractors, in order to align those provisions.
The following apply to all types of aforementioned contractors:
