The Department of Labor and Workforce Development, Division of Occupational Safety (DOS) issues the rates for each project and determines which rates apply to which classifications (M.G.L. c. 149, s. 26). Prevailing wage rates are set by DOS based upon the rates established in local collective bargaining contracts. DOS also determines whether the prevailing wage applies to a given public works project.

The law requires that contractors post prevailing wage rates in a conspicuous place on all public construction sites. Prevailing wage rates are set for each individual project, and may vary. To obtain a copy of the rates for a particular job, contact the awarding authority and ask for the prevailing wage rate schedule.

Questions about applying the prevailing wage rates should be directed to the Division of Occupational Safety at (617) 727-3492. To submit a prevailing wage request, visit
