Section 12:64-2.2 - Multiple classes of work

(a) Where, during a given workweek, a worker performs work in multiple job classifications and two or more "prevailing wages for building services" are applicable to the separate classes of work performed, the contractor must pay the worker the highest of such "prevailing wages for building services" for all hours worked in the workweek, unless the contractor's records clearly delineate which hours of work for the given worker in the given workweek were spent engaged in each separate class of work.

(b) Where a worker is employed or engaged for a portion of a given workweek in work not subject to the Act, which work would otherwise be compensated at a rate lower than the "prevailing wage for building services" to which a worker is entitled for covered work performed during the workweek, the contractor must pay the worker the higher "prevailing wage for building services" for all work performed during the workweek, including work not subject to the Act, unless the contractor's records clearly delineate which hours of work for the given worker in the given workweek were spent engaged in covered work and which hours were spent engaged in work not subject to the Act.
