The secretary shall, after consultation with the advisory board, determine the general prevailing minimum wage rate in the locality in which the public work is to be performed for each craft or classification of all workmen needed to perform public work contracts during the anticipated term thereof: Provided, however, That employer and employe contributions for employe benefits pursuant to a bona fide collective bargaining agreement shall be considered an integral part of the wage rate for the purpose of determining the minimum wage rate under this act. Nothing in this act, however, shall prohibit the payment of more than the general prevailing minimum wage rate to any workman employed on public work. The secretary shall forthwith give notice by mail of all determinations of general prevailing minimum wage rates made pursuant to this section to any representative of any craft, any employer or any representative of any group of employers, who shall in writing request the secretary so to do.
