Section 4.10 - Sub-bidder Categories of Work(1) DCAM shall certify a Sub-bidder in one or more Sub-bidder Categories of Work and shall certify a Sub-bidder in a requested Sub-bidder Category of Work if DCAM's evaluation of the Sub-bidder establishes that the Sub-bidder has the experience and competence to perform such work and the Sub-bidder has met all other requirements for certification.(2)Standard Categories. DCAM shall establish a list of Sub-bidder Categories of Work from among the various trades of work in the building construction industry pursuant to M.G.L. c. 149, § 44F. The Sub-bidder shall identify on the application for certification each Sub-bidder Category of Work for which certification is sought.(3)Special Categories. In the event an Awarding Authority intends to solicit bids for a Building Project requiring sub-bids from Sub-bidders skilled in a unique or specialized class of work not included among the standard Sub-bidder Categories of Work, DCAM may establish a special category of work for such project in consultation with the Awarding Authority. If DCAM establishes a special category of work, then the Awarding Authority shall also establish a schedule that will allow interested Sub-bidders to seek and obtain certification in the special category of work prior to the date of receipt of general bids.
