b. With regard to the branch work categories in subsection a. of this section, the contracting agent shall advertise for and receive in the manner provided by law (1) separate bids for each of the foregoing categories (a) through (e), or (2) single bids by general contractors for all work and materials required to complete the entire project, if awarded as a single contract, or (3) both.In the case of separate bids under paragraph (1) or (3) of this subsection for categories (a) through (d) of subsection a. of this section, prime contractors shall not be required to name subcontractors in their bid. In the case of a single bid under paragraph (2) or (3), all bids submitted shall set forth the name or names of, and evidence of performance security from, all subcontractors to whom the general contractor will subcontract the work described in the foregoing categories (a) through (d) of subsection a. of this section. Subcontractors who furnish non-specialty trade work pursuant to category (e) or subcontractors who furnish work to named subcontractors pursuant to categories (a) through (d) shall not be named in the bid. Notwithstanding the foregoing provisions of this subsection, a county college may choose to require in its bid specification that a subcontractor shall be named in a bid when, in the case of paragraph (1) of subsection b. of this section, separate bids for each category, the work of that subcontractor exceeds 35 percent of the county college's estimated amount of value of the work, which shall be set forth in the bid specification.

c. Contracts shall be awarded to the lowest responsible bidder. In the event that a contract is advertised in accordance with (3) above, the contract shall be awarded in the following manner: if the sum total of the amounts bid by the lowest responsible bidder for each category (a) through (e) is less than the amount bid by the lowest responsible bidder for all the work and materials, the county college shall award separate contracts for each of such categories to the lowest responsible bidder therefor, but if the sum total of the amount bid by the lowest responsible bidder for each category is not less than the amount bid by the lowest responsible bidder for all the work and materials, the county college shall award a single contract to the lowest responsible bidder for all of such work and materials. In every case in which a contract is awarded under (2) above, all payments required to be made under the contract for work and materials supplied by a subcontractor shall, upon the certification of the contractor of the amount due to the subcontractor, be paid directly to the subcontractor.
