(a) The project owner and the prime contractor and all of its subcontractors, regardless of tier, have the absolute right to select any qualified and responsible bidder for the award of contracts on a specified project without reference to the existence or nonexistence of any agreements between such a bidder and any party to such a project labor agreement, and only when such a bidder is willing, ready, and able to become a party to, signs a letter of assent, and complies with such an agreement or agreements, should it be designated the successful bidder; and

(b) It is understood that this is a self-contained, stand-alone agreement, and that by virtue of having become bound to such an agreement or agreements, neither the prime contractor nor the subcontractors are obligated to sign any other local, area, or national agreement.
