Modifies use of cooperative purchasing agreements by certain public contracting units for construction services; prohibits time-and-materials contracts in certain circumstances; allows indefinite delivery, indefinite quantity public contracts in certain circumstances.

This bill modifies how New Jersey public entities (like counties, cities, school districts, and universities) can purchase construction services. It prohibits using "time-and-materials" contracts (where costs are based on hourly labor plus materials) for public works projects covered by prevailing wage laws. Instead, it allows contracting units to use cooperative purchasing agreements for standardized procurement and authorizes "indefinite delivery, indefinite quantity" contracts for goods/services without final project details upfront. All contracts must still comply with public bidding rules and cost-effectiveness reviews before approval.
