What is required before publicly opening bids in New Jersey?

In New Jersey, a resolution approval is a necessary step before publicly opening bids. This resolution is typically adopted by the governing body to formally authorize the bidding process and confirms the terms under which bids will be solicited. It serves as an official record of the decision to seek bids for a particular project and ensures that all procedural requirements are met prior to opening the bids. This process is crucial for maintaining transparency and accountability in public procurement, and it typically includes details such as the project description, funding sources, and timeline.

The other choices, while potentially relevant in specific contexts, do not accurately reflect the procedural requirements before bid openings in New Jersey. For example, an announcement to the public is related to transparency but is not a formal requirement that must occur before bids are opened. Similarly, contractor participation requirements refer to additional considerations related to bidding and contracting but do not constitute a prerequisite for the opening of bids. Approval from the governor is not relevant either, as local bidding processes typically do not require state-level approval. Thus, the focus on resolution approval is why it is the correct choice.
