For construction projects, when must addendums be sent to bidders who have requested specifications?

The requirement to send addendums to bidders who have requested specifications for construction projects is crucial for ensuring that all bidders have equal access to the latest information before they submit their bids. According to New Jersey law, addendums must be communicated no later than 7 days before the bid opening. This timeline allows bidders sufficient time to review the changes and adjust their submissions accordingly, thereby promoting fairness and transparency in the bidding process.

If addendums were sent less than 7 days before the bid opening, it could disadvantage those bidders who might need additional time to understand and incorporate the changes into their proposals. This 7-day advance notice helps in maintaining a level playing field among all participants. The other options do not align with the legal requirements, as they either provide too little time for adequate preparation or suggest communication after the critical bid submission timeframe.
