Inquiry #1: The DBE goal set by the Department on this Project is unrealistic based on the available DBE capacity in the market. Attempting to reach the goal, if attainable at all, will require significant premium costs to the bids. Please revise the goal to 11% to ensure meaningful DBE participation without causing the Department to pay excessive premium costs.

Inquiry #8: We respectfully request that the bid date be extended a minimum of three weeks. There are currently multiple public works projects bidding, including a large project ($150M) that is scheduled to bid within 1 business day of this project. Prime Contractors and subcontractors will have limited resources to pursue these bid opportunities. A bid extension would allow sufficient time for Prime Contractors and subcontractors to provide complete and competitive estimates for the projects currently advertised.
