Vendors who are approved by WisDOT to be eli​​gible bidders or plan holders and who want to remain confidential, will not appear on the lists of eligible bidders or plan holders on the HCCI website or Bid Express^tm. It is the responsibility of the vendor to ensure that they have been approved as an eligible bidder before submitting a bid.

Vendors who choose to be confidential are still contractually obligated, as all eligible bidders are, that by submission of the bid, the bidder contractually commits to all applicable laws, regulations and procedures, including any coordination with subcontractors and DBE community.
