If your firm is a Prime Contractor that is interested in bidding construction contracts less than $100,000 in value, please visit our Purchasing Department page and register as a New Supplier with IRWD's Purchasing Department.

If your firm is neither a Prime Contractor nor prequalified to be on the Prequalified Contractor List, your firm may still pursue work on IRWD construction projects as a subcontractor as IRWD does not require subcontractor prequalification.
