How to Bid to DeMaria

Trade contractors and vendors must be pre-qualified before bidding to and working for DeMaria. Fill out our pre-qualification form here.

DeMaria’s Trade/Vendor Alliance Team manages the prequalification process. Only firms with a positive documented safety history, specific experience, and who consistently perform well will be considered qualified.

Commitment to Minority Trade Contractors

Diversity brings value to the construction process. DeMaria strongly encourages certified minority (MBE), disadvantaged (DBE) and women-owned (WBE) businesses to become prequalified and join us in the pursuit of new construction in Michigan.

Each year, DeMaria hosts a minority subcontractor outreach program designed to discover new talent. We encourage you to attend. It is an excellent forum for networking with DeMaria and learning how to bid on upcoming work. For additional information, please contact Carolyn Pawluchuk, Diversity Manager, at
