The Northwestern Illinois Building Trades Council encourages the adoption of Responsible Bidder Ordinances to specify certain criteria for contractors who bid on public projects. These ordinances ensure that the safest, most qualified contractors perform the work on behalf of taxpayers, not just the lowest-bidding contractors.

NWIBT also advocates for Prevailing Wage rates on public projects in accordance with The Illinois Prevailing Wage Act (820 ILCS 130), which requires contractors and subcontractors to pay laborers, workers and mechanics employed on public works construction projects no less than the general prevailing wage rates for work performed in the same county.
