Illinois Prevailing Wage Act

For all contracts classified as “construction” or “public works,” as defined in the Illinois Prevailing Wage Act (820 ILCS 130/0.01 et seq.) (the “Act”), the Contractor shall pay no less than the prevailing rate of wages as determined by the Illinois Department of Labor to all workers, mechanics, laborers, and others employed on the project. 

The Illinois Department of Labor periodically revises the prevailing wage rates for the various trades. Current prevailing wage rates are available on the Illinois Department of Labor’s official website. 

The Contractor shall timely submit certified payroll records and all other information required by the Prevailing Wage Act through the Illinois Department of Labor’s Prevailing Wage Portal and shall fully comply with all requirements of the Act.

Approved Joint Purchasing Contracts

The DuPage Airport Authority may make purchases through contracts awarded by joint purchasing alliances of which the Authority is a member, or becomes a member, provided the contracts were formally competed by the alliance or participating governmental entity, including, without limitation, DuPage County. 

Use of contracts approved by a joint purchasing agency or a governmental agency participating in the joint purchasing alliance (for example, contracts approved by DuPage County) is permitted but not required. 

The DuPage Airport Authority currently recognizes the following joint purchasing contracts: 

• General Services Administration (GSA) 
• Sourcewell 
• OMNIA Partners 
• State of Illinois 

Why the DuPage Airport Authority Uses Joint Purchasing Agreements 

To ensure responsible stewardship of taxpayer dollars, the DuPage Airport Authority Procurement Department evaluates the use of joint purchasing agreements when appropriate. These agreements allow the Authority to benefit from competitively awarded contracts established through collaborative purchasing efforts. 

The Procurement Department may utilize joint purchasing agreements in the following circumstances: 

• Cost Effectiveness: When market research demonstrates that the economies of scale provided through a joint purchasing agreement offer the most cost-effective procurement option. 
• Time Efficiency: When project timelines are critical, joint purchasing agreements can reduce acquisition time by a minimum of 30 days compared to issuing a formal Invitation to Bid. 
• Best Value: When re-bidding through the Authority’s Procurement Services is unlikely to result in additional value or cost savings. 

The Procurement Department only utilizes joint purchasing agreements that meet or exceed all applicable state and local government procurement requirements.

Responsibility of Bidders or Offerors

For contracts classified as “construction” or “public works” under the Prevailing Wage Act (820 ILCS 130/1 et seq.), all Bidders or Offerors must comply with DuPage Airport Authority Procurement Code Section 6-26, Responsibility of Bidders. 

The bidder and all bidder’s sub-contractors must participate in active apprenticeship and training programs approved and registered with the U.S. Department of Labor’s Office of Apprenticeship for each of the trades of work contemplated under the awarded contract. 

The bidder and bidder’s sub-contractors must provide document(s) of journey level certification applicable to the work to be performed by each trade performing work on the project including one (1) of the following: (a) a journeyman card issued by the U.S. Department of Labor, (b) an applicable trade license issued by State or local licensing board which requires competency testing to obtain the license, or (c) journey-level competency verified by the National Center for Construction Education and Research (NCCER) National Craft Assessment and Certification Program or other agency approved by the United States Department of Labor.  Each contractor self-performing work and each subcontractor shall require at least one journey-level worker to be present at the work site at all times when work is performed.
