South Addition and Renovations Project

Glenbard Township High School District 87 is soliciting bids, through construction manager Gilbane Building Company, for the South Addition and Renovations Project, with a virtual pre-bid conference on October 28, 2026 at 11:00 a.m. local time. Bidders must be pre-qualified: bids from firms not pre-qualified under the advertisement will be returned unopened, and current qualifications must be submitted to Gilbane through COMPASS. The project is a public work under the Illinois Prevailing Wage Act, requiring all contractors and subcontractors to comply with prevailing wage requirements, including hourly cash wages plus fringe benefits set by the Illinois Department of Labor.

The scope includes a new main office and entrance addition with a secure vestibule; renovations to life skills and nurse suites, department offices, deans' and counselors' offices, conference rooms, the art room, cafeteria, learning commons, and staff cafeteria; and selective replacement of windows, doors, and exterior stoops. The work is divided into 16 bid packages covering demolition, concrete, masonry, structural steel, carpentry, roofing, glazing, framing, drywall, paint, flooring, food service equipment, site work, paving, and landscaping. Bid security must be a bid bond equal to 10% of the base bid, and no alternative forms are accepted. Performance Bonds and Labor and Material Payment Bonds, each equal to 100% of the bid, may be required from the awarded bidder.

Construction is scheduled to begin in May 2027, with Substantial Completion targeted by August 2028. The project is located in DuPage County, Illinois. Bid documents were distributed on or about October 21, 2026 through Procore Bidding. Site walkthroughs are scheduled for November 2, 2026 at 2:30 p.m. local time, bidder questions are due November 12, 2026 at 5:00 p.m., and proposals are due November 20, 2026 at 9:00 a.m. local time via Procore Bidding.
