Installation of a Concrete Slab with Boiler and Radiant Heat and Solar Array for a New Greenhouse

College of DuPage in Dupage County, Illinois is soliciting bids for installation of a concrete slab with boiler, radiant heat system, and solar photovoltaic array for a new greenhouse facility, with proposals due August 26, 2026.

The scope encompasses site preparation, design, material procurement, installation, testing, and commissioning of a reinforced concrete foundation slab, hydronic heating system with boiler and radiant tubing, and rooftop solar array. The concrete work must meet specified strength ratings and proper drainage slope. The radiant heating system must be designed for greenhouse climate control with integrated controls. The solar array must comply with electrical codes and be sized to offset a portion of the facility's operational energy consumption. All work must coordinate with existing campus utilities and infrastructure, obtain necessary permits, and comply with Illinois building codes and College of DuPage standards. Contractors must demonstrate experience with similar greenhouse construction projects and integrated renewable energy installations.

No contract value, set-aside, preference program, incumbent contractor, specific evaluation criteria, pre-bid or site-visit date, or question deadline is identified in the source materials.
