This is a pre-bid meeting notification document for Winnebago County, Wisconsin's Wittman Airport Control Tower Chiller Replacement project. The document specifies that Winnebago County staff will be present at Gate #33 to admit attendees to the mandatory pre-bid meeting scheduled for November 18, 2025, at 10:00 am. The project requires contractors to provide all labor, equipment, and materials necessary to remove the existing chiller (CH-1) and install a new chiller (CH-001) with a 33.3 kW capacity and four compressors, including electrical and mechanical system modifications integrated with existing airport infrastructure in rooms 110, 111, and 114 of the control tower. Sealed bids are due December 2, 2025, at 3:00 pm Central Time through the County's OpenGov Procurement portal.

Contractors must submit a bid bond equal to 5% of the total bid amount, maintain bid validity for 60 calendar days, and provide a Certificate of Insurance along with a Public Improvement Performance/Labor and Material Payment Bond. Required insurance coverage includes Workers' Compensation ($100,000 per accident), Commercial General Liability ($1,000,000 per occurrence), and Automobile Liability ($1,000,000 per occurrence). No specific budget is disclosed, though the detailed technical specifications suggest a significant infrastructure investment. The county will retain 5% from each partial payment until 50% project completion, and invoices will be processed net 30 with Winnebago County's tax-exempt status applying to material purchases. No incumbent vendors are identified, and the procurement does not explicitly indicate set-aside designations for disadvantaged enterprises.
