Description

The Dunn County Judicial Center is seeking a design-build firm to replace and modernize its HVAC system, focusing on geothermal energy efficiency, reliability, and lifecycle cost savings.

The selected firm will provide a turnkey solution, including design, engineering, procurement, construction, commissioning, and warranty services. The project requires experience in large-scale mechanical, geothermal, and building automation system integration services in occupied government facilities. • The project involves a single design-build entity responsible for all aspects of the project. • The selected firm must have experience in geothermal system installations, major air handling unit replacements, and building automation system upgrades. • The project requires compliance with all Wisconsin and federal construction and procurement laws, including the Davis-Bacon Act. • The contract will be administered by the Dunn County Facilities Department, and the selected firm will be required to provide a single point of contact for all contractual matters.
