Keller, Inc. to build for Thermo Fisher scientific/oakbrook Corporation. FITCHBURG, Wis. - Thermo Fisher Scientific, in partnership with Oakbrook Corporation (Property Manager), is moving forward with an addition to expand its loading dock capabilities. The project includes two new loading docks, an improved turning radius, and redesigned traffic flow to better accommodate semi-truck deliveries. The project is being delivered through a design-build partnership with Keller, Inc., an award-winning, 100% employee-owned design-build contractor headquartered in Kaukauna. Thermo Fisher Scientific selected Keller after previous conversations about the design-build process and identified this project as an ideal opportunity to implement the delivery method for the first time. Designed to enhance operational efficiency, the project includes selective demolition of an existing area inside the current loading dock footprint to create a more functional and productive space. Once complete, the improvements will support increased productivity for a growing business unit. Construction is scheduled to begin this summer, with completion anticipated in Fall 2026.
