Hanson, as a member of a joint venture, prepared final plans and specifications, as well as supporting documents, for the fabrication of the Fox River – Menasha and Upper Appleton Wall repairs in Menasha and Appleton, Wisconsin.
Menasha and Upper Appleton contain dams along the Lower Fox River that include a concrete spillway with ungated and gated sections to control the outflow. The joint-venture team designed repairs addressing the failing walls at both locations.
The Upper Appleton Wall masonry section is more than a century old, with an approximate construction date in 1879. The project team took the structure’s historical nature into consideration when designing repair solutions.
Hanson performed geotechnical services that included a site visit for each location, a review of previous inspection reports and original construction documents, an evaluation of wall stability using assumed parameters from nearby projects and appropriate U.S. Army Corps of Engineers manuals and a review of potential solutions in comparison to anticipated budgets and constructability before moving forward with the recommended repairs.
Hanson also completed the independent technical reviews of the plans; specifications; damage, detection and response; and engineering considerations and instructions for field personnel documentation.
