Project Overview

NTH was selected by the Michigan Department of Natural Resources (DNR), through the Department of Technology, Management, and Budget (DTMB), to investigate and restore structural issues at the William C. Sterling State Park Headquarters Building in Monroe, Michigan. DNR observed vertical cracking and masonry deterioration on the west wall of the building’s Cold Storage area and sought NTH’s expertise to assess the damage, identify the root cause, and develop repair strategies. The project’s primary goal was to restore structural integrity to the facility, address underlying drainage and foundation issues, and ensure the building’s long-term usability with minimal future maintenance needs.

Project Scope

NTH’s services included an initial site investigation and condition assessment of the Cold Storage and Workshop areas of the Headquarters Building. This involved visually inspecting the extent and severity of vertical cracks and displaced masonry units, reviewing construction drawings, and evaluating site conditions, such as drainage and foundation anchors. Documentation of defects locations and identify potential causes of the observed deterioration.

Based on findings, NTH developed two conceptual restoration alternatives. The first involved replacing the damaged wall with a reinforced CMU wall, while the second proposed a more durable but costlier cast-in-place reinforced concrete wall. Both options incorporated improvements to site drainage by installing gutters, downspouts, and regrading to mitigate water intrusion. NTH also provided detailed cost estimates and design plans for demolition, shoring, and reconstruction. By aligning its services with DNR’s goals, NTH ensured the delivery of feasible, long-term repair solutions within the project’s budget and scope.
