  Please join APT WGLC on Wednesday, May 28th, for a virtual tour of the Washington County Historic Courthouse! The live virtual presentation and tour will be presented by Elizabeth Manning, PhD, PE (MN) and Sean Cotton, PE (MN, MD, MS, NJ, TX).

  Washington County Historic Courthouse Emergency Stabilization and Structural Repairs
  

  The Washington County Historic Courthouse in Stillwater, Minnesota was constructed between 1867 and 1870 and served as a courthouse and jail for many years. In 1971 it was entered onto the National Register of Historic Places. Today Washington County operates the site as a county park and historic site.

  During a condition assessment to determine the scope of work for an exterior rehabilitation project, significant deflection of the courtroom ceiling was observed. When insulation was removed for further observations, a fracture through the bottom chord of one of the four timber roof trusses was discovered. The courthouse was closed to the public until an emergency stabilization could be completed.

  This live virtual presentation and tour will share the story of this emergency structural stabilization, the investigations leading up to it, the results of the structural analysis of the full roof truss system, and the final repairs completed in spring of 2024. The virtual tour will take you from the exterior of the building through the courtroom and up to the attic where the truss repairs can be seen up close. This exclusive virtual tour would not be possible in person, since there is no public access to the attic spaces.
