Avery Heart Hospital     

Sioux Falls, South Dakota

Investigation to evaluate the causes of and provide repair solutions to the wall cavity condensation and ice formation of this specialty heart hospital. Condensation of the interior humidity resulted from the absence of an effective air barrier in this precast-concrete-clad structure. Repairs required removal of the interior finishes on exterior walls, application of expansive spray foam to function as insulation and an air barrier with special consideration of hidden windows, and reinstallation of the interior finishes.
