The Department of General Services Administration has a requirement for Sioux Falls Courthouse Window Replacement.

This is a window replacement project at the historic Sioux Falls Federal Courthouse in Sioux Falls, SD. The building is a stone clad (local quartzite), concrete and steel framed building. The original building was added onto twice and there have been a variety of remodeling projects over the life of the structure. Built between the 1910s and the early 1930s, the building’s exterior wall features inner wythes of brick and clay tile lath behind the stone veneer and painted plaster or drywall interior finishes, featuring extensive historic wood trim. The original wood windows were partially removed in the 1970s when a more modern aluminum and glass window system was installed.

• The current project is to replace these aluminum windows with aluminum and glass windows that address enhanced energy efficiency and physical security needs. The existing original wood window frame is suspected to exist in many if not most of the openings. It would have been a priority to preserve as much of this original historic fabric as possible during the 1970s window project. It continues to be important to preserve the existing historic material as much as possible. Note some removal of the existing frame will be required to achieve adequate anchorage of the windows to the exterior wall of the building. Protection of the existing interior finishes is of high priority and damage to these finishes during construction shall be restored to pre-construction condition. Work in facility shall correspond in all respects with the existing conditions to which it connects, or to similar existing conditions, in materials, workmanship and finish. Window replacement will have to occur while coordinating with a fully occupied and operational courthouse
