Union Station Facade Repairs


Union Station is listed on the National Register of Historic Places and is an important part of the architectural heritage of downtown Hartford. Originally constructed in 1889, the building was significantly damaged in a fire in 1914 and was rebuilt with the addition of a second story to the center portion of the building. The station, designed in the Richardsonian Romanesque style with brownstone (brown sandstone) facades, supports major train lines and bus service. SGH surveyed the brown sandstone facades and investigated the condition of the clay tile, copper sheet, and membrane roofs.

Our investigation included the following:

  • A combination of binocular and hands-on surveys of the entire masonry facade and roofing systems
  • Observations of concealed conditions at exploratory masonry and roofing openings
  • Testing and analysis of stone and mortar samples in our in-house laboratory

SGH prepared a detailed report describing the existing conditions, laboratory testing results, and our recommendations for short-term and long-term repairs, with sketches of key repair masonry concepts. We provided a separate report describing our observations of the existing conditions and options for roofing repairs/replacement.

We subsequently designed and provided construction administration services for repairs to the brownstone facades and clay tile roofs along with replacement of the copper sheet and membrane roofs.
