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. The Greater Hartford Transit District retained SGH to survey and investigate the brown sandstone facade, recommend appropriate facade restoration approaches, and design and monitor construction of the facade restoration.

Our investigation included the following:

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

We 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 concepts.  DHK architects worked as our subconsultant, evaluating egress and code issues related to the steps and cost estimating.

We subsequently designed and provided construction administration services for the facade restoration.
