Union Terminal Renovation and Restoration

project at a glance

The original construction of Union Terminal was completed in 1933, and since then the building has served a variety of functions, but most notably it was a train station during the time of WWII. At the peak war time, in 1944, the complex serviced 34,000 people per day.

The structure itself has a massive 180 foot-wide and 106 foot-tall rotunda, which is the second largest half dome in the world after the Sydney Opera House. Union Terminal is labeled as one of the most significant Art Deco buildings in America and is registered as a National Historic Landmark. In 2014, The National Trust for Historic Preservation named Union Terminal 1 of 11 most endangered historic places in the U.S. due to deterioration.

The project consists of a major historical renovation to the interior architecture, complete replacement of the MEP systems, a large site work package, and an extensive exterior renovation and restoration.

One of the project's unique challenges included removing and replacing the original historic limestone, granite, and fountain features to waterproof the roof of the Children's Museum below. Each piece of stone was individually cataloged and inspected for necessary repair.
