The project required removing five  existing buildings, excavating the new facility’s foundation and shafts, installing initial and permanent rock support, lining the tunnel with concrete, constructing a new ventilation service in the building and reinforcing the loading deck.

Because the site is surrounded by high-rise buildings and busy streets and sidewalks, minimizing the impact to the public presented a challenge. The surrounding buildings were constantly monitored to ensure their integrity was not affected. A temporary roadway deck also was built to facilitate the excavation and construction of the service tunnel connecting to Madison Yards.
