Capitol Rotunda Floor to Receive Additional Support System

Rotunda Floor


PIERRE, S.D. – (DRG News) The Capitol Rotunda floor will soon be the focus of work-as the glass prism floor will be getting an additional support system. The project to reinforce the floor in the more than 100 year old Capitol will start next week and should be complete in early October. Paul Kinsman, Commissioner of the state’s Bureau of Administration says in a press release that the new support system will make sure the floor remains sound for another hundred years. The floor is a combination of Italian terrazzo tile and panels of concrete inset with prism glass cubes. The glass allows light to pass between the first and second floors of the building. When the building was constructed, the concrete in the panels was poured but not reinforced. Modern construction projects utilize steel rebar for reinforcement. Kinsman says thin steel pieces are being added under the concrete panels and support beams to strengthen the floor so it meets modern structural standards. He notes that there will be little change in how the floor looks once the project is complete. While the work is underway, the South Dakota Historical Society Foundation’s gift shop will be closed-at least through mid-September and the display cases with replicas of each of the First Ladies inaugural gowns will be removed. While the new support system is installed, people will still be able to use the first floor hallway and the second floor rotunda will not be affected by the project.
