Work will begin soon to provide extra support for a floor in the South Dakota Capitol that features glass cubes.
The work should be completed in early October.
The floor is a combination of tile and panels of concrete inset with glass prism cubes that allow light to pass between the Capitol's first floor and the second-floor rotunda.
State Bureau of Administration Commissioner Paul Kinsman says the work on the 100-year-old Capitol will make sure the floor remains sound for another century.
Kinsman says when the Capitol was built, the concrete in the panels was not reinforced with steel as is done in modern construction. He says thin steel pieces are being added under the concrete panels and support beams to strengthen the floor
