Iowa City, Iowa - Iowa State Capitol Dome Restoration
TDTW designed, cut and installed a 20 foot wide by 20 foot long by 16 foot tall bell tower and a 16 foot tall octagonal cupola to support the dome on the Old Capitol Building. We utilized select structural white oak timbers for this project. These two structures were built with heavy timbers and hidden steel knife plates. The bell tower was lifted to a height of 80 feet and the cupola rested atop the bell tower. This project required extensive use of tension rods and metal connectors.
