Tornado Recovery in the Heartland
Opened in 1969, the 37-story One Indiana Square is the third tallest building in Indianapolis, Indiana. In 2006 a storm with tornado-level winds damaged 16 stories of the building. While the floors were structurally safe and no one was injured, the winds caused extensive damage to the building’s glass façade.
We provided emergency response, envelope renewal and façade engineering services to Gensler for temporary support and a new curtain wall overclad scheme. We completed the work in 2009.
- After the storm, we helped stabilize the building, evaluated the extent of damage and performed interim repairs.
- Following the response and stabilization phase, we provide design services for the superstructure and new curtain wall system.
- The fast-track, design-build effort involved 3D analysis of the building’s superstructure and foundations, wind tunnel testing for structural and curtain wall loads, the use of Revit to generate the construction documents, and consideration of a liquid tuned-mass damper or other damping systems.
