The project team built a new steel frame to hold an independent glass wall system around one of Indianapolis’ most recognizable buildings, replacing a surface damaged by storm winds. Crews created an innovative construction technique to install the new face.

Once the exterior glass wall was complete, the contractor demolished and removed the old exterior from the inside with minimal disruption to tenants.

The One Indiana Square Project had several unique and challenging aspects during both design and construction of the project.

The most significant challenge was developing an overclad design that provided a new, high performance curtainwall system that could be completed over the current building enclosure.

The goal of the project was to provide a new curtainwall system with its support frame connected to and supported by the existing building structure, but not disrupt the building’s tenants to make these connections.

The project contractor worked closely with the architect, structural engineer and curtainwall consultant to develop the final product.
