Architectural Significance and Design
The Aon Center’s design was influenced by the modernist architectural movement, which emphasized simplicity, functionality, and the use of new materials and technologies. The building’s post-tensioned concrete core and exterior cladding system were innovative features at the time of its construction, allowing for a more efficient and cost-effective building process. The Aon Center’s height and sleek design have made it a notable example of modern skyscraper architecture, and it has been the subject of numerous architectural studies and critiques.
