Picture managing the full renovation of the Willis Tower, one of Chicago's most iconic skyscrapers, while preserving its architectural integrity and bringing modernity. For architects, navigating such a complex project requires accurate, reliable documentation to ensure smooth workflows and minimize costly risks. In this interactive session, we'll explore how cutting-edge technologies like 3D laser scanning, point clouds, CAD, and BIM can streamline how you approach architectural renovations. We'll dive into real-world examples, such as the Willis Tower renovation by Gensler, where nearly 2,000 scans were performed with minimal disruption to daily operations. The session will focus on how to integrate safety and efficiency in your own projects using modern digital tools. We'll address common questions and misconceptions related to the use of 3D laser scanning and BIM, while also providing a deep dive into the value of these resources.
