Accurate 3D Scans Help Gensler Keep Willis Tower Renovation on Schedule During a Pandemic

Problem: While the Willis Tower's architecture was impressive, its interior did not meet the needs of office workers, visitors, or the Chicagoans who do business there daily. One of the most significant obstacles to updating the interior was executing the redevelopment while keeping the building operational for its 15,000 tenants during the unforeseen disruptions of a global pandemic. Gensler Chicago required accurate as-built documentation, an architectural/structural model, and an MEP/FP model on a tight deadline.

Solution: Due to the tower’s vast size and strict timeline, Gensler needed fast, accurate documentation. They partnered with Existing Conditions to 3D laser scan The Willis Tower – streamlining workflows, minimizing costly change orders, and saving critical time.

Benefit: Existing Conditions worked closely with its client to keep their project on schedule, completing it within 90 days. Along with two detailed Revit models, the Mapping & Modeling Team delivered comprehensive floor plans, reflected ceiling plans, and exterior elevations, providing Gensler with an accurate foundation for their design.
