Seismic Retrofit & BIM Integration for Heritage Tower

A landmark 1920s commercial tower required a comprehensive structural upgrade to meet modern seismic codes without compromising its historic facade. Our team delivered a full-scale retrofit using advanced BIM modeling to coordinate new steel reinforcement within the existing masonry shell.

The Challenge

The building's original unreinforced masonry structure posed a significant collapse risk in a seismic event. The project demanded a solution that preserved architectural heritage, minimized tenant disruption, and adhered to a strict municipal preservation timeline.

Our Solution

We developed a hybrid structural system. A concealed internal steel moment frame was designed using detailed 3D BIM models, which allowed for precise fabrication and installation sequencing. This was complemented by base isolation technology at the foundation level to dampen lateral forces.

Process & Technology

  • Laser scanning and point-cloud modeling of the existing structure.
  • Collaborative 4D/5D BIM for clash detection and construction phasing.
  • Finite Element Analysis (FEA) to simulate seismic performance post-retrofit.
  • Prefabrication of major steel components off-site to reduce on-site time by 40%.
