- Work included reducing the overall floor plate size on each end of every floor in the entire Central Wing Tower increasing the seismic separation of the structure from 4 inches to 14 inches. Seismic joints were created in all MEP and FLS systems to allow for added seismic movement.
- Chilled water piping extended to accommodate the increase of seismic structure expansion.
- Won door added next to corridor expansion joint for fire safety
- Web stiffeners and tie beams were added to existing columns.
