The building remained partially occupied throughout the construction phase, requiring a phased retrofit strategy that maintained structural integrity and life-safety at all times. Existing drawings were incomplete, demanding thorough field investigation and destructive testing to verify as-built conditions before any analysis could begin.

The existing concrete shear wall system had significant deficiencies in shear capacity and connection detailing. The solution required adding new lateral elements while carefully managing load path continuity through each construction stage — demanding close coordination between structural design and construction sequencing.
