Taft Building Seismic Retrofit

Taft Building Seismic Retrofit

Morley provided concrete services for this voluntary seismic retrofit of a historic cast-in place concrete building. The project required demolition of 3,000 sf of existing 5″ thick basement slab, including approximately 400 cubic yards of native soil and 150 cubic yards of over-excavation at existing fill soils. Morley installed new 42-48 inch deep grade beam foundations and 14- 20 inch thick concrete (shotcrete) shear walls from the new foundations in the basement up to the roof line at the 12th floor.


The building was occupied during construction, and was performed after hours to minimize impacts to the tenants. Morley did not provide demolition or replacement of finishes in our scope of work.
