The Olive Plaza Building was originally constructed in the 1980s. Miyamoto provided a seismic rehabilitation for this existing 12-story, 108,000-SF concrete lift-slab building to meet requirements set forth by the Department of Housing and Urban Development (HUD). The Phase 1 structural investigation showed that the existing reinforced concrete shear walls were deficient for seismic loading based on HUD requirements. The understrength of the walls was solved by implementing super thin Fiber Reinforced Polymer strips to strengthen the concrete. In some locations, concrete pilasters were added but limited in both size and number to minimize the impact on tenants. This technique, as opposed to an all-concrete solution, reduced the number of finishes that had to be removed and replaced, reducing, in turn, the overall construction cost.
