Cobb Building Renovation

MKA followed FEMA 356 Prestandards for the seismic renovation of this 11-story Beaux-Arts building constructed in 1909 and listed on the National Register of Historic Places.  The building was converted from offices to residential apartments and underwent various upgrades, earning LEED Silver certification. MKA’s conversion design included a concrete shear wall outside the building, at the re-entrant corner of the existing “L”-shaped plan.  This approach facilitated the development of apartment space throughout the tower, reduced the core costs and overall construction schedule by 25 percent, eliminated the need for penetration by structural floor elements, and allowed a tower crane to assist with rebar placement. Civil elements include on-site and off-site civil engineering, including coordination of the storm water control requirements and improvement of the sidewalk surface while maintaining the existing curb location. One curb bulb was planned for the University Street and Fourth Avenue corner.
