Factory Remodel Carrington Seismic Retrofit Richlen Construction started installing davit bases for a new swingstage system on a renovated high-rise building based on another company’s design.  Richlen discovered that the bases were too low to be waterproofed; also, the swingstage davits could not be attached to the bases.  We redesigned the roof access and davit bases to overcome both of these problems and improve overall life-safety without delaying construction.
