Lathe and plaster demolition, foundation removal and replacement were completed by Weinstein Construction Company of Van Nuys. The foundation depth and steel work were specified by the project engineer in consideration of expansive clay soils. In the first photograph, look for a quarter balanced on a lateral piece of rebar to indicate scale.
This component of the project included replacement of the perimeter foundation with piers on posts supporting girders and floor joists. The piers are spaced on a grid about 60 inches on center.
