Casa Grande in New Almaden

Langan performed the geotechnical investigation and consultation for the renovation of the Casa Grande in the New Almaden District for expanded museum use.  The rehabilitation included construction of in-fill walls and other small structural elements, and also included installation of a braced frame to seismically strengthen the structure. The purpose of our study was to address the geotechnical and seismic hazard issues at the site and provide geotechnical recommendations for new foundations to support new structural elements.
