Abstract
This case history involves the foundation and site liquefaction potential evaluation for the renovation of a one-hundred-year old building. The subject project is a four story structure with one basement, built of thick masonry walls and supported on shallow foundations. The project site is located in a seismic zone 3 per UBC. The subsurface geology consists of alluvial inter-bedded layers of silt, sand, and clay. Substantial additional loads were considered during the proposed renovation, and thus an extensive study on the foundation and geotechnical aspects of the project were required, including site geology, evaluation of bearing capacity and settlement, evaluation of factors of safety on bearing capacity before and after the proposed renovation, and evaluation of the liquefaction potential. Foundation aspects and boundary conditions of new elements for seismic retrofit (such as shear walls) added to the existing structure are also presented.
