This project focuses on the design of a foundation and garage-level retaining walls for a 25 story building in Oakland, California. The design was completed through the use of data from a 1988 soil investigation and provided structural loads. The site is composed of a thin sand layer above a clay layer about 400 feet thick. Analysis included soil and groundwater conditions and exploration of spread footings, mat footings, and pile foundations. The final selected foundation type is driven piles with the other options discarded due to lack of data and an unsuitability for the structure requirements. Piles are suitable for the deep, strong soils underlying the work site and the massive loads of the structure. Pile capacity and settlement of the final foundation design, as well as the strength of the designed retaining walls, safely met all project requirements. Additional recommendations were made in order to ensure accurate foundation construction.
