ABSTRACT

This paper presents the design of foundation for two high-rise buildings in Jeddah, Kingdom of Saudi Arabia. The foundation system for each of the towers consists of large diameter bored piles founded on Coralline Limestone. The paper describes the geotechnical investigation program and results, the various load cases from the buildings and the design process. A 3D FEM program, Plaxis 3D Foundation was used for the analysis of the pile foundation. Instrumented ultimate pile load tests were carried out on site. The results of the tests were assessed and used to check the design assumptions and verify the model of the 3D Foundation.
