Abstract
Limited space in urban area makes it attractive to reuse the existing foundation. This paper presents a case study on the use of seismic piezocone penetrometer (SCPTu) to conduct parallel seismic test for the determination of the length of unknown foundation. The tip resistance and side friction by cone penetrometer provide the distribution of mechanical properties of the underground layer. The geophones in seismic piezocone tip acts as seismic wave receiver for parallel seismic test that is commonly used to determine the length of unknown foundation. By fusion of both information, the capacity of pile foundation under existing building can be determined. This testing procedure is very attractive for reuse of existing foundations. A case study is provided on the use of SCPTu in a building expansion project.
