Abstract

The paper describes a case history that illustrates a mixed foundation system in which existing caissons which previously supported an 11-story building that had been demolished down to street level, share the load with a mat constructed in the lowest basement level on top of the existing caissons to support a new 38-story office building. The geotechnical investigation to determine the properties of the supporting soil strata is described as well as the material investigation to confirm the integrity of the existing foundations. The soil structure interaction concept developed and the analysis performed is presented. The observed settlement is compared with the predicted settlements with reasonable agreement reached.
