Abstract:
In Rotterdam in the Netherlands the project ‘De Zalmhaven’ is being developed. The project
consists of the realization of houses, parking facilities, two residential towers of 70 m and a
residential high rise of 215 m. An artist impression for the project is given in figure 1. For the high rise a new development in the use of large diameter, drilled piles with a steel casing
has been successfully utilized. In this article the installation method of 65 m long steel drilled
piles in two consecutive sections is presented. The settlements for the building (and the
influence on its surroundings) have been analyzed in detail using 3D Finite Element
calculations, which will also be discussed. Finally there is focus on the results of settlement
measurements carried out during construction in relation to the settlement prognosis.
