Machine data and the quality of screw displacement piles

During the installation of piles, data are gathered which allow the machine operator to make decisions. These data about the process parameters for screw displacement piles can be used by other people and in different phases of the project, reducing the discrepancy between the levels of attention devoted to the design and the installation phases of pile foundations. In this project, pile installation databases and expert knowledge were combined in a Bayesian belief network approach to take all the information into account in a systematic way and to infer the quality of the installed piles.
