The goal of this thesis is to develop an appropriate and adaptable simulation module for microtunnelling construction operations. It helps to analyze the processes and to identify the factors, which influence the operation productivity of the
construction process essentially. In view of these objectives, a System Modeling Language (SysML) model describing the microtunnelling process is developed in the first step. Subsequently, the simulation software AnyLogic is applied to create the MiSAS
(Microtunnelling: Statistics, Analysis and Simulation) simulation module based on the SysML formalization. Three actual microtunnelling projects at the city of Recklinghausen, Germany, are used for the validation, verification of the developed MiSAS
module. Thereafter, the MiSAS module allows to evaluate the impact of the different ground conditions, disturbances and predict the resulting tunnel productivity.
