In Building Information Modeling (BIM), subsoil models are interpolated from information obtained from ground investigations. Our study focused on the adaptive use of geological uncertainty modeling to derive additional information during excavation. The results show that the continuous mapping of excavated ground is an effective estimation tool for modeling boundary levels. This adaptive tool can significantly decrease uncertainty in earthwork, presenting new possibilities for productivity and sustainability. The results of this study enable comparisons of alternative options in adaptive uncertainty modeling during excavation, allowing for the development of uncertainty-based subsoil models for construction.
