“…The smart excavator used in this study was developed by Oulu University's Civil Engineering Research Unit from a standard Bobcat E85 Compact excavator. It is fully automated and can be operated with four different control methods (Immonen, 2014and Heikkilä et al, 2019and Mehmood et al, 2021. The first is typical manual operation mode, whereby a pilot operates the controls of the excavator from inside the cockpit.…”

The assessment of soil parameters in construction holds significant importance for refining building information modeling (BIM). Our study aimed to investigate the adaptive utilization of pressure sensor data as a dynamic and computationally efficient tool for this purpose. The results reveal a significant correlation between the pressure sensor readings of the hydraulic cylinder in the excavator bucket and the total load during static-dynamic penetration tests conducted in both homogeneous and heterogeneous soil. This correlation holds true across a 100% range of torque, with values recorded at 0.60 and 0.93, respectively. A key strength of this methodology lies in that it enables near real-time detection of verified boundary levels. This feature streamlines the adoption and development of BIM-based excavation methods that seamlessly align with current practical conditions. Keywords: Soil boundary, detection, hydraulic pressure, static-dynamic penetration test, correlation, model-based design, ground investigation.
