3D visualization of interpolating geotechnical strata in a BIM environment and estimating the volume

As a result of the development occurring recently in the construction industry and infrastructure development, with respect to the importance of the geotechnical aspect in this field, the two-dimensional representation unable to develop the complete picture of the soil characteristics. Therefore, the necessity to create a three-dimensional representation of the soil layers can be considered as crucial element. The 3D model will provide the required clarity among soil information in the process of integrating designs between different disciplines. Moreover, it will be facilitating the work environment and anticipating potential risks which caused previously by lack of information. This research investigates the process of integrating the information obtained by spatial interpolation techniques using “GIS” environment in order to divide areas according to construction safety zoning by transferring the obtained information to a “BIM” environment (Civil3d) and representing soil layers. The area of study in this research is located in the Tanuma area in Basra Governorate, which consists of 19 boreholes extending to a depth of 45 meters, including 332 SPT and 360 soil descriptions. The research relied specifically on SPT values in order to divide the areas according to OSHA regulations
