Abstract: Foundation type selection is an important content of the building structure design that is related to the overall safety of the building structure. Currently, the selection of foundation type is made based on the geological and hydrogeological conditions, topographical conditions, superstructure information and experience of the structural engineer and throughout the settlement and bearing resistance estimations. This paper combines the concept of the forward design in the Boulding Information Model (BIM) in the foundation type selection design and subsurface conditions are represented by the Revit geological model. So that the stratigraphy of soil and rocks can be visualized. The foundation embedment and dimensions are presented visually in the BIM system. The advantage of using BIM system is that the selection of foundation system can be accelerated throughout the visualization.  

Key words: foundation structure, geological model, foundation comparisons, forward design, building information model
