Shoring elements could be reconfigured as soil data was received from new boreholes. By including new construction elements, Stephenson Engineering was able to avert several major conflicts between existing and new features below grade. By using the BIM model as a data clearing house for all project information, we were provided with a single access point for all material that would influence and impact the final design, mechanical layouts, and coordinating precast concrete panels STEPHENSON ENGINEERINGBUILDING INFORMATION MODELING 04'
