This document discusses building information modeling (BIM) tools and data formats. It includes the following: 1. A table listing various BIM tools for massing, design, construction management, cost estimation, structural analysis, and energy analysis. 2. A table listing common 3D surface/shape and 3D object file formats used for BIM such as OBJ, IFC, STP. 3. A diagram showing how different engineers and building professionals can collaborate using a shared IFC model during design and construction.
