With BIM (Building Information Modeling) technology, one or more accurate virtual models of a building are constructed digitally. They support design through its phases, allowing better analysis and control than manual processes. When completed, these computer-generated models contain precise geometry and data needed to support the construction, fabrication, and procurement activities through which the building is realized. BIM offers improved 3D visualization, improved productivity due to easy retrieval of information, increased coordination of construction documents and reduced costs. We use Tekla BIMsight to prepare an interactive model that represents the design, construction or operations of a building to improve collaboration between all involved parties in the project.
