Definition of BIM (Building Information Modeling)
“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.” - Building Information Modeling in the Handbook of BIM (Eastman, Teicholz, Sacks & Liston 2011)
Construction Software Enables Collaboration and Information Management
At Tekla, we think the "I" in BIM is especially important. In the US, the National Building Information Model Standard (NBIMS-US™) Project Committee sees Building Information Models as essential shared knowledge resources for information about a facility.
Working with others can be a pain point in a project. According to the NBIMS-US™ Project Committee, “Buildings cost more than they should to design, build and sustain and they take too long to deliver. We must do a better job of collaborating between the many stakeholders involved in the building process.” In the US, a study by NIST shows that lack of interoperability causes owners an additional cost of $15.8 billion dollars every year. The construction industry meeds better communication and information management in order to stay profitable and efficient.
BIM means having the accuracy and capability to handle lots of information, along with necessary compatibility with other software solutions to achieve a truly collaborative workflow. Tekla utilizes Open BIM and constructible models in order to make efficient BIM workflows easily attainable fo our customers.
Benefits of BIM Span Across the Whole Construction Management Process
Companies currently using BIM, like Skanska and Barton Malow, consistently report benefits in scheduling, estimation and risk analysis, as well as more collaborative processes and better facility management. BIM also allows the opportunity to try out solutions in advance before building the structure on site. A constructible model can be prototyped virtually so all project parties can understand and review the design more easily, which helps guarantee its accuracy and completeness, and visualize and evaluate alternatives in terms of cost and other project parameters.
BIM is Not Everywhere
All construction software models and drawings representing a building are not necessarily BIM. For example, if a model contains visual 3D data but doesn't show object attributes, or allows changes to dimensions in one view but doesn't automatically reflect those changes in other views. These examples miss the above-mentioned, necessary data for supporting the construction, fabrication and procurement.
