Engineering & Construction
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.
This definition of Building Information Modeling in the Handbook of BIM (Eastman, Teicholz, Sacks & Liston 2011) encompasses a lot starting from a technology to embracing the whole construction process.
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 could definitely benefit from better communication and information management.
From software, BIM asks for accuracy and capability to handle lots of information, and in practice also compatibility with other solutions as otherwise achieving a collaborative workflow would be challenging at best. Tekla has chosen Open BIM and constructable models as we want to make good BIM workflows achievable for our customers.
The users list many benefits of BIM. Companies that utilize BIM, have reported benefits for scheduling, estimation and risk analysis, more collaborative processes and better facility management. BIM also brings the opportunity to try out solutions in advance before building the structure on site: with a
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 has gathered compliments for improved communication between project parties and generally better quality.
