What is building information modelling (BIM)?
Building information modelling (BIM) is the creation and use of coordinated, internally consistent, computable information about a building project in design and construction. The ability to keep this information up-to-date and accessible in an integrated digital environment gives architects, designers, engineers, builders and owners a clear overall vision of their projects and contributes to the ability to make better decisions faster, helping increase project quality and profitability. For more information about building information modelling and Autodesk’s strategy for the application of information technology to the building industry, see the white papers and other information at www.autodesk.com/powerofbim.
BIM is the most comprehensive way to author, construct and maintain buildings. Its main advantage lies in 3D modelling, teamworking and co-working on projects, communication and mobilizing information. BIM helps workflows become faster and diminishes unnecessary communication and errors.
