NBS describe BIM in the following way: "BIM describes the means by which everyone can understand a building through the use of a digital model which draws on a range of data assembled collaboratively, before during and after construction. Creating a digital Building Information Model enables those who interact with the building to optimize their actions, resulting in a greater whole life value for the asset."
For further information please visit the NBS National BIM Library website.
BIM objects contain information such as product properties (U-values, thermal performance, material etc), maximum and minimum size restrictions, functioning data, visual models representing product appearance and much more. These high-quality BIM models are an essential resource to any Architect, Specifier and Construction Industry Professional.
