To define the BIM or Building Modelling Information, The US National Building Information Model Standard Project Committee has the next description:
Building Information Modeling (BIM) is a Computational illustration of physical and functional features of a facility. A BIM is a shared information source for info about a facility creating a dependable basis for decisions throughout its life-cycle; defined as current from original conception to destruction.
Old-style structure design was mainly dependent on 2D technical sketches (plans, elevations, sections, etc.). Building Information Modeling expands this beyond 3D, augmenting the three primary spatial dimensions (width, height and depth) with time considered as the fourth dimension (4D) and price as the fifth dimension (5D). BIM therefore gives more information than just dimensions. It also covers spatial relations, light analysis, geographic information, and measures and properties of structure contents (such as constructors’ details).
BIM includes demonstrating a design as groupings of “objects” – unclear and vague, basic or product-specific, solid shapes or
