Building information modeling


Building information modeling

(BIM)The physical and functional characteristics are set forth in a relational database format rather than in traditional drawings. BIM data reside inside the objects of building components and products, which are assembled and configured to produce a virtual model of the building. These objects contain highly accurate geometric data such as spatial coordination and a clash detection system, where interferences are identified virtually and corrected before causing expensive field changes. A BIM object also contains a variety of relevant nongraphical data, such as material strength, insulation value, finish, surface reflectivity, light transmission, or fire rating. They also carry links to other associated documentation such as technical data, warranty, and maintenance information.

generic objects

Carries geometric and nongraphical data representing the functional need but does not carry specific information that a manufacturer’s product model does.

objects

Contain different types of BIM content, related to the characteristics and installed use of the products and materials they represent.

parametric objects

BIM data available from building products manufacturers in a variety of configurations, heights, widths, thicknesses, materials finishes, hardware options, fire ratings, and energy and sound transmission.

proprietary objects

Represents a specific manufacturers’ product with its particular specifications and functional characteristics.
