Pertains to the creation and use of generic objects and manufacturer's product objects.

This part of BS8541 extends the recommendations in BS8541‑1 to cover purposes for characterizing the shape and measurement of construction library objects for use in the building construction and facility domain. It applies to the creation and use of generic objects and manufacturer’s product objects.

NOTE Providers of generic and manufacturer’s product objects can provide information to support additional purposes including measurement and spatial coordination.

It gives recommendations for the application of construction objects in integrated BIM working for spatial and construction coordination, quantity take-off and visualization. It defines the level of detail appropriate for specific uses and provides representations of measurements for characterizing the library object where geometric shape is not relevant.

Where a project is formally committed to integrated working, this British Standard may be adopted as a requirement on the design team and/or the procurement chain. For other situations, this British Standard gives recommendations of best practice.
