Pertains to the design of generic objects and manufacturer's specific products.

This part of BS8541 builds on the recommendations in BS8541‑1 to cover purposes for specifying and assessing attributes for construction library objects for use in the building construction and facility industry. It applies to the design of generic objects and manufacturer’s specific products.

This British Standard gives recommendations for the application of construction objects in integrated BIM working for specification and selection. It defines the level of information appropriate for specific uses including specification of the desired outcome (typically by designers and engineers) and the selection of identified products (typically by contractors and sub-contractors). It covers both common attributes (colour, material, finish, etc.) and examples of specific attributes (fire resistance, etc.). It also gives recommendations for the assessment of expected impacts.

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.
