According to PAS 1192-2:2013: Specification for information management for the capital/delivery phase of construction projects using building information modelling (BIM), an assembly is a:

'Group of components or types to enable the reuse of standardised design or specification elements improving productivity of design and delivery as well as providing a location to hold specifications and lessons learnt in a simple and useable way. They may hold benchmark data for cost and carbon impacts.

The contents of assemblies may themselves have attributes and classifications. These properties may include key data which is attached (to the object) for use once it is placed into a model and may include cost, CO2, programme, maintenance and other key information.'

Sub-assemblies are: 'Major building elements that are manufactured offsite, potentially using other offsite manufactured components. Examples include balustrading assemblies, facade cassette panels and preassembled M&E elements.' Ref BIM Overlay to the RIBA Outline Plan of Work, published by the RIBA in 2012.
