building Information Modelling (BIM) is a digital process for creating, managing, and sharing information about a built asset throughout its lifecycle, from design and construction to operation and maintenance. It enables collaboration among stakeholders using a shared digital model to improve efficiency, reduce costs, and enhance decision-making.

British Standards for BIM:

1. BS EN ISO 19650 Series – Organization and digitization of information about buildings and civil engineering works, including BIM
   
   • BS EN ISO 19650-1:2018 – Concepts and principles of BIM
   • BS EN ISO 19650-2:2018 – Information management during the delivery phase
   • BS EN ISO 19650-3:2020 – Information management during asset operation
   • BS EN ISO 19650-5:2020 – Security-minded BIM implementation
2. BS 1192:2007+A2:2016 – Collaborative production of construction information
   
   • Establishes best practices for file naming, data structuring, and collaborative workflows in BIM projects.
3. PAS 1192 Series (now largely replaced by ISO 19650 but still referenced)
   
   • PAS 1192-2:2013 – BIM for capital/delivery phase
   • PAS 1192-3:2014 – BIM for asset management

These standards ensure that BIM is implemented consistently across projects, improving efficiency, accuracy, and collaboration within the construction industry.
