The Golden Thread of building information is a cornerstone of the Building Safety Act. We explain what it means in practice and how to implement it effectively.. What Is the Golden Thread? The Golden Thread is a comprehensive, accurate, and up to date digital record of building safety information. Required for all higher risk buildings under the Building Safety Act 2022. Key Requirements Content Original design documentation Fire strategy and fire risk assessments Structural safety information Construction phase records and change control Maintenance records Safety case report Format Must be digital and in a prescribed format Accessible to relevant persons (BSR, building safety manager, residents) Searchable and retrievable Version controlled Lifecycle Created during design Maintained during construction Updated throughout occupation Transferred on ownership change Implementation Approaches BIM Based Integrating the Golden Thread with the building's BIM model ensures spatial data is linked to safety information. Document Management For existing buildings without BIM, cloud based document management systems with standardised tagging provide a practical solution. Hybrid Most buildings will use a combination — BIM for new build elements and document management for legacy information. For Golden Thread implementation, contact us.
