The Golden Thread: Digital Building Information and the Building Safety Act

The Golden Thread requires comprehensive, accurate, up-to-date digital records of building safety information throughout a building's lifecycle. Here's what you need to know.. What Is the Golden Thread? The Golden Thread is a concept introduced by Dame Judith Hackitt's Independent Review of Building Regulations and Fire Safety (2018) and enshrined in the Building Safety Act 2022. Definition The Golden Thread consists of: 1. Building safety information — the information itself (documents, drawings, data) 2. The information management system — the digital platform used to store and manage the information What Information Must Be Included? As built drawings — accurate floor plans, sections, and details Fire strategy report — current fire engineering strategy Fire risk assessment — current FRA and action plan Structural information — structural design, calculations, surveys Building services information — M&E design, commissioning records Products and materials — specifications, test certificates, certificates of conformity Maintenance records — planned and reactive maintenance history Safety Case Report — for higher risk buildings Mandatory Occurrence Reports — records of safety occurrences Key Principles Accurate : Information must reflect the actual as built condition of the building. Accessible : Information must be accessible to those who need it, when they need it. Up to date : Information must be updated when changes occur. Durable : Information must persist throughout the building's lifecycle. Secure : Information must be protected from unauthorised access or modification. Digital Requirements The Golden Thread must be kept in a digital format that is: Machine readable Interoperable with other systems Searchable Version controlled Audit trailed BIM and the Golden Thread Building Information Modelling (BIM) provides a natural framework for the Golden Thread: Geometric model — 3D representation of the building Data rich objects — components with associated fire safety data Common Data Environment (CDE) — managed digital platform COBie data drops — structured data exchanges at project milestones For Golden Thread implementation guidance, contact Magnus Opifex.
