The Building Safety Act requires a 'golden thread' of building information from design to demolition. Most building owners don't know what this means. Those who do are gaining a massive competitive advantage.. What Is the Golden Thread? The Building Safety Act 2022 introduced the concept of the 'golden thread' — a continuous chain of building information maintained throughout a building's lifecycle, from initial design through construction, occupation, and major refurbishment. The golden thread must: Be digital (not paper based) Be accurate and up to date Be accessible to those who need it Include all information relevant to building safety Be maintained by the Accountable Person Be provided to the BSR on request What Must Be Included Design and Construction Information Fire strategy report and all supporting analysis Structural fire engineering calculations Product data sheets for all fire safety products (doors, glazing, insulation, cladding) Compartmentation drawings showing every fire rated element Smoke control system design and commissioning data Fire detection and alarm system design, installation, and commissioning records Sprinkler system design, installation, and commissioning records Construction phase fire safety management plans Certificates of conformity for all fire safety installations In Use Information Fire risk assessments (current and all previous) Fire safety management plans Maintenance records for all fire safety systems Resident engagement records Safety occurrence reports Building assessment certificate Safety case report Change control records The Technology Landscape BIM Based Solutions Autodesk Construction Cloud — integrated design and construction management Asite — government endorsed golden thread platform Zutec — specialised building safety information management Operance — digital handover and golden thread for operations Active Plan — fire safety information management for in use buildings Key Features to Look For 1. Audit trail — every change recorded with who, when, and why 2. Access control — role based access for different stakeholders 3. API integration — connecting with design tools, FM systems, and IoT 4. Regulatory compliance — built in workflows for BSR submissions 5. Resident access — portal for residents to view relevant safety information 6. Mobile capability — field data capture during inspections and maintenance The Cost of Getting It Right vs. Getting It Wrong Approach Cost (50 storey residential) Risk Retrospective paper digitisation £150,000 £300,000 High — accuracy uncertain Purpose built platform from design £80,000 £120,000 Low — information born digital No golden thread (non compliance) Unlimited Very High — criminal offence Magnus Opifex integrates golden thread requirements into every project.
