1. THE GOLDEN THREAD OF FIRE SAFETY INFORMATION AND ITS IMPORTANCE. 2. Golden THREAD TASK FORCE - REVIEW OF FIRE SAFETY & BUILDING HANDOVER INFORMATION 27-02-2026
Meeting Summary
Date: 27 February 2026
Duration: Approximately 52 minutes of recorded discussion
Meeting Objective
The meeting focused on strengthening the practical implementation of the Golden Thread, with particular emphasis on building safety management, change control, handover information, verification of O&M documentation, safety-critical assets and the use of digital technologies to improve information quality. The session also demonstrated how the Golden Thread Task Force brings together designers, contractors, fire engineers, clients and other specialists to share knowledge and develop practical, interoperable solutions.
1. Building Safety Management and Mandatory Reporting
The opening presentation highlighted the importance of maintaining effective building safety management systems and reporting serious safety issues to the regulator. Particular attention was given to Mandatory Occurrence Reporting (MOR), including the need to report serious threats to the safety of multiple people and significant fire-safety non-conformities such as failures in fire compartmentation.
The discussion also covered Safety Case Reports, which need to address both fire and structural risks. Effective safety cases should identify and rank risks, assign ownership, establish control measures and demonstrate why the building is considered safe.
2. Change Management
A major theme was the importance of formal change management throughout the life of a Higher-Risk Building. The meeting highlighted that changes should be anticipated, controlled and documented through an appropriate change-management process and register.
Three categories of change were discussed:
-
Major changes
-
Notifiable changes
-
Recordable changes
Changes affecting fire safety measures or the fire and emergency information need particular attention, with major changes requiring appropriate engagement with the Building Safety Regulator.
The group also emphasised the importance of capability statements, duty-holder statements and client declarations confirming compliance with building regulations for construction and refurbishment work.
3. Evidence Before Client Sign-Off
A strong concern was raised regarding clients being asked to sign completion or compliance declarations without receiving sufficient supporting evidence.
Participants agreed that clients should not be expected to confirm compliance simply because a project has reached completion. Evidence must be available before acceptance and sign-off, and fire-safety/building-safety practitioners need to work more closely with estates and project-management teams.
A practical example demonstrated why this is important: inappropriate and incorrectly installed fire dampers were identified across multiple blocks, showing that simply confirming that an item exists does not demonstrate that it is correctly installed or compliant.
4. Golden Thread and Information Management
George Stevenson explained that the Golden Thread work is centred on information management rather than 3D modelling alone. The objective is to ensure that information produced during development and construction supports subsequent construction and operational activities.
The Task Force has developed standardised approaches to classification, safety-critical assets and digital records, bringing together subject-matter experts from different parts of the industry.
Work has included safety-critical assets such as fire doors, cavity barriers, sprinkler systems, smoke dampers and AOVs, considering the risks they mitigate, how they can be compromised, the information required about them, competency requirements and how product changes should be recorded.
5. Connecting Information to Create the Golden Thread
The meeting demonstrated how different information sources—including BIM models, CAD drawings, COBie data, O&M documentation, schedules and 360° photographs—can be connected.
The objective is to establish a clear relationship between the asset, its location, supporting documents, inspection information and relevant safety requirements. This can provide a much stronger and more usable Golden Thread than keeping information in disconnected files and folders.
The approach can also be applied retrospectively to existing buildings where fully developed BIM models are not available.
6. O&M Information and Handover Auditing
A live project example demonstrated significant problems with traditional O&M handover packages. A large head-office project contained approximately 16,000 documents, of which around 6,000 were identified as duplicates. The team manually reviewed 54 work packages and identified defects including missing testing, commissioning and warranty information.
The audit methodology is now being developed to support AI-assisted checking, with manual audits being used to establish reliable results before applying the LLM-based process.
The intention is for audit reports to be returned to contractors and their supply chains so that missing or defective information can be corrected.
7. Information Quality and Coordination
Examples showed that information can appear complete while still containing serious coordination problems.
Issues identified included:
-
Missing asset/tag numbers connecting the BIM model, COBie data and schedules.
-
Significant differences between door types recorded in the model and O&M documentation.
-
Incorrect or duplicated door references across different floor drawings.
-
Drawings being manually edited without the resulting inconsistencies being detected.
The meeting emphasised that these issues need to be identified before an emergency occurs, rather than being discovered when the information is urgently required.
8. Warranties and Defects in Handover Information
The discussion identified missing warranty start dates as another recurring handover defect. Without knowing whether a warranty starts at purchase, installation or commissioning, building owners may incorrectly assume that equipment is out of warranty and incur unnecessary replacement costs.
Participants also considered incomplete information to be a handover defect, meaning that clients may have recourse to require corrections during the defects liability period. This can benefit both clients and contractors because unresolved information defects can create liabilities that continue well beyond project completion.
9. Role of the Golden Thread Task Force
The Task Force was described as a collaborative group established to help achieve the Golden Thread through knowledge sharing and practical industry solutions.
Its membership includes designers, contractors, fire engineers, clients and other specialists, with the aim of combining different areas of expertise rather than expecting a single organisation to solve every aspect of the Golden Thread independently.
The group stressed that collaboration is particularly valuable when surveying or digitising existing buildings. For example, a survey company may capture floor plans, but specialist fire-safety expertise is needed to correctly identify fire compartments and other safety-critical information. Combining these skills can make the investment more effective.
10. CROSS and Industry Learning
Alistair Sone introduced CROSS (Collaborative Reporting for Safer Structures) and explained the role of voluntary confidential reporting in identifying safety problems before they become more serious.
The initiative encourages professionals to report issues involving areas such as fire doors and dampers so that lessons can be shared, advice can be provided and recurring problems can be identified across the industry.
Key Takeaways
-
Evidence must underpin compliance — clients should not sign declarations without receiving appropriate supporting evidence.
-
Change management is essential and should be formally embedded within building safety processes.
-
The Golden Thread is fundamentally about connected information, not simply 3D BIM models.
-
Safety-critical assets require consistent information covering their risks, operation, inspection, competence and changes.
-
O&M and handover information requires active auditing; simply receiving a large volume of documents does not demonstrate completeness or quality.
-
BIM, COBie, CAD, photographs and documents should be connected to create a reliable and searchable information record.
-
AI can support information auditing, but manual verification remains important for establishing confidence in automated results.
-
Collaboration between clients, designers, contractors, fire engineers, surveyors and technology specialists is essential to delivering an effective Golden Thread.
Overall Conclusion
The meeting reinforced that the Golden Thread should be treated as a practical, continuously maintained information system supporting building safety, rather than simply a collection of handover documents. Stronger evidence, structured change control, connected asset information, rigorous O&M auditing and multidisciplinary collaboration were identified as key to improving the reliability of building-safety information throughout the building lifecycle.
