The Golden Thread Explained
Understanding and implementing the Golden Thread requirements for Higher-Risk Buildings under the Building Safety Act 2022.
What is the Golden Thread?
The "Golden Thread" is a concept introduced in Dame Judith Hackitt's Independent Review of Building Regulations and Fire Safety following the Grenfell Tower tragedy. It refers to a comprehensive, digital record of building information that must be created, maintained, and kept accessible throughout a building's lifecycle.
The Building Safety Act 2022 made this concept a legal requirement for Higher-Risk Buildings (HRBs) in England. The Golden Thread is not just a collection of documents but a living system that ensures critical safety information is available to those who need it, when they need it.
Key Principles of the Golden Thread
The Golden Thread information must adhere to several key principles
Digital by Default
Information must be stored digitally in a way that is secure, accessible, and searchable. Paper-based systems are no longer sufficient for meeting regulatory requirements.
Single Source of Truth
The Golden Thread should serve as the definitive source of information about a building's design, construction, and ongoing safety management. This means eliminating duplicate or contradictory information.
Accessible and Usable
Information must be accessible to those who need it, including the Building Safety Regulator, emergency services, and residents (where appropriate). It should be presented in a way that is usable and understandable.
Current and Accurate
The information must be kept up-to-date, with changes to the building promptly reflected in the Golden Thread. There should be clear processes for updating information and maintaining version control.
Essential Components of the Golden Thread
A comprehensive Golden Thread should include the following types of information
Design and Construction Information
- Architectural plans and specifications
- Structural designs and calculations
- Fire strategy documents
- Materials specifications and test certificates
- As-built drawings
- Construction quality assurance records
Safety Management Information
- Fire risk assessments
- Structural assessments
- Safety management systems documentation
- Emergency procedures
- Evacuation plans
Maintenance and Inspection Records
- Maintenance schedules and records
- Inspection certificates
- Testing records for safety systems
- Repair and remediation documentation
Change Management Records
- Documentation of all changes to the building
- Impact assessments for changes
- Approvals and sign-offs
- Updated drawings and specifications
Implementing the Golden Thread: Step-by-Step
Follow these steps to implement an effective Golden Thread system for your Higher-Risk Buildings
1Gap Analysis
Begin by assessing what information you currently have and identifying gaps. This will help you prioritize your efforts and allocate resources effectively.
- Identify all the information you need for the Golden Thread
- Assess what information you already have and its format (paper, digital, etc.)
- Identify missing or incomplete information
- Prioritize information gathering based on safety criticality
2Select a Digital Platform
Choose a digital platform that can handle the complexity and volume of information required. This might be a specialized building information management system, a document management system with appropriate features, or a custom-built solution.
Consider factors such as security, accessibility, user-friendliness, version control, search capabilities, and interoperability when selecting your platform.
3Establish Governance
Define roles and responsibilities for managing the Golden Thread. This should include who can add, modify, or approve information, as well as processes for quality assurance.
- Assign overall responsibility for the Golden Thread
- Define who can add, modify, and approve information
- Establish quality assurance processes
- Define how information will be reviewed and updated
4Create a Standardized Structure
Develop a consistent structure for organizing information that makes it easy to navigate and find specific documents. This might be based on building systems, spatial organization, or a combination of approaches.
5Digitize and Organize Information
Convert paper documents to digital format and organize all information according to your standardized structure. Ensure information is properly tagged and searchable.
- Scan paper documents at appropriate resolution
- Use OCR (Optical Character Recognition) to make documents searchable
- Add appropriate metadata and tags
- Organize according to your standardized structure
6Implement Access Controls
Set up appropriate access controls to ensure information is accessible to those who need it while maintaining security. This includes external stakeholders like the Building Safety Regulator and emergency services.
- Define access levels for different user groups
- Implement secure authentication methods
- Create processes for granting access to external stakeholders
- Maintain audit trails of access and changes
7Train Staff and Stakeholders
Provide training for all those involved in creating, maintaining, or using the Golden Thread. This includes in-house staff, contractors, and potentially residents.
Ongoing training and support are essential to ensure the Golden Thread is maintained effectively over time. Regular refresher sessions and updates on new features or processes should be provided.

Enhance the effectiveness of your Golden Thread with these best practices
Start Small and Scale Up
Begin with a pilot project or a single building before rolling out to your entire portfolio. This allows you to refine your approach and identify challenges early.
Focus on Quality, Not Just Quantity
Prioritize the quality and accuracy of information over the quantity. It's better to have comprehensive, reliable information about critical safety systems than to have superficial information about everything.
Integrate with Existing Systems
Where possible, integrate your Golden Thread with existing systems such as asset management or maintenance management systems to avoid duplication of effort.
Implement Robust Version Control
Ensure your system maintains a clear history of changes to documents and information. This is essential for audit purposes and for understanding the evolution of the building over This is essential for audit purposes and for understanding the evolution of the building over time.
Ensure Interoperability
The Golden Thread information should be stored in formats that are interoperable and not locked into proprietary systems. This ensures the information can be transferred if necessary and remains accessible over the long term.
Regular Reviews and Updates
Schedule regular reviews of your Golden Thread information to ensure it remains current and accurate. This should be done at least annually and after any significant changes to the building.
Overcoming Common Challenges
Address these common challenges when implementing your Golden Thread
Historical Buildings with Limited Documentation
For older buildings, comprehensive documentation may not exist.
Solutions:
- Commission surveys to establish current conditions
- Create new baseline documentation
- Document assumptions and limitations clearly
- Implement a phased approach to building up the Golden Thread
Integration of Multiple Systems
Many organizations already have multiple systems containing building information.
Solutions:
- Map existing systems and data flows
- Identify a primary system to serve as the Golden Thread repository
- Develop integration strategies or manual processes to ensure consistency
- Consider middleware solutions where appropriate
Resource Constraints
Implementing a comprehensive Golden Thread system requires significant resources.
Solutions:
- Take a phased approach, focusing first on critical safety information
- Leverage existing systems where possible
- Consider shared services or external support
- Develop a long-term resource plan
Cultural Resistance
Implementing new systems and processes often faces resistance from staff accustomed to existing ways of working.
Solutions:
- Involve key stakeholders in the planning and implementation process
- Communicate the benefits and importance of the Golden Thread
- Provide comprehensive training and ongoing support
- Celebrate early successes and share them widely
