What is the golden thread?

The Golden Thread brings together information that demonstrates how building safety risks have been identified, managed and controlled. While the exact content will vary depending on the building and scope of works, it typically includes:

• Design and construction information relevant to building safety
• Fire safety strategies and supporting documentation
• Records of key decisions, assumptions and changes
• Information required for safe occupation and ongoing management
• Documentation supporting Gateway 2 and Gateway 3 submissions

The emphasis is on information that is accurate, coordinated and capable of being relied upon over time.

Golden Thread requirements apply throughout the lifecycle of a Higher-Risk Building, beginning at design stage and continuing through construction, completion and occupation.

Information developed for Gateway 2 and Gateway 3 submissions typically forms a key part of the Golden Thread and must be capable of being maintained and updated beyond handover.

Early consideration of Golden Thread requirements helps avoid gaps or inconsistencies later in the project.

Responsibility for the Golden Thread sits across different dutyholders at different stages of a project. During design and construction, responsibility is shared between the client and appointed dutyholders, including the Principal Designer.

Following completion, responsibility for maintaining the Golden Thread information typically sits with the building owner or Accountable Person.

Clear allocation of responsibility is essential to ensure that information remains accurate, accessible and usable over time.

Golden Thread requirements apply most explicitly to Higher-Risk Buildings under the Building Safety Act. However, the principles of coordinated and reliable information management are relevant to all complex residential projects, particularly where fire safety and regulatory compliance are critical.

The Building Safety Act does not prescribe a specific digital system. What matters is that information is accurate, accessible, secure and capable of being updated over time.

A well-structured Golden Thread supports effective change control and helps ensure that information relied upon at Gateway stages remains valid as a project evolves.
