Solutions for Principal Contactors
Principal Contractors assemble the handover record that proves what was delivered
NBR helps you create a structured, defensible digital handover and preserves the audit record post-completion
Supporting the Responsibilities of the Principal Contractor
Principal Contractors play a critical role in coordinating delivery and ensuring that required information is prepared for handover. While the Building Owner ultimately holds the Golden Thread record, Principal Contractors are responsible for assembling and handing over evidence that demonstrates what was delivered.
In practice, buildings change hands, teams move on, and client systems vary widely. If work is ever reviewed, challenged, or audited, the question is rarely where the information is stored.
It is whether the handover record is complete, accessible, and able to stand up to scrutiny.
NBR supports Principal Contractors by providing a structured place to assemble handover-ready information, and by preserving the obligated audit record post-completion.

Your Challenges
Principal Contractors commonly face:
-
Coordinating handover information across multiple subcontractors and suppliers
-
Pulling together evidence under time pressure as completion approaches
-
Ensuring handover information is complete, usable, and defensible
-
Losing visibility or control of records once the building is handed over
-
Being asked to evidence what was delivered months or years later
Why Principle Contractors use NBR
Principal Contractors use NBR to:
-
Assemble a clear, structured record ready for handover
-
Maintain an independent audit record of what was delivered
-
Protect against information being lost, diluted, or refiled after completion
-
Demonstrate that required evidence was collated and provided in a usable form
-
Reduce handover risk by keeping critical records in one consistent place
How We Can Help
NBR does not manage document activity during construction.
What we do is provide a structured place for you to start assembling Golden Thread information in preparation for handover, then host the obligated audit record post-completion so it remains accessible, consistent, and auditable over the life of the building.
We help by:
-
Providing a clear structure for handover-ready information
-
Preserving the completed handover record post-completion
-
Ensuring evidence remains intact and traceable after occupation
-
Anchoring the record to the building for long-term reference
-
Providing role-based access where required, without transferring accountability
Once handed over, accountability sits with the appropriate dutyholder.
A handover record you can stand behind, even after you leave site.
What the handover record typically includes
In practice, the handover-ready record commonly includes:
-
Health and safety file content
-
Quality assurance records, including inspection and test plans (ITPs) and results
-
Photo records evidencing construction progress and key installation stages
Key Features for Principal Contractors
-
Structured handover-ready information framework
-
Independent post-completion audit record
-
Clear evidence organisation for QA and compliance
-
Photo record preservation
-

Role-based access after handover
It is not about adding admin. It is about leaving site with a defensible handover record you can stand behind if challenged.
