Digital handover
Structure as-builts, manuals, certificates, warranties, tests, photos and location data.
B3 Nexus · Living Digital Twin
Keep the asset digitally alive after practical completion.
The Nexus Living Twin continues the engineering model into operations, connecting design intent, installed equipment, commissioning, inspections, maintenance, sensor data and lifecycle history.
Quick answer
What makes a digital twin “living”?
The project does not digitally disappear at handover. The completed asset retains structured information that can be updated as equipment is inspected, maintained, repaired and monitored through its operating life.
- Design intent and as-built models
- Asset registers, serial numbers and warranties
- Commissioning and inspection records
- IoT and sensor data
- Maintenance, faults, repairs and lifecycle history
Big Three innovation model
From build-and-leave to design, build, digitise, monitor and maintain.
Nexus carries forward the information generated during design and construction so that maintainable assets have a persistent digital identity. A pump, bridge component, electrical panel or treatment module can retain drawings, manufacturer information, commissioning data, inspection history, maintenance requirements and condition information.
Structured digital handover supports QR or NFC asset passports, allowing authorised users to move from a physical asset to its digital record. Sensor readings become part of the asset history rather than a separate technology silo.
Connected capabilities
How this fits into the Big Three delivery model.
Each capability strengthens engineering decisions, construction execution, evidence and lifecycle value across the project lifecycle.
Asset passports
Give maintainable assets persistent identifiers linked to their engineering and lifecycle information.
Sensors & IoT
Connect flow, pressure, strain, vibration, energy, water and environmental data to the asset record.
Maintenance history
Keep inspections, faults, repairs, work orders and condition information connected to the asset.
Operational performance
Compare expected and observed performance to support engineering and maintenance decisions.
Lifecycle intelligence
Build a lifecycle history that supports resilience, renewal and intervention planning.

Frequently asked questions
Practical answers about how Big Three Engineering connects digital engineering with physical delivery.
Is a digital twin just a 3D model?
No. A living digital twin connects the model or digital representation with asset identity, installed information, commissioning, inspection, maintenance, condition and operational data.
What can an asset passport contain?
It can include equipment identity, manufacturer, serial number, installation date, design duty, drawings, warranty, inspections, maintenance, sensor data and current condition.
How do sensors strengthen the Living Twin?
Sensors connect live operating conditions such as flow, pressure, vibration, energy, water and environmental performance to the asset’s digital history.
How does lifecycle intelligence support maintenance?
Lifecycle intelligence connects condition, inspections, faults, work orders and performance history so maintenance teams can identify priorities earlier and plan interventions with better information.
