Who Inspection Services Are For
Infrastructure Operators
Manage critical assets in tunnels, sewers, confined spaces, and industrial facilities.
→ Needs reliable inspection data from environments that are unsafe or inaccessible for manual survey.
Utilities
Operate and maintain water, gas, and energy networks across distributed sites.
→ Needs consistent spatial records to track asset condition and plan maintenance across infrastructure portfolios.
Industrial Operators
Run operations in environments where access is restricted, hazardous, or constrained.
→ Needs pre-deployment assessment and ongoing condition monitoring without exposing personnel to risk.
Long-Term Value
Each deployment builds a growing record of spatial data. Over time, this becomes a strategic asset for infrastructure management.
Maintain digital records
Every deployment produces structured spatial data. Over time, these records form a comprehensive digital archive of infrastructure condition.
Track infrastructure changes
Compare spatial datasets across inspections to identify deterioration, movement, or structural change — supporting evidence-based decision-making.
Support maintenance planning
Use spatial records and condition data to prioritise interventions, justify expenditure, and plan works with accurate environment intelligence.
How It Works
From site assessment to structured spatial data in three stages.
Scope
Define the Environment
Assess the deployment site, identify constraints, and determine the inspection requirements — access conditions, data needs, and operational objectives.
Deploy
Inspect with Unmanned Systems
Integrated unmanned systems capture video, LiDAR, and spatial data in environments where manual access is unsafe, impractical, or impossible.
Deliver
Structured Spatial Data
Captured data is processed into navigable 3D environments via HALO — providing measurable records, video context, and actionable infrastructure insight.
Powered by an Integrated System
Inspection services are delivered using our integrated technology stack. Each product strengthens the deployment.
HALO
Every inspection produces spatial data that feeds into HALO for 3D visualisation, measurement, and long-term infrastructure tracking.
LLRC-1
Provides reliable real-time video during deployments in constrained environments where standard links degrade or fail.
Radio Visualiser
Monitors the RF network supporting each deployment, ensuring communications remain stable throughout the inspection.
