Unmanned Systems Vs. Traditional Methods

Traditional inspection methods often rely on scaffolding, cherry pickers, rope access, or manual entry into hazardous environments. Drone technology is revolutionising the way critical assets are inspected across industries. 

Enhanced Safety

Minimal Disruption to Operations

PDRA 01 Authorisation

  • Eliminate the need for Working at Height or Confined Space Access Teams – No scaffolding, ladders, or rope access required.
  • Keep personnel on the ground – Reduce the risk to staff, contractors, and the public.
  • Access hard to reach or hazardous areas – Safely inspect rooftops, towers, facades, unstable structures and confined spaces.
  • Inspect aging or unstable structures – Close-up visuals of compromised infrastructure without endangering workers.
  • Support compliance with H&S and CDM regulations – Demonstrate proactive safety measures during maintenance and asset management.
  • Operational Authorisations - Enhanced authorisations allow NC4 Vertical to conduct operations with unmanned aircraft (UA) between 250g and 25kg in residential, commercial, industrial and recreational areas.

  • No downtime or site shutdowns – Inspections can often be carried out while your business operates as normal.
  • Fast deployment and rapid data collection – Conduct inspections quickly during off-peak hours or within short access windows.
  • Avoid bulky (and expensive!) equipment – No scaffolding, MEWPs, or rigging means less disruption to the surrounding environment, workflow and your overheads.
  • Quiet, low-impact inspections – Drones are far less disruptive than traditional inspection methods.

Drone mission planning summary

  • Save time and resources –  Cover large or complex structures in a fraction of the time of traditional methods.
  • Collect precise, georeferenced data – High-resolution visual, thermal, and 3D modelling to support asset management, defect analysis and enable accurate reporting.
  • Quick turnaround on actionable data – High-resolution images, video, and thermal/multispectral data delivered fast.
  • Built-in repeatability – Schedule regular, consistent inspections to monitor changes over time with minimal planning.
  • Ideal for documentation – Use for insurance claims, contractor engagement, and before/after comparisons.
