Restricted Access and Confined Space Surveys

What are restricted access and confined space surveys?

These surveys evaluate and map environments that are difficult or hazardous for personnel to access directly, such as sewers, tanks, ducts, pipelines, derelict or dilapidated buildings and industrial vessels. By deploying advanced remote platforms (Elios 3 and ROVIEW 2),  our focus is on both operator safety and data quality in every survey.

Why are these surveys important?

Restricted access and confined space surveys are crucial for capturing data essential to assessing structural integrity, identifying potential hazards and planning maintenance or rescue operations, thereby ensuring the safety and longevity of critical infrastructure.

Elios 3 survey-grade UAV

• High-resolution photogrammetry and LiDAR payloads
• Integrated safety cage and LED illumination for confined spaces
• Real-time video link for live inspection and navigation
• Compact design enabling rapid deployment
• On-board explosive gas sensor

ROVIEW 2 tetherless crawler

• Climbing, crawling and swimming in multiple confined spaces
• 360° pan-tilt-zoom camera and LED ring lighting
• Wireless control for unrestricted manoeuvring
• Modular sensor integration for depth, humidity and more
• Can be equipped with mobile scanning solutions (LiDAR), atmospheric testing equipment, etc.

ABM-90 pipe and duct mapping

• Adaptable wheelsets for mapping sewers, rising mains, pipelines and ducts
• Changeable wheelsets for stability in varying diameters
• 4K camera integration delivering detailed imagery
• Seamless georeferencing for accurate integration into site plans

Proofing and georeferencing

All survey data captured by the Elios 3 UAV, ROVIEW 2 crawler and ABM-90 is rigorously checked, proofed and, where necessary, georeferenced using our additional surveying methods.

This ensures:

• Seamless integration with existing site coordinates
• Sub-centimetre positional accuracy for deliverables
• Reliable, actionable 3D models and point clouds
