Drone and UAV Survey Safety
Drones are increasingly used on construction sites for topographic surveys, progress photography, structural inspections, and stockpile measurement. Operating a drone on an active construction site brings specific risks from collision with cranes, interference with lifting operations, and the safety of people on the ground below. This talk covers the regulatory requirements and safety controls for drone operations on UK construction sites.
Key Hazards
Drone collision with cranes, MEWPs, or other aerial equipment on site
Injury to workers below from a drone falling due to loss of control
Interference with lifting operations when drones enter crane exclusion zones
Legal prosecution from flying without the correct CAA authorisation
Control Measures
- Ensure the drone pilot holds a valid CAA Flyer ID and Operator ID as a minimum.
- Obtain a specific operational authorisation if flying within restricted areas or near people.
- Coordinate all drone flights with the site manager, crane operators, and lifting supervisors.
- Establish a ground exclusion zone beneath the flight path to protect workers from a falling drone.
- Do not fly drones within 50 metres of any active crane or lifting operation without written approval.
- Check weather conditions including wind speed, rain, and visibility before every flight.
- Maintain visual line of sight with the drone at all times during the flight operation.
- Brief all site operatives on the planned drone flight time and location before the flight begins.
- Carry out a pre-flight checklist including battery charge, propeller condition, and GPS signal strength.
Remember
- The drone pilot must hold valid CAA Flyer ID and Operator ID before any flight
- Coordinate all flights with the site manager and crane operators before taking off
- Maintain visual line of sight with the drone at all times during the flight
- Establish a ground exclusion zone beneath the flight path to protect workers below
- Do not fly within 50 metres of any active crane or lifting operation without approval
Applicable Legislation: Air Navigation Order 2016 · CAA UAS Regulations (UK) · CDM 2015 · Health and Safety at Work etc. Act 1974
