Collect evidence with a defined purpose.
A survey can help identify anomalies that may need further investigation. An anomaly is a response in the data; it is not, by itself, confirmation that an explosive item is present. Background conditions, obstructions and the chosen sensing method influence what can be interpreted.
Survey proposals should state the area, required investigation depth, equipment, access assumptions and reporting approach. Drone imagery and LiDAR may help map terrain and surface features, but must not be presented as a general method for detecting buried explosives. Target investigation and any subsequent clearance require separately agreed specialist scopes.
What the scope can include
- An agreed survey objective and coverage plan
- Documented acquisition and interpretation limitations
- Mapped findings or targets within the contracted scope
- Recommendations for further investigation where justified
What we need from you
- UXO assessment and survey objectives
- Site layout, access and surface conditions
- Relevant depths and planned development works
- Existing geophysical or investigation data
Does a survey identify every buried explosive item?
No. Detection and interpretation depend on the method, target characteristics and ground conditions. A report should explain its coverage and limitations, including what the work cannot demonstrate.
