Igne conducted over 3,300 intrusive UXO surveys at London's Royal Albert Dock, to ensure the proposed pile foundation locations were free from WWII ordnance. The Royal Albert Dock site in London is considered to be a high risk location in terms of the likelihood of encountering unexploded ordnance (UXO) on site, dating back to WWII.

This publication will facilitate coordination, integration, and force protection requirements regarding UXO during joint exercises, contingencies, or other operations. It also identifies functions and responsibilities for planning, reporting, tracking, and clearing UXO, while minimizing the impact of UXO on the mission.

UXO detection can be done with many different geophysical techniques depending on suspected target properties, soil properties and potential external disturbances. Geotechnical measurements help UXO detection work by potentially reducing the detection volume. UXO detection is often perceived as an unwanted delay of the original project work.

UXO During World War II, Europe was severely bombed and it is estimated that 10% of the dropped bombs did not explode. A large portion of this unexploded ordnance (UXO) is still present in the underground and can be hazardous during groundwork, such as digging, drilling, foundation works, piling, dredging, etc.

On projects where a risk of encountering UXO/UXB has been assessed, and where deep intrusive groundworks such as piled foundations are planned (more than 4 meters below ground level) – an Intrusive Magnetometer Survey will provide detection and clearance ahead of individual pile locations, window samples and boreholes.

On sites where a risk of encountering deep buried unexploded bombs (UXBs) has been assessed, and where piled foundations are planned, we can conduct an Intrusive UXO Survey to provide clearance ahead of individual pile locations, clusters and boreholes.

The assessment of UXO risk is a measure of probability of encounter and consequence of encounter; the former being a function of the identified hazard and proposed development methodology; the latter being a function of the type of hazard and the proximity of personnel (and/or other ‘sensitive receptors’, such as equipment) to the hazard ...

What is a UXO Survey? A UXO Survey is a means of proactive UXO Risk Mitigation undertaken to reduce the risk of encountering unexploded ordnance on a parcel of land, or marine environment, to as low as reasonably practicable (ALARP).

Risks from UXO during development are commonly greater than during investigation due to the increased number and depth penetrations, e.g. piles at close spacing. Early identification and appropriate UXO risk management benefits all projects in the longer term.

On construction sites where a desktop or non-intrusive survey has identified a risk of encountering deep buried unexploded ordnance (UXO), and where intrusive works such as piled foundations are planned, intrusive surveys can enable detection and clearance of the risk ahead of works.
