UXO Risk Assessment_

Acquiring a UXO risk assessment for your site is the first step towards your UXO risk management plan. Using historical research methods, we place your site in its military context, analysing the impacts of allied and enemy action alongside any post-war developments. With your project scope in mind, we will then provide you with a bespoke UXO report, complete with actionable recommendations, aligning perfectly with your project’s scope.

Preliminary Unexploded Ordnance (UXO) Risk Assessment_

A Preliminary UXO Risk Assessment is a qualitative screening exercise to assess the likelihood of discovering UXO on your project. Completed by our experienced research team, we take an overview of your proposed site and investigate any military activity on or near your land. We use this information to assess the UXO risk on your site, providing you with a risk rating and any recommended further action. If you already know your site is a former military site, you’ll need a Detailed Unexploded Ordnance (UXO) Risk Assessment.

The majority of sites in the UK are classed as low risk. With a 24-hour turnaround a Preliminary UXO Risk Assessment is the most cost-effective and fastest way of discounting UXO risks for your site. We never use automated systems to generate our risk assessments, instead we rely on primary and secondary historical sources and expert evaluation to keep your projects moving along.

If your site is a former military site then you will need to start the process with this type of assessment – a Detailed UXO Risk Assessment. Although most parts of the UK will return a low UXO risk rating, sometimes further analysis is needed. One benefit of this further analysis is zoning your site, as some areas may have higher risks than others – reducing your overall costs.  

Applying the Source, Pathway, Receptor, Consequence (SPRC) Risk Model, we evaluate the range of ways WWI and WWII action could have led to UXO contamination and how modern construction methods, including human factors affect the likelihood of encountering UXO. 

A Detailed UXO Risk Assessment uses additional sources of information to calculate critical factors, including estimated bomb penetration depths and the types of UXO contamination present on your site. This approach involves extensive research and analysis, giving you a more granular look at UXO risk mitigation options.

An Expedited Detailed Risk Assessment (EDRA) is an alternative to our Detailed UXO Risk Assessments. It is still considered a stage 2 UXO risk assessment and undergoes the same extensive research process, but it has a faster turnaround time and contains more concise information which makes it easier and quicker to understand.

In an EDRA, all site-specific information is front and centre. Background information and UXO industry context is provided in a separate supplementary document, and figures such as images and maps are not included (unless you request them separately).

Quantitative Unexploded Ordnance (UXO) Risk Assessment_

By considering bombing density and cubic metres of ground disturbance, we can calculate the likelihood of you encountering UXO on your site. Using novel mathematical models, we are able to provide you with a probabilistic rating for your site, quite literally a % chance of you finding UXO on site.

Not happy with the assessment your site has been given by another UXO specialist?

We can evaluate their work by looking at their sources and analysis. From our experience the quality of research across the industry can be highly variable. We add confidence to your UXO risk assessments and provide you with more realistic and appropriate mitigation services.
