Detailed UXO Risk Assessment_
Detailed UXO Risk Assessments are essential for sites on active and former military land or in areas where a potential unexploded ordnance risk has been identified.
At Brimstone UXO, we specialise in delivering comprehensive assessments that enable informed decision-making, giving you peace of mind that you can proceed with your project safely.
What is a Detailed UXO Risk Assessment_
A Detailed UXO Risk Assessment involves a comprehensive investigation into the potential for UXO to be present on a site. This includes in-depth research into historical military activity or enemy action in the area, alongside an assessment of how modern construction methods and human activity may influence the likelihood of encountering unexploded ordnance. The process also identifies the types of ordnance that may be present and the maximum depth at which they could be buried.
Also known as a Stage 2 UXO Risk Assessment or a DRA, this assessment is typically carried out during the planning stages of a project – before any ground investigation or construction takes place.
Our detailed research enables a more granular understanding of the risk, helping you explore mitigation options that are proportionate and cost-effective.
How we create our tailored UXO reports_
Producing a Detailed UXO Risk Assessment at Brimstone is a thorough and methodical process, shaped by years of experience.
Our team has spent the last eight years refining our research processes and risk assessments to deliver clear, reliable, and cost-effective results. Each of our researchers holds a relevant degree and shares a strong interest in historical analysis.
We consult a wide range of historical sources to inform our assessments, including bomb maps, damage records, aerial photography, OS mapping, training records, and military defence plans.
Our in-house library is extensive, but every assessment is bespoke. If we don’t already hold the necessary material, we’ll source it through archive visits, online research, or consultation with local historians.
Once we’ve gathered the evidence, our team assesses the likelihood and potential consequences of UXO being present.
We look closely at factors such as why the site may have been targeted, whether any unexploded bombs could remain undetected, and whether your proposed works are likely to disturb them.
Every Brimstone report goes through an internal quality assurance process to ensure accuracy, clarity, and consistency.
The final report outlines our findings and recommendations in a clear, structured format – providing the guidance you need to decide on the next steps.
Why a Detailed UXO Risk Assessment is Essential for Your Project_
A Detailed UXO Risk Assessment offers significant advantages for many project sites:
UXO contamination can be present across the UK – even in locations you might not expect. A Detailed UXO Risk Assessment gives you a full understanding of the potential risk, helping protect your team, the public, and nearby infrastructure.
While there’s currently no legal requirement to conduct a UXO risk assessment before construction, you are legally obligated to keep workers safe.
The CIRIA C681 guidance is the industry standard for UXO risk management and outlines four stages: Preliminary Risk Assessment, Detailed Risk Assessment, Risk Mitigation, and Implementation. Following this guidance helps reduce the chance of encountering UXO and ensures your project follows best practice.
Identifying potential risks early on helps avoid delays and unexpected costs. Our assessments support better planning and safer decision-making at all stages of a project.
Our reports aim to be as specific and proportionate as possible. If the UXO risk varies across the site, we’ll provide zoning where appropriate. This helps reduce overall costs by focusing mitigation efforts where they are most needed.
Get Faster Results with Our Expedited UXO Risk Assessments_
Brimstone also offers Expedited Detailed UXO Risk Assessments (EDRA), launched in 2023 in response to client feedback.
This version of the assessment still meets the same standard as our full report and follows the same rigorous research process, but is delivered faster and in a more concise format.
In an EDRA, site-specific findings are brought to the forefront, while background detail and contextual information are included separately. Figures such as maps and aerial imagery are omitted from the main report but can be provided on request.
This format has been designed to suit clients who need quicker access to key insights while still benefiting from Brimstone’s usual depth and accuracy.
What to Expect From Your Detailed Risk Assessment_
Once your Detailed UXO Risk Assessment is complete, we’ll provide a bespoke report covering all relevant findings and recommendations.
The report includes a breakdown of site history, potential UXO sources, the types of ordnance that could be present, a summary of key findings, a risk rating, and any recommended next steps. Maps, imagery and data sheets are also included to support our conclusions.
If a risk is identified, we may recommend a UXO survey, designed to detect any buried metallic objects. The type of survey depends on your site characteristics and the nature of your proposed works.
In some cases, we may also recommend on-site UXO supervision, such as a Watching Brief or Borehole Support.
If the risk is considered low, there may be no further mitigation required, allowing you to move forward with confidence.
