Comprehensive UXO Risk Management Services
Desk-based assessments to intrusive clearance, S.I UXO offers complete lifecycle support for UXO risk mitigation in the built and marine environments.
UXO Risk Assessments
We provide Preliminary and Detailed UXO Risk Assessments in accordance with CIRIA C681, identifying potential threats based on historic records, site-specific data, and regional risk modelling.
What It Is:
UXO risk assessments form the critical first step in understanding and managing ordnance threats on a site. These evaluations involve a comprehensive review of historic military activity, including bombing density, munitions manufacturing, land usage and conflict exposure. Our team conducts both Preliminary and Detailed Risk Assessments, offering a layered understanding of threat levels relative to your planned works.
Why It Matters:
Identifying UXO risk early enables project teams to make informed decisions and avoid costly delays or safety incidents. Our assessments are fully compliant with CIRIA C681 and provide the technical foundation required to support planning applications, insurance underwriting and HSE compliance.
Non-Intrusive UXO Surveys
Using advanced magnetometry and geophysical techniques, we deliver high-resolution mapping to detect ferrous anomalies across land and sub-surface environments, ideal for early-stage planning.
What It Is:
Non-intrusive surveys use advanced surface-based detection techniques to scan for subsurface anomalies. Using towed or handheld magnetometers, we map magnetic disturbances across a site without physically disturbing the ground. These surveys are ideal for open land, parks, brownfields, and locations with limited development history.
Why It Matters:
Surface-level anomalies can provide early warning of potential UXO presence. By avoiding unnecessary excavation or delay, non-intrusive surveys offer a fast, cost-effective way to validate lower-risk sites or guide targeted investigations.
Intrusive UXO Surveys
Our in-house Cone Penetration Testing rig enables safe and effective investigation of deep-buried threats, including large air-delivered bombs. This approach is essential for sites with limited surface access or complex geology.
What It Is:
Our Cone Penetration Testing rig delivers deep, high-resolution magnetometer data during ground penetration, reaching depths over 10 metres. The system combines mechanical push capability with in-situ sensor technology to detect buried UXO with exceptional precision.
Why It Matters:
Where deep foundations or piling are required, intrusive survey data is critical. The Cone Penetration Testing rig allows confident clearance of individual pile positions and boreholes, particularly in urban, constrained or historically bombed areas.
UXO Identification & Clearance
We manage the safe excavation, identification, and if required, disposal of UXO in line with MOD and HSE protocols, ensuring minimal disruption to project timelines.
What It Is:
In the event of a suspected UXO, our trained explosive ordnance disposal (EOD) teams conduct controlled identification and where necessary, safe removal or neutralisation of the item. We follow HSE and MoD-approved procedures to handle ordnance safely.
Why It Matters:
UXO discoveries during construction can lead to emergency response scenarios, evacuation, and significant disruption. Having the capability to respond quickly, assess accurately and dispose of ordnance professionally protects life, reputation and investment.
Borehole Clearance & Pile Positioning
We offer intrusive borehole clearance services, confirming the absence of UXO at key foundation points with absolute certainty.
What It Is:
This service involves targeted intrusive testing to confirm that locations or boreholes are free from unexploded ordnance. Techniques include magnetometer logging, borehole inspection and supervised probing at specific coordinates.
Why It Matters:
Major construction activity often requires deep ground disturbance. Verifying that key structural points are UXO-free ensures structural integrity, reduces liability, and prevents costly delays due to unexpected finds during critical construction phases.
Consultancy & On-Site Supervision
Our consultants support risk management planning, regulatory compliance, and on-site safety procedures, offering pragmatic guidance throughout your project lifecycle.
What It Is:
Our consultancy services cover project planning, technical reporting, and on-site UXO supervision. We provide watching briefs, toolbox talks, and strategic risk mitigation guidance from concept to completion.
Why It Matters:
UXO risk doesn’t end with assessment. Continuous supervision and informed consultancy help teams maintain safety and compliance during excavation, piling or demolition activities, ensuring proactive risk control throughout.
