About Us
S.I UXO is the fruition of decades of renowned UXO engineering knowledge and experience underpinned by an ambition to transform the industry.
S.I UXO is an established UK UXO risk management contractor founded by former military EOD specialists and geotechnical engineers, with leadership bringing 50+ years of combined field experience and an ambition to
“transform the industry”.
The business delivers end-to-end UXO risk mitigation for land and marine developments, working from early planning through to on-site delivery and post-clearance outputs, aligned to CIRIA C681 and industry best practice.
S.I UXO provides a full-spectrum UXO risk management service aligned with CIRIA C681 and UK planning best
practice, supporting construction, infrastructure, marine, and energy projects from feasibility through to intrusive
works and final sign-off.
At the pre-construction and planning stage, S.I UXO delivers Preliminary and Detailed UXO Risk Assessments founded on rigorous historical research, including detailed wartime bombing analysis, military land-use records, aerial photographic interpretation, and site-specific geotechnical correlation. Assessments are evidence-led, defensible, and proportionate, enabling clients, designers, and regulators to make informed decisions on risk, scope, and cost control.
For risk mitigation and verification, S.I UXO undertakes non-intrusive and intrusive geophysical UXO surveys across land and near-shore environments. Survey methodologies are tailored to ground conditions and development constraints and include walked, towed, and platform-mounted magnetometer arrays, borehole UXO detection, and advanced data processing to discriminate between geological anomalies, ferrous clutter, and genuine UXO-like targets.
A key differentiator is S.I UXO’s tracked CPT-based intrusive detection capability, allowing high-confidence
interrogation of UXO risk in challenging ground conditions where traditional borehole magnetometry or window
sampling may be insufficient. This approach supports deep target detection, improved confidence in unexploded aerial bomb assessment, and direct integration with geotechnical investigation programmes—reducing duplication, programme risk, and overall cost.
During intrusive groundworks, S.I UXO provides UXO watching briefs, engineer supervision, and contractor support, ensuring safe execution of piling, drilling, excavation, and enabling works. Where required, the company deploys controlled excavation techniques, including vacuum assisted methods, to safely expose suspect anomalies while minimising disturbance and risk to personnel and assets.
All operations are underpinned by in-house GIS and geospatial data management, allowing survey outputs, target plots, clearance extents, and residual risk zones to be delivered in CAD-, GIS-, and BIM-compatible formats. This ensures seamless integration with design teams, principal contractors, and client reporting systems.
S.I UXO operates nationally across the UK, with the ability to mobilise rapidly to support time-critical projects,
maintaining a strong emphasis on technical accuracy, regulatory defensibility, and pragmatic risk reduction rather than generic or overly conservative solutions
S.I UXO is a UK-based leader in unexploded ordnance risk management, delivering compliant services for land and marine developments with precision, safety, and integrity.
