6 Alpha Associates offer unique UXO risk mitigation services which comply with the CIRIA C681 requirements and allow construction related professionals to assess the potential UXO risk to their project sites in the most cost effective and efficient manner.
6 Alpha’s Desktop Studies are undertaken in the form of a UXO threat and risk assessment, which scopes the prospective UXO risks and then designs a suitable and appropriate UXO risk mitigation strategy. This process ensures that the risks to intrusive engineering activities (typically investigation and construction) are reduced to ALARP.
The initial stage of the DTS involves describing (and justifying historically) what sort of UXO might be encountered and where. This is described in writing and depicted in supporting geo-referenced maps defining, where appropriate high explosive and chemical threats.
Drawing upon these findings, we then consider the potential methods of encounter subject to the type of investigative or construction methodology being employed and the energy that is likely to be be generated. The risks of encountering and detonating UXO will be defined as a numerical function of probability and consequence; thus the risk assessment will be based upon numerically scored criteria that offers a semi-quantitative measure of UXO risk.

Benefits
The benefits of our desk top study service include:
- The employment of the most comprehensive and up to date UXO relational data base in the UK;
- Highly accurate georeferenced threat data is supplied in supporting map form;
- Transparent semi-quantitative risk analysis, delivers accuracy as well as wider project benchmarking, with other more conventional project risks;
- Executive management, third party (contractor) and other stakeholder “buy-in” is generated, not only to project threats but also to UXO risks, and risk mitigation planning;
- Corporate governance is not only discharged but also compliant with best practice (CIRIA) and the law.
6 Alpha’s five-stage process (shown below) will help you to uncover the threat of potential UXO and mitigate the risks associated with your site to prevent time and cost delays to your project.
Risk Management Framework for the Construction Industry
Preliminary UXO Threat Assessment
6 Alpha’s Preliminary UXO Threat Assessment provides a background threat report associated with a defined site boundary. Two maps are provided with this type of report: the first is a map depicting high explosive bomb density; and the second is a colour coded map, to scale, depicting the probability of UXO encounter at the site. Each assessment typically takes between 24-48 hours to complete and is aligned with CIRIA C681 guidelines. Please call us on 02033 713 900 for further information.
Price: £155 plus VAT.
Any Study Sites larger than 10 hectares will require additional quotation. Please contact enquiry@6alpha.com or call 02033 713 900 for a formal proposal.
Detailed UXO Threat & Risk Assessment
6 Alpha’s Detailed Threat and Risk Assessment is compliant with stages two and three of CIRIA’s C681 risk management guidelines. This type of report identifies potential UXO threats and also considers amongst other things, ground conditions and any previous site history that may have mitigated the UXO risks. Taking all of these factors into account as well as the proposed engineering intent, a conceptual risk pathway will be established using a semi-quantitative analysis and a bespoke risk mitigation strategy will be designed to ameliorate UXO risks at best value. Our reports are written by experienced UXO research analysts and quality assessed by experienced Explosive Ordnance Disposal (EOD) engineers. Please call us on 02033 713 900 for further information.

UXO Threat Screening Layer
6 Alpha have developed an innovative UXO Threat Screening Layer (TSL) tool, that clearly positions UXO threats and risks in map or chart overlays.
Our UXO TSL thus, zones our clients’ sites into colour-coded areas of elevated and reduced levels of UXO hazard and as such, TSL acts as a unique visual and georeferenced aid to determine – importantly, at the initial and early stages of a project – not only if a UXO threat might be apparent but also to decide if a more formal UXO Threat Assessment is required. 6 Alpha’s TSL therefore affords our clients a number of benefits including:
- Expert Due Diligence: 6 Alpha’s market leading UXO TSL is based on over one million data points, collated within the Azimuth© database – compiled and continually updated for more than 20 years;
- Simplicity and Clarity: TSL provides a clear and interactive visual layer to aid project planning and is compatible with GIS software and Google Earth;
- Speed and Flexibility: the UXO TSL quickly outlines those areas where “No Further Action” is warranted and it therefore provides our clients with flexibility of approach;
- Focussed Resource Management: TSL enables 6 Alpha’s clients to focus their UXO risk management resources in only those areas where there is evidence of a potential UXO hazard;
- Price and Value; TSL is quick and inexpensive to employ;
- Compliance and Safety; 6 Alpha were the lead technical authors for the HSE-endorsed best practice guide for managing UXO risks on and offshore (CIRIA C681 and C754 respectively). The employment of TSL is compliant with risk management best practice standards in general and CIRIA guidance in particular.
