Ordtek consults pertinent datasets, including historical records of the area, and then compare findings against the criteria set out in the CIRIA guidance document and to discharge the Client’s obligation under the Health and Safety Act. This process allows Ordtek to determine whether a justifiable hazard from UXO exists.

Stage One – Preliminary UXO Risk Assessment

An initial screening where the UXO hazard is not known or the activity is deemed to have a small scale impact. Using key records from a number of sources Ordtek can accurately build up a history of hazards and their proximity to a project.

Stage Two – Detailed UXO Risk Assessment

Where there is a known UXO hazard, for example a legacy of bombing in the area or where the site is close to airfields, a detailed risk assessment is required. Within a detailed risk assessment, the risk is identified and assessed against the probability of encounter and consequence of detonation, taking into account the expected activities on site. Using pertinent records from a number of sources Ordtek can accurately build up a history of hazards and their proximity to a project. Procedures are outlined on how the site-specific UXO risk can be reduced to ALARP across the whole lifecycle of the project and identifying any residual risks that may remain. The risk mitigation section will advise a scope that is both relevant to the magnitude of work planned on site and proportionate to the cost to lower the risk.
