More than 30,000 tonnes of bombs were dropped on Britain during World War II. Combined with munitions from World War I and MoD firing ranges the risk of encountering Unexploded Ordnance (UXO) has to be a consideration during development. Egniol can help manage the risks from this legacy.
Guidance and Risk
Guidance released by CIRIA in 2009 estimated that 15,000 items ranging from unexploded bombs, grenades and small mortar rounds were unearthed on UK construction sites between 2006 and 2008. The Aston expressway in Birmingham was closed in 2016 for a time and nearby houses evacuated after the discovery of a bomb containing 132kg of high explosive. More recently, London City Airport was closed due to the discovery of a WWII bomb in the Thames. These events have a major impact on Health and Safety, project costs and programme and a structured, risk based approach is needed to manage and mitigate them robustly.
Egniol have a wealth of experience in dealing with these sites. UXO is considered within a Phase I study where UXO and bomb risk maps are consulted, particularly for the heavily targeted areas during WWII (London, Liverpool, Manchester, Glasgow, etc). If deemed to be at risk we would then consult with specialist organisations to arrange further information to be gathered and a risk management strategy to be drafted. This often involves specialist personnel in site works to continuously monitor excavation practices and utilise non-intrusive surveying techniques to detect UXO underground. Having clarity in the approach makes for a safe and cost-effective project.
