Detailed Risk Assessment

The detailed risk assessment is site specific and considers in depth, the potential risk posed by UXO. The detailed risk assessment process enables us to estimate the likelihood of a UXO hazard being realised at a particular site, by considering the type of development being proposed and the construction methods to be employed. 

Similarly to the preliminary risk assessment, the detailed version is based on historical information regarding site location, previous site development, wartime bombing records and military history. The detailed risk assessment considers these areas in more detail and further considers site specific geology and ground conditions to assess the depth to which an unexploded bomb may have penetrated. 

Information for the detailed risk assessment is gathered from a variety of sources including local authority and national archives, bomb disposal team records, the national geological survey and is supplemented by information held by Fellows in our own archive.  

The detailed risk assessment is carried out by a UXO specialist at Fellows, supplemented by specialist geophysics knowledge and historical researchers.
