PLACE009 - Osbourne's Pond Reservoir - Ground Investigation

Tender description

Derbyshire County Council requires ground investigation works into one of its reservoirs in the Amber Valley region. The ground investigation (GI) aims to establish the properties of the material within the core of and forming the profile of the existing Osbourne's Pond embankment dam, together with establishing the geology of underlaying natural soils and ground strata at the site of the dam, in particular, the composition and condition of the embankment core (if any), the composition and condition of made ground comprising the (part steeply sloping) downstream face of the dam, the presence/elevation of any seepage profile(s) within the embankment, the existence or otherwise of any piping within the embankment profile which could develop further and lead to future embankment failure (which could in turn lead to breach of the dam), and the composition of any underlaying bedrock, including its elevation, composition and condition. The investigative works constitute a main investigation - No prior desk study or preliminary investigative work is required. Supplemental investigation will be guided by findings from the main investigative site work.
