Ground Investigation in relation to the Keston Ponds Project

Description

The objectives of the ground investigation are: • Characterisation of the embankment dam structures in terms of composition, stratigraphy, and internal condition; • Assessment of seepage pathways, groundwater regime, and hydraulic connectivity between ponds; • Provide geotechnical parameters for the design of foundations for replacement footbridge structures at locations confirmed by the Supervising Engineer. • Characterisation of soils within the proposed river restoration corridor and wetland creation areas; • To monitor the variation in existing groundwater levels within the floodplain prior to restoration works to establish a baseline; • Environmental and waste classification of arisings in support of the earthworks strategy.
