A client is saved time and money on foundation design, thanks to new advice following a previous geological oversight.
The client was a property developer based in the south-east of England.
Ground & Water’s Preliminary Assessment was that the “relic alluvial soils” had been misidentified and they may well have been Weald Clay Formation deposits. Additional investigation was required to attempt to delineate the spread of the alluvial soils and to determine the presence or otherwise of reworked soils of low bearing capacity.
Ground & Water was asked to review a recommendation given to a client, following a previous site investigation undertaken by a third party. The client was planning to build a large residential development on a site underlain by the Weald Clay Formation. The previous investigation highlighted areas of concern for foundation design, indicating there was a layer of “relic alluvial soil”, meaning a minimum foundation depth of ~2.50m bgl was required. This would have added significantly to the cost of the development and build time.
