After GeoCon’s success on the Gwynt-y-Mor on shore cable route geotechnical site investigation on behalf of a large multi national contractor, GeoCon were invited to supervise a geotechnical site investigation at Barkby Beach, Prestatyn North Wales. The geotechnical site investigation included four boreholes to faciliate the installation of plastic casing for a subsequent geophysical survey to establish the location and depth of an existing sheet piled wall.
The site was located on the beach and the sheet piled wall was anticipated to be located at the bottom of the existing sea defense structure.
The location of the sheet piled wall was required in order to design the input route of an offshore cable coming over from Ireland to provide future electricity to parts of North Wales.
GeoCon successfully undertake a Phase I and Phase II site investigation on land at 1A Wilton Way, Islington London.
The results of the Phase I indicate that the site has remained as a back garden to a residential property since the earliest historical maps in 1893 for the area.
The local authority building control department specified that they would accept some basic testing in two locations at the site.
Chemical testing results indicate elevated lead levels in the reworked topsoil beneath the site. The proposed development will completely cover the site in hardstanding leaving no proposed areas of landscaping.
Therefore the pathway between the lead contamination source and the human end users is removed.
The site was deemed suitable for use.
