The site investigation started Thursday, Feb 16,  and took about 12 days. It involved the engineering team Kim and Gareth from TBedford Drilling. They dug a number of 20-30 metres deep installing four or five 6 inch boreholes with measurement devices. The purpose of this work is to test for any contamination, identify precise soil conditions at various depths, and identify the level of the water table. The work was done using a mini excavator and a “tripod” drilling rig and not surprisingly we found a lot of London Clay that we have kept to be prepared for use by artist's projects.
