<strong>Geotechnical</strong> <strong>Desk</strong> <strong>Study</strong><br />
It is proposed that the following works are carried out:<br />
• A Phase 1 contamination assessment to determine the potential contamination from previous<br />
land uses.<br />
• A ground investigation comprising three boreholes to a depth of around 20m in the area of<br />
the proposed development and around three machine dug trial pits to a depth of 3m along the<br />
area of cracked tarmac near the top of the cutting.<br />
• Investigation of the integrity of the section of the east side retaining wall that could potentially<br />
be retained, as well as the remainder of the existing wall. This proposed investigation should<br />
include a series of horizontal trial cores through the (exposed) face of the retaining wall to<br />
determine the wall geometry and fill material beyond, together with hand dug trial pits at the<br />
base of the wall to expose and confirm the depth of the wall footings.<br />
• Visual investigation of existing drainage routes within the site, to determine manhole<br />
locations, direction/discharge of flow.<br />
