Site investigation contractor Foundation and Exploration Services (FES) recently finished a land and marine site investigation at Harwich on the east coast of England.

Work was carried out for Mouchel, consultant to Harwich International Port, which wanted information on the sea bed and sub-surface conditions for a new high speed ferry terminal and a berth and offshore moorings about 100m from the existing quay.

FES put down 18 onshore boreholes using a cable percussion rig to varying depths between 5m and 32m. Five cable percussion and rotary boreholes were sunk offshore from a jack-up platform to depths of 40m into the Lower London Tertiary and chalk in up to 10m of water next to a busy shipping lane. Thirteen pressuremeter tests were carried out in four of the holes at various depths from 6m to 40m.
