Power Station, St Lucia, Windward Islands Non-engineered back-filling of a tropical valley was investigated between 1988-91 for the new Cul-de-Sac power station and substations. Following detailed seismic risk and reciprocating vibrations assessment, compaction by vibro-replacement was chosen, supervised and a stiff foundation raft constructed. Recent hillside instability was analysed and the critical
Combe Down, Bath In 1988-89 open-cast quarries and shallow stone mines at The Brow were investigated by trenching and rock probing for several large detached houses. Successful stabilisation was achieved by jack-hammering out the thin roof cover, crushing the rocky spoil and consolidating with vibro-replacement stone columns. Raft foundations were subsequently adopted.
Newquay, Cornwall Co-ordinating geotechnical aspects of Cliff Road leisure centre redevelopment at cliff top, with 5m back cantilever, between 1987-1992. Managing cliff stability works for Restormel Borough Council, including unstable rock anchoring, break-up and removal, and constructing reinforced, drained, sprayed concrete protection. Return visits in 2000, 2008, and 2015 to confirm ongoing stability
GSZ Superhighway, Southern China Developing appropriate linkage between British Standard ground investigation techniques and equipment and the equivalent available Chinese methodologies. Completing detailed rock core assessment at bridge pier locations, interpreting geological profiles and conceiving likely pile design criteria.
