NORWEST HOLST Soil Engineering is making a bid to strengthen its position in overwater ground investigations with a string of high profile contracts.
It currently has a platform in central London on the River Thames at the site of the proposed Millennium footbridge between Blackfriars and Southwark bridges, while a second platform is working on an inter-tidal investigation for sea defences at Clacton, Essex.
These contracts follow work in the Thames at Greenwich Reach and the Millennium Dome, where a jack-up rig was used to obtain information on the stability of dock walls. To achieve this, the mast of a trailer-mounted rotary rig was turned through 90degrees, and cores of the wall masonry taken through the full 2m thickness of the structure.
According to business development manager Mike Newton 'overwater work is not new for the company, and it is hoped these high profile contracts will help re-establish its position in this sector'.
