A Ground Investigation was required for a high-profile mixed-use development in the heart of Fulham, transforming a redundant gasworks site into a high-quality new urban quarter. The development comprises almost 2000 new homes with a range of complementary uses across 15 new buildings up to 37 storeys in height. At the heart of the master plan, a new square will provide an enhanced setting for two Grade-II listed buildings and a listed war memorial, whilst a new urban park also provides much-needed amenity space for the wider community and a setting for the Grade-II listed Gasholder No. 2.
The drilling to depth required techniques capable of drilling through the whole London Sequence including River Terrace Gravels, London Clay, the Lambeth Group and into the top of the chalk. Whilst drilling through the London Clay certain marker beds were found including the pebble beds of the Upnor and Harwich Formations and fossil beds within the London Clay. This information was fed directly by the CCGI Engineer to the supervising Engineer who then specified site-specific in-situ testing regimes, sampling and installations.
The works were carried out using in-house drilling rigs including our cable percussion rig, multi-purpose rigs, hand-held windowless sampling equipment, and a JCB 3CX. All works were supervised on a full-time basis by suitably qualified Engineering Geologists, with logging carried out to BS5930: 2015+A1:2020 and BS EN ISO 14688 [Parts 1 and 2].
