FUGRO ENGINEERING Services is preparing an engineering report for the foundations of a Berkeley Homes' development on the site of a former television studios in Southwark, south London.
The construction looks likely to involve deep, large diameter piles with column loads up to 5000kPa.
To gauge the bearing capacity of the soils and heave properties of the London Clay, FES has put down five boreholes to depths of 45m, taking samples at 1-3m intervals.
Standpipes were installed in boreholes to monitor groundwater levels within the water bearing Terrace Deposits, Harwich Formation and Thanet Sand.
Boreholes were constructed during demolition work.
Drillers encountered made ground with former basements and foundations.
Berkeley's proposals for the site include a 26-storey residential block, shops, a supermarket and underground parking.
