A builder had commenced excavating the trenches for a large side and rear single-storey extension but had encountered soft ground conditions up to 3.0m below ground level. The scheme proposed was to install 10 No. 150mm diameter driven steel cased piles to a depth of 6.0m, together with 21Lm of a 450mm wide by 300mm deep reinforced concrete ground beam. Works were completed in 4 days.
