To date this is our biggest job at around £1m for over 300 plots in several phases for Redrow Homes. The site was an old industrial plant with a high risk of obstructions. The easy solution would have been to use expensive steel piles everywhere, but we saved a considerable sum by using precast concrete piles where possible and changing to steel only where we had to. Cast in situ beams were chosen due to their flexibility when piles are unavoidably deflected out of position.
