FONDEDILE Foundations is in the middle of a huge contract to underpin an historic building in south east London with 30km of mini piling.
The listed Grand Store at The Royal Arsenal at Woolwich was built in the early 19th century and formerly owned by the Ministry of Defence. The complex' six main buildings had fallen into disrepair, with some suffering significant settlement due to failure of the original timber pile foundations .
Government regeneration agency English Partnerships is now tackling the site. The project team includes Pell Frischmann, Llewelyn Davies, Gardiner & Theobold plus Fondedile, which is using its proprietary Pali Radice mini piling system to install mini piles through the old found- ations. The piles are permanently bonded with the existing foundations and founded in the underlying sand and gravel to between 15m and 20m depth.
Some 1,800 raking and vertical Pali Radice piles - equivalent to 30km of piling - will support 1,400m of footings and 172 internal columns. Six test piles were installed to check suitability.
With 100 piles going in every week, Fondedile expects to finish the 34 week programme ahead of schedule.
