Van Elle goes deeper at Bow Green: CFA piling lessons for foundation engineers
Reviewed by Tom Sullivan

30 Second Briefing
Van Elle’s Rock & Alluvium has installed 594 continuous flight auger piles up to 40m deep and 400–750mm in diameter at Berkeley’s Bow Green development in east London, its deepest CFA work to date and among the deepest in the UK. Specialist rigs including a Llamada P240 and Soilmec SR-45 handled the main piling, with a Klemm 709 used in restricted-access zones between live railway lines, Tower Hamlets Cemetery Park and Bow Common Lane. The foundations will support four residential blocks within a wider scheme of up to 1,764 homes in buildings up to 19 storeys.
Technical Brief
- Nine-week piling campaign required concurrent operation of multiple rigs to meet programme constraints.
- Llamada P240 and Soilmec SR-45 selected to deliver high torque and crowd for deep CFA penetration.
- Klemm 709 used where access was restricted by live railway, cemetery park boundary and Bow Common Lane.
- Up to 19-storey building heights drive high axial and lateral load demands on the deep pile group.
- Around one hectare of landscaped green space will load underlying ground lightly, contrasting with adjacent tower foundations.
Our Take
The Bow Green piling work in London gives Van Elle a high-profile UK reference project just as Strabag UK moves to acquire the business for £58.8M, suggesting Strabag will inherit stronger credentials in deep CFA piling for dense urban sites.
In our database of 806 Infrastructure stories, Van Elle appears frequently in rail and industrial foundations; this 40 m CFA record broadens its track record towards high-rise residential schemes up to 19 storeys in constrained city locations.
