Benjamin Street | CFA Piling | Secant Wall | Keller UK

Benjamin Street, London

  • The project

Keller were employed to install a combination of 600m diameter hard and soft piles to an average length of 24.5m. A total of 170 linear metres of secant wall were completed in combination with 70No. bearing piles for the foundations and retaining walls for a basement at a new multi-use seven-storey building.

  • The challenge

The greatest risk identified and managed at tender was the restricted working area. The production rate and method of piling was identified in our proposal and these procedures adopted. Close collaboration with the client and the nominated groundworker was developed to ensure programme security.

  • The solution

A simple and clear instruction for the scheme which was clearly briefed to all operatives. The whole site was available for Keller to complete works. The site team planned and executed works accurately and developed a good working relationship with the client.
