22 Bishopsgate

EXISTING FOUNDATIONS AND BASEMENT STRUCTURE WERE USED AS MUCH AS POSSIBLE FOR THIS PROJECT

22 Bishopsgate was designed with a view to being the tallest building in the City of London, standing at 278 metres. Construction on the site of the previous Pinnacle scheme was halted due to funding issue with the core at 7th floor but the new development proposed to reuse as much of the existing foundations and basement structure as possible. Where the original core was positioned, the existing foundations have sufficient capacity to support part of the new core. For the remainder of the core however, additional foundations were required.

To enable both halves of the core to be slipformed together above ground floor, ByrneLooby were appointed to design a transfer structure between B2 and ground floor to suspend half the core on five columns. This would enable the core to be constructed to level 15 whilst the new foundations were installed below. As a result, some 15-20 weeks would be saved on the overall programme. To gain further programme advantages, ByrneLooby upgraded the original design to provide the capability of constructing to level 22 before the foundations were completed below.

 

STAFF INSIGHT

“Working on 22 Bishopsgate gave me the exciting opportunity to be part of one of the most prestigious construction projects in London. The unique technical and logistical challenges involved in the project have been invaluable in helping me develop as an engineer. I thoroughly enjoyed working alongside the large construction team in a fast paced and dynamic environment to help ensure the successful completion of the project.”
