Located in London’s prestigious Kensington area, this project involved the multi-million pound refurbishments of 98 luxury apartments. We were contacted to review the feasibility of extending downwards three existing lift shafts as the current lifts stopped at ground level and needed to be extended to basement level.


The original building was constructed on a 1200 mm thick pile raft which had been constructed in the 1980s. This meant indicative records did exist but could not be fully relied on.

Temporary Works: Geostructural Solutions

We were asked to find a solution to allow the existing RC raft to be broken out in three locations while maintaining the structural integrity of the existing multistorey structure. In-house designs were undertaken to analyse the structure at each stage of the process.

It was also essential that the existing reinforcement was maintained for continuity into the new shafts. Given the density of the existing reinforcement, retrofit couplers weren’t an option. To facilitate this, the concrete was removed using a combination of hydrodemolition and conventional diamond coring.

Hydraulic Jacking: Temporary Support

The sequential demolition via non-percussive techniques required sacrificial steel props to be preloaded and installed to support the existing 10-storey lift shaft. By preloading the props, which were founded on RC pads in the terrace gravels, we were able to reduce the settlement experienced to an imperceivable level.

The lift pits were reconstructed from waterproof concrete to ensure that no long-term waterproofing issues occurred. Overall, we provided the client with a programme saving of over six months on the original scheme.
