Arora Hotel, Greenwich Peninsula, London

As part of the development of an 18-storey hotel and a 24-storey apartment tower adjacent to a new ballroom structure, we delivered a piling solution on a heavily contaminated site in Greenwich, located between the London O2 and the River Thames. 

The site’s industrial legacy as a former gasworks facility presented significant environmental and engineering challenges. Contaminated ground conditions and the risk of underground obstructions required a solution that was both technically robust and environmentally responsible. 

We designed and installed approximately 1,800 driven precast concrete piles as a cost-effective alternative to a bored pile solution. This solution meant there was a vast reduction in the quantity of contaminated spoil materials for removal and disposal, aligning with the project’s sustainability goals and minimising disruption on site. 

To mitigate the risk of underground obstructions preventing successful installation of pile foundations, we implemented pile probing to locate and navigate the obstructions, ensuring efficient installation. 

This innovative approach not only delivered substantial cost and carbon savings but also supported the safe and sustainable delivery of a landmark regeneration scheme in one of London’s most dynamic districts.
