  • Construction Sequence Development – Tailored strategies to minimise ground movements and protect adjacent assets during construction.
  • Basement and Deep Excavation Engineering – Technical guidance for deep excavations, often in urban settings, balancing safety, performance, and constructability.
  • Ground Movement Risk Mitigation – Analysis and recommendations to safeguard surrounding structures in dense urban environments.
  • Project Collaboration and Advisory – Close coordination with design teams to ensure collaboration throughout construction.
  • Award-Winning Project Experience – Proven track record on high-profile developments including Cannon Street Station, Infinity Bridge, and Intesa Sanpaolo Tower in Turin, Italy.
