High-Rise & Deep Excavations
Tall buildings and complex basements push ground engineering to its limits. We deliver certainty in challenging conditions, enabling projects to rise safely from the ground up.
CHALLENGES
Common Challenges
in High Rise
& Deep Excavations
High-rise towers and deep basements intensify ground risks—variable soils, groundwater inflows, neighbour impacts, and complex retention in tight sites—demanding meticulous planning and evidence-based decisions at every stage.
1.
Settlement Risks in Variable Soils
Tower loads amplify minor soil variability. We characterise strata early and design foundations/raft improvements to control total and differential settlement.
2.
Groundwater Inflows During Deep Excavation
Unmanaged inflows drive delay and cost. We model groundwater behaviour, design dewatering systems, and protect adjacent assets from drawdown.
3.
Adjacent Building Stability and Vibration Control
Basement works can impact sensitive neighbours. We predict ground movements, set trigger levels, and specify vibration limits and monitoring to keep façades and services safe.
4.
Tight sites, utilities, and deep cuts need the right system. We design anchored/strutted walls, sequenced excavation, and temporary works that fit the program and the site.
