Client requirement
Persistent settlement and building tilt required underpinning and overall tilt correction.
Engineering challenge
Collapsible soil, actual pile capacity and ground deformation required analysis of investigation records and observations.
Technical approach
New long, deep anchor-reaction jacked steel pipe piles passed through relevant strata to underpin the foundation. Pile cutting enabled controlled-settlement correction, supported by an implementation monitoring platform.
Project value
The project connected underpinning, tilt correction and monitoring under complex ground conditions.
