Project Overview
About
This Project
KFM Geotech provided construction-phase geotechnical support for a seven-storey residential building over three levels of basement in Castle Hill. The engagement covered groundwater monitoring, piling inspection, piling and crane pad platform assessment, footing assessment by spoon testing, scaffold foundation assessment, and finite element analysis of the shoring wall.

Scope of Works
On-Site Assessment
01
Groundwater Monitoring
Monitoring of groundwater levels through the basement excavation.
02
Piling Inspection
Inspection and recording of pile installation and the conditions encountered at founding level.
03
Piling & Crane Pad Platform Assessment
Assessment of the working platforms supporting the piling rig and crane before the plant was set up.
04
Footing Assessment — Spoon Testing
Spoon testing and inspection of pad footing excavations to confirm the founding material matched the design assumption.

Scaffold foundations assessed on the building perimeter at Castle Hill, NSW
01
Scaffold Foundation Assessment
Assessment of the ground supporting the scaffold foundations around the building perimeter.
02
Finite Element Analysis of Shoring Wall
Finite element modelling of the shoring wall to assess wall behaviour and ground movement through the excavation sequence.
Results
Project Outcomes
Ground-related hold points were cleared as the works progressed, with plant platforms, footings and scaffold foundations each assessed on site before load was applied.
  • Slope stability confirmed — Factor of Safety ≥ 1.5
  • Flexible pavement design approved by certifier
  • Council DA requirements met on first submission
  • Earthworks specification accepted without amendment
  • Retaining wall micropile design parameters delivered on program
  • Construction risk reduced through early site characterisation
