Soil/ Geotechnical

Our soil services start with detailed subsurface investigations and site classifications in line with AS 2870. Every bore log, DCP result and probe reading is recorded in our central database. With experience nationwide, we deliver highly quality reporting.

Using mechanical drill rigs capable of drilling down to 8m, alongside probes and DCP testing, we accurately map soil profiles. We collect lab samples and conduct on-site compaction checks to confirm earthworks compliance. Survey data like slab heights and AHD links are integrated directly into our geotech models, reducing rework and producing quick turnarounds on reporting. 

To support structural design loads and durability, we deliver wind-rating reports to AS 4055, detailed wind analyses per AS 1170 and snow-loading assessments tailored to local climate extremes. Corrosive-durability ratings to AS 3700 and salinity testing inform material selection and drainage strategies to mitigate long-term deterioration. BMO and LCA services reduce risk on everything from subdivisions to critical infrastructure. As part of our housing team, we offer true end-to-end services with in-house engineering, cutting costs and speeding up delivery.

Soil services we offer:

  • Site classification reports to AS2870
  • Drilling down to 8m
  • Dynamic cone penetrometer testing and reporting (DCP)
  • Laboratory sampling (NATA accredited laboratory)
  • Assessment of compaction reports

Utilising state-of-the-art technology, including drones and 3D laser scanners, coupled with advanced software and digital platforms, we ensure rapid data capture, seamless collaboration and high accuracy. Our scalable model and integrated approach with geotechnical and engineering teams help reduce delays, accelerate approvals and support compliance throughout the build cycle.

Construction Stage Services (CSS)

Our CSS team supports builders during construction—resolving issues on-site with speed and expertise.

We handle slab rectifications, service clashes, design tweaks, and compliance concerns. With in-depth knowledge of the original designs, our engineers deliver code-compliant, constructable solutions that minimise delays.

Working closely with supervisors and trades—remotely or on-site—we provide practical guidance and hands-on help. Whether it’s a quick fix or major remediation, we act fast to keep projects moving.

Our engineers often resolve the same designs they created, closing the loop and improving outcomes across builds.

  • Slab rectification, reinstatement, and cut-through redesign
  • Re-routing or fixing misplaced services (e.g., pipes in slabs)
  • Modifications for penetrations through structural elements
  • Redesign of elements to address on-site architectural constraints
  • Temporary propping and structural support solutions
  • Troubleshooting compliance issues raised by surveyors or certifiers
  • Remote assessments using site photos, videos, and dimensions
