Construction Phase Geotechnical Support
When the excavation opens and conditions don't match the drawings, you need a geotechnical engineer on the phone — or on site — fast. We provide responsive, senior-level construction support that keeps your project on track.
-
On-site supervision of bored piles, screw piles and driven piles — confirming founding conditions, rock socket depth and pile set against the design assumptions. We provide real-time advice and same-day reporting to keep your programme moving.
-
Visual and technical inspection of excavated footing bases, pad foundations, strip footings and raft slabs — confirming bearing material and reporting against the geotechnical design parameters prior to pour.
-
Proof rolling of prepared subgrades and fill platforms to identify soft spots and delineate areas requiring treatment prior to pavement or slab construction. We provide clear pass/fail guidance and remediation advice on the day.
-
Assessment of exposed founding materials — rock quality, weathering profile, defects and bearing capacity — to confirm suitability against design assumptions or advise on revised founding levels.
-
Design and assessment of working platforms for piling rigs and heavy plant operating on soft ground — ensuring safe and stable working conditions without over-designing the platform at the cost of programme efficiency.
-
Ground-condition-specific advice on excavation methodology, dewatering strategy, temporary works and construction sequencing — from the people who investigated the site and understand what's actually in the ground.
-
Classification of excavated soils and fill material as Excavated Natural Material (ENM), Virgin Excavated Natural Material (VENM) or regulated waste — providing the documentation your project needs for legal disposal, reuse or transport of excavated material in NSW.
Geotechnical Services for Private Development
Whether you're a developer progressing a rural subdivision, a builder needing a soil test before laying a slab, or an owner needing a wastewater report for your DA — we provide fast, practical and council-ready geotechnical reports across regional NSW.
-
Development applications across NSW increasingly require a geotechnical investigation report — particularly for sloping sites, flood-affected land, acid sulfate soils areas and rural lots. We scope and deliver the geotechnical reports councils need, without unnecessary delay or overreach.
-
Before you lay a slab, you need to know what you're building on. We conduct soil testing and AS 2870 site classifications for residential lots, dual occupancies and subdivision stages — fast turnaround, clear reports, builder-ready output.
-
Rural and semi-rural blocks require a wastewater assessment — also called an On-Site Sewage Management System (OSSMS) report or land capability assessment for sewage management — before council will approve your DA. We assess soil permeability, site constraints and effluent disposal options and prepare the full report your council needs.
-
Residential and rural subdivision requires a coordinated package of geotechnical reporting to satisfy council conditions — soil classification, land capability, slope assessment, acid sulfate soils and construction suitability. We deliver everything your DA package needs.
-
Steep or irregular sites require careful geotechnical assessment before you can design. We assess slope stability, identify landslide and geohazard risks, and provide retaining wall recommendations — turning challenging sites into approvable, buildable assets.
-
If your development site has a history of industrial, agricultural or potentially contaminating land use, councils and certifiers may require a Preliminary Site Contamination Assessment (Phase 1 ESA) before approving your DA. We prepare desktop-based Phase 1 assessments identifying potential contamination risks and recommending next steps. Where intrusive investigation is required, we also deliver Phase 2 Detailed Site Investigations (DSI) — so you can progress your approvals with confidence.
-
We provide geotechnical investigation and design services for commercial, industrial and large-scale residential development — including foundation design, earthworks assessment, pavement design, and construction phase support from the same team that investigated the site.
