Geotechnical

We deliver geotechnical advice across a broad range of development and infrastructure sectors, tailoring practical solutions to suit site conditions, project scale, and approval requirements.

• Residential developments including subdivisions, low-rise and high-rise projects.
• Commercial mixed-use and multi-storey developments.
• Industrial facilities, warehouses, logistics hubs, and industrial estates.
• Utilities and infrastructure projects including trenches, underbores, pumping infrastructure, and Battery Energy Storage Systems (BESS).
• Road and rail infrastructure projects.

Geotechnical investigations are undertaken to support planning approvals, civil and structural design, and construction planning. Each assessment is designed to provide clear, defensible recommendations that support practical and cost-effective project delivery.

Services include:

• Site classification in accordance with AS 2870.
• Site subsoil classification for earthquake action.
• Geotechnical parameters for civil and structural design.
• Foundation and bearing capacity assessments.
• Flexible pavement thickness design.
• Earthworks and subgrade preparation requirements.

We assess groundwater conditions and earthworks requirements to support excavation planning, site preparation, and construction methodology development. These inputs help reduce uncertainty and improve constructability outcomes.

Services include:

• Groundwater assessment and monitoring.
• Earthworks and subgrade assessment.
• Site preparation recommendations.
• Excavation condition assessments.
• Construction-related vibration assessments.
• Ground improvement considerations.

Slope stability, excavation works, and retaining structures are assessed to identify ground risks early and inform safe, practical design and construction solutions.

Services include:

• Batter slope assessments.
• Retaining wall design advice.
• Excavation stability assessments.
• AGS slope risk assessments.
• Ground movement and stability considerations.
• Temporary works considerations.

During construction, we provide ongoing geotechnical support to verify ground conditions, confirm design assumptions, and manage unforeseen site conditions as they arise.

Services include:

• Cut and fill formation inspections.
• Foundation bearing capacity verification.
• Crane pad assessments.
• Working platform assessments.
• Bored pile supervision.
• Proof roll inspections.

Understanding ground conditions early is critical to reducing project risk, managing cost, and avoiding delays. We work closely with clients and project teams to provide clear, timely advice that supports confident decision-making across all stages.

Key outcomes include:

• Clear and practical reporting.
• Responsive technical support.
• Risk-based recommendations.
• Efficient investigation and approval pathways.
• Construction-aligned solutions.
