What is a Geotechnical Site Investigation?
Understanding Ground Conditions Before Construction Begins
Environmental investigations help identify contamination, hazardous materials, environmental constraints, and compliance requirements that may affect a site's suitability for development, acquisition, or ongoing use.
At BHM Geotechnical, we provide practical environmental advice through:
These services help clients understand environmental risks before they become costly project challenges. Our services support residential, commercial, industrial, infrastructure, and land development projects across Adelaide and South Australia.
Advanced Ground Investigation Techniques: Surface Exploration & Subsurface Investigation Services
At BHM Geotechnical, we use modern field testing equipment, advanced investigation methods, and laboratory analysis to achieve a thorough understanding of site conditions.
Surface Exploration & Site Assessment
Surface exploration provides valuable information about existing site conditions before intrusive investigations commence. Methods may include:
- Site walkovers
- Geologic mapping
- Photogrammetry
- Geophysical investigations
- Surface condition assessments
- Drainage observations
These assessments help identify potential constraints and plan the scope of the field investigation.
Subsurface Investigation & Testing
Subsurface exploration involves investigating the conditions beneath the ground surface through drilling, sampling, and in-situ testing. Methods may include:
- Borehole drilling
- Test pit investigations
- Soil sampling
- Rock sampling
- Groundwater monitoring
- Piezometer testing
- In-situ field testing
Samples recovered from the site are analysed in laboratory conditions to determine engineering characteristics and design parameters required for construction and development projects.

A Structured Approach to Reliable Site Information
Desktop Study & Literature Review
We review site history, geological records, existing reports, and project requirements to identify potential constraints and determine the scope of investigation.
Site Walkover
Our engineers conduct a detailed site inspection to assess existing conditions, identify visible risks, and plan the most appropriate investigation strategy.
Field Investigation
Boreholes, test pits, soil sampling, groundwater monitoring, and in situ testing are conducted to gather accurate site-specific geotechnical data.
Laboratory Testing
Recovered samples are tested to determine soil strength, classification, permeability, and other engineering properties that influence design decisions.
Geotechnical Report
Findings are compiled into a detailed geotechnical report for construction, outlining site conditions, identified risks, foundation considerations, and engineering recommendations.
Reducing Risk Before Construction Starts
A professional geotechnical site investigation helps developers, builders, engineers, and property owners make informed decisions before construction begins.
Avoid Costly Foundation Failures
Identify problematic ground conditions before construction starts.
Confirm Soil Bearing Capacity
Determine whether the ground can safely support proposed structures.
Improve Design Accuracy
Provide reliable data for foundation, pavement, and retaining structure design.
Reduce Construction Risks
Identify groundwater, drainage, settlement, and excavation challenges early.
Support Regulatory Compliance
Meet engineering, planning, and development approval requirements.
Minimise Unexpected Costs
Reduce the likelihood of variations, delays, and construction-related issues.

Let's Clear Them Up
What are the stages of a site investigation?
A Geotechnical Site Investigation typically includes a desktop study, site walkover, field investigation, soil and rock sampling, laboratory testing, and the preparation of a geotechnical report. These stages help assess ground conditions and provide recommendations for safe design and construction.
What is the importance of a site investigation?
A site investigation identifies soil, rock, groundwater, and environmental conditions that may affect construction. The information helps reduce project risks, support foundation design, improve construction planning, and ensure compliance with engineering standards and development requirements.
When is a Geotechnical Site Investigation required?
A Geotechnical Site Investigation is typically required before residential, commercial, industrial, and infrastructure developments. It helps assess ground conditions, identify potential risks, support foundation design, and satisfy planning, engineering, and construction requirements.
What is a Phase 1 Site Investigation?
A Phase 1 Site Investigation, also known as a Preliminary Site Investigation (PSI), reviews historical site records, land use information, and environmental databases, and combines this with a site inspection to identify potential contamination risks and determine whether further investigation is required.
What is a Phase 2 Site Investigation?
A Phase 2 Site Investigation, also known as a Detailed Site Investigation (DSI), involves sampling of soil, groundwater, and environmental media to determine the nature, extent, and severity of contamination. The findings help assess risks to human health, development, and the surrounding environment.
Why do I need a Phase 2 Site Investigation?
A Phase 2 Site Investigation may be required when a Phase 1 assessment identifies potential contamination risks. It provides detailed environmental data needed to support planning approvals, development applications, remediation strategies, and compliance with environmental regulations.
