Clear evidence supporting accountable project decisions

Public projects require technical evidence that is clear, traceable and verifiable. Government agencies and councils engage Geotesta to provide investigations, environmental assessments, laboratory testing, inspections and monitoring for roads, buildings, parks and other community infrastructure.

Avoid uncertainty before contract award

Inadequate site information can increase project scope, costs, approval requirements and uncertainty during tendering. Once contracts are awarded, unexpected ground conditions may lead to contract variations, construction difficulties and more complex governance decisions.

Geotesta assists clients in determining the appropriate investigation scope based upon client needs. The results are reported in such a way as to be understandable to both technical and non-technical audiences. As an approved supplier with NATA accredited laboratories and extensive field capabilities, Geotesta has supported its clients from preliminary planning through to construction assurance.

Discuss the Risk

One partner for all your ground needs

Planning and Due Diligence

Desktop review, site inspection and environmental assessment help define project risks, budgets and approval requirements.

Design and Procurement

Accurate site information supports reliable tender documentation and helps contractors understand the conditions and work involved.

Delivery Assurance

Inspection, testing, pile assessment and monitoring provide evidence of compliance and support contractual hold-point decisions.

Transparent public project delivery solutions

Geotechnical Investigation

Investigation of soil, rock, fill and groundwater to define the ground conditions your design, budget and program depend on.

Geotechnical Site Investigations

Phased site investigation that replaces guesswork with validated ground data, giving your project team recommendations they can design and build on.

Detailed Site Investigation (DSI)

Sampling and analysis that define what contaminants are present, where they sit and how far they extend.

Preliminary Site Investigation (PSI)

A desktop and site review that identifies whether contamination may be present and whether further assessment is needed.

Drilling and Rock Coring

Borehole drilling and rock coring that recover soil and rock samples from depth for engineering logging and testing.

Soil & Rock Testing

Laboratory testing that turns recovered soil and rock samples into reliable strength, movement, permeability and compaction parameters.

Hydrogeological Assessments

Assessment of how groundwater occurs and moves beneath your site, and what that means for development, excavation and dewatering.
In-situ Testing (Pressuremeter and specialty testing)

In-situ Testing (Pressuremeter and specialty testing)

Pressuremeter and other specialised in-situ tests that measure how soil and rock behave in place.

Site Classification (Residential, Commercial & Industrial)

Assessment of geology, soil behaviour and site characteristics to produce a clear classification and practical advice on next steps.

Pile Testing and Piling Supervision

Supervision during pile installation and integrity testing afterwards, giving deep foundation works verified oversight from start to finish.

Compaction Control & Ground Preparation Supervision

On-site supervision and density testing of earthworks, confirming fill and subgrade are compacted to specification before construction continues.
Road Pavement Investigations

Road Pavement Investigations

Layer-by-layer assessment of pavement and subgrade condition, so maintenance, rehabilitation or reconstruction targets the real problem.
Earth Retention & Soil Stability Solutions

Earth Retention & Soil Stability Solutions

Investigation of ground conditions and slope geometry to flag instability early and recommend practical retention or stabilisation.
Numerical Analysis

Numerical Analysis

Geotechnical modelling that tests how your design responds to load, excavation and groundwater before construction begins.

Geotechnical Inspection and Supervision

On-site inspection and supervision that verifies ground conditions, earthworks and foundations meet design and specification during construction.

Soil Index Properties Testing

NATA-accredited index testing that measures particle size, plasticity, moisture, pH and density to show how soils will behave on site.

Aggregate Testing

NATA-accredited laboratory testing of aggregates, crushed rock and source rock to confirm particle size, material characteristics and specification compliance.

Environmental Due Diligence

A review of site history and available evidence so you understand contamination risk before committing to a purchase.
Waste Classification

Waste Classification

Sampling and laboratory analysis that determine how excavated material must be managed, reused or disposed of.
Sodic Soil Assessments and Management Plans

Sodic Soil Assessments and Management Plans

Testing that identifies dispersive soils and sets out how to manage erosion, runoff and downstream impacts during development.
Underground Petroleum Storage System (UPSS) and Underground Storage Tank (UST) Assessments

Underground Petroleum Storage System (UPSS) and Underground Storage Tank (UST) Assessments

Investigation of suspected or known petroleum impacts from buried fuel tanks, defining the extent and the action required.

Groundwater Well Installation and Monitoring

Installation and monitoring of groundwater wells that define water levels, quality and movement beneath your site.
Tunnel Instrumentation and Monitoring

Tunnel Instrumentation and Monitoring

Instrumentation and monitoring for tunnelling that tracks ground movement and structural response as works progress underground.
Geotechnical Instrumentation

Geotechnical Instrumentation

Installation and monitoring of geotechnical instrumentation that measures ground movement, load and groundwater so changes are detected early.
Environmental Instrumentation

Environmental Instrumentation

Installation and monitoring of environmental instrumentation that tracks groundwater, ground gas and site conditions across the life of your project.

Mining Instrumentation

Instrumentation for mine sites that measures ground behaviour as excavation advances, comparing actual conditions against predictions to flag emerging trends.

Cloud-Based Real-Time Data Collection

Automated, cloud-based monitoring that captures more frequent readings than manual checks and makes site data available for offsite review between visits.

Examples of public assets we can support include roads, rail, bridges, culverts, buildings, parks, schools, playgrounds, sporting facilities, water supply systems and other local, state or federal infrastructure.

Geotesta has its own NATA accredited laboratory. We also have supplier prequalification status and memberships to various industry associations which are related to public sector and infrastructure works. Specific requirements will vary depending upon each individual procurement process.

Yes. Data obtained through Geotesta’s investigations and testing, supported by analysis and interpretation, can help define ground conditions and associated risks. This information may also assist in identifying provisional items and clarifying technical requirements within tender documentation before release.

Yes. The staff at Geotesta regularly coordinate with representatives of agencies, councils, project managers, designers, contractors and independent reviewers of projects.

Yes. Reports prepared by Geotesta may contain the necessary technical detail, yet clearly outline key risks, implications, limitations and recommended courses of action for decision makers who do not necessarily understand technical terminology.

Yes. Services provided by Geotesta include inspection, compaction testing, earthwork supervision, pile testing and instrumentation (as applicable) to verify performance during the course of construction.
