Engineers & Design Consultants
Provide evidence-based data to support all of your design assumptions
Use project data, not broad assumptions
Designers may rely on limited investigation, narrow testing parameters or unclear reporting to justify conservative assumptions. These gaps are often found only after review, tender or construction has begun, when design changes become far harder to make.
Geotesta helps the design team define the engineering question, then selects field and lab techniques that yield usable parameters. Findings can support foundations, retaining structures, pavements, earthworks, tunnelling, slope stability or buried utilities.
One partner across all of your project work
Scoping and Investigation
Develop a collaborative scoping document with the design team. Complete desktop studies. Conduct targeted field activities and direct the efforts towards those parameters and risks that impact the design.
Testing and Analysis
Use in-place methods such as laboratory testing methods to collect measurable data related to strength, stiffness, deformation, permeability and behaviour of various soils and rock materials.
Verification and Monitoring
Perform construction supervision services. Test piles. Install instrumentation. Compare actual performance with assumed behaviours as defined in the design documents and agreed-upon criteria.
Data for the design question
20+ years. 15,000+ projects. One connected team
Reduce Project Risk
Identify potential ground issues early to minimise costly surprises, delays and design changes.
Keep Projects Moving
Fast investigations, responsive site attendance and timely reporting help maintain project timelines.
Build with Confidence
Accurate practical engineering advice support informed decisions from planning through construction.
Trusted Technical Expertise
Benefit from NATA-accredited laboratory testing, experienced engineers and reliable Australia-wide support.
Accreditations
Trusted. Certified. Backed by Industry Leaders.
Fast report turnaround sets Geotesta apart, giving your team the evidence needed to keep decisions and projects moving. You will receive an obligation-free, transparent quote with the scope, costs and expected delivery timeframe clearly defined. NATA-accredited laboratory testing, ISO 9001 and ISO 45001 certification, transport authority prequalification, supplier panel approval and relevant professional affiliations provide further confidence through procurement, technical review and regulatory scrutiny.
Frequently Asked Questions
Yes. The geotechnical investigation team at Geotesta will review all relevant project information including drawings, loadings, geometry, available information and your design questions prior to recommending field investigation locations, investigation depths, field testing methods and required laboratory testing.
Yes. Geotesta can conduct a range of specialised field investigations, including pressuremeter testing, thermal and electrical resistivity testing, dynamic cone penetration, lightweight drilling and wash boring, and falling weight deflectometer testing. Other targeted investigation methods can also be arranged where appropriate to the project.
Yes. Geotesta operates a NATA accredited laboratory for testing soil, rock, and construction materials. This means we are able to reduce handovers to third parties and improve communication and coordination between our field teams and laboratory staff.
Yes. We will review the existing information and identify if it can be appropriately used to address your design questions. Where the existing information cannot adequately answer your design questions, we will recommend targeted additional investigations.
Yes. Monitoring instrumentation can be used to compare measured ground movements, settlements, deformations, groundwater or vibrations to predicted behaviour and agreed-upon thresholds.
Yes. Geotesta can inspect exposed conditions, complete targeted testing and provide updated interpretation when construction reveals conditions that differ from the original model.
