Geotechnical Investigation

Geotechnical Investigation

A Geotechnical Site Investigation is a critical step in the planning and development of any commercial construction project.

For commercial and non-residential projects, which typically involve larger structures, heavier loads, and more complex engineering demands, a more extensive and a broader range of analyses are required to ensure compliance with appropriate standards and safety requirements.

Equipped with a wide array of drilling and testing equipment, we provide comprehensive geotechnical investigations for a variety of projects, including commercial, industrial, institutional, and educational developments.

We also specialise in soil testing for schools, commercial properties, and government projects, ensuring they meet all applicable standards and regulations. Whether it’s a sport and field installation, pavilion, accessibility upgrade, new building, classroom, office space, or factory, our team has the expertise and experience to ensure the job is done right the first time.

With thousands of sites investigated, we bring a wealth of knowledge and experience to the table. Our commitment to accuracy and attention to detail helps our clients avoid costly mistakes often made by inexperienced or unqualified consultants, making us a trusted partner for projects of any scale or complexity.

Geotechnical Site Investigations Frequently Asked Questions

What is a geotechnical investigation?

A geotechnical investigation is usually needed for commercial, non-residential, or more complex builds. The goal is to understand the ground conditions of your site. This includes looking at soil types, rock layers, groundwater, and any potential risks, so we can give clear recommendations for foundation design and construction methods.

How is a geotechnical investigation performed?

Just like a standard site classification, the work can be done by hand or with machinery depending on what the project needs. For most geotechnical investigations, we use our specialised tight-access tracked rigs, multiple 4×4 drill rigs, and larger truck-mounted rigs.

What is the purpose of a geotechnical investigation?

A geotechnical report gives you a detailed picture of what’s happening below the surface. It usually includes:

  • Soil Classification: A breakdown of the soil and rock types on site, including strength, density, and other key properties.
  • Groundwater Information: Details about groundwater depth, seasonal changes, and how it might impact construction.
  • Geotechnical Recommendations: Guidance on foundation design, excavation, earthworks, and how to manage any identified risks.

How detailed is the final report?

Geotechnical Investigation reports are highly detailed and play a huge role in designing foundations. They help determine the right foundation type, depth, and load-bearing capacity. A thorough report helps avoid unexpected surprises during construction, improves cost planning, and reduces the chances of costly design changes later on.

What types of developments require geotechnical investigation?

These investigations are required for most commercial or complex builds, including (but not limited to):

  • Factories and warehouses
  • Commercial buildings and shopfronts
  • Retaining walls
  • Sports field infrastructure (netting, scoreboards, etc.)
  • Sporting pavilions
  • Lighting, telecom, and meteorological towers
  • Pavement/DCP-CBR investigations
  • Playgrounds, boardwalks, and shelters
  • Schools, kindergartens, and childcare centres
