Geotechnical ground investigations

What is a ground investigation?

A ground investigation is a process of examining the ground conditions of a site or area. It typically involves various techniques to gather information about the soil, rock, groundwater, and other geological features present in the area.

Conducting a site investigation is essential for any construction project. This data assessment is then used to inform decisions about the project's design and construction plans.

What are the stages of a ground investigation?

First, we will review existing information about the site, such as geological maps, previous investigations, and historical records. Then we will visit the project site to observe surface conditions, access points, and any visible geological features.

We then go through a process where our geotechnical engineers use a ground penetrating radar to gather subsurface information without conducting an intrusive ground investigation survey and gain insight into the physical properties of the land. We will also dig trial pits or drill boreholes to obtain soil investigations and rock samples for analysing the land.

Samples collected from the construction site are sent to a laboratory to analyse their physical and chemical properties. This analysis includes determining the soil and rock type, strength, and contamination levels.

We then work with the client to compile the findings into a comprehensive ground investigation report that summarises the ground conditions.

What are the ground investigation techniques we offer?

The ground investigation services we offer will be tailored to each site development project. The specific objectives of the site investigation will dictate the techniques we employ.

Below is just some of what we offer:

• Core sampling

• laboratory testing

• 3D ground modelling

• Cone penetration tests

• Mechanical drillings

• Hand auger drillings

• Alignment-specific deepwater, nearshore and onshore geotechnical investigations

• Onshore geophysical surveys

• Onshore paleoseismic investigations

• geologic mapping

How do I get an estimate for a ground investigation?

Get in contact with one of our experts listed below. Before we can start the proposed development, we need to review the project requirements. We also need to look at the site location plan and the existing site plan. We will then work with you to examine the proposed development plan and planning conditions to gain a comprehensive understanding of the project.
