Blog 101: "What makes a great site investigation service?"

Updated: May 21

A geotechnical site investigation is a crucial step in any construction project as it provides valuable information about the soil and rock conditions, groundwater levels, potential hazards, and the environmental impact of the site. A well designed and executed geotechnical site investigation can help to optimise the design, construction and performance of the foundations, earthworks, and structures as well as to minimise the risk of delays, cost overruns and failures.

But what makes a great geotechnical site investigation? Here are some key factors to consider:

Scope and objectives of a site investigation service

A geotechnical site investigation service should be tailored to the specific needs and

requirements of the project, taking into account the type, size and location of the proposed development, the geology and hydrogeology of the site, the expected loading and settlement conditions, the design codes and standards as well as the environmental and social aspects.

The scope and objectives of the investigation should be clearly defined and agreed upon by all the stakeholders, including the client, designers, the contractor, and the geotechnical engineers.

Methodology and techniques

A geotechnical site investigation should employ a combination of appropriate methods and techniques to collect reliable and representative data about the site.

These may include desk studies, field reconnaissance, geophysical surveys, boreholes, in situ tests, laboratory tests, monitoring and instrumentation.

The selection of methods and techniques should be based on the availability of resources, the accessibility of the site, the quality and quantity of data required, and the level of accuracy and reliability needed.

Reporting and communication

A geotechnical site investigation should result in a comprehensive and concise report that summarised the findings and conclusions of the investigation, as well as provides relevant information for design and construction. The report should also be communicated effectively to all the stakeholders, using appropriate formats and channels.


A truly great geotechnical site investigation is not only a technical exercise but also a collaborative process that involves planning, coordination, communication, and teamwork among various parties. A great geotechnical site investigation can make a significant difference in the success of any construction project.
