When used correctly, geophysical surveys can be important and useful components of the site investigation toolbox. Geophysical surveys can provide clients with a cost-effective alternative – or, preferably, complementary service to – traditional intrusive methods of investigation. From identification of otherwise unknown targets through to confirmation and mapping of know geological horizons, there is often a positive outcome for a well-designed and well-executed survey.

However, the range of geophysical services, and their limitations, is often not fully understood by clients. Unfortunately, inappropriate techniques can be utilised, or appropriate techniques incorrectly deployed, when the communication between client and practitioner is unclear. Where, how and by whom a survey is undertaken can have a significant impact on the outcome.

In this webinar, we will seek to provide an overview of when geophysical surveys should be best scheduled within a project timeline and key factors that clients should consider when commissioning geophysical surveys. Whether the survey is for the identification of buried services, to locate potential sinkholes or to map the extent of former foundations, there are some common best practice principals that all survey proposals should follow. Clients that are able to educate themselves on some of the basic principles, or to understand where to look for additional information, are much more likely to use geophysical surveys successfully in their projects.
