Site Investigation – Guide & FAQs

Phase 1 Site Investigations

Introduction

Local authorities and structural engineers often ask for a geotechnical or contaminated land investigation at the early stages of a construction project, either for planning or for design. If you have never needed a site investigation before, you will probably have a lot of questions and will be wondering why you need one. Soilutions have put together helpful Guides that explain everything you need to know about Phase 1 and Phase 2 site investigation. We’ve also answered many of the questions we get asked about contaminated soils below.

Phase 1 and Phase 2 of a site investigation are crucial for the safety of the end users of the site – they make sure the soil is not unacceptably contaminated and that the right foundations are chosen for any new buildings. Soilutions are happy to help you get the information you need to make sure your responsibilities as a developer are met.

If you have any further questions or want to discuss your project with us, please get in touch.
