GLOSSARY / Construction & investigation

Borehole

A drilled opening used for a defined investigation or installation purpose. Its location, depth and drilling method are important inputs to project planning.

THE RRS GLOSSARY

Why it matters to a project

For UXO scoping, a location plan without depths and methods is incomplete. Access, ground conditions and any proposed specialist equipment also need consideration.

PROJECT EXAMPLE

A revised borehole schedule is reviewed after the design team changes the investigation depth.

A useful distinction

A general site assessment should not be treated as a task-specific method for every drilling activity.
