Phase 2 Site Investigation


Intrusive Ground Investigation

Good quality site investigations develop understanding of anticipated ground conditions and ensure that project constraints and costs can be identified and allowed for early on.

All work is carried out in accordance with current legislation and best practice, including BS5930, BS10175, BS1377, CLR11 and Eurocode 7.
