Ground Investigation Before You Build
A ground investigation identifies the strata, water table and contamination risk so the structural engineer can design the foundations. Trial pits and boreholes are common. This guide explains why it is done and what to expect. We use the report to deliver foundations; we do not carry out the investigation.
Ground Investigation Before You Build usually becomes urgent when recurring symptoms begin affecting programme confidence, compliance, or delivery reliability.

Situations where this applies
Teams usually investigate ground investigation before you build when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.
What often triggers action
The symptoms below are the most common triggers we see before diagnosis and repair planning.
- Trial pits or boreholes
- Lab testing and report
- Recommendation for foundation type
