Unknown utilities on site
Unknown utility risk is one of the fastest ways to stall excavation and increase project exposure. A utility survey gives teams in your area a safer dig strategy before construction activity escalates.
Unknown utilities on site is typically addressed when teams need to move from symptoms to a scoped, commercially realistic plan before site works commit. When you are ready to discuss delivery, start with the Utility Survey service overview.

What causes this site issue
Utility uncertainty happens when records are incomplete, legacy services were never updated, or prior alterations were undocumented. On older or redeveloped land, unknown cables and pipes are common.
Situations where this applies
This is typically needed when recurring symptoms, project risk, or compliance concerns mean a patch repair is no longer a reliable option.
Quick checks you can try
Collect utility records, previous as-built plans, and known service entry points. Identify high-risk work zones where live services could intersect planned excavation.
Signs this issue is becoming serious
Escalate urgently when project teams are ready to excavate without verified service mapping, or when record packs conflict with what is visible on site.
How this gets resolved
We run utility detection and mapping using EML and GPR, correlate findings with records, and issue coordinated drawings so engineers and contractors can plan around real constraints.
What affects cost and complexity
Cost and complexity usually depend on access, scale of remedial work, existing condition, and whether supporting works are needed to complete the fix safely.
When to call a survey specialist
Call before excavation, drainage installation, piling, or service diversions. It is typically required when programme risk and safety obligations need to be reduced before ground is broken.
