Vacuum Excavation for Construction & Development
Pre-construction service verification and enabling works that manage CDM risk before groundworks begin.
For developers and main contractors, the groundworks phase is where hidden risk turns into real cost. A live service no one expected, a redundant main in the wrong place, an obstruction that stops a foundation - each one can halt the programme, trigger a safety investigation and eat into margin before the build is even out of the ground. Vacuum excavation is how experienced principal contractors take that risk off the table early.
Used before groundworks begin, non-destructive digging proves what's underground so the site can be de-risked and the programme protected. It comes into its own on brownfield and redevelopment sites, where unrecorded and live services are the norm rather than the exception, and where putting mechanical plant into unknown ground is a gamble no one should take. Pre-construction service verification, enabling works, trial holes for foundation and drainage design, and service diversions to unblock plots - all delivered safely and precisely.
How we support build programmes
Pre-construction verification
Proving buried services before groundworks so the build starts on solid, evidence-led ground.
Enabling works
Safe excavation and service clearance to prepare a site before the main groundworks package begins.
Trial holes for design
Foundation and drainage trial holes that confirm depths and positions for the design team.
Service diversions
Diverting existing utilities to unblock plots and enable new build layouts.
What it delivers
- CDM risk managed
- Brownfield ready
- Fewer surprises
- Protected build programme
- Safer groundworks
Manage CDM risk with evidence
Buried services are a recognised hazard under CDM, and the safest place to manage them is at the planning stage - with confirmed data, not assumptions. Combining utility verification and trial holes and potholing before the groundworks start gives your team the evidence to design out risk and keep the build moving.

Frequently asked questions
- Why do developers and main contractors use vacuum excavation?
- Because it takes buried-service risk out of the groundworks phase. Proving and exposing services before excavators arrive means fewer strikes, fewer stoppages and a build programme that isn't derailed by something no one knew was there - all of which supports the principal contractor's CDM duties.
- Can you work on brownfield sites with unknown services?
- Yes - that's one of the strongest cases for it. Brownfield and redevelopment sites are notorious for redundant, unrecorded and live services. Non-destructive digging lets us investigate and expose them safely without the risk that comes from putting mechanical plant into unknown ground.
- Do you dig trial holes for foundation design?
- Regularly. We provide trial holes and inspection pits that confirm the position and depth of services and obstructions for foundation and drainage design, so the design team is working from confirmed data rather than assumptions.
- How does this help with CDM risk?
- Buried services are a recognised hazard under CDM. Verifying and exposing them non-destructively before groundworks lets the principal contractor design out the risk at the planning stage - with evidence - instead of discovering it with a bucket.
