EM + GPR Locating · For GCs & construction managers
EM + GPR utility locating for general contractors.
On your site, a struck utility is your delay, your change order, and your incident report — regardless of which sub was holding the shovel. Subsurface surprises cascade into schedule and budget, and 'we didn't know it was there' is an expensive sentence on a project with a critical path.

We're the locating partner that de-risks the ground for the whole site: dual-method EM + GPR clearance for every dig, concrete scanning before you cut or core a slab, depth mapping for coordination, and documentation that protects the project file. One subsurface partner, every trade's dig covered.
What general contractors hit
- Utility strikes that stop the job and trigger change orders
- Slab cores and saw-cuts hitting rebar, PT, or conduit
- Sub-trade digs uncoordinated against the utility picture
- Unknown site services on redevelopment and infill sites
- Project-file exposure when locates aren't documented
How we fit your workflow
- Site-wide EM + GPR clearance feeding the dig sequence
- Concrete scanning before every core, cut, or anchor
- Depth map for trade coordination and conflict analysis
- Documented locates for the project record and incident defence

ViewGeneral Contractors ask
Can one partner handle locating for all my trades?
That's exactly the model — a single subsurface partner who clears every dig on the site (EM + GPR), scans every slab before it's cut or cored, and maintains one depth map the whole project coordinates against. It beats each sub arranging their own ad-hoc locate, because the picture is consistent, the documentation is centralised, and nothing falls through the gap between trades.
How does this protect the project file?
Documented, dual-method locates with depths and dates are the evidence that diligence was done — which matters enormously when a strike or a dispute lands on your desk. 'The site was cleared by EM and GPR on this date, here's the marked map and the potholing record' is a far stronger position than reconstructing what someone thought they checked. We build the documentation into every survey for that reason.
Do you scan concrete as well as locate utilities?
Yes — concrete scanning (GPR) and utility locating (EM + GPR) are the same crew's complementary skills. Before a core, saw-cut, or anchor, we clear the slab of rebar, post-tension cables, and embedded conduit; before a dig, we clear the ground of utilities. On a construction site you need both constantly, which is why having one partner who does both keeps the schedule moving.
