Pre-Excavation Scanning in Duncan, BC

One Call marks public utilities to the property line and only those registered. Private services — irrigation, gas to outbuildings, landscape lighting, old septic, abandoned lines — are invisible to it. Most strikes happen on exactly those, and liability lands on whoever dug.

Abandoned-in-place services, owner-installed plastic gas and water runs, buried oil tanks in pre-1965 neighbourhoods, and duct banks that left the drawings decades ago. Every one is a strike that didn't happen.

Standard practice: mechanical excavation to within 60 cm of a mark, hand exposure from there. Our depth flags tell the operator when targets enter the cut profile.

Yes — same-day scans within business hours are routine. Marks go down, photos are taken, the report follows by email, and the excavation proceeds the same morning where scheduling allows.

Duncan sits on Cowichan Valley alluvium — sands and silts with seasonal saturation. Summer scans reach well into the alluvium; winter saturation shortens range. Farm and First Nations lands carry generations of undocumented lines. We select antenna frequency to match — and where local ground limits radar depth, we pair GPR with electromagnetic locating, acoustic methods, or tracer gas so the survey objective is met regardless of soil conditions.

Duncan is part of our standing Vancouver Island service area — the same certified technicians and equipment that cover the rest of the region. Scheduling is typically within 24–72 hours, with same-day response often possible during business hours (Mon–Sat, 8am–6pm Pacific).
