The BC One Call gap in Port Coquitlam
BC 1 Call marks public utilities to your property line — always request it, it's free. But every service inside the line is private and stays unmarked. That gap is where most utility strikes happen, and liability lands on whoever dug. This service closes the gap.
Locating conditions in Port Coquitlam
Ground: Port Coquitlam sits on Pitt River floodplain silts with till toward the north side. Floodplain silts limit deep imaging south of the rail corridor; northern till scans conventionally. Shallow residential services image well throughout.
What's buried here: Postwar bungalows mid-renewal, distribution warehouses on the floodplain, and a compact older downtown with mixed-age services.

How the Port Coquitlam locate works
- 1
Capture open trenches
The cheapest as-built is the one recorded before backfill — we survey installed services in the open trench when scheduling allows.
- 2
Verify after cover
Where backfill beat us to it, GPR + EM verify the installed routes against the design drawings.
- 3
Flag the deviations
Every divergence between design and installation is documented — the differences are precisely what future crews need to know.
- 4
Issue the record
Layered CAD as-built plus PDF atlas; the property's permanent subsurface memory.
How to read the marks we leave
CSA/APWA uniform colour code. Standard practice: mechanical digging stays 60 cm clear of any mark; the last hand-width is exposed by hand or hydrovac.
Port Coquitlam questions, answered
The contractor gave us as-builts. Why verify?
Construction as-builts are routinely red-lined design drawings, not measurements — field changes, unmarked reroutes, and 'close enough' drafting accumulate. Independent verification catches the deviations before they become the next decade's mystery strikes. We find meaningful divergence on the majority of sites we check.
When is the best time to capture as-builts?
Open-trench, before backfill — survey-grade positions at minimal cost. Second best is immediately post-construction while installers remember the routes. The most expensive time is fifteen years later, which is when most owners call.
What goes into the final record?
Routes, depths, materials, junctions, valves, and access points — layered by utility in CAD, attributed with capture method and confidence, plus a readable PDF atlas. Facility managers use the atlas; engineers use the CAD.
Can you build as-builts for an old building with nothing on file?
Yes — that's reconstructive mapping: GPR + EM + sonde tracing assemble the record from the ground itself. It's the same service as utility mapping, deliberately formatted as the as-built the building never had.
Does BC One Call cover my Port Coquitlam property?
Only partially. BC 1 Call marks registered public utilities up to your property line — free, and you should always use it. Everything inside the line is private and unmarked: irrigation, gas runs to outbuildings, landscape lighting, old septic, abandoned services. Port Coquitlam's stock — postwar bungalows mid-renewal, distribution warehouses on the floodplain, and a compact older downtown with mixed-age services. — is exactly where those private surprises accumulate. Private locating closes that gap before you dig.
How do Port Coquitlam ground conditions affect the locate?
Port Coquitlam sits on Pitt River floodplain silts with till toward the north side. Floodplain silts limit deep imaging south of the rail corridor; northern till scans conventionally. Shallow residential services image well throughout. Where local conditions limit one technology, the survey leans on the others — EM tracing, sonde work, and acoustic methods — so the locate objective is met regardless of soil.
How quickly can you do a locate in Port Coquitlam?
Port Coquitlam is inside our standing Metro Vancouver coverage — typical scheduling is 24–72 hours, with same-day service often possible during business hours (Mon–Sat, 8am–6pm Pacific).
