How the Prince George survey runs

  1. 1

    Specification review

    The coating spec defines required DFT and measurement standard — the survey is built to verify exactly that.

  2. 2

    Aerial measurement

    Magnetic induction on ferrous, eddy current on non-ferrous substrates — the probe contacts and records automatically.

  3. 3

    Statistical coverage

    Readings across all elevations and orientations — the high, awkward areas where coating failures actually start and manual checks never reach.

  4. 4

    Compliance report

    Per-point values, statistics against specification, and GPS-tagged photos — the document the applicator, owner, and warranty all reference.

Prince George questions, answered

Why measure coating thickness at height instead of just at grade?

Because failures start where application was hardest — tops of tanks, upper stack sections, bridge members over water. Grade-level readings systematically miss the highest-risk areas. Aerial DFT samples the whole asset, which is what a credible warranty or QA file requires.

Which standards do your DFT surveys follow?

Surveys are run to the measurement practice your specification cites — SSPC-PA 2 conventions for acquisition and averaging are the common default. Instrument class covers 0–1.5 mm on ferrous and 0–0.7 mm on non-ferrous substrates.

Can this resolve a dispute with our coating contractor?

It usually settles it one way or the other: hundreds of GPS-tagged, photo-documented readings against the spec leave little to argue about. Both owners and applicators hire us for exactly that neutrality.

Do you measure DFT on bridges and infrastructure?

Yes — bridge steel, transmission structures, stacks, and tank farms are the core use cases. Anywhere the alternative is lane closures, lifts, or rope teams, the aerial economics win quickly.

Can you legally fly drones for inspection in Prince George?

Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Prince George operations run under whatever airspace authorizations the location requires. Northern capital with pulp, energy, and institutional campuses — industrial thermal work anchors the book; YXS airspace per authorization. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

How does Prince George weather affect scheduling?

Aerial inspection flies in defined weather windows — wind, precipitation, and (for thermal work) the right temperature differentials. Prince George sits in our standing Northern BC coverage, so we schedule against the local forecast and typically land the survey within days of booking rather than weeks. Mon–Sat, 8am–6pm Pacific.

What does coating thickness (dft) cost in Prince George?

Province-wide pricing — no regional premium for Prince George. Single-asset thermal surveys typically start in the high hundreds; NDT campaigns and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
