3D laser scanning for industrial plants: as-built, revamps and BIM

What is industrial plant laser scanning?

Industrial plant scanning captures process areas, piping, equipment and steel structures exactly as built. Terrestrial, mobile (SLAM) or drone scanners record millions of measured points across the facility. Those points are registered and quality-checked into one coordinate system, producing an objective spatial record of the plant as it stands today — indoor and outdoor, at height and at congested ground level.

Unlike a drawing, a point cloud isn't an interpretation of the plant — it's a direct measurement of it. That distinction matters once a facility has been modified a dozen times since it was built.

Why plants need an accurate as-built record

Industrial and power facilities change constantly: new tie-ins, replaced equipment, revamps, expansions. Original drawings fall out of date within a few years of commissioning, and planning new work against the wrong geometry causes clashes, rework and lost time on a live site. An accurate as-built record removes that risk — and it's the foundation for scan-to-BIM and a digital twin.

What you get: from point cloud to as-built BIM

Typical deliverables, at the level of detail your workflow needs:

• A registered, QA'd point cloud of the plant
• As-built 2D drawings — plans, sections, P&ID-supporting layouts
• As-built 3D / CAD of piping, equipment and structures
• As-built BIM — intelligent, object-based models (scan-to-BIM)
• A digital twin data foundation, handover-ready for your platform

We deliver the accurate as-built record; process and design decisions stay with your engineers.

Where it's used

• Brownfield revamps & modifications — design against the real plant, not old drawings
• Maintenance & shutdown/turnaround planning — scope and prefabricate off an accurate model
• Equipment replacement & retrofits — fit new skids, machinery and lines into existing space
• Power & energy facilities — generation, substations and energy infrastructure

See our Industrial & Power and Oil & Gas pages for sector specifics, and our note on why brownfield revamps need an accurate as-built first.

Scanning a live plant: access, safety and the right tool

Accuracy comes from matching the method to the asset. We combine terrestrial scanning for survey-grade detail, mobile/SLAM for large or complex areas on the move, and drone capture for elevated or inaccessible structures — planned around operational constraints, permits and site safety to minimise disruption. See 3D laser scanning for the full toolkit.

A foundation, not lock-in

We own the survey-grade as-built foundation — point cloud, 3D and BIM. A live digital twin, IoT or simulation runs in your platform: you keep the data and avoid vendor lock-in.
