The problem

The drawings are from 1998 and three retrofits ago. The new skid arrives, and the pipe run it was designed around moved 400 mm in 2011. The shutdown extends by four days and everyone blames the drawings.

What we do about it

Scan first. A registered point cloud of the actual plant, classified and published as a streamable model, lets the new design be checked against reality before fabrication starts. Clash detection against a cloud is not glamorous and it is the cheapest four days you will ever buy.

How the work runs

  1. 1

    Plan to accuracy

    Control network first, then terrestrial scans at the required density, drone for anything above roof level or inside a live area.

  2. 2

    Register and clean

    Bundle adjustment against control, removal of people, vehicles and rain, then classification into ground, structure, equipment and pipework.

  3. 3

    Publish and clash

    Octree publication for the browser, meshed derivatives for the CAD seats, and clash runs against the new design.

  4. 4

    Hand over the record

    The cloud becomes the facility record — the next retrofit starts from reality instead of from 1998.

The objection we hear most

“Scanning a whole plant sounds expensive.”

It costs less than one unplanned shutdown day at most plants. We will tell you what your day rate is before you commit — if the arithmetic does not work, we say so.

Where we have done this

Bring us the product you were told could not be configured.

Tell us the option count, the CAD you already have and the frame budget you need to hit. An engineer reads it and replies with a straight answer — including when the answer is that good photography would serve you better.

We reply to every enquiry within one business day, in your timezone — with a frame budget, not a brochure.
