Mixed reality
Seeing the design
in its place,
before freezing it
The model overlaid on the real installation, on site, in front of the people who will operate it.
What the review produces
A mixed-reality review is not a demonstration. It is prepared, it is held on a date, and it leaves a written trace.
The register of observations
Every point raised during the review, with who raised it, the area concerned and what is being asked.
The annotated views
Captures of the overlay wherever it shows something: a clash, an insufficient access, a questionable connection.
The action list
What goes back into the design, with an owner and a deadline. Without that, a review produces opinions, not decisions.
The scope and the version
The area covered, the revision of the model used and the overlay conditions are fixed before the visit, and restated in the report.
A model seen on a screen is judged by people who can read a model. The same model seen in its place, on the shop floor, is judged by operations and maintenance — who see at once that a valve will be out of reach or that a passage disappears.
That is where the review earns its time: it brings up, before the design is frozen, constraints that appear on no drawing and that nobody would have put into words in a meeting.
Two moments when it is useful
The overlay does not serve the same purpose at every stage of a project.
Before the design is frozen
The planned modification is seen in its real location. Accesses, removal volumes and routes are arbitrated with the people who will live with them.
During the works
What has been built is compared with the design, area by area, and the discrepancies found are recorded like any others.
What stays in the engineering tools
Clash detection is carried out in AutoCAD Plant 3D and Navisworks, against the surveyed existing plant. Mixed reality gives something to see and discuss; it does not replace a geometric check.
The hardware
The headset is only a means. We do not build a service around a product whose life cycle is not ours to control.
We do not claim to measure by overlay. The accuracy of an on-site registration depends on the area, on the references available and on the conditions of the day; it does not match that of a survey.
A mixed-reality review is therefore judged on the decisions it brings forward, not on a stated tolerance.
Tell us which area is at stake, who needs to be around the table and by when the design has to be frozen. We will tell you what an on-site review can bring, and what it will not.
