Most HSB manufacturers rebuild the BVX file from scratch for every revision. Excel sheets, manual part numbering, hand-fixed angles. One transposition and the saw cuts wrong. For a typical project with 5–7 revisions, that's 5–7 rounds of re-entry — each one a fresh opportunity for a €80 miscut on a load-bearing stud.
A miscut on a load-bearing stud is €80 in material. Multiply by the element count, the revision count, and the projects per year — and you get a number most production managers refuse to look at. One wrong element delivered to site can halt the crane, idle the crew, and cost €2,000–€5,000 in a single afternoon.
The machines are precise. The software upstream is capable. The gap is the handoff — the spreadsheets, the copy-paste, the re-entry. Prefab manufacturers who close that gap absorb revisions cheaply instead of expensively. The ones who don't keep paying in failure costs.
A mid-sized HSB manufacturer in the Netherlands was spending 6–8 hours per project re-entering BVX data across revisions. With five active projects at any time, that's one FTE doing nothing but data re-entry. The errors they caught cost less than the ones they didn't.
