EVAVO R&D · interactive workflow demonstration
Evidence-controlled takeoff
A public-safe construction measurement workflow that keeps quantities connected to source, scale, method and review state.
Problem
Drawing sets, revisions and commercial quantities are easy to separate from the evidence that makes them trustworthy.
Constraint
The demonstration must not imply professional sign-off, production readiness or certainty that the evidence has not earned.
Thinking and craft
Make provenance and uncertainty part of the working experience, not an appendix added after the number has already travelled.
A restrained takeoff review surface uses synthetic sheets and quantities so the control model is visible without exposing project documents.
What you can explore
- 01Choose a synthetic drawing area
- 02Inspect its measurement basis
- 03Compare the check method
- 04See why export remains blocked or becomes reviewable
Result
A package-ready interactive explainer for evidence-led quantity workflows, grounded in implemented AIQS contracts rather than a fictional client story.
The most valuable behaviour is refusal: the system preserves missing evidence and disagreement instead of smoothing them into a confident answer.
