What drives this estimate
Engine calculated

These are the main rules that shaped the final BIM production cost.

  • R1Base modeling time — Window6.00 h+6.00 h
  • R2Geometry complexity — complex×1.8+4.80 h
  • R3MEP complexity — low×1.1+1.08 h
  • R4Variants — 3 production (of 3 theoretical)0.00 h
Variant normalization
Engine calculated

Theoretical configuration space versus production-impacting variants actually priced by the engine.

Theoretical configurations

3

Raw permutation count (e.g. widths × heights × materials).

Production variants

3

What the engine actually priced as BIM modeling work.

Engine summary

3 theoretical configurations normalized to 3 production variants. Variant labor: 0.00 h.
