From manual drawing-based estimation, To structural estimation that automatically derives quantities and basis from BIM models。

Structural estimation at the schematic design stage relied on experts reading drawings by hand, facing challenges of time, person-dependence, and hard-to-trace basis.

• We want to drastically shorten manual drawing-based estimation

  Estimation lead time: days
• We want anyone to estimate at the same accuracy without relying on experts

  Calculation is person-dependent with varying accuracy
• We want to trace and verify the calculation basis anytime

  Reproducing and explaining the basis is laborious
• We want to use existing BIM models directly for estimation

  Can't link IFC to estimation
