Методология

Как рассчитываются сметы

Каждая смета строится на основе размеров комнат, состояния поверхностей, выбора материалов и региональных ставок работ.

The estimation formula

Room total = (
Materials
+ Labor
+ Surface preparation
+ Supporting materials
) × Regional multiplier
Each component is calculated as a range (min–max), so the final estimate is also a range. This reflects real-world variability in contractor pricing and material availability.

Area calculations

Floor areawidth × length
Ceiling areawidth × length
Wall area2 × (width + length) × height − windows − doors
Window deduction1.5 m² per window
Door deduction2.0 m² per door
