How the formula works
Base Cost = Area × Cost/SqFt × Location Factor × Quality Factor | Total Cost = Base Cost + Professional Fees + Land Cost + (Base Cost × Contingency / 100)
- Base Construction Cost = Floor Area × Cost per Sq Ft × Location Factor × Quality Factor
- Quality Factors = Standard (1.0), Premium (1.4), Luxury (2.0)
- Building Type Factors = Residential (1.0), Commercial (1.2), Industrial (0.9)
- Contingency = Percentage added to base cost for unexpected expenses
- Total Cost = Base Cost + Professional Fees + Land Cost + Contingency Amount
- Final Cost per Sq Ft = Total Cost ÷ Total Floor Area
- Total Floor Area includes all floors (Area × Number of Floors)
