Fórmulas que Debes Saber
Crawl Space Ventilation Area
Minimum Net Vent Area (sq ft) = Crawl Space Area (sq ft) ÷ 150Excavation Volume (cubic yards)
Volume (cu yd) = [(Length + 2×Clearance) × (Width + 2×Clearance) × Depth (ft)] ÷ 27Foundation Wall Headroom (Concrete Block)
Headroom ≈ (Number of full 8-inch block courses × 8 in) + Cap block thickness (in), converted to feet and inchesElevation Difference Between Site Corners
Max Elevation Difference = Highest Corner Elevation − Lowest Corner ElevationBoard Feet of Lumber (from table factor)
Board Feet = Surface Area (sq ft) × Table Factor (bf per 100 sq ft) ÷ 100Box Header Track Length
Track Length = Header Length + 2 inches (1 inch snipped flange at each end)Rough Opening Width Allowance (Nonload-Bearing Steel Wall, Interior Door)
Rough Opening Width = Door Width + (1½ in × 2 sides) = Door Width + 3 inches
