Cost & Quantity Estimation Tools
Standardized tools for material unit rates, quantity takeoff summaries, contingency allowances, and preliminary project budgets.
Construction Live Tool
Steel Weight Calculator
Compute structural steel and reinforcement weight for plates, bars, pipes, and standard sections using steel density.
W = V × ρ_steel (ρ ≈ 7,850 kg/m³) Construction Live Tool
Construction Material Quantity Takeoff Calculator
Quantity takeoff for bulk construction materials with wastage: aggregate, sand, cement, and general volume-mass conversions.
Q = V × (1 + wastage/100) · m = Q × ρ Construction Live Tool
Construction Cost Escalation & Scenario Calculator
Escalate a base construction cost to a target date with a user-supplied annual rate and compare alternative escalation scenarios.
C(t) = C₀ × (1 + r/100)^n · n = days ÷ 365.25
