Cost & Quantity Estimation Tools

Standardized tools for material unit rates, quantity takeoff summaries, contingency allowances, and preliminary project budgets.

Civil & Structural 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 & QS 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 & QS 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
