Construction Cost Estimator

Estimate total construction costs for civil engineering projects by combining project area, construction type unit costs, a regional labor multiplier, and a contingency allowance. Ideal for early-stage budget planning and bid preparation.

Beam Deflection Calculator

Compute the maximum mid-span deflection of a simply supported beam under a uniformly distributed load (UDL) using δ = 5wL⁴ / (384EI). The standard structural-design check for serviceability — verifies whether a beam stays within deflection limits like L/250 or L/360 under service loads.
