Construction Cost Estimator

Estimate the total construction cost of a building by combining floor area, building type rate, location, and design complexity. Useful for early-stage project budgeting before detailed drawings are available.

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.
