Concrete Volume Calculator

Estimate the in-place concrete volume for slabs, footings, walls, and other rectangular structural elements using V = L × W × T. The geometric volume in cubic metres — add 5–10% waste before placing the order.

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.
