Civil
Concrete Volume & Mix Calculator
Calculate how many cubic yards of concrete you need for a slab, footing, or pad, including a waste allowance. Use this before ordering ready-mix concrete to avoid costly shortfalls or excess.

Civil
Excavation Volume Calculator
Calculate the volume of earth to be removed for a rectangular excavation — foundation pit, trench, or basement cut. Output is the in-situ (bank) volume in cubic metres, used for haulage planning, disposal cost estimation, and equipment sizing.
