Civil
Soil Bearing Capacity Calculator
Estimate the ultimate bearing capacity of soil beneath a square footing using Terzaghi's general bearing-capacity equation. Foundational geotechnical design input — used with appropriate safety factors to determine maximum allowable footing loads.

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.
