Engineering Heuristics Note:

This calculator provides preliminary planning heuristics derived from Indian Standard IS 456:2000, IS 1893:2016, and historical benchmarks from Mansard's 150+ executed projects. Concrete volume typically ranges between 0.038 to 0.055 m³ per sq.ft depending on span dimensions, slab system (flat slab vs beam-slab), and basement retaining heights. Steel consumption ranges between 3.5 to 5.5 kg/sq.ft for residential and 5.0 to 6.5 kg/sq.ft for industrial/commercial complexes.

Final structural member schedules and exact quantities will be finalized through comprehensive ETABS/STAAD 3D modeling and soil geotechnical investigation report data.
