Structural Element Calculator
Enter dimensions and get concrete volume in m³. Pick the unit (mm / inches / feet / meters) for each dimension individually.
Slab
Flat slab — floor / roof / lintel
Column
Rectangular / square column
Footing
Isolated / spread footing
Circular / Cylindrical
OHT slab · circular column · water tank wall
Trapezoidal Wall
Retaining wall / battered wall — tapered cross-section
Project-Level Estimator
Enter built-up area per floor and number of floors. Consumption factors are calibrated from real RDC project data.

📐 Indicative Structural Design
The estimate is derived from a typical column-grid framed RCC structure with the indicative dimensions below. Actual sizes will be finalised by your Structural Engineer based on detailed analysis, loading, soil and seismic conditions.

🎯 Grade-wise Concrete Distribution
Per IS 456:2000 Cl.6.1 & IS 13920 (ductile detailing), compression members (footings, columns) use a higher grade than flexural members (beams, slabs). Higher grade provides greater compressive strength where axial loads are dominant, while a leaner grade is structurally adequate for bending members.
