Steel is usually the single largest material cost on an RCC project. This reconciles your actual stock movement against the Bar Bending Schedule to compute wastage directly.
Steel consumption overrun is the gap between the reinforcement your BBS/BOQ accounts for and the steel actually consumed on site. The main sources are cutting-length rounding (bar-benders round up to the nearest convenient length), excess lap lengths beyond IS 456 requirements, offcuts too short to reuse getting scrapped, and reinforcement drawings being revised without the site BBS being updated to match. Steel is typically procured in bulk against a rough tonnage estimate and consumed against a running total, not reconciled bar-mark by bar-mark — the overrun only surfaces when the final steel bill comes in higher than the BOQ provision, long after the wastage occurred.
A residential project with a BBS-planned requirement of 62,400 kg that actually consumes several thousand kg more runs a measurable wastage percentage — at ₹62/kg, even a modest gap is a meaningful five-figure cost, and because steel is typically 15-20% of total project cost, this compounds quickly across a full project.
Disciplined sites issue steel against an approved Bar Bending Schedule, track offcut reuse explicitly, and reconcile actual consumption against BBS-theoretical consumption at every floor slab, not just at project close.

Rebota's BOQ and Material Reconciliation modules track steel issued against BBS-linked BOQ quantities floor by floor, flagging any structure element where consumption crosses your defined tolerance before it compounds across the whole project.
