Net Efficiency

85%

Transparent Formula Definition

Annual Savings = (25 drawings/mo) × (6.5 hrs/drawing) × (₹450/hr) × 12 months × 0.85 net efficiency = ₹7,45,875

*The 0.85 factor accounts for 15% engineer review & verification time. No hidden assumptions.

Detailed Assumptions Behind the Economic Model

Standard manual BBS preparation for a complex multi-span RCC beam schedule or column schedule requires approximately 6 to 8 hours for a qualified Quantity Surveyor (measuring bar cut lengths, calculating bends, applying laps, and typing into spreadsheets).

Infrava performs the vector extraction and deterministic IS 2502 cutting calculation in under 60 seconds. We apply a net efficiency factor of 85% (0.85 multiplier) to allow 15% of engineer review time under the Maker-Checker workflow.
