Civil Engineering Automation:
Drawings to BOQ, BBS & Plan in Minutes

Infrava reads uploaded structural drawings (PDF, DWG, DXF), parses vector geometry, and generates pure deterministic Bill of Quantities (BOQ), Bar Bending Schedules (BBS per IS 2502), and quantity take-offs with multi-tier Maker-Checker verification.

Direct Vector Parsing

Reads true vector geometry from DXF, DWG, and vector PDFs. Extracts column schedules, beam cross-sections, and slab boundaries directly without raster blur.

Bureau of Indian Standards Code Compliance

Strict mathematical adherence to IS 2502 (rebar cutting lengths & hooks), IS 1786 (steel nominal weights), IS 456 (concrete proportions), and IS 13920 (seismic detailing).

Audit-Stamped Excel Delivery

Generates audit-ready Excel workbooks containing live formulas, clause references, element tags, and verification hashes for contractor billing reconciliation.

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.
