The Engineering Edge

Why Obrix is Built Differently

Construction in India suffers from disconnected tools, opaque estimation, and fragmented labor. We combine civil engineering expertise with modern digital execution.

Engineer-Founded

Founded by civil engineers who understand site realities, structural drawings, IS codes, bar bending wastage, and field challenges first-hand.

Technology-First

Deterministic mathematical calculation engines instead of guessing. Exact formula breakdowns, audit trails, and digital Maker-Checker governance.

Built for Indian Sites

Designed ground-up for Indian Standards (IS 456, IS 1786, IS 2502, IRC 112) and multilingual site communication in Hindi, Marathi, and English.

Transparent & Accountable

Honest about our stage, clear about our timelines, and committed to deliver quality work on site and rigorous calculations in software.

Leadership

Built by Civil Engineers for the Real World

Obrix was established in Thane by Raghuraj Rai and Disha Patil with a unified vision: eliminate estimation errors through software automation, elevate skilled construction trades, and construct high-integrity infrastructure.

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

Infrava reads uploaded structural drawings (PDF, DWG, DXF), extracts geometries, and generates pure deterministic Bill of Quantities (BOQ), Bar Bending Schedules (BBS), and schedules with Maker-Checker multi-level approval.

System Capabilities

Engineered for Structural Rigor

1. Drawing Reading

Native parsing for DXF and DWG via vector geometry extraction, high-res PDF extraction, and vision-assisted scan OCR. All entities tagged with bounding boxes for visual verification.

2. Automated BOQ

Deterministic calculation engine with pure math functions. Every quantity references its source drawing coordinate, standard formula, and code clause. Zero AI hallucination.

3. Bar Bending Schedule (BBS)

Full rebar cut lengths, bend deductions, hook allowances, and lap lengths per IS 2502 & IS 1786. Generates diameter-wise tonnage and cutting optimization.

4. Planning & Scheduling

Automatic generation of Work Breakdown Structures (WBS) directly from element quantities. Chainage-based planning for highways and level/pour scheduling for RCC buildings.

5. Maker-Checker Workflow

Hierarchical review chain (Engineer Maker > Checker > Approver). Line-level comments, audit trails, and cryptographically verified digital approval stamps.

6. Web, Mobile & Windows

Full web dashboard for billing engineers, offline Windows workstation application for heavy CAD files, and mobile companion app for site engineers.
