Engineering plan and drawing analysis
Inteloflow builds computer-vision systems that read scanned engineering plans and drawings, detect the elements you care about, and export structured data your team can work with. Production systems include legend and label OCR, thresholds that hold across scan quality, and a human-in-the-loop layer for the edge cases.
Priced by drawing complexity and target accuracy, established on your real scans during scoping. Fixed-price after a scoping call. No hourly billing.
What we build
- Element detection on scanned plans: routes, symbols, and annotations separated from noise
- Legend and label OCR that propagates types and sizes onto each detected element
- Detection that holds across scan-quality variation without per-scan tuning
- Human-in-the-loop review interfaces so engineers confirm or correct results without re-running the pipeline
- Structured exports that feed your downstream tools instead of producing another PDF
Proven in production
Pipe-route detection on scanned sanitary plans lifted from 60% to 96% accuracy, with per-plan processing time down from 8 minutes to under 1.

How much does automated plan analysis cost?
Projects start at $6,000 USD. The price is driven by drawing complexity, the number of element types to detect, and the accuracy bar. We establish feasibility on a sample of your real scans before quoting.
How accurate is automated plan detection?
Our production pipe-route system runs at 96% detection accuracy, up from the 60% the client's previous approach managed, with a human-in-the-loop layer catching the remainder. Your number depends on your drawings, which is why we test on real samples first.
What about poor-quality scans?
The pipeline is built to hold across scan-quality variation: HSV-based color separation and centralized thresholds instead of per-scan manual tuning. Genuinely unreadable scans get flagged for human review rather than guessed at.
Do our engineers still check the output?
Yes, efficiently. A correction interface lets engineers confirm, reject, or adjust detected elements without re-running the pipeline, so review takes minutes instead of redoing the work.
