Catch code violations before plan check
Helonic is an AI construction drawing analysis platform for preconstruction teams using Helonic for code compliance.
Check construction drawings against IBC, ADA, fire codes, and egress requirements automatically.
Why does code compliance matter on the drawings?
A code miss caught at plan check delays the permit; the same miss caught in the field or after occupancy becomes a redesign or a lawsuit.
| Figure | What it measures |
|---|---|
| 15-20% | Reviews that are code corrections (ICC) |
| $75K | Average ADA settlement per lawsuit (DOJ) |
| 3-6 mo | Permit delay from code issues |
| 30% | RFIs that are code clarifications (Navigant) |
How does Helonic go from PDF upload to code findings?
Helonic reads every relevant sheet and surfaces violations with the exact code section so the designer can fix the citation, not guess.
- Upload your drawings. Drop your PDF drawing set into Helonic. We process architectural, life-safety, and code sheets at any size.
- AI extracts code-relevant data. Our model reads room names, occupancy types, door schedules, wall ratings, dimensions, and fixture counts.
- Cross-check against codes. Helonic compares your extracted data against IBC, ADA, fire, and egress requirements section by section.
- Code findings report. Receive specific findings with the code reference, the sheet where the issue appears, and a suggested fix.
Which building codes does Helonic check?
Helonic checks the code categories commercial projects cite most often, including IBC egress and occupancy, ADA, NEC, and NFPA fire protection.
ADA Accessibility
- Door clearances and maneuvering space
- Ramp slopes and handrail requirements
- Restroom fixture clearances
- Accessible route continuity
- Signage and wayfinding
Fire & Life Safety
- Fire-rated wall and door requirements
- Fire barrier continuity
- Smoke barrier requirements
- Fire sprinkler coverage
- Fire alarm device placement
Egress
- Occupant load calculations
- Exit width requirements
- Travel distance limits
- Common path of egress travel
- Exit sign and lighting placement
IBC General
- Occupancy classification consistency
- Construction type requirements
- Height and area limitations
- Plumbing fixture counts
- Ventilation requirements
Why does automated code review matter?
Manual code cross-referencing is slow and error-prone. Every miss turns into a plan check comment, a permit delay, or an accessibility lawsuit after occupancy.
Helonic does the cross-referencing automatically. Door clearances, exit widths, occupant loads, and fire ratings are checked against the relevant code section, with the sheet location attached to every finding.
Catch violations before plan check submission and document that code compliance was verified during design.

He works directly with structural, MEP, civil, and fire protection engineers to translate the way they review drawings into AI systems that flag the issues that actually matter in the field. Before Helonic, he built machine learning pipelines for technical document understanding and has spent the last several years interviewing licensed design engineers and discipline leads to ground product decisions in real practice rather than industry assumptions.
