What issues does Helonic catch?

Helonic is an AI construction drawing analysis platform for teams asking what issues Helonic catches on construction drawings.

The ten categories, with examples a reviewer would recognize on a set

Helonic catches ten categories of construction drawing issues: coordination, code compliance, missing information, structural, MEP, fire safety, accessibility, constructability, dimensions, and QA/QC. Each finding includes a high, medium, or low severity rating and exact page coordinates. Reviewers accept or reject findings before any RFI is created.

What issue categories does Helonic detect?

Helonic detects ten issue categories on 2D PDF construction drawings. The list below is the published scope, not a marketing synonym soup. If a finding does not fit one of these, it does not get forced into a nearby bucket.

Category	What a finding looks like
Coordination	Duct routed through a beam, a door swing into a fixture, a riser that misses the shaft on the architectural plan.
Code compliance	Egress width that does not match occupant load, a dead-end corridor over the allowed length, a missing rated assembly at a shaft.
Missing information	A callout with no matching detail, a door tag with no schedule row, a note that says 'see structural' on a sheet that never shows the member.
Structural	A beam size that changes between the plan and the schedule, a foundation note that conflicts with the typical detail, an opening that was never framed.
MEP	A panel that lacks working clearance, a pipe slope that dies into a beam, a diffuser that lands on a light on the RCP.
Fire safety	A sprinkler omission in a rated corridor, a pull station that misses travel distance, a damper missing at a rated penetration.
Accessibility	A restroom clear-floor space that fails, a ramp slope over the allowed ratio, a door that cannot swing without blocking the accessible route.
Constructability	A sequence that cannot be built as drawn, an access panel with no path, a detail that assumes a trade is already finished.
Dimensions	A string that does not add to the overall, a grid that drifts between disciplines, a height that conflicts between section and elevation.
QA/QC	An unclouded revision, a spec section that names a different material than the finish schedule, a sheet index that omits an issued drawing.

How those findings get produced, from upload to accept/reject, is on how Helonic reviews drawings. The product definition is on what is Helonic.

How does Helonic rate severity?

Helonic rates each finding high, medium, or low. High is the pile that stops work, fails plan check, or creates a safety problem. Medium is a real conflict that can wait a day. Low is a documentation miss that still needs a decision.

Severity is a triage hint, not a stamp. A reviewer can promote or demote a finding after looking at the sheet. The coordinates stay with the finding either way, which is what makes AI for construction drawings usable in a real queue.

What does a coordination finding look like?

A coordination finding cites two (or more) sheets that disagree about the same space. The duct is on M-201. The beam is on S-301. Both are drawn as if the other trade is not there.

Helonic does that from 2D PDFs. A BIM clash test can still run in parallel if you have a model. Most field conflicts still start on sheets that never made it into that model, which is why how to find clashes in 2D drawings remains a live skill. Clash detection is the Helonic surface for this category.

What code and accessibility issues does Helonic flag?

Helonic flags code-compliance and accessibility findings when the drawing set shows a condition that conflicts with published requirements such as IBC, ADA, NEC, and NFPA. A dead-end corridor, a restroom clear-floor miss, and a panel without working clearance are typical.

Code findings still need a licensed reviewer. Editions, local amendments, and occupancy choices change the answer. AI building code review and code compliance cover that path. How to review construction drawings is still the place to put those findings in a comment log.

What does Helonic leave to the reviewer?

Helonic flags candidates. A reviewer still decides which findings become RFIs. Intent that lives only in a conversation, a verbal field decision, or a model that was never issued will not show up on the PDF pass.

False positives happen. That is why accept and reject exist. Across 1,000,000+ pages analyzed, the useful pattern is the same: coordination and missing information make up most of what teams act on, and code or accessibility flags are the ones that used to wait until plan check.

Practitioner insight

“Coordination and missing info still make up most of what we act on. The code and accessibility flags are the ones that used to wait until plan check, and those are the expensive surprises.”

What Issues Helonic Catches FAQs

What issues does Helonic catch?

Helonic detects ten issue categories on 2D construction drawings: coordination, code compliance, missing information, structural, MEP, fire safety, accessibility, constructability, dimensions, and QA/QC. Each finding includes a severity rating and the page coordinates of the cited location.

Does Helonic check building codes?

Helonic flags code-compliance findings against published requirements such as IBC, ADA, NEC, and NFPA when those rules apply to the drawing set. A licensed reviewer still confirms the cited section before the finding becomes an RFI or a comment to the designer.

Does Helonic find 2D clashes without BIM?

Helonic finds coordination conflicts across architectural, structural, and MEP sheets from 2D PDFs, without a BIM model. Duct through a beam, a door swing into a fixture, and a riser that misses the shaft are typical 2D findings.

How does Helonic mark where an issue is?

Every Helonic finding includes a severity rating and exact page coordinates so a reviewer can jump to the cited location. The mark lives on the sheet the way a pin lives on a markup, not as a note that only names the sheet number.

Should a reviewer still check Helonic findings?

Licensed reviewers still decide which Helonic findings become RFIs. The software flags candidates and does not stamp the set. False positives get rejected in triage; accepted findings can become Procore or Autodesk RFIs.

Manas is the co-founder and CTO of Helonic, where he leads engineering and AI research for construction drawing analysis. 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.
