Helonic is an AI construction drawing analysis platform for teams asking how Helonic reviews construction drawings.
The customer-facing path from PDF upload to accepted RFIs
Helonic reviews construction drawings in four steps: upload a 2D PDF set (or pull it from Procore or Autodesk Construction Cloud), read every sheet, flag issues with page coordinates and severity, then let a reviewer accept findings before they become RFIs in the system of record.
Book a demo to walk this path on your own sheets
A 2D PDF drawing set is the input. That can be one bound package or a folder of discipline PDFs. Specs can ride along when you want material mismatches checked against the sheets.
Teams that already store drawings in Procore or Autodesk Construction Cloud can pull the set from there instead of downloading and re-uploading. Procore integration and Autodesk integration cover that hop.
Helonic does not ask for a BIM model, a federated NWC, or a Revit file. If you have those, keep using them for 3D clash. The PDF set is still what most trades build from, which is why AI for construction drawings starts there.
Helonic reads every sheet in the package, then compares information that lives on more than one sheet. A duct size on M-201 against a beam on S-301. A door tag on A-101 against the door schedule. A note on the structural general notes against the foundation plan.
That is the same work a coordination review is supposed to do. Manual review samples 10 to 15 percent of sheets on a large set. Helonic reads all of them, then hands a person a list. The method in how to review construction drawings still applies to what you do with those findings.
Every Helonic finding includes a category, a severity, a written description, and exact page coordinates. The reviewer opens the sheet and sees the box, not a note that only says "see structural."
Categories and examples live on what issues Helonic catches. Severity is high, medium, or low so triage can start with the findings that stop work or fail plan check.
A person on the project still owns accept and reject. Helonic does not stamp the set and does not create RFIs on its own. That is the same rule as any other markup: software can point, a reviewer decides.
Typical owners of that queue are a VDC lead, a QA/QC manager, a project engineer, or the architect of record's document checker. Rejected findings stay in the run as a record. Accepted findings can move into RFI generation.
Accepted findings become RFIs that push into native Procore and Autodesk Construction Cloud integrations. The RFI carries the description and the sheet location so the recipient is not hunting for the conflict.
Teams that are not connected yet can still export findings and write RFIs by hand. The review does not depend on the integration. The integration only removes the copy-paste step. What is Helonic covers why the product sits next to those systems instead of replacing them.
Most Helonic reviews return the same day once the PDF set is uploaded. A 200-page commercial package and a 40-page residential set both go through the same path. Page count changes runtime, not the steps.
Reviewer triage is the part that still follows your calendar. Helonic can mark the sheets in hours. Deciding which findings become RFIs is still a meeting, or a quiet hour with the list.
Practitioner insight
“The useful part is not that it finds things. Every finding has a sheet and a box, so I am not hunting through 400 pages trying to remember where the reviewer saw the conflict.”

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.
