How does Helonic review construction drawings?

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.

  1. Upload a 2D PDF set, or pull it from Procore or Autodesk.
  2. Helonic reads every sheet and flags issues with page coordinates.
  3. A reviewer accepts, rejects, or edits each finding.
  4. Accepted issues become RFIs in Procore or Autodesk Construction Cloud.

What do you upload to Helonic?

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.

How does Helonic read a multi-discipline set?

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.

1. Upload or pull the set
Drop in a 2D PDF package, or pull drawings from Procore or Autodesk Construction Cloud.
2. Read every sheet
Helonic reads architectural, structural, MEP, civil, and related sheets in the package, not a sample.
3. Flag issues with coordinates
Each finding has a category, high/medium/low severity, and the page box of the cited location.
4. Reviewer triage
A person accepts, rejects, or edits each finding. Nothing becomes an RFI until that step.
5. Push RFIs
Accepted findings become RFIs in Procore or Autodesk Construction Cloud.

What does a Helonic finding include?

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.

Who reviews Helonic findings before they become RFIs?

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.

How do Helonic findings become Procore or Autodesk RFIs?

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.

How long does a Helonic review take?

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.

Conversations with VDC leads running multi-discipline PDF reviews on commercial projects.

How Helonic Reviews Drawings FAQs

How does Helonic review construction drawings?
Helonic reads every sheet in a 2D PDF set, flags issues with page coordinates, and lets a reviewer accept findings before they become RFIs. The same path works when drawings are pulled from Procore or Autodesk Construction Cloud instead of uploaded by hand.
Do reviewers still look at Helonic findings?
Reviewers still accept, reject, or edit every Helonic finding before an RFI is created or pushed to Procore or Autodesk. Helonic marks candidates on the sheet. A person decides what leaves the review.
How long does a Helonic review take?
Most Helonic reviews return same-day once the PDF set is uploaded, including multi-discipline packages. Turnaround depends on page count and how quickly a reviewer starts triage, not on a multi-week markup cycle.
Can Helonic pull drawings from Procore?
Helonic can pull drawing sets from Procore and Autodesk Construction Cloud, then push accepted findings back as RFIs. Manual PDF upload stays available for teams that are not connected yet.
Does Helonic review specifications as well as drawings?
Helonic cross-references drawings against specifications for material mismatches when specs are included with the set. Spec review is part of the same pass as sheet review, not a separate product.

Co-founder & CTO, Helonic

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.

Areas of focus
  • AI for technical document understanding
  • Cross-discipline coordination workflows
  • Code compliance automation (IBC, NEC, NFPA, IPC, IMC, ASCE)
  • Structural and MEP drawing review systems

How this page was researched: Workflow described from the customer-facing Helonic review path: PDF upload or PMS pull, full-set analysis, sheet-coordinate findings, human accept/reject, and RFI push. Turnaround reflects same-day delivery on most published projects through September 2026.
