AI construction document review: drawings, specs, and schedules checked together
Helonic is an AI construction drawing analysis platform for teams running QA/QC on construction drawings and specifications.
Most document errors are not on one sheet. They sit between documents: a door schedule that disagrees with the plan, a spec section for a product the drawings never show, an addendum that changed one sheet and missed three others. Helonic reads the whole package at once and lists those conflicts, each tied to a sheet and spec section.
Direct answer. Helonic is an AI tool that reviews a construction drawing set, its schedules, and the project manual together and flags where they conflict. Design teams run it as QA/QC before issue, and GC preconstruction teams run it before bid. Each finding cites the sheet and spec section. It does not review contract terms or generate documents.
What is AI construction document review?
AI construction document review is software that reads the drawings, schedules, and specifications of a project as one package and checks them against each other. A person reviewing sheet by sheet catches errors on the sheet in front of them. The expensive ones are the cross-references, and there are thousands of them in a typical set.
Helonic works on the 2D PDF set and project manual that actually get issued. It does not need a BIM model. The reviewer still decides what each finding means and what to change. For the broader topic, see AI for construction drawings.
Which documents does Helonic read together?
Helonic reads the drawing set, the schedules, the specifications, and any addenda, and checks each one against the others.
| Document | What Helonic reads | Checked against |
|---|---|---|
| Drawing set (architectural, structural, MEP, fire protection, civil) | Plans, sections, details, callouts, keynotes, and general notes | Every other sheet in the set, the schedules, and the specs |
| Schedules on the drawings | Door, window, finish, equipment, fixture, and panel schedules | The tags and counts on plan, and the spec sections they reference |
| Project manual (CSI MasterFormat specifications) | Products, materials, performance requirements, and reference standards | What the drawings actually call out and note |
| Addenda, ASIs, and revised sheets | Clouded changes and revised spec sections | The sheets and sections the change should have carried through to |
Two parts of this have their own pages. Section-by-section spec checking is covered in AI for specifications review. Checking shop drawings and product data against the specs is covered in AI submittal review.
What conflicts does Helonic find across documents?
Helonic finds places where two documents describe the same work differently, or where one document points to something the other does not contain.
- Drawing vs. spec. A wall type on plan with a different gypsum board or insulation than Division 09 calls for, a product shown on the drawings that no spec section covers, or a spec section for work that never appears on a sheet.
- Schedule vs. plan. Door tags on plan with no schedule entry, a fire rating in the door schedule that does not match the rated wall it sits in, and equipment in the mechanical schedule that never shows up on the floor plan.
- Callout vs. detail. Section and detail callouts that point to the wrong sheet or a detail that does not exist, and keynotes with no matching keynote legend entry.
- Discipline vs. discipline. Duct and pipe routed through beams, ceiling heights that the plenum depth cannot support, and penetrations through rated assemblies with no detail.
- Revision vs. the rest of the set. An addendum that changes a door on the floor plan but not in the schedule, or a revised spec section that still conflicts with the original sheet note.
- Drawings vs. code. Egress widths, accessible clearances, and fire-rated assembly conditions that the plan reviewer will flag, checked against the editions the AHJ has adopted.
The detail behind these checks lives under schedule verification, detail cross-referencing, clash detection, revision comparison, and code compliance.
How does it fit QA/QC before issue and before bid?
Helonic runs at each point where the set leaves one team's hands, so conflicts get fixed on paper instead of priced or built.
| Stage | Who runs it | What it catches |
|---|---|---|
| Design QA/QC before issue | Architect or engineer of record | Coordination and spec alignment on their own set before it goes out for bid or permit. |
| Bid set review | GC preconstruction and estimators | Drawing and spec conflicts that would change price, written up as pre-bid RFIs. |
| Permit submission | Design team or permit expediter | Code items the plan reviewer will comment on, fixed before the first review cycle. |
| After each addendum | Design team and GC | Whether the change carried through to every sheet, schedule, and spec section it touches. |
The workflow is the same at every stage:
- Upload the PDF drawing set and project manual, or pull them from Procore or Autodesk Construction Cloud.
- Helonic reads every sheet, schedule, and spec section and checks them against each other.
- You get a list of findings ranked by severity, each with the sheet, location, and spec section.
- Your team confirms each finding and sends it out as an RFI, a redline, or a comment back to the designer.
Findings become RFIs through RFI generation. For a manual checklist to run alongside, see the construction drawing QA/QC checklist. Preconstruction teams can read Helonic for preconstruction teams.
What does Helonic not do?
Helonic reviews technical documents that already exist. It does not write them, price them, or read the contract.
- It does not generate documents. Helonic does not draft drawings or write specs. The architect or engineer of record makes every change and stamps the set.
- It does not review contract terms. Payment, retainage, indemnity, and insurance clauses need a contract review tool. See Helonic vs Document Crunch.
- It does not check BIM models. Helonic works on 2D PDFs. The tradeoffs are in 2D vs 3D clash detection.
- It does not do takeoffs, estimates, or design calculations. It flags conflicts that affect quantities and price, but the estimator and engineer do that work.
- It does not approve anything. Design decisions, substitution equivalency, and permit approval stay with licensed professionals and the AHJ.
Practitioner insight
“When we first ran the AI on a hospital project for a regional GC, the top finding was not a drawing error. It was a submittal that had been approved by the architect with a non-compliant fire rating buried in the cut sheet. Manual plan review would never have caught that because it wasn’t in the drawings. That’s when the team realized they needed document review, not just plan review.”
