What impact does Helonic have at preconstruction scale?
Helonic has reviewed more than 1 million drawing pages and flagged more than 2 million issues before construction, with teams using those findings to avoid an estimated $500 million in rework.
How fast does Helonic go from upload to issues?
Helonic reads the uploaded PDF set and returns coordination, code, and missing-information findings in minutes instead of a multi-day manual pass.
Upload your drawings
Drag and drop PDF drawings, or pull them directly from your Procore or ACC projects with one click.
AI analyzes every page
Helonic cross-references every page across 10 issue categories, pinpointing each issue with exact page coordinates, severity, and category.
Collaborate with your team
Share detected issues with your team, assign action items, and track resolution across drawings and disciplines in real time.
Review issues and push RFIs
Helonic automatically places issue clouds on the drawings at the exact locations. Your team reviews the issue, then pushes it back to Procore or Autodesk as an RFI in a single click.
What questions do teams ask about Helonic?
Teams usually want to know what Helonic checks, how findings get into Procore or Autodesk, and whether the AI replaces their reviewer. It does not; it covers the sheets the reviewer never reaches.
Helonic analyzes uploaded PDF construction drawings on every page for coordination conflicts, code compliance issues, constructability concerns, and 7 other categories. Each issue comes back with a description, why it is a problem, a recommended action, and precise page locations.
Helonic detects 10 categories of issues: coordination conflicts, code compliance violations, missing information, structural concerns, MEP clashes, fire safety gaps, accessibility issues, constructability problems, dimension discrepancies, and QA/QC items. Each issue includes a severity rating (low, medium, high) and exact page coordinates.
Helonic connects to Procore or Autodesk Construction Cloud with one click so teams can pull drawings from existing projects without a manual upload. After analysis, findings can be pushed back as RFIs with issue details and page references.
Helonic's models achieve 90%+ accuracy on validated construction drawing issues. The product is built to support professional review by surfacing likely issues with page references, clear context, and recommended next steps so teams can verify and act quickly. Accuracy can vary by drawing quality, discipline, and issue type.
Helonic finishes most drawing analyses in 30 minutes. Teams that used to spend days on markups and design review meetings can find the issues in a drawing set in a matter of minutes.
Helonic customers estimate $4M+ in savings by catching drawing issues in preconstruction rather than in the field. Construction rework costs the U.S. industry $31 billion annually, and the average RFI costs $1,080 to process and takes 10 to 15 days to resolve.
Helonic works with PDF construction drawings. Simply upload your PDFs directly or pull them from your connected Procore or ACC projects. There is no limit on page count or file size.
