Preconstruction Impact at Scale
Trusted by construction teams worldwide. Powered by our proprietary AI model trained on construction drawings.
Every drawing detail matters
Our proprietary AI, trained specifically on construction drawings, cross-references every page to detect coordination conflicts, code compliance gaps, and design errors with precise page locations and severity ratings.
Purpose-Built Construction AI
Our proprietary model analyzes your drawings across 10+ issue categories
Procore & Autodesk Integration
Pull drawings directly and push detected issues as RFIs with one click
Precise Issue Location
Every issue pinpointed with page coordinates, severity, and category
Got questions?
Everything you need to know about AI-powered drawing analysis.
Upload your PDF drawings and our proprietary AI, trained specifically on construction drawings, analyzes every page for coordination conflicts, code compliance issues, structural concerns, MEP clashes, and 6 other categories. Issues are returned with precise page locations, severity ratings, and detailed descriptions.
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.
Connect your Procore or Autodesk account with one click via OAuth. Pull drawings directly from your projects, no manual uploading needed. Once issues are detected, you can push them as RFIs back to Procore or Autodesk with a single click, complete with issue details and page references.
Our proprietary model, trained specifically on construction drawings, achieves 95%+ accuracy. A quality gate filters out false positives, and each issue includes a confidence score. The model improves continuously as more drawings are analyzed.
Construction rework costs the U.S. industry $31 billion annually. The average RFI costs $1,080 to process and takes 10–15 days to resolve. Our customers estimate $2M+ in savings by catching issues in preconstruction rather than in the field, following the industry 1-10-100 Rule.
Helonic accepts PDF construction drawings, the standard format used across the industry. Simply upload your PDFs directly or pull them from your connected Procore or Autodesk projects. There is no limit on page count or file size.
Drawing-review breakdowns, field lessons, and research for construction teams.
Practical insights from thousands of construction drawings, coordination failures, code changes, and the preconstruction strategies that are actually moving the needle.

Why Curtain Walls Leak: The Drawing-Review Failures Behind Envelope Water Intrusion
Curtain wall water infiltration almost always traces back to a small handful of drawing-review failures: pressure-equalization gaps, missing flashing transitions, and uncoordinated anchor details. Here is what to look for before the mockup test.
Read articleElectricalElectrical Room Design Errors: NEC Clearance, Ventilation, and Egress Failures on Construction Drawings
Most electrical room failures discovered during inspection are coded into the drawings months earlier: NEC 110.26 working space violations, missing dedicated equipment space, undersized ventilation, and egress paths that don't satisfy two-exit requirements.
Read articleEnergy & SustainabilityEnergy Code Compliance Errors: ASHRAE 90.1 and IECC Mistakes That Show Up Months After Permit
ASHRAE 90.1 and IECC violations rarely show up in early plan review because energy compliance is documented separately from the drawing set. The mismatches show up at commissioning, occupancy, or utility incentive verification. Here is what to look for at design.

Most NFPA 13 sprinkler design failures are visible in 2D drawing review — obstruction violations, branch line clearance, hydraulic remote area assumptions, and storage commodity-class mismatches. Here is what to look for before the design is hydraulically calculated.

Most firestopping failures are not field-installation errors. They are drawing-stage failures where MEP penetrations, UL system listings, and the rated assembly schedule don't agree. Here is what to look for in coordination.

Loading dock failures show up as truck queueing onto the street, dock levelers that don't reach the trailer, or back-of-house aisles too narrow for pallet movement. Each is decided during drawing coordination — and each is catchable in plan review.
