"This is a game-changer for preconstruction. We ran a set through Helonic and it caught three major MEP clashes our team had missed after a week of review. It paid for itself on day one."

Mark C., Preconstruction Manager · June 2026

"The Procore integration is seamless. Going from an AI-detected issue on a PDF to a formal RFI in Procore with one click saves me so much administrative time. It's brilliant."

Jenna S., Project Engineer · May 2026

"A very powerful tool for QA/QC that significantly speeds up our internal review. It's not infallible—it still requires professional oversight and can be sensitive to the quality of the scanned PDFs—but it gets us 90% of the way there in minutes."

David R., Senior Architect · June 2026

"We use this on every project now. It's our safety net. The ability to do a full coordination check on 2D drawings without needing a BIM specialist is a huge advantage for our team."

Comparison

How it compares

Helonic vs. Autodesk Navisworks: The choice depends on your source files and workflow. Choose Navisworks for comprehensive, multi-disciplinary 3D model-based clash detection and simulation within a BIM ecosystem. Pick Helonic when your primary deliverables are 2D PDF construction drawings and you need a fast, automated way to find coordination issues, code violations, and constructability problems without the overhead of creating or managing 3D models. Helonic excels at making 2D plan review intelligent and integrating its findings directly into RFI workflows in Procore and Autodesk Construction Cloud.

When you need automated issue detection, not just digital markup tools like Bluebeam.

When you work primarily with 2D PDF drawings and don't have or need 3D models for clash detection.

When you need deep integration with Procore and Autodesk for a seamless RFI workflow.

Who It's For

Why Construction & Civil Engineering Excellence choose this tool

🎯

Built for

This tool is best for construction teams looking to automate 2D drawing review to catch preconstruction issues and reduce RFIs without requiring 3D models.

In-Depth Overview

Helonic directly addresses the multi-billion dollar problem of construction rework by automating the preconstruction drawing review process. Instead of spending days manually redlining drawings, your team can upload a PDF set and receive a comprehensive analysis in minutes. The platform's proprietary AI, trained specifically on construction drawings, boasts a 90%+ detection accuracy across 10 critical issue categories, including MEP clashes, code compliance, and structural concerns. The proof is in the workflow: Helonic has analyzed over 100,000 drawing pages, flagging more than 150,000 issues and helping customers avoid an estimated $30M+ in rework. Its key advantage is working directly with the 2D PDFs you already have, eliminating the need for 3D models. One-click integration with Procore and Autodesk Construction Cloud allows you to pull drawings and, more importantly, push detected issues back as RFIs, seamlessly connecting AI-driven insights to your project management system.

Key Use Cases

90%+ clash detection accuracy

✓ Pros

Finds issues in preconstruction, saving significant rework costs.

Analyzes 2D PDFs directly, bypassing the need for 3D models.

Seamlessly integrates with Procore and ACC for pulling drawings and pushing RFIs.

Detects a wide range of issues across 10 categories, including code compliance.

Fast analysis completes in minutes, drastically reducing manual review time.

· Cons

Pricing is not transparent and requires a sales demo and custom quote.

Accuracy, while cited at 90%+, can vary by drawing quality and discipline.

Primarily focused on 2D PDF analysis, not a full replacement for 3D model-based clash detection.

Effectiveness is dependent on the quality and clarity of the uploaded PDF drawings.

⚡ Editorial Verdict

Helonic provides a powerful, practical way to de-risk projects by automating the tedious process of 2D plan review. Its ability to find clashes, code issues, and missing information directly from PDFs is a major time-saver. The main trade-off is the lack of public pricing, which requires a sales demo to get started.
