"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."

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.

· 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.
