Helonic vs BuildCheck: what BuildCheck AI does and how it compares

BuildCheck (Buildcheck AI) is an AI drawing review service that screens 2D PDF drawings and specifications for errors, omissions, and coordination issues before permit, pricing, or construction. Its in-house experts verify every AI finding before results reach the client, which it includes by default, and reviews take about 2 days to 2 weeks. Pricing is per sheet with volume discounts and unlimited seats, starting with a trial project. Findings sync to Procore as coordination issues or draft RFIs, and back-checks on new revisions are free.

Helonic is an AI construction drawing analysis platform that reviews the same kind of 2D sets, typically returns results in 15 to 30 minutes, and writes findings into Procore and Autodesk as RFIs.

Should you choose Helonic or BuildCheck?

Both review 2D drawing sets with AI. BuildCheck is the better choice if you want a person to confirm every finding and can wait for it. Helonic fits teams that need speed, code depth, and RFIs in Procore or Autodesk.

Choose Helonic if:

  • You want results that typically come back in 15 to 30 minutes rather than a multi-day verified review
  • You need code checks against IBC, NFPA, ADA, NEC, Title 24, or the local edition your jurisdiction adopted
  • You want findings written as RFIs in Autodesk as well as Procore
  • You want to pull drawing sets straight from Procore or Autodesk instead of uploading them
  • You want spec, schedule, and revision checks in the same review as coordination

Choose BuildCheck if:

  • You want a person to verify every finding before you see it, and can wait days for that
  • You prefer per-sheet pricing with unlimited seats and a trial project
  • You want a shared workspace with markups, task assignment, analytics, and free back-checks
  • Your firm wants its own design manuals and QA/QC checklists turned into checks
  • Your projects match its stated fit: $10M+ hard cost with sets at 50 to 90% CDs

What are the key differences between Helonic and BuildCheck?

Human verification versus turnaround. BuildCheck puts an expert between the AI and the client on every review, which it says keeps false positives down. The cost is time: 2 days to 2 weeks per review. Helonic typically returns results in 15 to 30 minutes, so teams can run it on every issue and revision without planning around a queue.

Workspace versus your existing project system. BuildCheck gives you its own web app with markups, task assignment, analytics, and back-checks, and syncs issues or draft RFIs to Procore. Helonic pulls the set from Procore or Autodesk and writes findings back as RFIs inside both, so the work stays where your project already runs. See the Procore integration and Autodesk integration.

Code checks against a named edition. Helonic checks drawings against IBC, IRC, NFPA, ADA, NEC, Title 24, and the adopted local edition you specify, with the sheet location for each finding. BuildCheck's published checks focus on drawing health, 2D clashes, and omissions, such as under-rated doors in fire-rated walls, and it does not publish its code scope in detail. If pre-permit code review matters, ask BuildCheck which codes and editions it covers. More on Helonic's code compliance checks.

BuildCheck publishes its own results: 10 to 35x ROI, 50% more meaningful comments than a traditional review, and 150,000+ drawings reviewed. Helonic has completed more than 1,000 drawing reviews.

Frequently Asked Questions

What is BuildCheck?
BuildCheck (also written Buildcheck) is an AI drawing review service for owners, general contractors, and architects. It screens 2D PDF drawings and specifications for errors, omissions, and coordination issues before permit, pricing, or construction, and has its own experts verify findings before delivery. Results come back marked up on the drawings in a web app where teams assign and track issues.
Is BuildCheck AI fully automated?
No. BuildCheck describes its process as expert-in-the-loop: its team checks the AI output before it reaches the client, and says this is included in every review. That is the main reason its turnaround runs from about 2 days to 2 weeks depending on set size.
How much does BuildCheck cost?
BuildCheck does not publish prices. Its FAQ says it charges per sheet with volume discounts, includes unlimited seats in the platform fee, makes back-checks on new revisions free, and starts new customers with a trial project. Contact BuildCheck for a quote.
Does BuildCheck integrate with Procore or Autodesk?
BuildCheck syncs findings to Procore as coordination issues or draft RFIs. Its general contractor page lists Autodesk Construction Cloud as integrated, while its FAQ lists ACC with Fieldwire, Revizto, and Trimble on the roadmap, so confirm Autodesk scope with BuildCheck. Helonic pulls drawings from and pushes RFIs to both Procore and Autodesk.
What is the difference between Helonic and BuildCheck?
Both review 2D PDF drawing sets with AI. BuildCheck adds human verification of every finding and a collaboration workspace, and takes days to weeks. Helonic typically returns findings in 15 to 30 minutes, checks the code editions you specify, cross-references specs and schedules, and writes findings into Procore or Autodesk as RFIs.
Is Helonic better than BuildCheck?
It depends on what you value. Choose BuildCheck if a person reviewing each finding before delivery matters more than speed, or if per-sheet pricing with unlimited seats fits your budget. Choose Helonic if you need results that typically come back in 15 to 30 minutes, code checks against a named edition, and RFIs in Procore or Autodesk.
How long does a review take in each tool?
BuildCheck says reviews take 2 days to 2 weeks depending on project size, because its experts verify the output first. Helonic typically returns results in 15 to 30 minutes.
Can I use both platforms together?
You can, though most teams pick one for routine review. A team might run Helonic on every issued set for fast coordination and code checks and bring in a human-verified review like BuildCheck at a major milestone.
