Which Pilot Results Mean You Should Not Buy AI Drawing Review?
Helonic is an AI construction drawing analysis platform for preconstruction teams deciding whether an AI drawing review pilot result should end the deal. Some AI drawing review pilot results should end the deal, even when the demo was good and the team liked the vendor. Knowing which ones ahead of time keeps a weak pilot from turning into a contract because nobody wanted to be the one to say no.
Direct answer. Do not buy Helonic or any AI drawing review tool if the pilot missed most of your known high-severity issues, returned findings your reviewer could not locate, or cost more review time than it saved. A reviewer who will not use it again, findings that cannot leave the tool, and failed security review also end the deal.
Which outcomes should end the deal?
| Outcome | Why it ends the deal | How to check |
|---|---|---|
| It missed most of the known high-severity issues | The issues that cost money are the reason to buy. Catching small ones does not make up for it. | Count against the filtered RFI log from the closed-out set. |
| Findings have no usable location | The reviewer has to hunt for each one, which is the job you were trying to shorten. | Open ten random findings. Time how long it takes to find each on the sheet. |
| Clearing the noise took longer than a manual pass | Every rejected finding costs reviewer minutes. Past a point the tool adds work. | Compare scoring hours to the reviewer's manual baseline. |
| The reviewer will not open it on the next bid | A tool the daily user avoids gets dropped once the pilot attention fades. | Ask the reviewer directly, after scoring, with the champion out of the room. |
| Kept findings could not leave the tool | A list that lives in one more login does not get used past the pilot. | Push one kept finding to Procore or Autodesk during the live bid. |
| Security answers did not survive legal review | Nothing else matters if the files cannot be uploaded on the next job. | Written documents, reviewed before the decision date. |
Any one of these is enough. A pilot that catches great issues but cannot hand them to Procore will still be dead in three months. Write these into the pass rule from what result means the pilot worked so the no is already agreed.
Which bad-looking results should not end the deal?
- Some false positives. Every tool has them. The question is how long they take to clear, as covered in AI drawing review false positives.
- Misses on RFIs that were never on the drawings, like field conditions or owner changes.
- Weak results on a set that was missing sheets. That is a test problem. See what breaks when the PDF set is incomplete.
- A reviewer who disagrees with the severity on a few findings but kept them anyway.
Should you allow a rerun?
Once, if the input was wrong on your side. A missing spec book or a superseded revision is a fair reason to run the set again.
Do not allow a rerun after the vendor has seen your answer key. If they ask what the tool missed and then "tune" a second run, the second score tells you nothing about the next bid. Also ask directly whether people at the vendor edit findings before you see them. Human review can be a fair part of a product, but you need to know it is there and whether it is in the price.
How do you say no cleanly?
- Send the vendor the line from the pass rule that failed. One sentence.
- Ask for written confirmation that your uploaded files were deleted.
- Revoke Procore or Autodesk access and any user accounts.
- Keep your score sheet. It is the starting point for the next evaluation.
What deletion should look like is in what happens to drawings when the subscription ends. If you plan to test a second vendor, use the same set and the method in how to compare two pilots on the same set.
Where do the buying criteria come in?
Before the pilot. The criteria in what to look for in an AI construction drawing review platform decide who gets a pilot, and the protocol in how to pilot AI drawing review software decides how it runs. This page is the short list of results that should stop the purchase.
Helonic shows every finding at its sheet location and lets the reviewer reject it in place, which makes the location check above quick to run. That workflow is on AI document review.

“The second run was way better, and then I realized they'd asked me which RFIs they missed. That told me everything I needed to know.”
