What Will IT Block in an AI Drawing Review Rollout?
Helonic is an AI construction drawing analysis platform for preconstruction teams getting an AI drawing review tool past IT. IT will block an AI drawing review rollout when the vendor cannot answer five questions in writing: where the files sit, whether they train a model, how long they are kept, whether login runs through SSO, and who opened what. Preconstruction can ask those questions first and save a month.
Direct answer. IT blocks Helonic or any drawing review vendor that cannot name its hosting and subprocessors, state in writing that drawings do not train models, give a retention and deletion term, support SSO for a company rollout, and keep named accounts with an audit log. Each is a document, not a promise on a call.
Which answers end the evaluation?
| Blocker | Why IT cares | What to ask the vendor for |
|---|---|---|
| Cannot name where files are stored | Confidential owners require a known host and region | Hosting provider, region, and the subprocessor list |
| Vague answer on model training | Drawings could end up in a model other customers use | A written statement that customer data does not train models |
| No retention or deletion term | Files outlive the project with nobody responsible | A retention period and deletion with written confirmation |
| No SSO for a company rollout | Leavers keep access and passwords get reused | SSO or SAML support, and which plan includes it |
| Shared or personal-email logins | No record of who opened which set | Named accounts on company email with an audit log |
This is the short list of deal-breakers. The full list of setup tasks is in what IT needs before an AI drawing review, and how to read the vendor's answers is in what a security questionnaire should get back.
Does SSO have to be on before the pilot?
Usually not. A one-project pilot can run on named company accounts if IT writes that exception down with the job, the people, and an end date. A company rollout without SSO is where IT draws the line, because leavers keep access until someone remembers to remove them.
Helonic's pricing page lists SSO and SAML on the Enterprise plan. Ask any vendor which plan includes it before the pilot ends, so the rollout price is not a surprise.
What does Helonic publish for IT?
The security page states SOC 2 compliance, TLS 1.2 or higher in transit, AES-256 at rest, multi-factor authentication on critical systems, and audit logging. The AI policy states that customer data is not used to train or fine-tune AI models.
Public pages start the conversation. The contract ends it. Ask for the SOC 2 report or summary, the subprocessor list, and the retention term you will sign, then match each one to the agreement. What happens to the files at the end is covered in what happens to drawings when the subscription ends.
How does preconstruction avoid the block?
- Tell IT the day the demo is booked, not the day the pilot starts.
- Forward the security page, AI policy, and subprocessor list in one email.
- Ask IT which of the five blockers applies to this job's owner.
- Pick a pilot set whose owner terms IT can approve quickly.
A hospital or justice package is a slow first pilot for this reason, as covered in which bid package is a bad first pilot.
What will IT not block?
Whether the findings are any good. That belongs to the person who scores the pilot. IT approves the upload risk, and the product itself is judged on the set. What the product reads is on AI document review, with category background in AI for construction drawings and how to review construction drawings.
Practitioner insight
“We killed one vendor in a single email. I asked what region the files were stored in and got back 'the cloud, fully secure.' That was the end of it.”
