This permission covers building plans, if Petersen and Sons later invites you to send them. You cannot submit a document through this form, and granting this permission sends nothing anywhere today.
Treat storage as permanent. A plan set you send is kept in Petersen and Sons' private storage. This application has no delete operation, and Petersen and Sons does not remove stored documents — so nobody here can take one back out for you, and nothing here promises that anyone will.
The content goes to a third party. The drawings and the text on them, not merely the file name, are sent outside Petersen and Sons to a third-party artificial-intelligence provider, which processes the document on its own systems in order to analyse it.
Please confirm you are entitled to send it. Plan sets are usually drawn by an architect or an engineer rather than by the builder who submits them, and the title block on the drawings often restricts their use to the single residence they were drawn for. By granting this permission you confirm that you are entitled to submit the document and to have it processed as described above. If you are not certain, do not grant this permission — ask the architect first.
This permission is yours, not Petersen's. Petersen and Sons has its own separate approval to complete before any real plan is sent to the provider, and your agreement here does not satisfy it.
