Design professional
Also called: design professional, A/E, architect/engineer
Design professional is the umbrella term for the licensed architect or engineer who produced the design and holds professional responsibility for it. On a construction project they are the party who reviews and takes action on submittals, responds to requests for information, issues clarifications and interprets the intent of the drawings and specifications when the field runs into something the documents did not fully resolve. They set the requirements the work is inspected against; they do not run the contractor's means and methods.
Why it matters
Nearly every acceptance criterion on a job traces back to the design professional's documents — the specified product, the detail, the tolerance. When a submittal is approved or an RFI answered, that response becomes the standard the installed work has to meet, so the field needs the current answer, not a stale one.
It also fixes responsibility. A substitution or a field change that alters the design is the design professional's call to accept, not something a trade decides on its own — and that decision belongs in the record.
How it shows up on site
Approved submittals and answered RFIs feeding the inspection criteria, and any design-affecting field condition routed back to the design professional for a documented response before the work is built to it.

Knowing the term is step one. Proving it is the job.
RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
