Common questions
Do consultants need a paid seat?
No. Architects and engineers are invited as free view-only guests and can reply in the discussion.
Can we upload revised drawings?
If the contractor makes you a member, yes. Many teams have the contractor upload bulletins so the set stays controlled.
Is the record permanent?
Closed RFIs keep the official answer and the full discussion, and everything is included in the project export.
