Comments:  Within this section, it would appear that a cover sheet may not need to be signed and sealed if no professional had assumed responsibility for the entire project.  It appears a statement needs to be included.  Also, should professional and professionals be changed to regulant and regulants, respectively?

B.2. For projects involving multiple sets of plans from multiple professionals involved in the same project, each professional shall seal, sign, and date the final documents for the work component that he completed or that was completed under his direct control and personal supervision. Any professional responsible for the entire project shall seal, sign, and date the cover sheet of the aggregate collection of final documents for the project.

Recommendation – add “a sentence that at least one professional shall be responsible for the entire project”.   Change "professional(s)" to "regulant(s)".

B.2. For projects involving multiple sets of plans from multiple professionals regulants involved in the same project, each professional regulant shall seal, sign, and date the final documents for the work component that he completed or that was completed under his direct control and personal supervision. The professional regulant responsible for the entire project shall seal, sign, and date the cover sheet of the aggregate collection of final documents for the project.  All projects shall have a minimum of one regulant responsible for the entire project.  This regulant(s) shall also be responsible for assembling the final documents (work) and ensuring compliance with the regulations.  When a regulant affixes his seal, pursuant to 18VAC10-20-760 A, to the cover sheet of the final documents (work), he shall assume responsibility for all work shown in the final documents (work) for which no other seal has been affixed.
