No permit will be issued for the construction of a
building which is to have a total floor area in excess of 10,000 square
feet until an affidavit is filed with the Building Department certifying
that the construction of such building will be supervised by a professional
engineer or architect licensed or registered in the State of New York.
The affidavit shall be signed and sworn to by the engineer or architect
who will supervise the construction of such building and shall have
his professional seal affixed. In the event such engineer or architect
shall, for any reason, discontinue his supervision of the construction
of the building at any time prior to the completion, he shall immediately
notify the Building Department of such fact, and thereupon the building
permit issued for such construction shall be suspended and no further
work shall be done thereunder until another such affidavit shall be
filed with the Building Department certifying that supervision of
the construction has been resumed by another or the same engineer
or architect.
