Dear Mr. Poskin:
Mr. Castile would like to install the "optional" second floor area for buildings A & B.
The total occupant load for the second floor does not require that two exits be provided
(see attached worksheet.) The beam calculations and revised drawings have been
enclosed and reflect this modification.
Please call me if you have any questions or concerns regarding this matter.
Sincerely,
