Can this be revised to the standard factor of 0.20 inches per occupant? Based on the occupant load and egress capacity provided, it does not appear that the additional capacity from using the reduced factor is needed. Leaving the 0.15 factor on the drawings may cause the AHJ to require a voice evacuation system. Please confirm if the drawings can be revised to use the standard 0.20 factor. If the 0.15 factor must remain, please confirm wheter a voice evacuation system will be required.

Revise the egress-width factor on G003 from 0.15 inch/occupant to 0.20 inch/occupant for doors/corridors. The project does not need the reduced factor for capacity. The revised factor does not change the adequacy of the indicated egress widths. No voice-evacuation system is intended solely as a consequence of egress-width sizing.
