RE CEIVED
BL)ILDING DEPT.
It appears that the original drawing's Door Schedule for this project was in error by indicating
one hour rated doors in a corridor with one hour rated walls separating the corridor from the
office/tenant spaces. These doors should be 20 minute rated doors as per the 2006 IBC,
A one hour rated corridor requires a 20 minute rated door per the 2006 IBC Table 715.4
Type of Assemble 1 hour rated corridor walls has a minimum fire door assembly = 1/3 hour.
The glass in the door shall be rated the same as the door per IBC section 715.4.3.2.
If you need addition information to make this revision to the door schedule please let me know.
Sincerely,
