Was a corridor now not a corridor

[Mr. Inspector]

CORRIDOR. An enclosed exit access component that defines and provides a path of egress travel to an exit.

Alterations being done to a medical office (B). Sprinklered. It had a 70' long exisiting corridor that ended at a waiting room that conneted to a lobby on one end. Other end has a door to a storage room that has an exit door. They want to install a wall across the corridor 30' from the waiting room that will leave 40' of of corridor without an exit. They are planing to have two 3' openings in the corridor wall on either side of the wall that will be built across the existing corridor. that lead into the same office. So a person could go down the 40' section of the corridor, walk through the office and continue back into the 30' corridor to the waiting room and on to an exit. The existing corridor is enclosed and leads to an exit. Now with the 3' openings and the 40' section not leading to an exit can it still be called an corridor or is just an aisle.

How many sq ft is the office/ business

Occupant load

Is the building sprinkled

What edition icode

 

[Mr. Inspector]

Plans only show a part of building, the tenant space which is 3800 sq. ft.. they did not give me a occupancy load but i think it would be about 34. sprinklered. 2009 IBC

 

[cda]

so they can do non rated corridors

I was going to say because of size and occupant load ,,,, sounds like they need two legal exits, but looks like they are good there

plus does common path of travel come into play???? will that require two legal exits

 

[Mr. Inspector]

They do have two but the one in the back is in a storage room. Don't know if it is an existing storage room.
