To whom it may concern,
I encountered a scenario in the hospital basement, tunnel / trench are attached to the basement (please find attached image with information for reference), Do i have to consider the maximum travel distance of 61 meters? If so it will exceed the allowable maximum distance stated in the code.Is there any stated in the life safety code pertaining travel distance in trench / tunnel? My least option would be additional staircase, if no provision for travel distance were stated in the code.
Your suggestion are highly appreciated.
Thanks and Regards,
