Occupancy levels in buildings
« on: June 15, 2009, 09:10:50 AM »
Hi all, :'(

I was wondering if anyone could give me some advcie on occupany level calculating for my studies, I'm gettung a little confuesed reading the different regs such as Part B and BS5588, and struggling to give a difinative calculation method. the quesion i've been asked is below and i'm struggling to find a clear calcution method...please can someone help...the question roughly translates as follows

Consider the following;

"if a floor level of 7500 sq ft and Its on the 8th floor of a 21 storey building of concrete construction with excellent compartementation throughout,  the client needs to house up to a maximum of 250 students, its for a training centre i.e mainly classrooms, it has two main protected fire staircases 1400mm wide with handrails both sides.  the floor has 2 x double doors exits  and two single door exits , these lead onto a protected lift lobby in the core of the building and then the two protected fire escape routes run of this lift lobby. Currently  there is about 2000 occupants in the building with 10 diferent tenants, the fire strategy is a full evacuation not phased

when considering you answer, what advice would you give the client on there need to have 250 students  based on the above information what would be a sensible figure as a guidance to your clients to allow them see if the building is suitable for there needs or if any other consideration could be used to increase  ocupancy levels"

It apppears to be a question related to Approved document B and the capacity of exit doors and staircases. Take a look at page 37, 44-47 of approved Doc B  2006 edn and if you get stuck come back to us.
