Fire Cert Enquiry

professorA

Hi guys,

I have done several fire certs before, but they have been small buildings.

I am currently designing a building consisting of a boxing gym and a typical gym on the first floor. The boxing gym is 217sqm for example so with a occupancy load factor of 0.3 (assembly & recreation), that means a capacity of 724 people.

The other gym will be 62sqm divided by 0.3 = 207 people.

I just have an enquiry about the number of stairs needed for this floor and their widths?

Thanks!

the number of stairs is dependent on the travel distances available

Check your load factors, 0.3 is for a dancefloor in a nightclub, some counties will not even accecpt 0.3 for calculating occpancies. The lower the occupancy the bigger the number therefore the wider the stairs. Its not a boxing arena is it? ie with a ring and seating? I would think an occupancy factor of somewhere between 5 & 10 would be more appropiate for a training gym which @10 would be 22 persons and @ 5 would be 44. You may get away with a single stairs on those numbers wheres as with 724 you'll be looking at a minimum of three and fairly wide ones too!!

Your loading is way off there is no way a 200sq.m gym holds 700+ people

You have to use common sense also, loadings are for estiamting, but if there are other factors that affect it you are allowed to allow for them. For example, the boxing gym will have a ring i imagine. That's about 25-30 sq.m and will only have 2-4 people. Similarly, there will prob be a heavy bad area, a 10x10m area might onlt fit 8-10 bags, and therefore 8-10 people.

Cardio area tend to have a higher loading, followed by weights, then boxing/MMA.
I say actually occupancy can't be much more that 30 tbh.


I'd use soemthing like 40 and 20 for each gym, dependign on use. You could prob go a bit higher before the stairs or similar needed to change

Its for one boxing ring (6m X 6m). Can be a head scratcher sometimes.

Thanks guys!

Even bigger than i suggested, I was being cautious as it mgiht have been a smaller ring for training.
I'd be pretty confidant with my 40 people estiamate. At what point do the staits etc need to get bigger, I ahve 50 in my head but its a long time since I did this stuff.

For something so highly specialised as a gym, especially a boxing gym. Just ask the owners or guy running the place what is the max number he'll expect to have in the place.

Bare in mind, if he intends to have exhibition bouts in the gym, then it needs to allow for this and its basically becomes dual use with the spectators loading taking priority on the fire cert.

If its for a boxing ring with seats for spectators around it, you can calculate the occupancy by doing a seating layout in compliance with BS9999, (I havnt used BS999, it used to be BS 5588 part 5 but I think its all gone into this one) with the correct aisle widths and you can work out the occupants based on the numner of seat, plus 3 for the ring!! If its a training gym as mentioned aboe it will have a far lower occupancy, keep it under 50 and you may be able to get away with one stairs!!
