Gym

[jasper]

I have been to visit a premises today that is a two storey gym (health club); upstairs is open plan with two exits, downstairs is reception two changing rooms with saunas, two sunbed rooms and a small workout room with the whole ground floor having two exits.
The problem is regarding compartmentalisation, unfortunately for them some of the grid ceiling tiles were missing and looking up there were holes in the ceiling above, so on this point would the 30min clipped ceiling tiles suffice? or could this be overlooked if an L2 fire alarm system was installed?
secondly as it is all the same purpose group should the sunbed rooms and changing rooms be totally enclosed i.e. fire resistant construction?

p.s. the gym is 14m x 24m

First things first - Terminology

Compartmentation not compartmentalisation

and

Fire resisting construction not fire resistant construction (although some more modern texts now use both - because the authors have not been brought up properly)

In a two story building you would not expect any compartment floors. But the floors should have some structural fire resistance.  The 30 min clipped tiles are probably there to do that (I hate these things cos people don't realise why they are there).

The holes should be at least filled with something to restrict smoke movement (in my view - but it depends how you look at it) gob them up with some rockwool or something. (that'll get the pedants fuming)

sorry about the typo's mate, I typed in compartmentation and it auto changes it

Yes - spell checkers are not au fait with correct fire terminology. Bain of my life.

As wee B says unless its a large building over 2000 sq m it will be a single compartment. And as such could have an open light well or staircase or atrium in the middle of the floor if the designer had wanted, so long as the floors walls and roof dont collapse within an hour of a fire starting.
