Swiming Pool On Stage

Recommended Posts

I don't have the bible to hand at the moment so if someone could help me out??

 

We have some AMDRAM's in this week and they want to build a swimming pool type thing (complete with water) on stage, they actually swim in it too.

 

We know the stage can support the weight of it, but what are the H&S implications of having this in a show??

 

Cheers.

Are they planning to use a proper pool or just a paddling pool type thing?, as these are emptied by opening a valve in the bottom and letting the water drain into the ground. So they would be difficult to empty onstage. Although I imagine all swimming pools would be without plumbing them in to a proper drain.

pool is 16 x 8 foot, no lights on stage, but rigged above, trimmed at 8 meters above stage level.

 

My biggest worry is the stage level plugs in either wing, but we have been asured that they will be covered and won't be put anywhere near anything remoly damp.

There's all sorts of problems going on there... Swimming pools are specialist things, purpose-built. It's going to be difficult (and expensive) to achieve this onstage. Not impossible - people have done shows with water in before, but I would suspect it's beyond Am-Dram budgets. Having done a show involing circus trapeze and a water tank (simoultaneously!) I remember it's a nightmare. And our water tank was only about 6 inches deep!

 

Warning aside, some stuff to think about:

 

How are you going to keep the water clean? (So that it's safe to swim in?) Most proper swimming pools use chlorine, but you need someone properly trained to handle the chlorine and do the correct solution.

 

Are you 100% positive you can fit that kind of weight on stage? 16x8x1m is going to weigh about 1300 kilos for the water alone (never mind the structure to hold it in.)

 

You need a more robust way of keeping water out of the dips than a vague promise from the company. Some kind of physical protection is in order, and probably temporary isolation while you're at it.

 

As a previous poster says, how are you going to empty the thing? And, how do you plan to heat the water each day to a sensible temperature?

 

There's probably more...I'm sure this will do you for now..

Sorry, I didn't explain well enough. They are performing in our studio theatre, the pool is going to be on the floor with steel deck built up around it.

 

The pool in question is a semi hardshell thing complete with a pump and long tube for draining.

 

I am not connected with the AMDRAMS, I am present in a supervision roll only. Therefore, technicalities about keeping the water clean is surely their problem??

I would have said that if they're doing it in your venue, then it's your problem too.

I agree totally with bryson there, they are using your venue, so you are equally responsible for what they do, as it is on your head if they do something wrong, you will get the blame for not inspecting...

Most pools use chlorination tablets to add chlorine to the water and so keep it safe in terms of biological content, with this you will also need a test kit to ensure the water contains the correct concentration. You will also need to look into COSHH regulations regarding the use and storage of the chlorination tablets.

 

The studio will need to be ventilated to reduce the build up of excess humidity.

 

You will probably need to cover it at when not supervised in order to prevent people falling in ñ I have worked at a sports centre where we had to cover the pool at night in case somebody broke in, fell in the pool and was unable to get out.

 

128 cubic feet of water is a lot; filling it from a hose pipe will take ages as will heating it. There is probably a minimum temperature the water should be, especially if any of the performers are in a union :)

 

Steeldeck is slippery when wet! At least ours is, some kind of friction coating/matting may be required.

 

Clear marking of the edge of the pool will be required unless the base and walls of the pool contrast with the steeldeck. It should also be visible in all lighting states and if fog/haze is being used.

 

Quite a lot to think about reallyÖ

 

EDIT: spelling

Thanks for all that guys: I have a production meeting tomorrow morning, then the get-in on wednesday, I think I'll be quite busy.

 

The humidity is something I was thinking about, surely movers and water vapour don't go well... Any recomendations to protect them that dosn't involve plastic bags or relocation? (they are rigged a good 5 meters away from the pool)

Depending on your venue and any existing ventilation it may not be to bad but try to keep the movers on as much as possible to keep them warm and stop water vapor condensing on them. Simply stoping condensation will not solve all your problems and you may need to hire in dehumidifiers depending on your venue.

 

Oh and I would just like to add that I am no expert and although I worked in a sports centre I was a climbing instructor and didn't work on the pool.
