Dear Forum,
Please, what regulations apply to organising a party on the roof of a possessed building to protect the health and safety of visitors.
And what are the roof safety precautions that need to be considered before, during and after the party.
As far as I know, parties usually involve the drinking of alcohol.
Already there is a minimum of 91cm main guard protection round the roof edge.
Your response will be highly appreciated.
Kind regards,
Kenny

My first question would be "Can the roof withstand the loading?" as it probably was not designed with the holding of parties in mind...
The answer to that could decide it for you.

Thanks Alan,
This is another problem being considered but do not know how to go about it.
The building is under possession and all building documents are being prepared from sratch as the original documents could not be found. Otherwise those doucuments would have been very useful.
Please can you give guidance on how to determine the amount of load the roof is required to carry. The roof already holds a small building for water tank that holds 2 tonnes of water. This is just to explain how strong the roof is.
Further information would be gladly taken.
Kind regards,
Kenny

Possessed building?! Perhaps an exorcism would be in order first! (Sorry tejuken, couldn't resist)
;-)
Some thoughts:
Roof access usually via single width doorway and stairs, a bit of a throttle if the fire/emergency alarm were to go off, or even for guests to come to and fro from the toilets (all really depends on the numbers).
That single door - can it be easily opened if the wind blows it shut (roof access doors aren't always well maintained, the wood may be swollen or the frame warped.)
Can the alarm actually be heard up there?
Are there other fragile areas such as skylights?
Any high power telecoms or mobile phone base stations?
Beware wind factor at height and sundry items (table cloths etc) creating danger to those below.
Is there enough lighting - inc. emergency lighting?
Stewards - sober and impartial ones are the preferred option!
Are there neighbours who might be annoyed or inconvenienced - is some 'good neighbour' notification work required?
Hot work (barbie) safety precautions
Power and lighting - temporary routing, earthing and trip hazards, etc.
Beware any podium or dias or guest access to any higher levels (e.g. lift motor winding houses) which may increase falling risk or locally reduce or negate your 910mm perimeter barriers - bear in mind all these "You've been framed" dancing-on-tables clips you've seen.
Hope everyone has a good time (omce the spooks are cleared out of course)!

The questions should be Why are we having a party on the roof? and can we hold it somewhere else if it has to be outside?

Great enjoy yourself!
If you are letting children or special needs people attend [any age from 0 to 75!] make sure that they will be managed properly and as its obviously a roof that allows access the builder should have already installed adequate edge protection - check it!

Hi,
The only sure way to check the load bearing capacity would be to employ a structural engineer, if you have no existing data.

Don't fully agree with regards to edge protection.
It should be visually inspected as may not have protection around the whole roof area.
In addition it may have been installed and could be in a state of disrepair!
It's not a requirement to have edge protection .. especially older buildings as lots of architects ect managed to wriggle out of spending money in areas where access to the roof edge was required or was on an 'ad hoc' basis!
Wouldn't want to spoil the party though! Sounds like a great idea of entertaining!

A big thank you to everyone. Really appreciate the quick response from you.
@Peter, actually the roof is being converted to a garden as part of environmental sustainability plans and at the same time it is designated as a smoking area, so everyone is expected to stay within the building.It is a 3-storey building, where the 3rd floor is the roof-an open space.
@Bob and Campbell, adequate edge protection are already installed around the whole edge and in good condition.
@Ron, sorry for the scare I may have caused, I did not mean it the other way round.
@Alan, although no available documents, but the information posted on the 2nd floor of the building under the London Building(Constructional)Bye Laws 1952 says "load on the floor should not exceed 100 lbs per square meter." Does this apply to the roof floor too and is this data still effective even though Construction laws have changed overtime.
Kind regards,
Kenny

Is there any chance that an 'object' (not a person) can accidently be dropped off the building e.g. bottle, glass etc and hit somebody below?
Also,, can we come?

You cannot assume that the roof is designed with the same load bearing capacity as the floors.
If you are converting the roof into a garden, I would expect it to be assessed by a qualified civil/structural engineer in any case.
I don't think you have any alternative with this...
Sorry.

Don't forget to determine the maximum occupancy figures, as it's likely that more people will use the garden during a part, than what the garden was designed for (thereby making escape more difficult).
Emergency lighting may be an issue and in any case, this event should trigger a review of the fire risk assessment.
If you are charging admittance or for drinks, it may require a temporary events licence from the local authority

Dear forum,
I am sorry for my late response, I have been away. I want to say thank you to all for your wonderful response.
Necessary steps are being taken to get a professional structural engineer to determine the roof load bearing. A review of the fire risk assessment is set to be conducted and other information given will definitely be taken into consideration.
@ Lilian, I will get my superior informed.
Kind regards,
Kenny
