Post by: PaulT on March 27, 2008, 09:43:46 AM

Is there a simply method for calculating the maximum numbers of persons who can occupy a floor and building.  The information refers to general office space.
Any answer appreciated.

Start with AD pt B, purpose groups, then the table for occupancy/floor space factors.

Look at the LCLG Guide number 1 for Offices and shops.  Assign a risk category as detailed in that document, measure the opening widths for the doors and look at the tables.  A 700mm door will allow X number of people dependent on the risk you assign.

CLG guides are a free download from www.communities.gov.uk  You need the means of escape section in part 2.

Help,
When opening a night club is there a rule for the number of compulsary toilets related to capacity?

Judita, I think you are asking the wrong forum this question.

Hi Judita

In asnwwer to your question yes you should have a set ammount of toilets available related to capacity.

However Im sure what the facts and figures are - you would need to approach your local environmental health department for guidance

Judita, have a look at BS 6465-1:2006 - Sanitary installations. Code of practice for the design of sanitary facilities and scales of provision of sanitary and associated appliances.
