Hello all.
First post on here but a long time reader.
I am currently preparing my calcs for building control for a loft conversion but am struggling to get a definitive set of loads to use.
I can work out the actual loads of each material and use that to calculate loads, but for the design of the floor and roof, what live loads should I apply.
In summary, the loft will contain a bedroom and a bathroom.
floor construction will be/is timber joists with lathe and plaster ceiling attached below with plaster board below that. I will be putting a T+G chipboard covering and then carpet in the bedroom and tiles in the bathroom. The roof itself is standard clay tiles (10mm?) on top of 12mm sarking board. Rafters and floor/ceiling joists are 100x50 @350 ctrs.
Any advice on sensible loads to use would be much appreciated.
I am hoping to prove that the existing ceiling/floor joists in the loft are already strong enough to be used as the floor for the new room and therefore avoid putting in steels and duplicating exactly the same floor again over the steels.
