Shed footings size

[sh40]

what size footings need to be dug for a 63ft x40 shed? Digging a foundation all the way around as shed will also be getting poured concrete walls at some stage.

Will the same size footing do all around the parimeter of the shed or do they need to be extra wide/deep where the Rsj uprights will be bolted to?

To make it easy for yourself I’d go 1m square at every leg and min 500mm deep. A lot depends on soil type, and are you concreting the floor after? i.e. will the feet then be buried under concrete once complete?

Is there any side load? if it is a grainstore I would go a bit deeper.

No load up against the wall , its just a machinery shed.

And what dept then between the legs? I want to put a full foundation around the perimeter? Soil is very good free draining. The very will be buried but not by much. Foundation will be laid first then rails stool, then walls poured between bays and maybe in a years time the floor will be going in at a depth of 6 inch.
