Concrete prefab, base size. - Have i mucked he size up?

[MRRB]

If anyone can answer this I will be most grateful because I am in a horrible panic.

Nominal 6000mm by 5000 mm prefab garage for use as garden shed (by my measurements it will be 6020 by 5035 actual).

Slab is 6050 by 5050.

Have I mucked it up and made it too small to use?


The "Plain ConcreteHardstanding" section of the main website suggests at leasat 150mm between edge of slab and garage structure. I've got 10mm, give or take.



DATA (if required):

The edges (keels) of the slab are 200mm deep, 600mm wide, all around, changing to 100+mm in the middle, with A142 mesh.

Corner post weight 100kg, side post weight 70kg, section weight 36kg each 4 sections per bay so 144kg/bay. 6 bays per side 5 bays for back.

Therefore weight of concrete structure each side is ~1414kg, back is 1160, front will be much less because mostly 4 x side-hinged doors, roof structure will be angle iron + Sterling board + corrugated iron.
