Sypder, Great to see its almost done, more cash to your pocket.

The function of a foundation nay "German Floor" is to transfer the structural loads reliably from the building into the ground. Building foundations pierce the earth until they reach soil or rock that is competent to carry its massive loads. The concrete slab (German floor) distribute this piercing action equitably.

Your foundation, in fact all foundations must support both dead load (structural frame ) and live loads (furnishing, equipment etc), without the German floor, you are short changed on the advantage of a good foundation which must be safe against structural failure that could result in collapse and again without a reliable load distribution mechanism which a German floor offers, your foundation stand a greater risk of different parts of the building structure settling by substantially different amount which may distort the frame of the building leading to cracks.

Hope this helps. Good Luck!

Thank you for that analysis, however I think a properly sized footing can also do that.
If for example I placed the required footing width and thickness on the soil for the structure, it should withstand the piercing or the depression on the soil (assuming soil bearing capacity is OK). I personally dont see the so called "blinding" as appropriate footing thickness in all cases and as such may go with the german flooring to augument the load distribution. But again if I have adequate linear/perim footing, pier footing or whatever, I will put my slab on grade directly, bar any other site condition though. When I put more on my footing thickness before that 4 or 5 layers of foundation wall I may eliminate german flooring. Just my give and take look of the issue.

^^^^ as Olubuffett said, N40k is cheap, but the structural and other things are also needed for approval in some localities. Mine cost only N20k but it was someones plan which the architect dubbed and I happened to like the size and style of the building.
This next building I will start by next week was drawn with N60k and it is a complete drawing, it is not strange to hear N80-N120k for just drawings, although it will depend very much on the type and size of the structure.
