uneven ground- digging out question

[sh40]

Im looking at putting up a 63ft x 40ft machinery storage shed. It is going in a place where the ground needs to be built up a fraction as this is the ideal place for the shed to be situated. The rest farm buildings end at this site where the new shed is going to be put up and there is roughly a two foot drop where the new shed is going. The door will be at the 40ft side of the shed. Now roughly speaking the drop will be two foot in the middle of the door. At one side of the 40ft side, the drop will be only 1ft and at the otherside of this same 40ft side will be a 3ft drop. I fear im not explaining this very well but anyway.


When I remove the topsoil. I am still going to have this uneven slope. What is under the topsoil is very fine subsoil. You wouldnt reach shale or rock too easily without digging deep. Would I get away with a cut and fill job? As in taking material from the 3ft side to bring the 1ft side up so everything is at 2ft below the rest of the yard level or will I have to dig the 3ft side down to 1ft to get the whole thing level and build up from there?

In order to rise the ground I am going to have to buy in the material as I dont have anything suitable myself. I know I will have to buy in a share anyway but want to reduce as much buying in as possible.

Edit: I should have mentioned the shed will be 16ft to the eves and I need to keep as much height as possible.

Depends what you want to do with the finished floor, if you want to concrete it straight away you'll need to get a bit more serious with the job, if i were you i'd just remove topsoil and get some quarry waste in there and let it settle for a year, that would be your cheapest way out,

Yes I can leave the concrete floor for a year until it settles but obviously am hoping to get the shed up in a month or two.

It would be fine if you properly compact it after. 120 or 135 roller on very slow passes with 1 ft layers doesn't leave any voids.

Strip top soil put some Crush down to keep it clean then dig leg holes. Concrete holes with cones where ever legs fall level wise. Get shed company to come with laser level and make legs length to suit. Fill up floor to where you want it when shed is up and leave for a year or two then concrete.
