I have a small 3m x 3m (10' x 10') metal shed atop a concrete slab in my backyard. I don't like it's current position. I want to expand my backyard for my kids to play in and would like to move the shed to a corner approx 30m away. I have an old Fergie tractor (Tea20, 50+ years old and still going strong!) and access to a small excavator (Kobota with a SWL of ~600kgs) and can hire a bobcat easily if needed. My idea was to move the shed off the slab by gently lifting it up, inserting carry bars or 4 x 2" timber rails under it and getting a couple of mates to help me move it. Then to lift one side of the concrete slab and put some rollers underneath it, eg treated timber logs I have lying around, then lower the slab back on top (gently). Then to kind of nudge the slab along using the excavator or tractor or bobcat and keep moving rollers to the front, like old times (altho they didn't have machines lol). If the slab is 100mm / 4" thick the slab weight will be just over 2 metric tons (2160kgs). If it's 50mm thick, a good possibility for a humble garden shed, half that weight obviously. The alternative is to pour a new slab, move the shed, then break up and remove the old slab. It would cost about $250 for concrete, $50 for reo, $150 for a disposal bin, and a few hours of labour. Hard labour Any comments or suggestions to save me time and effort?
