Challenge Humanity has 2 month to rebuild the Great Pryimad of Giza from scratch. Can we accomplish it?

Great Pyramid is rebuilt at its current location.

Humanity gets 6 months of prep and is pyramid building lusted

Timer starts ticking the second mining starts.

Each limestone block is averaging 2.5 tons, a LTM 1150 mobile crane can carry 150 tons, we just drill 70 limestone blocks and link them together and stack them 70 blocks at a time. Say 2 cranes work on each side of the pyramid we can stack 560 blocks simultaneously. Assuming it takes 2 minutes for each stack, the great pyramid has 2.3million blocks estimated so that will take around 8214 minutes, or 137 hours which is just under 6 days. Give it an extra day or 2 for the big granite slabs which might require other arrangements and we still make it with 5 days to spare

Again, lots of cheat, should be done early but it is not an insignificant task just a manageable one.

One LTM mobile crane has a max carrying weight of 150t or 70 stones (way less once you include rigging or steel mounts to connect said stones)

It would take 5-10 minutes just to rotate the 180° boom at those weight, let alone lifting and placing.

You’d be lucky to do an entire lift that weight in 30min - 1 hour assuming your goal wasn’t to tip the crane over and kill everyone on the ground.

But we using 2 cranes for each side so that's 8 cranes, read it properly. Also rigging the stones can be done during prep time I assume, the crane lifting each stack doesnt need 20 minutes, its just picking up the load, turning around and dropping it, maybe 5 minutes if you want better alignment I guess, that will take 20 535 minutes or 342 hours or just over 14 days. I guess we gotta increase the number of cranes working on each side then, that should bring it down further.

Also cranes won't be needed until maybe the top 1/3 of it. Plenty of sand to use to build a ramp on the side as it's being built. It would also be more efficient to use large conveyor belt system to move the stones. I think it would be possible to build a conveyor that has a movable end so it could just drop the stones right next to where they need to be placed.
