2x6 strength

If we’re going to try to engineer a solution, I think we need to know a little bit more about how the weight will be distributed across the resulting beam, how the beam will be supported, and (here’ s the difficult part) what dynamic loads will be placed on the beam in the process of moving it.

And how much flex the building can withstand, because flex strength and breaking strength are vastly different.

I mean you can plug numbers in to the AWC wood span calculator all day, and 7 tons isn’t that much weight, but there’s a lot of assumptions that’d have to be made here to figure anything out.

Are you talking about moving it down a public roadway? If so, you had best check on permits to do so. If you do it without you will be responsible for any damage done to the road, the right of way or the private property boardering the movement.
The DOT also takes great pleasure in stopping illegal movement and will slap you with so many fines that it would be cheaper to buy the property where the building is.

That also means you aren’t going to use a span of 2X6 to move it, you’ll need a real company with I-beams and dollies.

The good part of this is that you could take the building apart and as long as the widest part is no wider than 102” on a main road, you should be fine.
