You do, all of those darker support posts you see with hoses connected to them are long st5roke hyd. cylinders doing the lifting these will be anchored tot eh slab and if you watch the right side of the screen, you can see much larger columns also telescoping. Those are lifting and stabilizing as well. Judging from the men moving about, the scale of the building appears to being altered from about 10or 11 ft clearance to 15 or 16 ftQuote:
