Some thought gone into that...
Yep... There ya have it folks... Takes the term 'raising the roof" to a whole new level! Raising a roof smoothly requires the right equipment and expertise.… | 125 comments on LinkedIn

and some work ... all done with chain blocks and a lot of guy lines I'd guess, BTLs....
did something similar to that in the 90s ... built a new steel frame for the new MRI and CT suite in the local hospital on the flat roof of their A&E dept. .... main contractor set all the datums, my structural and I designed the frame work and detailed it to their datums. Fab.ed it, erected it, got signed off. They roofed it, built all the brick walls around it ... Siemens' guys came to measure up for the lead lining in the CT area and ....... call from main contractor 20th December - (I'll never forget the date) - roof is 650mil too low ...
.... "
Help - what can you do for us "
went and met their guys - we'd been off site for months - with my structural, who fair play had dropped everything to come that day ... transpired their piss head of an agent had forgotten to add the 600mm, to cater for the concrete upstand of a roof light in A&E, to which the new false floor was to be set .. floor framing in - roof too ferkin' low
by Christmas eve, we'd fab.ed a load of new stub col.s, had an Acrow forest in place under the roof, guy lines every where to keep it from swaying about on them, as it went up and it was ready for a lift on the 28th. Was a long day, but we had it up, new stubs installed and dogged and the roof re-secured to the surrounding structure by the end of the day.
Then I had to fight the ba**ards for months to get paid for getting them out the sh1t .. outfit called Genesis Medical ... never got it all, but a shortfall compromise was better than chucking yet more money at it ........ and I more than made up for it on their next job
somewhere I will have a lot of pix of it all.
