Ok, so i've got some the measurements for the beam, it's a lot smaller than we thought. I'm pretty sure it's a JIS spec beam, 350x175x7 x11, which is 63kg per meter, so the each one weighs 725kg. I'll have to shop around but we might be able to get away with 2 or 3 Genie lifts just about if they...

Thanks for that. I'm quoting them now, and you're probably right. I thought it was worth a shot though. If we decide to use SIP panels for the roof construction, we may need a crane anyway, as i'm looking at some large panels which are over 100kg a piece, too heavy to be hauling up on to the roof!

Sorry, i probably didn't make it clear in my original post. This is a conversion (from a small storage unit to a residential building), so we're using the existing steel i-beams that support the current roof. The issue is the roof needs to be raised by about 1.6m so we need to take the original...

Yes, through a 3rd party, not through LABC. To be honest, we're still in the early stages though. Calcs will probably be needed soon, but we're doing several things simultaneously because of the project timeline. We're confident the beams are suitable, so we're trying to plan the best...

I don't have any calls for these. Because it's existing for supporting the existing roof, no one has asked for the calls for them. I am getting the beams measured this morning though, so once i know the flange thickness the weight should be easy to calculate.

Thanks for the input. It's a good idea, and we had thought about a similar idea, but the amount we need to go up, is substantial (about 1.6m on one beam, and the temporary support would need to be so sufficient, it's probably cost as much to construct as it would be to hire a crane. If we had a...

We're doing a self build which is actually a conversion of a current industrial building. It has a large flat roof which is supported by 3 x 11m long i-beams, approx 450mm x 300mm section, and they need to be raised by a few feet up to a height of around 7.5m. My question is, for a beam this...
