Hi,
New to the site and just after some info and undertstanding. I'll apologise now for any incorrect terminology used!!
I've had an SE do some drawings for steels etc for an extension and just wanted to understand the drawings and calcs so that I can gather a few estimates for comparison against builders costs.
The main beams (twin bolted together) 305x137x37 show a span of 5m, there's notes that beams to have 250mm load end bearings.
My question is, do I need to add the load end bearing length to the overall span for estimates thus making 5500?
Thanks in advance.
