Cracks under Steel Beam

[noseall]

Your son should ask for the calcs. Publish them here if you like, I'm sure someone qualified or at least experienced could comment.

Chat GPT: make a page full of complicated equations relating to a 10m long beam in a building...

It's not difficult to baffle with bull!

What is the end bearing length and pad stone size?

BC don't check calculations, they just file them.
Get hold of the calculations and call the SE yourself to check they're genuine.
Then if in doubt have them checked by your own SE.

The builder was asked for the SE calcs following the BC visit, nearly 2 weeks ago, and despite regular requests still has not provided them. He has been on-site and commented "I'm dealing with the calcs and am confident everything is OK" We will continue to request the calcs and see what BC say when/if they see them.

There has been no further movement or cracks since.

In the meantime, I think it would be prudent to have another SE do some calcs and see if they agree with the builders version.

The property is in Manchester, and the issues raised relates to the beams & padstones supporting the flat roof extension and full width bifold doors as shown on photos posted earlier and the queries raised.

If any SE on here wants to quote send me a msg, they will need to go onsite to see the beams and padstones currently in place and do their own measurements. The original house walls are still in place, there has been no knock-through yet. Obviously we expect to pay for these 2nd set of calcs.

Why not call back the SE your son engaged so he can look over the work done so far and give his opinion?

Across the middle of the extension is this huge beam which is supported on a steel "I Beam" in the wall. I assume it is OK like that without needing Padstones underneath ?

The bottom of the supporting "I Beam" is proud of the wall on both sides. Should it be flush ? My son thinks it's OK as Dot n Dab plastering will cover it, but I am tempted to tell the builder to angle grind the bottom flush with the wall.

WDYT ?
Thanks

Is this an attempt to hide another short beam?

Probably. Crikey, that photo looks ridiculous. It's not even new, it's demolition waste.

This builder must not be on site any longer. Do not trust anything he says, get everything checked.

I'm still concerned that billm sounds like he has some remaining respect for this muppet.
