This afternoon, a home inspection done on a townhouse. The inspector pointed out this crack in the basement situated directly beneath the staircase on a shared party wall adjoining the adjacent unit. It's a singular vertical crack extending continuously from the underside of the upper stair stringer/framing down to the floor slab. No additional cracking was observed in any other exposed or unfinished structural sections of the property. Moisture meter testing across all adjacent finished wall surfaces returned normal results, indicating no active hydrostatic pressure or water ingress. My question is: would a crack like this be a cause for concern or deem the structural integrity compromised? Thanks in advance for your insight

I started digging the footer for my 400sqft extension according to plans. Current home is on a mono slab, planned to do the same with extension.

Unfortunately, when digging the footer, I discovered that a sewer line runs through part of the footer. I've reached out to my engineer without response - not sure if he's MIA or just busy - but curious if I'm going to have to modify the extension to reduce it by a foot or two (18/19x20) or if there are alternative options. A builder-friend said that I might be able to use a sleeve. But I imagine that'll be similarly problematic given that it would be in the way of rebar.

Obviously, I'm going to rely on my engineer, but wanted to prepare myself what to expect by asking Reddit.

sorry I know this photo is awful. I’ve noticed this crack under some wallpaper in an upstairs bedroom. I’ve read step cracking is a worry. It’s about 10 inches below the top of the wall and to the right is a window. The plaster to the right does sound a little hollow if you tap it but solid around the crack. The House is 1960s and I think it’s still original plaster. This is an end wall that does get a fair bit of sun. I’ve peeled back the wallpaper a little and can see a tiny crack but it does stick out a bit. I can’t see a cracks in the wall outside.

For context, it is a 1900s terrace house.

The reason I am asking is because I have been told conflicting things - the survey says it is a problem but another company said it is fine.

Is anyone an expert or roofer who could tell me?

EDIT:

See my comment showing photos from the outside apparently showing "Dishing" of the roof.

In answer to some comments the roof has apparently been like this for 10+ years according to the agent, and the roof was partially replaced due to a fire. I do not have any evidence for this.

Hey legends trying to expand my scaff knowledge Does anyone have a document or point me in the right direction from specific rating for beam(girder) clamps how the load rating changes with different forces applied to them.
Photos examples of side loading beamies
I’ll add some photos for sort of what I am looking for
Even better if the document references Australian standards
The does and Donts with using them spuring back
Also swivel beamies
Any help would be greatly appreciated

Good afternoon looking for input, fixer upper, this section of cement block wall was removed long ago and these 4x4 where put here for some reason, 10ft space running parallel with trusses doesn’t appear to be structural as it’s only attached at the top with a couple nails, wood flexes with little effort and was covered with thin wood sheeting, most likely decorative but any input or comments would be appreciated…. Thinking of removing the 4x5s and finishing the concrete wall sections properly, wall space removed was about 10 feet maybe a little less.

concrete beam is fixed, has hairline cracks at the middle 3rd, from one side to the other, about 0.2-0.3mm on the widest where a thin business crack may fit. is this concerning? no flooe above. just ceiling and roof.
