Could you lift a floorboard or to by the window and see the condition underneath? Damp soil/rubble collecting

It's in the longer term plan* - There's no doubt all sorts of crap under the floorboards, if the other room (with the same flooring) is anything to go by.
I've already pulled out bits cement through the airbrick hole (where there was a missing brick).
I'm also aware that the concrete in the front garden abuts the cement parging, which means the DPC has been breached since forever - And which contributes to the long-term damp problem in the bay (the stone windowsill with no run-off or drip groove caused plenty of problems, but has been remedied by and large).
* Lift all the boards along the outer wall, strip the plaster (lime, with a skim of gypsum, probably with cement slapped on too at some point) up to a height of ~80cm, clear the rubble & trim any damp joists, install airbricks, move the dwarf wall away from the external wall. Rather than re-plastering, it will be cupboarded in, keeping the walls bare with a stud in front. The bay will have a seat box in it.

Has anyone here had to have their place underpinned?
Our bay window has developed worrying cracks, both inside and outside.
My guess is that there is settling going on, but I've no idea if it's because of getting wet or getting dry.
Is it a structural engineer that I need, or a surveyor? And if underpinning is required, how much of a disruption is it?
The silver lining is that we have very disruptive plans for the room anyway (stripping plaster, lifting floors etc...) but not for a year or so.
