If so they’ve been doing it non stop since August and at volumes loud enough to create 106dB pressure waves in my walls

We’re back on this goofy stuff again. At least we have a reference reading.
Offline is the reference measurement without a geophone attached (basically circuit noise).

I’m sorry you’re having to go through this.
I’m also really interested in this … it’s like an old-fashioned Hardy Boys … "The Mystery of the Vibrating House".
Thank you for sharing the journey, and I hope sharing it is helping your sanity.

I’m so tired, and tired of all this
Threw a bunch of relevant websites at Claude, came up with a comprehensive plan. Now a Claude-bot is churning out emails & snail mails - contacting the local and provincial government, potential lawyers, etc. while tracking and managing the whole thing.
It’s all terrifying. “I want to see your manager” as a service (IWTSYMaaS). It’s not 100% automated, but I did setup a python email pipe and a dedicated address so it can send/receive/propose replies (and send with my approval).
Hiring professionals was a good call!
I am not an engineer, but I have hands-on experience with setting up confocal and super-resolution microscopes in various labs and locations, some which were not designed for this kind of work. Exhaust fume hoods (i.e. powerful fans), floor centrifuges and powerful compressors were usually the main culprits, but not sure how these would apply to this building.
Moving, if at all possible, might be the easiest long-term solution…

Or an illegal lab of some sort.
Of note: I used to ride my bike trainer in the evening in my apartment, and that annoyed my below neighbor, big time. So I built an isolation platform on four large springs (each rated at 100 lb or so) and placed the trainer on it >>> the problem went away.

This is why I’m surprised there’s not more interest by zoning enforcement to have a look.
There are two types of this sort of activity in these parts. One steals electricity, vents out big filters in the roof, and is prone to fire. The other vents/discharges waste into the municipal sewer and is prone to explosion. It’s not as common as house prices have gone up, but I still see it in the paper on a regular basis.
We’re ~5m below sea level. There’s lots of pumping infrastructure around. It has this whurr-whurr-oosh rhythm to the vibrations, similar to the dewatering pumps used to keep the work sites dry while canal walls are replaced. Occasionally there’s a knock like a rock going through a pump or an pump fin fragmenting/knocking.
That’s my conclusion. I’m stuck here for a couple more months, but then the only option at this point is to move.
