I'm in a mobile hydraulic hoses emergency service, up until March I used to go into construction sites (a.o.) as well. Since we do not have Area 51 here, in Poland, I use to say that HiViz jacket set makes you invisible."

Funny you mention a raiway bridge. We have a steel one, here in Warsaw (wonderfully noisy), it's on my bucket list.

So far I bought (from Ali) such, alernative to typical piezo elements, which may be of interest for you:?

Or these:
Waterproof and easier to attach to surfaces than a typical piezo. Also doesn't require shielding.

Also:
Self shielding as well.
Havent tried these yet how they work attached flat. Will try to buid a sort of a geophone - the piezo strip clamped at one end and wieghted at the other.
