Hi Bo,
I'd prefer to get the prototype done first (which shouldn't take long) as a proof of concept. fwiw) The pier will be a tapered square hollow section fabricated from laser cut parts. The design will be acoustically dead (which I hope to demonstarte using accelerometers)
Also, there is no reason why it could not be made to enable meridian flip-free imaging within the mechanical limitations defined by any given OTA & eq head combination.
For anyone living in WA, I could install it if my costs were covered assuming there is 240v on hand for the jackhammer to put down the foundation pins.
fwiw) When I did the foundations for the shipping container, there was a pretty heavy shower went through before I got the chance to properly backfill around the posts. (I think it was 37mm of rain in 20 minutes flat) This left approximately 200mm of standing water on top of the area of clay where the pins were located with a couple of tonnes of weight on each post.
After releasing the jacks holding the weight of the container, I re-checked the laser level across the four corners. After taking the complete load of the container plus its contents, whatever amount the foundations settled was below the resolution of the laser level. They are super strong and rigid.
