It is a great looking observatory but it needs a pier.
Hence the problem:- to get down to the concrete floor below, the pier will have to be 22 feet long. My question is has anyone ever done a pier this long and if so how did it work?
I was thinking of a 6" water well pipe but I think with the length it will vibrate.
I was also thinking of a 4' pier sitting on the floor but won't that vibrate just as bad from walking around?
Me thinks I should have gave this a little more thought before starting. Duh!!
If anyone has any thoughts on my problem I would sure like to hear them.
Sincerely, bob black
