Construction Technology - Restoring the Leaning Tower of Pisa
(www.youtube.com)
This is a most excellent place for technology news and articles.
It was extremely close to collapse, so they spent a DECADE researching. That’s ballsy.
It was extremely close to collapse after over 800 years. They had time, just not an unlimited amount of it. People with a lifetime of experience and education knew how to work through the issue, and had a good idea of how long they had.
They closed the area off, did some tests, and worked slowly because some of their ideas made the problem worse. You don't want to rush solutions on completely unique problems, with completely unique artifacts.
That does make sense, interesting stuff.
They did so with temporary weights or other methods like cables to make sure it didn't get worse or collapse.
It's not a very long video :/ it's mentioned in there.
Cables were just there in case the tower tipped over.
It was more a combination of temporary weights and freezing the ground.
