Plumb Bobs are basic tool

Plumb Bobs have always been a necessary tool to make sure things are installed perfectly vertical. Can you imagine building a say 40 story tall building and keeping it perfectly vertical from bottom to top? say you were off 1/16" from one story to the next. In 40 stories that would mean 40X 1/16"= 2.5".
By hanging a plumb bob in a bucket of oil up the elevator shaft,on a piano wire and using it to measure off of on every story, you will be exactly on point as you build upward.
This might be the type of “Bob” that can be used for that.
