There are also loads of safety regulations on work sites. If someone is going into a confined space like a sewer, someone is monitoring their air, someone is in direct communication with that person, someone is watching over any lines or cables that have to go with the worker, and a whole group is directing traffic to make sure no one drives into the work crew.

Yes good points. He also covered how work has to be done in sequence so there is inevitably lots of waiting as dependencies are completed.

Precisely. You don't pay an electician to dig a hole. You don't let a machine operator do electrical work, and so on.
