Addendum, the day after. The job may be shut down, or they are taking a holiday. Usually they just rearrange the dirt. In my day, the Ministry of Labour had some hard-core geotech people. That's why you see all those heavy walls for trench work. But then then they relocated to some place horrible and lost the talent. The ghosts of these guys shudder at the concept of working in a permeable pit with the slope unravelling above.
Personally, I shudder to think that somebody important actually reads this crap. :) /\
