I passed by the site two days later. The only thing which had changed was a thin little red plastic fence around the biggest pit. The kind of thing that's intended to be a visual "don't enter", and has not real ability to keep anything out. Fair enough. But ...
Still no sign. Still nothing to keep kids out of the other pits.
A couple days later I drove by again (it's actually on my way to 95% of the city). Nothing new. However, they were digging a trench - oh, about 5-6 feet deep (1.75 m). The worker is standing in the trench watching the excavator's shovel come down right in front of his face.
What possesses people to stand in a trench/pit while it is being excavated, with the bucket coming down right in front of their face? In all seriousness, is this just a macho-thing? At my 'field experience' last Summer, I ran into this, too. Luckily, the IH who was a real employee pulled a "get out of there now". It was like watching someone deal with my 5 year old.
I haven't had a chance to ask MN-OSHA if they made a site visit?
