how many to pour a sidewalk

[mark]

I was wrong on my original post, they didn't pour the sidewalk just the curb.

Since then, they have left, another crew showed up and graded/packed the street, took all their equipment away. Another crew, different equipment, laid out the gravel and after grading gone. Yesterday noticed sprayed oil and see today the paving crew is starting to show up today.

Not sure when the sidewalk will be in.
