Everything you wrote applies equally to western countries, and yet the results are different as we all well know. Whatever the reason is why trucks and other equipment stand around doing nothing, a reason clearly exists, and is clearly missing from your argument.

It may be that there is something going on in China that negates the exact reason that exists, and not in other countries, but you said nothing about that.

The fact is this construction site looks different than the way construction sites look usually. Your "trucks are expensive" argument explains nothing and provides no reason for this site to look different than others. Trucks are expensive everywhere, actually I think trucks are more expensive in the west than in China.
