Over here in my area, there is no specific amount, it mainly depends on how much was agreed between the constructor and the owner of the building or project. And this decision is usually made based on the work it self how hard or tedious it might be.
I'm actually work in the construction company some years ago and this was exactly the trip that they try to work on me but I had to refuse because I know they are going to end up cheating me without paying me very well.
