We have a client building a earthbag house in really remote spot in the Patagonia.
Couple of links to what i am talking about:

Yea, labor might be cheap in Chile, however it is not just the quality of the unskilled labor but the reliability of it. If you only get say 6 hours or less a day worth of work out of a laborer, you need to hire that many more labors to compensate. With the cultural management issues on top of it, just adding more people does not necessarily get things done faster. You see the problem?
For example, in the Patagonia no one will work even in doors on a construction project when it is raining. It rains about 9 months out of the year in some areas. Thus, the building season indoors and out is very short.
Another case in point comes from a special on Quellon unemployment the other night on TVN. Unemployment is running over 60%. They interviewed the city manager that said she had lots of government money to hire people part time now for improvement projects, but no one wanted to work because it did not pay as much as the Salmon industry use to. Yea, the Salmon industry is over, gone, never returning to Quellon; but, people now will not work at anything that does not pay as much.
Most of the big contracts for things like highways in certain parts of the country are all labor from Santiago. They won't even mess with trying to hire and manage the local workers on construction projects.
Now it is different in different parts of the country, but you need to factor in the labor issues anytime you hire for something like this in Chile. Thus, my inclination towards designs that with less labor. Simple stuff might work, but it would need to be tested carefully and have a backup plan if the workers become your biggest liability.
