My father is engineer, once he was renovating a shop in a intersection, he told the builders to use five tree trunks to hold the second floor while they demolished and rebuilt the first floor merchandise display. The builders decided to use only three, and pocket the money of the other two to themselves, and the building fell, thankfully my father had started working before signing the contract, so he could not be sued.
On Brazillian law the engineer is held responsible for everything that can go wrong, unless he proves it was not his fault...
This mean in Brazil there is a lack of experienced and honest engineers (the scumbag ones know how to not get shafted, the honest ones go to other countries, and the non-experienced ones... well, more meat for the grinder).
