This is an interesting point. There have been a number of construction-related scandals in the last thirty years of building public housing estates in Hongkong. Either the contractor used weak cement, insufficient rebar, or didn't drive piles deep enough. The fact that they were not caught until the building was completed is terrible. It says the QA by gov't was seriously flawed. (It has since improved a lot!)
I think the offset is to have a mixture of QA/checkers and gov't regulators who are onsite checking things. With huge civil engineering projects, sometimes the gov't will hire a competing civil engineering firm just to be onsite checking the work. That balance probably works.
