>>This happens in other countries too.

This is everyday life in India. A big budget is sanctioned to build a road. Road gets built, then a month or two later, some body forgets they didn't do the sanitary/sewage pipes well enough and manholes are now overflowing, they tear down the whole road and then just leave it as is.

The process restarts again in two years or so. Here is the rub- The guy who builds it at the first place knows all this so builds it as cheaply as they can get away with.

Its just how corruption works, and money flow from tax payers to politically well connected contractors(often the politicians themselves, as the contractors are just shell companies owned by contractors). Even if the company is black listed a new one can always be floated next time.

>>I suspect local governments are just inept at logistics.

No they are just corrupt. Its easy money. No audits, no accountability and no questions of any kind.
