This is why here in Finland most large construction projects have in their contract with the main supplier/builder a limit on how many layers of sub contractors is allowed. This is 2 or 3 for most projects. This makes communication chains much shorter which usually leads into better end result. Also when things go wrong finding who is at fault is easier and it is more likely to be some big company that actually has money/proper insurance to be able to take care of it instead of some 2 or 3 person company that caused a multimillion fuckup and thus they would just go bankrupt instead of paying.
