There are no foremen, no building permits and the illegals do everything wrong that can be done wrong.So, after wasting about $700,000 on bad work a building inspector catches them and shuts the project down for about 9 months and makes them pull out every new window in every unit and replace them with the correct windows. 

Looks like 5 is shut down, probably being used as the fire break.
