Ok, that doesn't count the preparation and constructions of different parts but still, that's impressive!
Another collection of masterpieces of stupidity during constructions.
In Saint Petersburg on Friday 11th, several concrete blocks collapsed from a building under reconstruction on the roadway, crushing parked cars. At least five cars were damaged. One man was in his car when the blocks fell down. One of them fell on his car trapping the man inside and causing him injuries.
The victim was taken to the hospital, his condition is serious.
FYI: the weight of one block is about two tons.
