It's not hard to imagine that the practice is common. I know I'm cutting corners and don't know anything about construction, but if you make a little mental game out of it. If you have 20 men on site, dismantling crane probably shuts down most of the work on site, so you have to send most of the 20 men home during dismantling. You hire an outside contractor to dismantle the crane, so you probably want it to only take a day to cut costs on outsourcing and worker leave, you bring the dismantling crew in the morning to remove the pins and the lift the pieces off on the afternoon. There are thousands of cranes all over the world and there are probably dozens erected and dismantled daily. If we only have a disaster every couple of years, out of the hundreds of operations, that's when the practice get's exposed, it's like lottery but you win every time if you don't happen to hold the winning ticket. Truth of it is, many of us roll the dice with those odds.
