Mobile Crane Unknown Date

It's not a tower crane, but it's compelling. It's a mobile crane going over due to poor soils. It would appear that everything was intended to have been done right (matting layers are perpendicular), but the big picture is that you can't be so close to the edge on non-native soils without reinforcement of some sort. It would be best to use a soils engineer.

Operationally, guys noticed the soil giving way while the load was able to be landed back on the pilings. There really isn't a good reason why they didn't do that. Always take a moment to stop for safety. Even if there was no other injury, this is a 2.5 to 3 million dollar accident. How much would have it cost to set the load back down?
