WALL COLLAPSE

Well, I'm not really surprised by this. Things like this eventually happen if everything is done in such a rush. You didn't hear much about this in the local news, such incidents are rather kept quiet. The crane was 30 meters tall and collapsed when the water filled the site, only the top bit reaches out of the water.

Lucky escape for 100 workers
Nearly 100 workers at the site of the 'tallest building with a twist' had a lucky escape yesterday as a wall holding back the Dubai Marina waters breached and flooded the foundation site.
Excavation work on the 80-floor Infinity Tower was nearing completion when there was a sharp and loud sound, said a worker. "We then saw sand pouring down the sides," he said. The workers were ordered to evacuate immediately, said the foreman.
The Dh700 million 80-floor tower is to have a 90 degrees twist.
