Dubai: 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.

According to a manager of Arabtec, the incident is under investigation.
