So i asked one of my colleague to translate the paper that I was shown when I went to complain. It is quite hilarious: it's a document issued by the traffic dept allowing them to close the road at night and that 'work should happen within the perimeter of the construction site'

However, this is from the traffic department only to close the road, it's no permission to work at night!!!

this is the construction site between W, beach tower and billal tower opposite of City Center
