I think they forgot to add concrete, or more likely due to corruption it was sold off and replaced with sand
Lucky the Mall was closed when the Abreea Mall Road Collapsed. Some sites say it is a pathway, but it is obviously the road around the building to the parking areas. The road collapse looks like it is into the car parking area.
I would not like to be living in that building, the tallest in Davao, and new. How strong are the foundations?
