A building problem is today. It is in a city. A big part of the roof fell. This is from a high floor. The building is not ready.
The police come fast. They look for answers. No person is hurt. This is good.
Workers put strong stuff. Some think bad weather did it. We do not know why. The strong stuff was not good.
The police make it safe. They stop people. They want to know why. They check the work.
Big buildings can be bad. Parts must be strong. This is good for the roof. It stops bad things. People in charge watch work. Rules are good.
We will know more soon. We know if weather or work did it. The company helps the police. Work time can change. Safety is good.
