I lived in a house near downtown Houston built in 1963 and that house was
full of asbestos and it came very close in killing me. People whom buy
houses in this area have to contract with an asbestos company in which
the workers are dressed in special suits that resemble spacesuits to remove
the asbestos.
The house would be down to the bricks and mortars and the wooden frame.
The World Trade Center in NYC would be cheaper to replace. However, the
asbestos would have to be removed by hand and would be an very
expensive to remove, and a very expensive demo.
The residue of the asbestos of 9-11-01 will be in the area of the destroyed
World Trade Centers will never go away. And will cause people sickness in
years to come.
