Title: Former Maintenance Worker: The foundation of a collapsed apartment in Miami has been infiltrated by sea water 20 years ago

According to the Washington Post, William Espinosa, a former maintenance employee who worked on the building from 1995 to 2000, said that at that time, the staff had to pump the excess water out of the garage. . He pointed out that the seawater would seep downwards: “I’m talking about a foot (about 30.48 cm), sometimes two feet of seawater at the bottom of the parking lot.” But when Espinosa raised this issue with the apartment management, They only said that this problem has occurred for many years and did not take action.

John Turis, a resident of the Champlain Tannan Apartment, also declared, “The underground garage is always leaking, and it used to leak in my car.” John happened to be away from home when the building collapsed, which allowed him to escape. .

Although the cause of the collapse of the Champlain Tannan apartment is still under investigation, many engineering experts mentioned that the continuous accumulation of water in the basement may be one of the factors that led to the collapse of the building. “Cracks exposed the steel structure used for reinforcement, and the steel bar rusted under the penetration of seawater, which made it lose its original support function.” Henry Koffman, professor of civil engineering at the University of Southern California (Henry Koffman) ) Means.
