In the midst of this, it was argued that the building where the accident occurred was under extreme pressure to complete the construction quickly, so the site director changed frequently, and in the process, the position of the director was vacant for several months.



Another circumstance that poor construction may have taken place has been revealed, and this was covered by KBC reporter Ko Woo-ri.

This is a barrel containing solid fuel that raises the temperature when curing concrete in winter.



Hwajeong I'Park Tower Crane driver said in a phone call with reporters that he used only solid fuel without a hot air fan.



Another worker testified that relatively little solid fuel was used in Building 201, which collapsed.



He said that 80 solid fuel tanks were hung in the 1st complex and 40 in the 2nd to cure the first floor.



[Ahn Hyeong-jun / Former Dean of Konkuk University Architecture: In winter, you have to block the poured concrete with a plastic film and turn on a hot air fan to keep it at 10 to 20 degrees to properly cure it.]



He told me to work quickly in the 2nd complex where the collapse occurred .

It was also argued that the pressure was particularly severe, and that the subcontractor site managers changed frequently.



The director of the subcontractor of the 2nd complex, who is currently under investigation by the police, has only been working for about a month, and the position of the director has been vacant for several months.



[Destroyed apartment construction worker: (the two managers of the 1st and 2nd complexes) competed with each other and asked a lot to do it quickly.

There was a difference of about a month or two, but I heard that at the time, but I just did it and it became the same.]



A Hyundai Industrial Development official couldn't tell us about the amount of solid fuel used because it was an investigation under investigation, and he explained that the construction went as planned.



From the early demolition of Dongbari to the suspicion of poor maintenance, the situation is being revealed one after another that the apartment collapse accident was a collective human resource.
