A 17-story residential building in Incheon, South Korea collapsed during construction due to major structural errors and poor construction processes. The collapse was caused by a flat plate structure without border beams or walls for support, and missing reinforcing bars from the design and construction processes. The construction company, GS Engineering & Construction, has apologized and an investigation is ongoing. Residents are concerned about the safety of other buildings constructed by the company. The site was ordered to stop construction and 900 households were affected. There is currently no information on the cost of reconstruction or organization.
1. A large residential facility, a 17-story building, collapsed disastrously, with 16 floors collapsing during the concrete pouring process for the 39th floor.
2. The collapse affected the basement levels, with the roof of the parking lot collapsing, leading to bent rebar and falling cement.
3. Safety measures were taken to prevent further collapse, including supporting iron pillars and controlling the surrounding area.
4. The collapsed structure was constructed without border beams or walls to support the slab, with a flat plate structure similar to a previous collapsed building.
5. GS Construction, responsible for the construction, initially pushed back responsibility but later confirmed discrepancies between the construction and the design.
6. Critical structural elements, such as reinforcing bars, were missing in several columns, leading to concerns about construction integrity.
7. GS Engineering & Construction explained that they reviewed only parts of the design changes and attributed design responsibility to the design office.
8. The collapse led to a halt in construction, and plans for reconstruction or demolition were unclear, causing confusion among prospective residents.
9. GS Construction's decision to proceed with construction without consulting the ordering company added to the uncertainty surrounding the project.
