The Ministry of Land, Infrastructure and Transport has narrowed 12 reinforcement proposals to two for columns at GTX-A Samseong Station, where large-scale rebar omissions weakened structural capacity. The remaining options are enlarging the columns with high-strength mortar and additional rebar, or combining that method with steel-plate reinforcement. MOLIT plans to select the preferred alternative by the end of the year after further reviews of train operations, seismic performance, three-dimensional analysis and construction drawings. Demolition and reconstruction remain under review. Once a plan is finalized, GTX-A trains will likely be able to pass through the station without stopping around the first half of 2027, although the timing depends partly on whether reinforcement can proceed alongside trial commercial operations. The Korea Concrete Institute said the station presents an unusual case that cannot be addressed directly through existing steel-plate precedents because the filling area and materials differ. A joint government task force is also examining design and construction, fire and electrical safety, and structural deficiencies across all four sections of the Yeongdong-daero mixed-use development project, including inadequate concrete cover and questions about bearing strength.
