While the Incheon Metropolitan City and the Ministry of Land, Infrastructure and Transport are working on responsibility and measures to prevent a recurrence, such as inspecting the site of a collapse accident at a new apartment building in Geomdan New Town, Seo-gu, Incheon, the possibility was raised that defective concrete has been used.

Late on the 29th of last month, 970㎡ including the slab on the 2nd basement floor collapsed due to the collapse and impact of the 1st floor slab of the new flat underground car park built by GS Construction and operated by LH in Geomdan Tref Newydd, Seo-gu, Incheon.

All of them happened in a situation where the construction work started in May the year before last on a scale of 964 households and 67% have progressed at this time.

This construction method is the Construction Management Responsible (CMR) method, which is essentially overseen by the owner. From the detailed design stage, a contractor is selected and involved early, and the construction work is carried out within the contracted construction cost under the responsibility of the contractor.

Originally, this apartment was supposed to be completed in October this year and moved in in December, but the move-in is expected to be delayed as Minister of Lands, Infrastructure and Transport Won Hee- between issuing an order to stop the construction work. in order to cope with and investigate the fall.

According to GS E&C, the underground car park that has collapsed is that the existing shear reinforcement bars connecting the top and bottom reinforcement bars in the slab have been omitted in 30 places out of 700 places on the entire roof floor , which is different from the design.

GS E&C issued an official apology on the 9th and announced its position that it would cooperate thoroughly and transparently with the future investigation process.

It was declared a self-investigation as simple negligence because the cost reduction was not meaningful because it was about 10 million won at most, and the construction period was not shortened.

Furthermore, as a result of the Ministry of Land, Infrastructure and Transport’s inspection of the quality control of ready-mixed concrete companies, three concrete suppliers are known to have been deemed unsuitable. In detail, it was said that the surface yield control of the fine aggregate was not sufficient and that the mixing time was different from the result of the performance test.

Around the construction site, there is a possibility that defective concrete was used at the accident site, and the argument that a close eye should be kept on the investigation process is becoming more persuasive.

Mr said. Kim (55, Guwol-dong), prospective tenant, “The fact that an accident with a backward nationality should never happen on a site ordered by a government construction company and construction by a leading domestic construction company ignores. Incheon and cheat the citizens of Incheon. act,” he complained.

Regarding safety accidents at construction sites, Mayor Yu Jeong-bok emphasized that construction companies should do their best in safe construction with a sense of great responsibility.
