In the wake of the collapse of the underground parking lot of an apartment in Geomdan New Town, Incheon, the Seoul Metropolitan Government is conducting an emergency inspection of large-scale public and private apartment construction sites in the city.

From tomorrow (10th) to the 9th of next month, the city decided to urgently inspect the safety of the apartment building construction site with special structures such as a non-removable plate structure.

The underground parking lot of the apartment in Geomdan New Town is designed as a non-removable plate structure in which the pillar directly supports the slab without beams.

The city has deployed the Seoul Metropolitan Government’s apartment housing quality inspection team to regarding 10 private apartment housing construction sites and regarding 2 construction sites of the Seoul Housing and Communities Corporation (SH Corporation), and utilized the Seoul City Construction Safety Advisory Group for regarding 5 general building construction sites with similar special structures. Check.

For each site, over three days, the first inspection of documents such as design drawings and the second on-site inspection are carried out, with an emphasis on the safety inspection of special structures.

In the field inspection, we plan to check whether the construction, supervision, inspection, etc. are properly carried out as designed.

In particular, we plan to use a rebar explorer to detect if the reinforcing bars, such as the shear reinforcement that caused the collapse, are not adequate, and to check the concrete strength with a Schmidt hammer measuring instrument.

The city is currently recording major types of public construction projects worth 10 billion won or more as videos, and plans to expand video record management to public and private construction sites worth less than 10 billion won from next year.

In March of this year, for public construction, the mandatory video record management was included in the special conditions of the construction contract.

In October of last year, the city proposed an amendment to the building law to the Ministry of Land, Infrastructure and Transport to expand the subject of photography and video recording to all buildings subject to building permits. We are going to promote it.

However, as it takes time to revise the law, we are pursuing a plan to take and store photos and videos for each major process as a building permit condition until the revision to prevent safety accidents and poor construction.

2nd Vice Mayor Yoo Chang-soo said, “We will record and manage all processes at the construction site as video to prevent poor construction and ensure safety and quality, and analyze the video footage to check whether there is any insolvency.” We will make Seoul a safe city through quality inspection.”
