1. The plaintiff's claim is dismissed.

2. The costs of lawsuit shall be borne by the Plaintiff.

. The Plaintiff and the persons involved in the construction work, including the Plaintiff, have expressed their opinions to install the instant blocking at the entrance of the tunnel in the arrival base as part of flood control measures.

A of the East A prepared a design drawing of the instant block, and reported it to an interested party without structural review. On June 28, 2013, He submitted the construction plan for the instant block without structural review to the Plaintiff, along with the design drawings received from the East Agymology, without structural review. The Plaintiff also approved the plan without structural and safety review or design change instruction for the block.

③ Unlike the initial design drawings, East Asia’s geological features made up of the steel plates 2,600m radius from diameters made up of defective melting, and 6m thickness of 2,600m radius from the original steel plates (which had been made up of 2,60m width, 2,600m length, and 6m thickness of 6m thick). Unlike the initial standard 90*90 on July 2, 2013, 201 the studs used as reinforced materials installed the studs at the bottom of the entrance of the tunnel at the end of the entrance of the entrance, at the end of the entrance, of the entrance, around July 2, 2013.

The plaintiff and Heung Construction did not conduct a safety diagnosis of the block of this case.

B. In full view of the materials, purpose, details, etc. of the blocking of this case prior to the determination, it can be sufficiently recognized that the blocking of this case was installed to prepare for the inundation of Han River water, not only for the purpose of preventing the natural inflow of the tunnels, such as industrial water generated within the destination base, but also for the purpose of preventing the natural inflow of the tunnels. Thus, this constitutes “a provisional facility” as provided for in Article 34-3 of the Work Manual for Participants in Responsible Supervision Field.

However, as seen earlier, the Plaintiff did not evaluate the safety of the block of this case, which is closely related to the safety of working workers in the tunnel according to the structure and performance of the structure and performance, and supplement this.
