On October 8, 2021 (Friday), IFEZ signed an agreement for co-prosperity with a "meeting place" between the construction contractor of the third landing bridge and the construction company in Incheon. More than 40 professional construction companies in Incheon, materials, new technologies, and patent holders, including POSCO E&C Co., Ltd., a construction company in Section 2, and Hanwha E&C, a construction company in Section 1, participated, while each local company shared construction performance and construction methods. Through this event, IFEZ aims to reflect the design of technology proposals from local companies with excellent technology such as new technologies and patent construction methods, and to expand participation by registering professional construction companies as partners to achieve more than 76%.
