Behind the Build: Who Actually Built Incheon International Airport?
Incheon International Airport is one brand on the marquee — Incheon International Airport Corporation — but the project runs on named specialists (LAPP, Otis, POSCO ICT, Siemens and more). Every supplier link below is verified with source_url + quote.
TL;DR
Bottom line: Incheon International Airport looks like one marquee name (Incheon International Airport Corporation), but at least 7 verified system slots are served by named B2B suppliers — elevators, structure, facade, MEP, and more — each backed by a published source. See the slot→supplier table and source quotes below.

You know Incheon International Airport. You might know the operator — Incheon International Airport Corporation. But Incheon International Airport is not one company’s product; it is an assembled system. Each system slot below is a different brand’s specialty — every line backed by a published source.
