Incheon International Airport Corporation, which manages Korea's main air terminal, said on Sunday that it will begin a 40-day clean-up project from Monday in preparation for the Seoul Nuclear Security Summit.
The grand gathering is slated to begin on March 26, with the heads of 50 countries attending. The airport, which ranks as the nation's largest building, consists of a main terminal measuring 504,000 sq. m, a concourse terminal (158,000 sq. m) and a traffic center (252,000 sq. m). Some 70,200 sheets of glass line its outer walls, and airport authorities plan to have all of them cleaned.
A total of 1,200 workers and 100 pieces of cleaning equipment will be mobilized for the Herculean mop-up.
