Incheon International Airport Corporation

Terminal 2, which was the key facility of the phase 3 construction, was built in the northern area of the airport for separate operation. The feasibility of the facility’s location was evaluated through countless reviews and discussions as well as expert consultation from International Civil Aviation Organization (ICAO) and Federal Aviation Administration (FAA) in order to proceed with the project.

Terminal 2 has a total floor area of 387,000m² (38.7 ha), which is about 77% of that of Terminal 1, and has two underground and five above-ground floors. Improvements and reinforcement were made on the issues of the existing terminal to build a more convenient and pleasant high-tech terminal. The terminal constructed to the scale of 460m (0.3 mile) in length and 880m (0.6 mile) in width, using 323,000m² (32.3 ha) of concrete, 72,000 tons of steel frame, and 12,000 units of precast concrete.

The terminal was designed to form the shape of a phoenix upon completion of the phase 4 construction and embodies Incheon International Airport’s brand identity that combines Korea’s traditional culture and its modern creative culture through the concepts of green airport (airport that breathes with nature), eco airport (sustainable and eco-friendly airport), and smart airport (airport made safer and more convenient through advanced technology).

With completion of Terminal 2 which has an annual passenger capacity of 18 mil., Incheon International Airport took its first step as a mega-size airport that can accommodate 72 mil PAX annually.

Traffic Center 2 is a 184,000m² (18.4 ha)structure connected to Terminal 2 and contains the T2 bus platform and waiting room, AREX and KTX stations, and short-term parking lot. Especially, it monitors the customer demand for public transportation such as bus and subway to provide an environment where users can use taxis, buses, and subway more easily and wait comfortably inside the building.

The phase 3 construction built access roads from the airport entrance junction to Terminal 2 (total length 11.2km(7 mile)). The access roads and the connecting roads provide a transportation service that allows the users to reach each terminal within 15 minutes.

Four new interchanges were built on the access roads to make transportation system within the airport continuous and safer. The access roads are organically connected to the New Airport Highway, Incheon Bridge, and Yeongjong Bridge and to the external transportation system, completing an efficient transportation flow toward Terminal 2.

Through the phase 3 construction, 54 passenger aprons (37 attached aprons, 17 remote aprons) were constructed centered around Terminal 2. The construction, which included that of code F large-size aircraft stands and multi-purpose aircraft stands, was a consideration for the current and future aviation demands and trends. With the cutting-edge simulation and aviation lighting systems, multi aircraft ramping system (MARS), extendable boarding bridge, etc., Incheon International Airport has taken a step further in terms of its customer convenience and safety to a level fitting to its CAT-3b safety grade.

The phase 3 construction constructed the 53km (33 mile)-long BHS, extending the total length of the large-scale BHS of the airport to 141km (87.6 mile). The full-length 141km (87.6 mile) is equivalent to the distance from Seoul to Daejeon.

The Airport Railroad Express was connected to the fourth underground floor of Traffic Center 2 to guarantee passenger flow from the downtown area. In particular, the connecting railroad was constructed to enable transport between Terminal 1 and Terminal 2 in just five minutes to improve passenger convenience and help passengers who have mistakenly arrived at a wrong terminal to be able to quickly move to the correct one.

Before the phase 3 construction, there were the main control tower and the apron control tower 1, which had been built during the phase 1 and phase 2, respectively. However, upon completion of the Terminal 2 construction, the existing control towers alone could no longer handle the operation of the entire airport efficiently.

To get rid of blind spots in control and improve efficiency in airport operation, the phase 3 construction built the apron control tower 2 in the scale of 94.2m² (0.009ha)in height with one underground and 13 above-ground floors.

From the beginning, apron control tower 2 was designed to be of a similar height to the main control tower (100.4m(34.1 ft)) so that it can perform the roles of the main control tower in emergency situations.

Also, the structure reflects the results of the wind tunnel tests to secure safety in rescue from typhoons, etc. and has vibration control facilities installed in the top floors for the highest-level earthquake-proof design.
