Phase two
Phase two of the airport construction began in February 2002 and completed in June 2008 (the project brought forward because of the Beijing Olympics). Airport capacity increased to 410,000 flights a year serving 44 million passengers a year and processing cargo volumes of 4.5 million tons a year.
Phase two entailed preparing 8.25km² of land on the west side of the airport for a 4km third runway, 1.2km² mooring facilities and a 158,400m² concourse, which are connected to the main passenger building via two parallel 870m-long underground passageways.
In addition, there numerous equipment upgrades were carried out. They included the new ASDE-X with multi radar tracking (MRI) function, and an automatic dependent surveillance-broadcast (ADS-B) system with a runway incursion monitoring and conflict alert system (RIMCAS) function.
The installation of four additional sets of ASDE-X antennas is currently being planned to reduce blind spots brought by heavy rainfall and in preparation for the new runway.
