ZONE A – Baggage sorting system (GSA)

The baggage sorting system is a central infrastructure for passenger handling at Zurich Airport. The system is being comprehensively renewed and expanded as, among other things, key parts will soon reach the end of their useful life. 

Conzept Baggage sorting system

The GSA is being renewed and expanded for the following reasons: on the one hand, key parts of the system will soon reach the end of their useful life and will have to be replaced. Moreover, the existing systems for security checks on checked baggage will have to be replaced in future in line with new EU regulations. In addition, the existing GSA will reach the limit of its capacity in a few years’ time owing to current traffic trends. 

The entire project includes a new building to increase the capacity of the existing GSA by around one third, the replacement of many current parts of the extensive baggage sorting system and a larger early baggage storage facility to enable more flexible handling of the baggage sorting system. The new building will be constructed in a central location and will replace two buildings between Terminal 1 and the current core of the GSA. In addition, a large number of transport routes and systems throughout Zurich Airport will be renewed – from Check-in 3 in the south to Dock E in the north. 

Whereas the first construction steps began in early 2018, the first larger technical substitution will commence in autumn 2019 with the replacement of the current baggage transport system (“Bagtrax” system) in the 500-or-so long baggage tunnel that passes beneath the main airport complex. 

Flughafen Zürich AG is investing some CHF 500 million francs of its own funds in modernising and expanding the baggage sorting system. The construction project will take place in several stages. The last stage in Dock E is set to be completed in 2025.
