Expansion of Zone A

Zurich Airport

Over 26 million passengers travelled through Zurich Airport in 2015. That’s almost one million more than in the previous year. So how does Switzerland’s biggest airport meet this challenge? Through constant struc-tural development. Gruner Kiwi AG as well as Gruner AG have been commissioned for the future devel-opment of Zone A.

Zone A is located in the heart of Passenger Terminal 1 and forms the entrance gate to Zurich Airport. Apart from the definition of the architectural language and the modular structure of the building stages, the ob-jective of the future development is the integral, functional and architectural integration with the neighbor-ing functional buildings and infrastructure elements.


Winning Team of the Tendering Process

In 2015, Zurich Airport AG (FZAG) sought a lead design team for this demanding task through a two-stage tendering process. As part of the winning team of steigerconcept AG, Gruner Kiwi AG is responsible for all building services planning, heating, ventilation, air-conditioning, sanitary installations, electrical and building automation as well as specialist coordination. The specialists from Gruner AG are being consulted for fire safety and soundproofing.

Energy-Use Concept and Planning Tasks

Based on Gruner Kiwi AG’s energy-use concept and FZAG’s existing potential, the newly constructed buildings will be connected to the existing power lines and current infrastructure. This presents the follow-ing planning challenges:

  • Installation/rerouting of service conduits
  • Ensuring a high level of supply security throughout all conversion phases
  • Flexibility in the use of the new buildings 
  • Operational optimization throughout all conversion phases 
  • Operational optimization with regard to low operating costs (Gruner Roschi AG supports this through simulations)
  • Digital planning tools – from a 3D model to BIM
  • Starting with the preliminary design, the entire planning will be consistently carried out using a 3D model that takes into account all building services. The latest programs and planning tools will be used for the layout, presentation and controlling. In the course of the project that will last until 2022, additional methods, such as Building Information Modeling (BIM), will be integrated into the planning process.

Stages of the Expansion

  • Subproject 1: Excavation of the perimeter, rerouting of several large service conduits, construction of a replacement building for tenants and users of the building that is to be demolished
  • Subproject 2: Construction of building A40 as a concrete base construction for the new baggage handling system (BHS)
  • Subproject 3: Conversions in the existing buildings A4 and D2, installation of the BHS technology

Upon completion in the year 2022, the base building for the BHS will form the cornerstone of the entire Zone A. The newly constructed roof surface of the building A40 will serve as potential for the expansion of Terminal A and new multistory buildings.
