Brussels Airport

Since the early 1990s, BESIX has played a key role in the long-term development of Brussels Airport. Over the years, the Group has delivered a wide range of projects, including passenger terminals, railway infrastructure and advanced logistics facilities. This long-standing partnership has supported the airport’s continuous evolution, enabling it to accommodate growing passenger traffic and meet the demands of a major international hub while remaining fully operational.

At Brussels Airport, BESIX has successfully delivered a series of complex projects across multiple disciplines, often within a live airport environment. These include the construction of a seven-level terminal, the two gate piers serving Schengen and non-Schengen traffic, a 300 m railway tunnel under the road infrastructure, a 400 m tunnel beneath the runways for the high-speed rail connection.

At the cargo side of the airport, BESIX developed a logistics pharma hub featuring 50,000 m² of warehouse space, 10,500 m² of offices and 88 loading bays. Each project has required meticulous coordination, phased execution and the ability to work within highly constrained operational environments.

In the early 1990's construction of:

• New 7-storey terminal building

• 3-storey "Pier B" and a series of access bridges and roads

• Complete rail station 20 metres below the ground

• 300-metre rail tunnel under the road infrastructure

• 400-metre tunnel beneath the runways, between the passenger terminal and the future Pier A

At the start of the 2000's:

• New "Pier A" with three floors and 31 boarding gates including a technical corridor, a luggage corridor and a public corridor with three passenger conveyor belts and 10 lifts

• New 5-storey infrastructure

More recently:

• Logistics pharma hub comprising 50,000 m² of warehouses

• Contribution to the new tram line linking Brussels city centre and the airport
