Australian construction company BESIX Watpac has secured the contract for the next stage of Adelaide Airport’s infrastructure development, referred to as Project Flight.
The project continues a partnership of 15 years, during which the company has completed six projects within the airport precinct.
BESIX Watpac CEO Mark Baker said: “We deliver certainty for our partners through our collaborative approach, specialist expertise, and productivity-enhancing approach to building that includes the strategic use of digital construction methods. This has led to repeat engagements across the sector and recognition through numerous industry awards.”
The planned works are intended to support Adelaide Airport’s long-term aviation strategy and respond to increasing passenger numbers.
The expansion will include a series of targeted upgrades such as a larger check-in hall featuring advanced technology, a 10,000m² extension to the Northern Terminal, and a 5,500m² expansion of the Southern Terminal.
The upgraded check-in area will include new kiosks and additional bag-drop facilities, enhancing the efficiency and experience for travellers, BESIX Watpac said in a press release.

These included a major terminal expansion that was completed in 2021.
Current work also includes upgrades to passenger screening and baggage handling systems.

Construction of the facility is scheduled to start shortly and will be executed in phases over the coming decades.
