What went wrong

  • Fire-protection automation: The single biggest cause of the 2012 cancellation. The bespoke smoke-extraction system, designed to push smoke down through the floor rather than up through the roof, was unprecedented in commercial aviation and never passed certification as designed.
  • Public-sector general contractor: The airport company chose to act as its own general contractor rather than appoint a single industrial GC. Coordination across hundreds of subcontractors became uncontrollable.
  • Mid-build scope changes: Capacity targets were revised upward repeatedly after construction had begun, requiring rebuilds of finished sections.
  • Political board governance: The supervisory board comprised politicians without industrial-construction expertise.
