Water-system modules dispatched in October 2026; V1 schedule plans Davis over-ice resupply for 4-13 November

Project sources

The AIR Alliance's first Davis renewal season delivers seawater-intake and reverse-osmosis facilities. October dispatch and the V1 receiving schedule define the logistics phase ahead of the new water-system installation.

Project anatomy

Contract scope and delivery roles

Client / authority
Australian Antarctic Division, Department of Climate Change, Energy, the Environment and Water
Delivery parties
AIR Alliance: Australian Antarctic Division, Bouygues Construction Australia, Stantec and Mott MacDonald
Contract route
AAD established the AIR Alliance in May 2025 after a multi-stage open tender. The alliance delivers the Davis Critical Infrastructure Works under a program-alliance model.
Execution window
Water-production works begin in the 2026-27 season. The V1 schedule lists a 4-13 November 2026 Davis call. The new utility building is programmed from late 2027 and the broader works are due in 2032.
Works package
First-season seawater intake, containerised pump house, reverse-osmosis plant and associated site services. The broader Davis renewal includes a new main powerhouse and workshops, asbestos removal, reticulation and return of old buildings to Australia.
Marine interfaces
Nuyina's planned position about one kilometre from station buildings places cargo handling and the over-ice route between the ocean voyage and the water-system workfront. Intake installation then connects the coastal source to treatment and station distribution.
Commercial evidence boundary
The alliance combines design and construction with Antarctic logistics. Module delivery, foundation availability, temporary power and permanent reticulation each control a different part of the installation sequence. Detailed load allocations and component-specific service-release dates belong to the voyage and construction plans.

Evidence gap

What remains unverified

Outstanding evidence

  • Actual V1 arrival, cargo receipt and released over-ice route
  • Module loads, vehicle configuration and installation-plant sequence
  • Intake, foundations, temporary supplies and permanent service connections
