Cost & Financial Arrangements

Estimated Cost for Building the 3RS

The scale of the 3RS project is almost equivalent to building a new airport next to the existing one.

The estimated construction cost is HK$141.5 billion at money-of-the-day prices, of which approximately 40% will be used for land formation. In addition, up to HK$22 billion will be invested for environmental protection measures, including advanced reclamation methods (e.g. deep cement mixing) and horizontal directional drilling.

Joint Contribution and User-pay Principle

The financial arrangements for the 3RS will be based on the “joint contribution and user-pay” principle. Funding will be provided through the following three channels:

  1. Bank loans and issue bonds
  2. Retaining HKIA’s operational surplus for project investments
  3. Charging an airport construction fee to departing passengers
