Due to the massive physical scale of the masterplan, others would come to claim that Dubai World Central would be the most ambitious airport project ever envisioned. The latest estimates by the government of Dubai peg the price tag at US$82 billion. This "aerotropolis" would be a whopping US$62 billion more expensive than the next most expensive airport project Hong Kong-Chek Lap Kok International Airport Core Project—which cost the Hong Kong government around US$20 billion (in 1997 dollars). This would also make it the most expensive single project in the world, ever (with the possible exceptions of the Dubai Waterfront, The Palm Deira, and New Songdo Intelligent City).
