Belgium's Dredging International, Ballast Ham Dredging, Jan de Nuland Van Oord, all of the Netherlands, and the US' Great Lakes Dredge & Dockare among those shortlisted to bid for the package. The scope covers the dredging of about 60 million cubic metres of material to create a stable platform for the new airport; construction of a 14-kilometre-long armoured revetment to protect the platform; and construction of a short approach channel, turning basin and offloading quay for the aggregates and construction materials.

The new airport is to be built on a 21 million-square-metre plot of land, of which about 11 million square metres will be reclaimed. About 18 construction packages are expected to be tendered on the first phase of the airport development, with bidding on the other packages set to start in the second half of 2005. The airport's first-phase development, due to be completed in 2008, will have capacity of 12 million passengers a year.
