Dubai Aviation Engineering Projects (DAEP) has invited selected contractors to collect tender documents for the AED10bn ($2.7bn) substructure for Concourse 1 and the West Terminal building.

The tender closing date is 3 December.

The construction work is expected to include about 5 million cubic metres of concrete and 1 million tonnes of steel.

The enabling works for the terminal and concourse are ongoing. In June, DAEP awarded that contract to Tristar.

The enabling works for Concourse 1, the West Terminal building and car park require 20 million cubic metres of excavation and 6,000 piles.

For Concourse 1, the works involve open excavation up to 18.3 metres deep, piling and temporary dewatering and linking tunnels. Altogether, Concourse 1 covers an area of about 910,000 square metres and requires about 5,000 piles.
