Dubai’s Department of Civil Aviation (DCA) has selected the local Alec for the contract to build concourse 4 at Dubai International airport.

According sources close the project, DCA is preparing to issue a letter of award to Alec for the works.

The contractor will manage sub contractors appointed by DCA to complete a series of separate packages on the concourse that will be connected to the airport’s existing terminal 1 building and will serve international airlines.

The construction work on the project includes: enabling works; building the substructure and an automated people-mover station; completing the super structure, architectural finishes and mechanical, electrical and plumbing works; and installing lifts, escalators, travelators, and passenger loading bridges.

The concourse will be located to the west of the existing Concourse 1 near to the cargo terminal and will be connected to Terminal 1 by an elevated bus road. The site area covers about 225,000 square metres and the total built-up area is expected to be about 135,000 sq m.

Lebanon’s Dar al-Handasah prepared the initial design and tender documents for the contract.

Alec is already working at Dubai International airport. It is currently building Concourse 3, which is due to open at the end of 2012. It secured the contract, which involves building 20 contact gates, including 18 gates specifically designed for A380 aircraft.

Another expansion is also ongoing on the other side of the airport’s runways. In early January, the local Arabtec Construction has won the AED561m ($153m) contract to expand and refurbish Terminal 2 building that serves budget airlines.

The project involves doubling the size of the terminal from 30,000 sq m to about 60,000 sq m. For the selected contractor, this will involve about 30,000 sq m of new build and 25,000 sq m of refurbishment. The contract duration is 25 months.
