Abu Dhabi International Airport
Abu Dhabi Airport is the main airport of Abu Dhabi, the capital of the United Arab Emirates, located approximately 15 km east of the city. It is the second busiest airport in the UAE, after Dubai International.
Dextra has been involved in the construction of the new Midfield Terminal (Terminal 3), which is set to enter service at the end of 2017. This expansion significantly boosts the airport’s capacity and provides new gates for large airliners, such as the A380.
Dextra played a key role in several aspects of the new terminal, including the foundation, concrete structures, roof, and façade.
Foundations & Concrete structures
For the foundation piles, Bartec couplers were used to reconnect prefabricated cages forming the foundation piles, as well as for other concrete applications. This solution was complemented by the use of Sonitec sonic logging tubes. The tubes, used for Crosshole Sonic Logging (CSL) integrity testing, are delivered in segments that can be easily reconnected by hand thanks to their bell mouth, saving time during installation. A total of 650,000 Bartec couplers and more than 110,000 meters of Sonitec tubes were installed at the Abu Dhabi Midfield Terminal.
Roofing and Façade
For the roofing structure, the Dextra engineering team provided two customized structural solutions.
For all applications requiring structural members to work in compression, Dextra supplied its Compression Strut solution. Compression Struts are easy to install thanks to their fork ends and conveniently allow for minor length adjustments at each fork. A total of 529 Compression Struts were installed for this project.
For trusses where the force is in tension, Dextra supplied its Tension Rod Systems. Similar to the Compression Struts, Tension Bars are easily installed thanks to fork ends, provide adjustment capability at the forks, and feature in-line turnbuckles. Dextra’s Stainless range was selected for this application, ensuring unmatched aesthetics with its mirror surface finish.
