The Mexico City New International Airport is a major infrastructure project designed by Sir Norman Foster and launched in 2014. It aims to provide Mexico’s capital with a state-of-the-art airport hub by 2020. The project is located to the east of Mexico City and is set to accommodate an annual passenger capacity of 68 million, surpassing the previous Benito Juarez Airport, which currently handles 41.7 million passengers annually and is the busiest airport in Latin America. The project features an X-shaped passenger terminal, three runways, and a control tower.

For this, the largest infrastructure project in Latin America, Dextra has been involved in supplying its ข้อต่อเหล็กเส้น Bartec for the foundations of the terminal building (contractor ICA), the transport building (contractor Sacyr), and the control tower (contractor Aldesa).

Bartec couplers, often preferred in seismic areas like Mexico, replace the traditional lapping of large ASTM #12 rebar (equivalent to 38mm) on this project. For such large diameters, it is both faster and more cost-effective to connect bars with couplers rather than using traditional overlapping methods.
