Mexico City New International Airport is a new infrastructure project designed by Sir Normal Forter and launched in 2014. It is aiming to provide Mexico’s capital with a new state-of-the-art airport hub by 2020. The project is located to the East of Mexico City. The project will install an annual passenger capacity of 68 million passengers, more than the previous Benito Juarez Airport (41.7 million passengers annually, already the busiest airport of Latin America). The project features a X-shaped passenger terminal, 3 runways and a control tower.

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

Bartec coupler, often prefered in seismic areas such as Mexico, substitute on this project all reinforcement lapping of large ASTM #12 rebar (equivalent 38mm). On such large diameters, it is both faster and cheaper to connect bars with couplers rather than traditionnal overlapping.

Dextra has provided Mexico Airport with up to 10 sets of Bartec equipment (a total of 30 machines, with each set delivered in a container) for all rebar preparation operations. The impressive setup has been supported by our local After Sales team, training the machine operators and maintaining equipment to achieve optimal productivity.

Chennai International Airportis the main airport serving the southern city of Chennai in India. The airport, located south of the city, is the fourth busiest airport in India.

Dextra has been involved in the construction surrounding the airport renovation efforts, which took place between 2008 and 2012.

For Chennai Airport, Dextra delivered its popular Bartec rebar coupler solution, which is the main rebar coupler solution used on large projects in India.

The main contractor on this project was Herve Pomerleau International (HPI) – Consolidated Construction Consortium Limited.Contractor chose the Bartec solution to splice reinforcement in all columns and piers (vertical connections) as well as for the beams and foundation mats.

Thanks to its parallel thread technology and rebar prepared with various thread length, Bartec offers a very high level of performance while requiring only one coupler for standard applications (when one bar can be rotated inside coupler) and positional applications (when no bar can be rotated).

Mae Fah Luang Chiang Rai Airport, located in Chiang Rai, Thailand, is a vital transportation hub for the region. The airport serves as a gateway to the popular tourist destinations of Chiang Mai, Chiang Rai, and the Golden Triangle. In recent years, the airport has undergone a major renovation and expansion project to modernize its facilities and increase its capacity. As part of this project, Dextra supplied over 180 tons of dowel bars to be used as construction joints for the airport runway pavement.

The construction of a runway pavement requires a significant amount of planning and preparation. One of the essential components of a runway pavement is the construction joint, which connects the individual concrete slabs together. Construction joints are necessary to ensure that the pavement can withstand the heavy loads of aircraft and the extreme weather conditions. Without proper construction joints, the pavement can experience cracking, spalling, and other types of damage.

Dowel bars are a critical component of construction joints, as they provide load transfer between the individual concrete slabs. Dowel bars are typically made of steel and are placed in the pavement perpendicular to the construction joint. They allow for movement between the concrete slabs while providing support and load transfer.

For the Mae Fah Luang Chiang Rai Airport project, Dextra supplied over 35,000 dowel bars, totaling more than 180 tons of steel. The dowel bars were manufactured at Dextra’s facility in Thailand and were delivered to the construction site in stages to meet the project’s timeline.

The project has not only increased the airport’s capacity but also provided a safer and more reliable transportation hub for the region.
