Suvarnabhumi Airport is the main international airport of Thailand, operating both domestic and international flights and acting one of the main gateway to South East Asia for travelers in the region. The airport is located at the East of Bangkok, less than 15mn from Dextra main manufacturing facility.

Dextra has involved in the construction of the airport since the beginning in 2001, and has still contributed to the airport’s latest expansion projects.

Suvarnabhumi Airport’s second phase expansion is intended to increase the airport’s annual passenger handling capacity to 60 million passengers and provide an additional 28 gate assignments for international flights, bringing the service up to international standards and improving the convenience of passengers and airlines in a total area of 960,000 square meters.

More than 600,000 Bartec rebar couplers have been used extensively in all parts of the airports, including beams, columns, diaphragm walls and pile cages. This popular rebar splicing solution allow for a safe and reliable connection of rebars, for both vertical or horizontal applications.

The solutions were deliverd with rebar preparation equipment, along with our trained experts, to ensure that production requirements were met in a timely manner.

Moreover, RepairGrip and Unitec couplers were also used for the connection of 2 rebars with no thread or rebars that have splicing issue.

Heathrow Airport is the busiest international airport in the United Kingdom, located around 25km west of central London.

Dextra has been involved in the construction of Terminal 5 and associated structures.

For Heathrow Airport, Dextra delivered its most advanced rebar splicing solution: Griptec, which is distributed in the United Kingdom by local expert fabricators.

As a result of its high performance, inherent reliability, systematic proof loading of every connection in factory conditions and comprehensive certification, Griptec is specified by major consultants globally. In the United Kingdom Griptec holds all three of the CARES splicing product certificates. That is TA1-A, TA1-B and TA1-C.

For our distributors, servicing the rebar preparation, the Griptec solution is convenient and productive. It is supported by a smart machine, manned by a single operator, offers highly productive cycle times (around 45 sec per rebar prepared) and includes of a test that systematically proof loads each and every bar / sleeve connection.

On the contractor side, Griptec offered a simple, effective and reliable way to connect rebar in columns, diaphragm wall and slabs. One application at Heathrow was for the roof of the new underground station. Griptec connections were also used to provide temporary openings that allowed men and equipment to freely move through the rebar structure and be easily ‘closed’ using single lengths of rebar with Griptec connections to both ends.

Thanks to its parallel-thread technology, Griptec does not require any torque wrenching at a specific value and can be verified by simple visual inspection, a significant advantage to simplify the project schedule and keep operations as productive as possible.

Mumbai ChhatrapatiShivaji International Airport is the primary airport serving international airports to Mumbai. It is the second airport in India in term of passenger traffic.

Dextra has been involved in the construction of Terminal 2 and associated structures, which took place between 2009 and 2013.

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

Dextra operates in Mumbai its own threading yard and took in charge therebar preparation for this project.

On the construction site,
Bartec was used extensively for vertical connections (bar-to-bar vertical column connections), as well as horizontal applications (column-to-beam), typically on reinforcement ⌀32mm. Bartec offers a very high level of performance, guaranteeing “bar break” performance on the rebar used on Mumbai Airport.

For the contractor(Larsten& Toubro on this project),
Bartec offers a simple and cost effective way of connecting rebar.

Thanks to its parallel thread technology and rebar prepared with various thread length, it requires the very same coupler for standard applications (when one bar can be rotated inside coupler) and positional applications (when no bar can be rotated). A neat feature simplifying stock keeping and preventing product mismatch at site.

The King Abdulaziz International Airport (KAIA) is an international airport located in Jeddah, Saudi Arabia.

The airport, named after the founder of Saudi Arabia, King Abdulaziz Al Saud, is the country’s third largest and the busiest airport.

It has four operational passenger terminals: the North Terminal, South Terminal, the Hajj Terminal, and Terminal 1. The Hajj Terminal was created specifically for Muslim pilgrims who travel to Mecca every year for the Hajj.

Dextra supplied more than 300,000 Bartec couplers which were installed in bridge and exchange, tunnel, railway station, terminal, ATC tower, and car parking structures.

Suvarnabhumi Airport is the main international airport of Thailand, operating both domestic and international flights and acting one of the main gateway to South East Asia for travelers in the region. The airport is located at the East of Bangkok, less than 15mn from Dextra main manufacturing facility.

Dextra has been involved has been involved since the beginning of Suvarnabhumi construction back in 2001, and is still involved today in the airport’s latest expansion projects.

For Suvarnabhumi Airport, Dextra delivered over the years a vast range of technical solutions to support the various contractors on part of the project.

For foundation piles, diaphragm walls, columns and beams and other concrete structures, Bartec rebar couplers have been used extensively in all parts of the airports. The popular coupler solution allow to safely connect rebar together, as vertical or horizontal connections. In Thailand, Dextra also takes in charge the rebar preparation service, which is ensured from our own threading yard in Bangkok.

Terminal roofs and concourses have also been designed to use as cross-trusses Dextra Tension Bar Systems. The high performance large par systems are easy to install and adjust in length thanks to their fork ends and in-line connectors, and participate to the overall aesthetics of the terminal structure.

For plane remote parking area where plane fine tune communications with the control tower, Dextra supplied large diameter FRP dowel bars, connecting the tarmac concrete slabs.Dextra FRP bars provide similar tensile performance to steel bars but prevent some of the interferences inherent to metallic structures.

Kuwait International Airport is the country’s main airport located in the South of Kuwait City. The Hub can currently handle more than 9 million passengers per year, and is home to the famous Kuwait Airlines, Jazeera Airways, and Wataniya Airways.

A new state-of-the-art terminal

This newest infrastructure is part of the Airport’s expansion project, aiming to enhance its status as the State of Kuwait’s gateway. When complete, the Terminal II building will form a triangular mark, a symbol of Kuwait reflecting the country’s rich culture and civilization.
Scheduled for completion in 2020, this striking five-storey terminal building will be able to handle 25 million passengers a year, and will be connected to the first terminal via a tunnel.

From the foundations to the roofs

For this project, the lead Turkish contractor Limak Holding and its Kuwaiti agent Kharafi National have chosen Dextra’s Rolltec rebar coupler solution for rebar splicing in all the building’s concrete structures.

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.
