Bangalore International Airport opened its doors in 2008. Six years later, it was categorised as the third busiest airport in India, after the Indira Gandhi International Airport, Delhi and the Chhatrapati Shivaji International Airport, Mumbai.
In 2011, the expansion of its central Terminal 1 building began, which was designed to increase the capacity of the airport from approximately 11.6 million passengers yearly to around 17 million. The renovation would also allow accommodation of the Airbus A380 ‘Superjumbo’, the double-decked aircraft.
With plans to cover an area over 150,000m2, the extended Terminal 1 building would need to include 30 self-service check-ins, 48 security systems and 90 check-in desks, as well as 5,300 seats, 15 baggage reclaim areas and 48 immigration counters.
Briefing of the idea took place with architects at HOK, along with the requirement that every aspect must be confined within a structure that creates a striking and intense presence, naturally blending with the current terminal.
Designs specified curved roofing in the shape of a rippling wave and inspired by a smile. The intense roof structure needed to provide complete protection for those arriving and exiting the terminal, as well as express a strong visual identity and physical presence for the entire airport.
HOK chose Elval Colour’s orofe to cover the 55,000m2 of its stylishly curved roofing. Specially reinforced aluminium Alloy 3004, designed for standing seam or corrugated roofing solutions, made up the lightweight coils, allowing flexibility and durability.
Orofe is built to create curvatures, making it the ideal choice for the wave-shaped design HOK had visualised. A PVDF liquid-based paint was applied to the coils after casting, which resulted in outstanding resilience and an optimal colour finish.
It took various teams at Elval Colour to create the final product. Coating, installation and rolling teams worked together to produce a roof that met the durability, performance and aesthetic criteria agreed with the project owner and its architects. As orofe is UV resistant, anticorrosive, incombustible and requires minimal cleaning or maintenance, the roof of Bangalore International Airport is constructed to last.
Upon completion of the project in 2012, it was Elval Colour that produced the finishing touch to the prominent airport; one that will continue to perform as a significant driver for the development of Bangalore, Karnataka, as well as the rest of Southern India.
