LafargeHolcim cement and concrete expanding Kolkata’s airport to handle new capacity

Between 2009 and 2011, Netaji Subhas Chandra Bose International Airport in Kolkata, India underwent a major modernization to upgrade infrastructure and build a new integrated arrivals terminal expanding passenger capacity. LafargeHolcim affiliate ACC delivered market-leading expertise and custom-built solutions to ensure a steady and on-time supply of cement and RMX.

 

Construction of the extension began as part of a government undertaking to expand Kolkata airport capacity following overcrowding in the early 2000s. The objective of the new integrated terminal was to serve both domestic and international passengers and handle significant increases in demand. The main contractor needed to be guaranteed the timely delivery of cement and concrete, something only LafargeHolcim could ensure among the various other subcontractors.

LafargHolcim: facilitator, contractor and concrete specialist from the design phase

Working as a “Facilitator-Contractor-Concrete specialist” on the project, LafargeHolcim got involved with the client at the design phase for the layout of the ready-mix concrete (RMX) plant, the design and trial mixes. We also helped facilitate concrete mix designs and operations control.

We were able to meet the special demands of the Airport Authority of India through complete transparency, traceability and well-established working procedures.

Overall, we provided:

  • 90,000 tons of cement
  • 250,000 m3 of RMX
  • Used two on-site RMX plant capacity of 80 & 30 m3/hr

Our expertise coupled with our technology and capability to provide consistently superior quality concrete, proved critical to the project’s completion. We delivered onsite solutions and ensured continuous batching plant operations, while also consulting on plant layout to increase output and ensure safe operations.

The expanded Kolkata airport is now spread out over 233,000 m2 and is able to handle 25 million passengers annually, compared to the previous capacity of five million. Travelers now transit through a spacious, bright and modern terminal on their way to their next destination, thanks in part to LafargeHolcim.
