Bengaluru’s Kempegowda International Airport Terminal 2 (T2)

Project Description

Referred to as the Terminal in a Garden, T2 is a tribute to the Garden City of Bengaluru. BIAL said that the terminal is meant to be a “walk in the garden”, with passengers travelling through 10,000+ square metres of green walls, hanging gardens, and outdoor gardens built through indigenous technology. Located on the north-eastern side of Terminal-1, T2 spans 255,661 square meters of area and is equipped to handle 25 million passengers annually.

Design and Construction Team

Terminal 2 is to be developed in 2 phases to handle 25 million passengers per annum in Phase 1 and 45 million passengers per annum in Phase 2. It’s been designed by Skidmore, Owings & Merrill (SOM) architects and its civil construction contract was awarded to Larsen & Toubro with a value of approximately Rs. 3000 crore.

Project Requirement

The project was founded on four pillars: technological leadership, the idea of a terminal in a garden, environmental and ecological stewardship, and a celebration of Karnataka’s rich heritage and culture. A big draw of Terminal-2 will be its ‘hanging garden’.

The facility was spread across G+3 three floors. Though the height of the entire structure was 12.6 meters above the ground level, the pipe routing was complex with long horizontal and vertical lines. Bearing in mind not to spoil the elevation of the building, all the vertical shafts were mandated to be closed and could not protrude through the roof

Ashirvad Solution

The discussions started in Oct 2019 with L&T Constructions for Terminal T2. The Ashirvad design team closely coordinated with the L&T team to address the issues of balancing transient pressures in the drainage line and preventing the spread of foul smell from the toilets and kitchens. Ashirvad proposed and supplied Studor Maxi-vents (89) and Mini-vents (847) as part of the solution for this project.

Maxi and mini vents are one-way valves, opening to nullify any negative pressure transients generated in the system and remaining closed atmospherically in the absence of transients’ pressures eliminating the chance of any foul smells getting out from the stacks
