Belagavi Airport's new upgraded terminal: A fine example of green airport construction built at Rs 43 crore in 30 months

01 Dec 2017 Long Read
The new upgraded terminal building at Sambra on the outskirts of Belagavi was commissioned on October 16 with the aim to facilitate passenger and cargo traffic in the region. With an area of 3,600 sq m, it has a handling capacity of 300 passengers (150 arrival and 150 departure) at peak hour.

Specs and designs
The new terminal building is spacious and showcases local art and culture. 'The structure has been constructed with a combination of RCC, glass and steel,' says Rajesh Kumar Maurya, Airport Director, Belagavi Airport, Airports Authority of India. 'The foundation has been designed for Seismic Zone-III. Further, the building is energy-efficient with a roof skylight and curtain-wall glazing.' An elevator has been provided along with parking for 160 cars, 11 reserved parking spots for VIPs, four coach or bus parking stands and parking for 36 taxis. The terminal has six check-in counters, 21 flight information display system, three elevating transfer vehicles, five door frame metal detectors and 15 hand-held metal detectors. For the safety and security of passengers, the terminal building has been equipped with a fire-fighting and fire alarm system, 80 CCTVs (72 in the internal building and eight outside), and baggage scanners.

Materials of choice
Considering the current trend in green airport construction, the new terminal building in Belagavi has been designed and constructed in an eco-friendly manner. 'The best quality materials and technology have been used in the construction of this new terminal building,' says Maurya, adding that about 620 metric tonne of structural steel and total steel reinforcement in RCC of 550 metric tonne have been used for the project. N Eshwarappa, Joint General Manager (Engg-Civil) and Project In-Charge, Belagavi Airport, Airports Authority of India, adds, 'For RCC, ready-mix concrete and batch mix concrete have been used with stone aggregate, river sand and 43-grade cement and steel reinforcement of grade FC 500 TMT bars.'

Fly-ash cement bricks have been used for the construction of the walls and 2,000 sq m of granite has been used for flooring in the check-in, arrival and security hold areas. Further, laminated glass on the city side and hermetically sealed double glass for sound insulation have been used on the air side. The building also features a 100-mm-thick metallic standing seam roofing system with sand witching rock wool for thermal insulation and a vapour barrier separately with plastic sheet for sound insulation provided with 28 per cent perforation in the bottom sheet backed with non-woven acoustic tissue paper. Apart from these, the terminal building has used ACP cladding; the false ceiling has been made with calcium silicate tiles and the ceiling with gypsum board.

Efficient mechanisms
To reduce electricity consumption, seven skylights have been provided in the roofing of the terminal building; the roofing system is a double insulated one. Further, to give a pleasant outer atmosphere and a vast landscaped look to an airport of international standard, curtain wall glazing with laminated glass has been used.

Structural glazing has been undertaken for all external walls and the top soil has been separated and used to develop gardens on the city and air sides. 'A sewage treatment plant (STP) of 50-kld capacity with moving bed bio reactor (MBBR), an effective technology, has been installed to recycle generated sewage from the new terminal building, integrated ATC and residential colony and other ancillary structures,' adds Eshwarappa. 'Treated water from the STP is used for gardening and horticulture. A water treatment plant has also been provided. All water and sanitary fixtures have automatic sensors, ensuring controlled water supply. The solid waste generated is segregated, and the treated waste from the STP is then used as manure.

What's more, rainwater harvesting has also been proposed, which will be executed through a separate tender. Besides, hydro-pneumatic pumps have been used for water supply. Apart from these, other green features of the new terminal building include low-heat-gain glazing, partial use of LED lighting, energy-efficient chillers and variable frequency drives for high-capacity motors. An HVAC plant of Blue Star of 3 x 100 TR screw chillers with air-cooled condensers has been installed.

Additional facilities
The terminal building has been constructed in about 30 months at Rs 43 crore. Apart from this, the total cost of infrastructure developed at Belagavi Airport is Rs 141 crore, as per the amount sanctioned by AAI, and the completion cost is over Rs 120 crore.

The infrastructure includes the extension of the runway by 470 m (now at 2,300 m), a new isolation bay, substation, new taxiway, night landing facility, a new 158 m + 131 m apron, ground safety equipment of 35 m + 131 m, a new ATC tower cum fire station cum technical block, and other allied structures. A new boundary wall with a total length of 11 km has also been constructed. Besides, the airport also has 13 watchtowers for proper control of the operational area; it has installed a new doppler very high frequency omni-directional range (DVOR), which ensures control over overflying flights and safer landing guidance to the pilot in command. Further, for better security of the operational area, a perimeter road of 7 km has been constructed. The upgraded airport also features the latest navigation and communication protocols with safety systems and processes.

Fully Equipped!
Ready-mix plant for RMC, transit mixer for transporting concrete, batch-mixing plant for smaller quantum of concrete, vibrators, generators, road rollers, trucks, dumpers, tractor, sensor paver and mechanical paver, cranes for lifting truss, and fork lights are among the equipment used in the construction of the new terminal building in Belagavi Airport.
