Vadodara Airport in Gujarat handled about 9.32 lakh passengers, with a growth rate of about 30 per cent over the previous year. Such steady growth necessitated the construction of a new terminal building to provide more room to manoeuvre passenger inflow at the airport.

Spread over 18,120 sq m, the airport comprises the main new terminal building, a food court and service block. All services such as water supply systems, power supply, standby power supply system and HVAC are housed in separate service blocks connected by an underground service trench. The main terminal building structure has been designed to provide maximum obstruction-free movement area to end-users. Further, the building has been designed on a pile foundation and the super structure with elegant tubular trusses over the columns and beams.

Smart materials
The new terminal building has been provided with energy-efficient glass, which allows light to enter the building and restricts heat. The project has also been provided with a rainwater harvesting system and sewerage treatment plant (STP) with zero discharge.

There are 25 recharge wells provided to use rainwater for supplementing the groundwater recharge. The STP has been provided to treat soil waste generated with zero discharge. It is designed with soil bio technology with a patented product of Prof Dr Shankar of IIT, Mumbai.

Thus, the groundwater recharge improves the water table with potable water and reduces the load on drains. At the same time, STP with soil bio technology ensures zero waste and the green plants over the STP help improve the environment.

Additionally, the new terminal, a unique steel structure, is designed with an advanced building management system; one feature is that the area’s air-conditioning system automatically switches off when there is no movement. The public toilets also have an auto-switch-off system for lights in case of no movement.

The airport has used fly-ash bricks in construction. It has also made use of sugarcane bagasse as a decorative material in the reserved lounge and CIP lounge areas. This also reduces the load on demand of fresh decorative products.

Surveillance
With advanced security systems, the terminal has made use of travel safety and security equipment such as hi-tech security systems and a super-sensitive fire safety alarm. The VESDA fire alarm system for early smoke detection has been used. The new terminal building has been designed considering all passenger conveniences such as food and beverage, toilets, childcare room, smoking room, CIP lounge, separate food court outside the terminal building, etc.
