COX’S BAZAR INTERNATIONAL AIRPORT TERMINAL BUILDING
Cox’s Bazar is the longest sea beach in the world. The concept of the airport terminal building is generated from or inspired by wave. The basic definition of is that, it transmits or transfers energy and information. An airport terminal is such a space where passenger transfers between ground transportation and aircraft.
The form is also inspired from wave. The directional change of water wave with respect to sunlight creates a soothing pattern inside the wave. This inspires the internal space of the terminal building to have such ambience and, it is brought by creating shade- shadow pattern inside the terminal due to space truss system with respect to sunlight.
LOW OF SPACE:
The internal space flow is made in such a way that the ambience of wave can be felt from all the floors and spaces by the combination of solids and voids. This also creates visual connection of one space to another.
The visual connectivity helps the passenger to feel the rush of the airport but also soothens his mind by shade shadow pattern and its change with the change in daytime.
Structural system comprises tree column connected to space truss system joined with ball joint
Metal frame holds 3 aluminium plates located on South, East and West. Only the North has glass plate to permit northern light.
Designing an Airport in Cox’s Bazar, worlds longest sea beach guided to do something in respect to the sea. Thus the concept of this International Airport conforms with the visualization of series of waves and engulfing into it to give an experience of journey through the long waves. It appears as a series of turbulent waves coming towards the front from a distance and in depth a person goes he may feel like merging into the waves.
Structure is mainly steel beams with concrete columns and purlins through the beams.
ETFE foils on the steel beam structure has been used to build the large span.
The building mass is North south oriented and the ridge valley gaps between two steel beams are used for welcoming light.They are shaded intensionally to diffuse the daylight.
Cox’s Bazaar is one of the most disaster prone area of Bangladesh. The site for the airport terminal building is very close to the coast and there is no barrier from the storm wind and cyclones that happens very frequently in that area. My first challenge was to make a building form that can sustain the heavy wind flow and air pressure that forms during cyclones and similar disasters. To reduce the air pressure and force of wind I minimized the building surface in the direction of wind. Further breaking the form the passageway of air was created.
To sustain the heavy upward air pressure during cyclone the structure was cross beamed which have maximized the stability of the entire form.
Organic green spaces throughout the building ensures the connection of passengers and nature and gives the opportunity to escape from the hectic activities of a terminal building.
My main objective was to improve PASSENGER EXPERIENCE and provide a space ingretated with the surounding lush greenaries. I zoned the areas according to their functional requirements cut SLITS of vegetation between them thus providing the passengers a space for RELIEF AFTER STRESSFUL LONG QUEUES. The bays connecting the separate masses will serve as a relaxation and socializing zone for passengers.360DEGREES runway view from the departure lounges is achieved through JUXTAPOSITIONING the height of the masses and creates a FORM BASED HIERARCHY AND UNIQUES VISTAS from different parts of the terminal.The service areas of the terminal receives ample sunlight thus providing a HEALTHY WORKING SPACE for the employees.
