M.I.T (Maafushi International Airport Terminal)

Redevelop & Reclaim

To implement a new passenger terminal it is essential to create and implement a strategy of island reclamation. By developing a series of new atolls that would create a boundary around existing atolls and lagoon the existing conditions, the new terminal will exist on the new atolls to help increase mass tourism.

Maafushi island, the lowest lying island in the Maldives. Makes it the idea spot for the new terminal development. Already home to many residents and tourist attractions, there already exists a sufficient infrastructure that would aid in the redevelopment and reclamation of the island and those around it.

The shift from climate threat to mass tourism as a strategy for the Maldives takes a new look on the country’s plan for redevelopment. With the integration of a new terminal, this will not only aid in the increase in mass tourism but will become the catalyst for climate change in the country.

Redeveloping the narrative “The new government plans to relocate residents to larger atolls – leaving small islands ripe for development.” (Vidal, 2017). The new passenger terminal will increase people flows and business to the country. As population and tourism booms, the scope to expand the terminal over time allows relatively easy expansion, with the option to build at the same time as the current terminal is in use. It is key to understand that the linear arrangement of the terminal allows clear passenger flows and clashes in the main civic space. The terminal brings a new building typology to the Maldives, one that will allow the culture, economy and heritage of the Maldives to survive much longer than previously predicted, whilst enhancing the country, environmentally and ecologically.

ÂŁ for the Maldives

The terminal is designed to be zero carbon or even carbon neutral at specific times of the year. The proposal utilises abundant resources in the Maldives, in both construction and in-use. All services are off the national grid, only over supply of energy will be fed back into the main grid. Increased biodiversity and agriculture will allow for bigger revenues and coral reef regeneration creating a self sufficient building to allow reduced dependency on the main grid.

To adapt to the immediate threat of flooding that is impending due to sea level rise, the objective of this part of the proposal is to develop a sustainable urban strategy. Using the redevelopment of the coral reefs, the proposal is to produce specified construction materials and prefabricated frames for the foundation structures. As the process is cost effective and building materials would not have to be shipped to site. The process is carbon neutral if an electrical current if generated from renewable energy sources to grow the Biorock.

5 Limestone

6 Marine Life

Mineral crystals naturally found in sea water, mainly calcium carbonate and magnesium hydroxide, to grow on the structure.

Within days, the structure takes on a Limestone coat which has a grey hue as it becomes encrusted with precipitated minerals adding rigidity and strength (Construction).

The shade offered by the structures in the water attract a variety of marine life. Fish, crabs, octopus, lobster and sea urchins often colonise in these spaces.

7 Apply Coral Parts Once the reef structure is in place and minerals begin to coat the surface, drivers transplant coral fragments, attaching them to the arks frame. These coral pieces begin to bound to the accredited mineral substrate.

2100 The terminal has become much more hybridised as a system, with the opportunities for expansion and cross programming where needed. The need for a terminal that could be expanded over time was an essential driver. All elements of the terminal are separated, with no fixed elements that can not be removed.

The terminal also caters for redundancies, in the case the airport were to decrease in passengers, the elements could be moved/ re-used and the roof system could be utilised for another purpose.

Aerotropolis, imagined by John Kasarda in 2012, is an exaggerated example of the hybrid model in which the airport a strong feature in the urban physiology of a place, supporting business, tourism and culture.

Complete unit lifted into place Through years of growth, the Biorock © cages are ready to be lifted into place. The idea is that this will start the diversification and improvements to the coral reef and marine life around the island. As the cages are lifted into place, more of the cages are placed down to grow, this allows for continuous construction of each new terminal and new proposed atoll.

Continuous Anatomy

Level 2

Level 1

Level 0 By using a continuous style of development and construction, coupled with the linear routes through the terminal, it becomes an easily navigable space for passengers. The options to dwell, look through and explore the space, provides users with a unique experience, of light, colour and texture, through visual and feeling. The terminal space intends to provide big open spaces with lots of natural lighting. With no closed faรงade, the naturally ventilated terminal gives the authentic outside condition throughout the terminal space.

Continuous Anatomy The terminal is designed to be a smooth transition from one side to another, for either, departing or arriving passengers.

The mixed use of programme allows the spaces to become much more than processing space, they hybrid programme is designed so people can dwell, sit and observe the workings of the airport terminal. It is a way for interactions and clashes of people to happen, mixing from space to space, both vertically and horizontally.

The 2 civic spaces at the front of the terminal have steamed from the vibrant and disorganised nature of the market culture in the Maldives. The recreational space can be used as events spaces and is proposed to mix passengers and culture in one space. Whether a passenger is arriving or departing it becomes an instant reflection of Maldivian life. The pale blue colour injects life into the building and is representative of security and safety in many cultures around the globe, the colour falling from blue to almost silver as a passenger would move from one end of the terminal to another, represents the change from sea to land.

The design of the façade stems from the analysis of the climate conditions. Comfort level is typically between 15°c and 25°c, in a climate where the external average air temperature of 24°c, there is no inherent need to have a sealed façade system. The undulating element is designed to become much more dense in areas of privacy throughout the building, such as security and immigration.

Each element will be fixed to the timber gridshell roof system, and can be easily detached in the event that the terminal must be expanded in the future.

Secure & Depart

Security Checkpoint 17m x 6m

Security is dealt with in a way that is traditional in its approach.

The standard procedure is familiar with all passengers. The difference here is that passengers have a space to dwell before their flight, preventing long ques. Passengers can move through here as soon as check in, or dwell in the market/ civic space before moving through to security. Dealing with security at this points means that passengers working their way through the departure lounges have been regarded safe to enter into the air side space.

The split floor plates are designed to allow floods of natural light into the floors below. The aim of the design is to allow passengers to view down through the voids to witness the workings and anatomy of the terminal and also illuminate the space for navigation and provide light to perform tasks such as checking tickets and security. It is essential to provide such a compact terminal design with lots of natural daylight, making use of the unique amounts of clear daylight that floods the site.

Strengthened Security- Focusing resources based on risk, increase unpredictability, make use of existing technologies, introduce new systems as they become available.

Increased Operational Efficiency- Increase throughput, optimize asset utilization, reduce cost per passenger, and maximize space and staff resources.

Improved Passenger Experience- Reduce queues and waiting times and use technology for less intrusive and time consuming security screening.

The airport of the future requires many more advanced techniques, it was a priority to create a space that was flexible enough to adapt to the changes in technology into the future.

The openness of the terminal allows ease of removal or adaptation. A priority in the design process.

Arriving & Collecting Disembark Aircraft 1: Enter baggage area and collect luggage

2. Enter immigration & Passport check

3. Pass through arrivals security & bag check

4. Merge into the main civic space

5. Dwell in the main terminal/ Exit the terminal.

6. Board a boat/ sea plane to destination/ walk to destination on island via island baggage handlers and guides The arrivals hall will be the first space a passenger sees, the transition in colour as they make their way out of the terminal is representative of the gradual change from sea to land.

The exposed timber structure will act as a guide, pointing passengers through the space. The space is designed to get people through as quick as possible, baggage is unloaded and within minutes it is with the passengers due to the short distance from plane to baggage belts.

Increasing biodiversity on the site was a key driver to the design principles of the terminal. With tourist boom it was seen as an opportunity to integrate diving and fishing into the proposal.

The use of BiorockŠ to regenerate the coral reefs is intended to create a spectacle to increase research and tourism, combined with the need to service the terminal with food, saw opportunities to increase the Maldives export of fresh tuna thus increasing revenue for the country to aid constant development into the future.

Structural Steel Support The kit of parts system has been optimised to utilise the fewest parts for the construction of the terminal. The system makes use of every part inside the box and including the container.

On site containers would be unloaded via crane and then lifted into place once emptied. Containers would be co-ordinated to come to site when needed. Once containers are in place they would be painted the specified colour and fitted out with the desired program for the user of the space.

Context Responsive Structure

PV Panels

Opaque glazed panels

Glulam beam primary structure

Developed via a force algorithm, the roof structure is independent of everything in the main terminal. The design is responsive of site conditions such as wind and solar gain to make the most from the available natural resources on site. The panels will be fixed to the timber gridshell, providing different spatial configurations using light and shadow in the spaces underneath. The roof structure is designed to stand alone sculpturally in the event that the airport were to close/ fail.

“Living Façade” The primary structural containers work by supporting the suspended floors above. Allowing relatively large spans across the space. Instead of keeping the containers empty or for storage space throughout, extra programme has been designed to essentially live in the structure. A key driver in the deciding of programme was the need and its support to the Maldives.

The containers are staggered, giving opportunities to possibly create balcony areas along the space.

Having an inhabitable space that maximises use of the containers creates a system that creates resilience.
