“Greater Jakarta”: estimated at 25milion inhabitants (2nd largest urban area in the world).
Visitors/city-users increase the congestion: severe traffic jams and overcrowdings ocurring almost every day.
40% of Jakarta is below sea level: air pollution, waste management, drinking water shortage, flooding (due to clogged sewage pipes/waterways, savage urbanization and deforestation).
Major buildings, highrises, services and residual public space are occasional and poorly connected, separated by endless traffic times. Seemingly, no solution.
The 2nd Chance: Jakarta Layer_02
Imagine a new, physical urban level slightly wrapping the traditional city.
Trying to envision the future of Jakarta for this competition, our attention was to choice carefully the object of speculation. We intended this brief as an opportunity: finally liberated “from petty politics and bureaucratic planning”, we tried to make an happy revolution to the urban scale, and beyond.
“Gotong Royong” as a continuous monument to the coexistence.
Jakarta Layer_02 integrates public infrastructure, public spaces, commercial, touristic, leisure and work functions, energy and water accumulation/production facilities.
The super-structure is 8m thick, and contains in depth one- or two-storied spaces. Tridimensional macro-holes, accurately positioned to respect settled distances from existing buildings and public spaces (diameters ranging by 75m to 350m), are designed to have a crucial contribution to the form-factor resistance. Smaller voids remain between the structure of the space-grid, to reduce weights.
In the wet season, the abundant rain is captured in special multi-stage osmotic filtered tanks, and so given back to public as sanitary water.
The super-slab is shored up at the height of 230fts (70m) by mixed vertical supports, such as structural reticular pylons or entire reinforced new buildings, containing lift systems and stairs to reach the Layer_02 level, apart from water pipes, drainings, electrical and data lines . All the support structural system is arranged at the ground level in urban plots still free of buildings or siding main streets, on public property spaces.
Main accesses to the Layer_02 are arranged near huge new parkings and busway stations, directly connected with the parallel and efficient transport system above (monorail/maglev).
To test it, we choose the condition 2 (im)mobility/”reshuffle”, pulling down a sample of the Layer_02 measuring 2.500m x 500m (1.250.000m2), oriented N-S over the joint between Jalan Sudirman-Thamrin and Jalan Mohammad Husni Thamrin. Pratically, a condition 2, remixed on the north side (congestion+access to the urban nucleus).
“And” is better than “Or”
What is Coexistence in Jakarta Layer_02? What we intend for Gotong Royong in this project?
Recipro-City: a Jakarta over Jakarta which not create a negation, a destruction, or – at worst – further congestion of the city we know today. Jakarta for us is Layer_02 and the original ground layer. Simply, the upper one supports the today-Jakarta, and can solve severe problems otherwise impossible to approach.
In other words: formal and informal; real and utopia; discontinuity and coherence; ended and endless.
The one of them contemporary with the another.
