Sky City One: la torre más alta del mundo… en 90 días!

Sky-City-One-torre-prefabricada-concepto

Durante más de dos años estuvimos siguiendo la construcción del edificio más alto del mundo, el Burj Khalifa, pero puede que superar su récord de 828 metros no necesite de tanto tiempo, porque una compañía china (BSB) está dispuesta a construir uno diez metros más alto, pero en tan solo 90 días!!

Para hacer más creíble esa proeza arquitectónica, hay que tener presente que la constructora BSB (Broad Sustainable Buildings) ya fue capaz de levantar a finales del 2011 un hotel de 30 pisos en tan solo 360 horas (15 días), empleando para ello un sistema de construcción prefabricado. Ahora están dispuestos a romper el techo actual con Sky City One: una mole de 838 metros (220 pisos), bastante menos esbelta que la de Dubai, que empezaría a construirse en noviembre de este mismo año, y se completaría en enero del 2013. Todo ello en la ciudad china de Changsha (capital de la provincia de Hunan).

Imaginamos que el sistema de BSB (ver vídeo del hotel más abajo) será adaptado a Sky City One, fabricándose en taller un 95% de todo el rascacielos, y luego ensamblando en el lugar en ese tiempo récord todas las piezas. Así que estaríamos ante el edificio prefabricado más alto del mundo, que contaría además con importantes características sostenibles: con vidrios de cuatro capas, 15cm de aislamiento térmico en fachada, habiéndose empleado para su construcción la quinta parte de la energía necesaria para un edificio convencional similar.

Si bien BSB parecer haber firmado ya un acuerdo con las autoridades locales de Changsha, el proyecto aún está pendiente de ser aprobado por el gobierno central. De construirse, allí dentro podrán vivir más de 100.000 personas.

Chinese Developers To Build World’s Tallest Skyscraper…in 90 Days!

Skyscaper chart via CNNGO

In December of last year, Chinese developer Broad Sustainable Building (BSB) constructed a 30-story hotel prototype in 15 days. 360 hours. Seems they were just getting started. The construction company has announced plans to build an 838 meter (2750 feet) tall skyscraper in Changsha, Hunan PR, and they say they’ll do it in just 90 days. 2160 hours!

As CNNGO reports, ‘Sky City’ would become the world’s tallest tower, eclipsing Dubai’s Burj Khalifa by just 10 meters. While that building took some 5 years to complete, the new superstructure, estimated at RMB 4 million ($628 million), would not only be far cheaper than rival skyscrapers (compared to Burj’s $1.5billion price tag and the $2.2 billion Shanghai Tower), but will also employ sustainable building techniques and systems unheard of at such scales. BSB says the 220-story tower, which will offer 1 million square meters of occupiable space linked by 104 elevators, will consist almost entirely of prefabricated modules that will be stacked on site–the key to the neck-breaking construction times that the company is promising. The building will also feature innovations such as quadruple glazing and thick (quake-resistant) exterior walls that will significantly cut down its energy consumption. The company hopes that Sky City will receive the necessary approval to break ground by November of this year, with the project’s completion following in January 2013.

Re-Thinking Shanghai Proposal / Vinícius Philot, Fabiano Ravaglia and Gibran Duarte

In their proposal for the Re-thinking Shanghai competition, Vinícius Philot, Fabiano Ravaglia, and Gibran Duarte aims at transforming the big metropolis through biological methamorphosis. In their “Let’s paint Shanghai with fireflies” design, they give thought to the question, How could we make Shanghai, an already trend setting city within Asian and global scenario, also a reference for urban sustainable growth? The firefly system will be a sub-effect of a new way of thinking the public space. More images and architects’ description after the break.

Living in a huge city as shanghai has never been easy and probably will never be. Big metropolis tend to be cruel with its inhabitants, offering enormous distances to be transposed, crowded places and other difficulties we are so used to face in a daily basis. Suhzhou creek has a central paper on Shanghai`s urban dynamics and has been a spot for Chinese government`s public interventions in the last decades, mostly near the intersection with Huangpu River with Pudong`s stunning and emblematic skyline.

There have been efforts towards water purification, creation of public spaces and urban spots such as art districts and shopping areas. However, we want to address Suhzhou as a wider zone: the one connection central, downtown Shanghai to other peripheral areas.

In a macro scale, modules will be combined identifying special needs along each section of the creek:

Module 0 – Flow – creekside firefly farm and parks;
Module 1 – Social -circle benches;
Module 2 – Covered – tiled topography, smart roofing;
Module 3 – Proménade – algorithmic archways;
Module 4 – Day – museums, libraries, gardens;
Module 5 – Night – restaurants, pubs, night clubs;
Module 6 – Mixed – sports centers, arts centers, bike parking lots, subway and train stations.

Bright city lights, usually cast by skyscrapers and neon signs, will now have a different meaning, creating beautiful landscapes and being used combined with museums, art and sports centers, night clubs and many other urban hardware. Suzhou shall have its role revisited and reinvented.
