In the year 2013 half an Empire State building was constructed in the city every day, an equivalent of 182 Empire State buildings in one year, a massive amount of architectural production for a single city. Chongqing has followed the default growth paradigm of isolated multi - tower - in - the - park developments located at the periphery of the city that are, by default, conceived in isolation; this paradigm fails to envision the concurrent architectural production within the city as a possible force that can be focused and utilized to shape the urban experience, reduce overall transportation time, reduce energy consumption and make evident the reality of the scale at which the city is growing. Scale, The next jump in architectural production proposes an alternative development model that capitalizes on the opportunities embedded within the unprecedented scale of concurrent development taking place in Chongqing. By understanding this development as a confluent force Scale proposes a system through which buildings previously thought of as single use become multi - use infrastructural parts of a much larger architectural object, a single "building made of buildings". Typical generically designed housing and office towers become the columns supporting city blocks turned elevated beams that assemble to form a new infrastructural object. Such an object fulfills the immediate programmatic requirements of the city below; education, housing, offices and public space as well as transportation are embedded within, giving the new architectural object the ability to intensify the gravitational pull of the city towards itself and serves as a marker showcasing the unparalleled scale of architectural production that the city of Chongqing is currently able to generate.

Ant6n Garcda-Abril Many thanks for your time, dedication, wisdom and continuous words of encouragement. I will keep the aluminum model but you can have the test piece. Joel / Jeremy Thanks for the invaluable advise and for your willingness to spend time talking about this thesis, your advise came at critical times and made it a lot easier to navigate this whole thing. Justin Lavallee For your generous help during the making of the aluminum model, I would still be watching the mill break bits if it wasn't for you, this and all the extra time you spent with me figuring everything out makes you the real hero in my book. Eryone 4 scale Thanks to Chris Green for killing with images. Grisha and Philip, your assistance in the last moments of madness was mission critical, many thanks.

However, recent developments in modeling tools (the scalelessness of digital space), fabrication (the increasingly seamless translation of this scaleless digital space into physical space), and the homogenizing pressures of globalization (the loss of local context), have upset these traditional registers, leaving the status of scale increasingly uncertain and in need of reformulation."'] It is this opportunity for reformulation that is most apparent in the one place on earth where architectural production has reached an expanded new scale, the city of Chongqing in central China. Architectural production in Chongqing has reached an unprecedented pace and scale, unfortunately this condition has not been considered as such, creating a situation where development in parallel misses the great opportunities that consolidation and scalar expansion bring. 8 scale Graphics exploring the current limits of scale in architectural production. The images show an exponentially expanding context with an overlay fixed size reference form as a stand-in for a potential architectural product21 julian ocampo 9 Chongq ing Is a major city in Southwest China and one of the five national central cities in the People's Republic of China (PRC). Administratively, it is one of the PRC's four direct-controlled municipalities (the other three are Beijing, Shanghai and Tianjin), and the only such municipality in inland China. The municipality was created on 14 March 1997, succeeding the sub-provincial city administration that was part of Sichuan province. As of 2010 census, the municipality had a population of 28,846,170. According to this census, Chongqing is the most populous and largest direct-controlled municipality in China, and comprises 21 districts, 13 counties, and 4 autonomous counties. -World's fastest growing large city, with annual GDP growth exceeding 15% 10 scale - Extensive support from the central government and its 'Go West' initiative and high visibility due to Chongqing's status as the only provincial-level municipality in inland China - Inland focus is structural and has underpinned strong economic growth. Chongqing has continued to see doubledigit FDI growth in 2012 - Cheap labor is not the only draw. Infrastructure improvements and favorable policies have successfully attracted key multinationals and their supply chains - Chongqing has established 'scale' and a strong reputation in its manufacturing sectors - Logistics real estate is under-provisioned - improving infrastructure and greater domestic and international integration is driving demand.

Over the past decade, the Chongqing municipality has seen increasing industrial specialization, particularly in its traditional heavy industry sectors. Significant mineral and other natural resources, as well as abundant (albeit lower-skilled) labor, have provided a considerable competitive advantage for the city to attract investment in manufacturing and chemical processing. 16 scale Furthermore, its healthy rivalry with neighboring inland cities, particularly Chengdu, has ensured that securing reforms and favorable policies, enabling it to remain competitive, continues to be high on Chongqing agenda. The increase in manufacturing and logistic capacity as well as extensive support from the central government and its 'Go West' initiative make the rapid urbanization of Chongqing a country wide priority.

With its relatively low current rate of urbanization at 53%1 and its designation as a pilot for rural-urban reforms, Chongqing's urbanization rate is projected to reach 60-70% by 2020. This goal, along with the city's inherent cost advantages (derived from its abundant land and labor resources), improving transport links and central government support, make Chongqing an increasingly attractive destination for domestic and foreign investors. 20 scale 1111111 jIllIllIllIlli 1111111 I 11111 It 1111111 I iii" 111 It 1111111 it I 11111 III It 1111111 it I 11111 1111111 I 'liii 1/2 Empire State Building a day 182 EmpireState Buildings a year Real State Built in Chongqing in 2013 julian ocampo 21 Chongqing A relatively small city until the second world war when military and heavy industrial production was moved into the city in order to secure it from Japanese bombardments.

It is what we resign ourselves to. It represents a lack of agency. A failure of vision. It is the least common denominator. Mediocre. Banal. Bland. Generic. It is what slips through when we look the other way, when we're distracted, when we're too busy, or when weve given up. And yet, the default also constructs commonality and cohesion. It can create a shared legibility, a visual language available 26 scale to a broad and diverse public. It is the field, the mood, the ground that enables the figure. The assumption is that design inherently denies the default, and that the default is by definition un-designed. Buildings are default, while architecture is its opposite - exceptional and deliberate. 31 In this chapter we explore what happens if we do nothing, If we offer no alternatives to the current growth paradigm.

It is in the interpretation and implementation of this analysis that the Ring gains agency, the ground below informs the formal / programmatic formulation for the ring supports and beams above; for example, in a heavily residential area there might be a lack of education and recreational facilities so the beams above will make up for the imbalance, always keeping in mind that the infrastructural and transportation components of the ring above are public and always open to the rest of the city. 4 scale ,-r 7-~ ~.p. ~ ~ -o i Residential Sites that consist mainly of residential tower-in-the-park developments Mixed Low Rise Office / Mid Rise Highest land elevation along the The most prevalent site typology, a mixture of new development and older mid rise buildings. ring, with a lot of govemment and healthcare facilities New Development Spaces within the city that are only now being opened to development, encompassing completely undeveloped areas. julian ocampo 45 Site Type 1 Residential Sites that consist mainly of residential tower-in-thepark developments 46 scale julian ocampo 47 r4 where Open space is seemingly abundant in the "tower in the park" model 48 scaie landing Open space is seemingly abundant in the "tower in the park" model ewe..
