abstract On 23rd January 2012, researchers at Tokyo University stated that â&#x20AC;&#x153;there was a 75% probability that a magnitude 7.0 earthquake would strike the (Kanto) region in the next 4 years.â&#x20AC;?1 Tokyo is the largest city within Japan and is incredibly densely built, supporting around 13.2 million people. This coupled with the countries geographical position between 4 tectonic plates poses very serious problems following a potential major earthquake within the city. The research sets to act as an example for other disaster prone cities around the world as vulnerable settlements of people devise new/ old methods of dealing with inevitable, cyclic problems such as earthquakes. By questioning current practices of earthquake mitigation, the research sets to develop improved methods of mitigation that do not rely on architectural or engineered mono-function approaches (which is currently almost always the case). By developing a multi-faceted system/design, the research aims to show that a problem such as Tokyoâ&#x20AC;&#x2122;s imminent earthquake cannot be solved with one standalone design. Rather it is a whole set of multiple interventions that can act accordingly at different time phases and scales, which will begin to interrogate how a city can function before, during and after a catastrophic earthquake event. Questioning current practices in Japan will allow for an understanding of the issues faced following an earthquake and will allow for understanding of where changes can be developed from existing techniques. The research shows how landscapedriven design techniques can be considered as a valuable tool for earthquake mitigation, as well as the research functioning as potential tool for other vulnerable cities around the world facing similar issues.

process process diagram - detailed this categorization diagram shows the different design scenarios and the step by step nature in which each design was formulated. This diagram proved a valuable tool in understanding how each design scenario was quite independent in their outcomes, but also connected in a number of ways (through the categorization using the keywords). The diagram responds to the systematic approach that has been interrogated within this research and visualizes the connections occurring between the different tests. This diagram became an integral part of the research as it documented the notion â&#x20AC;&#x2DC;the sum of parts being greater than the wholeâ&#x20AC;&#x2122; ie. The research develops a systematic approach, with multiple designs. These designs function together, to solve problems associated with Tokyo, not a single design which encompasses this.

layout_document The following document is an accumulation of a range of scenariobased tests which function both independently from each other, yet also in conjunction at a series of different time scales. Scale of approach dictates the chapters within this document whilst each scenario attempts to independently tackle a particular issue(s) within its own associated time phase(s). The research suggests that a single-scale and single-solution design is not the answer. Rather, combined systems of approaches which function at different timescales and within different contexts are added together. Using this methodology, a 'stacked system' approach allows for a larger system to not be ruled exempt, when one or more scenario may fail. The document is designed to be read in a non-linear fashion, where chapters and scenarios can be read independently and then interrogated against other scales of approach and scenarios. Although for reference, a plan is located at the start of every chapter and a combined plan, located on page 172 for reference. The research aims to document current earthquake practices within Tokyo, adapting them to better suit their environments and connect with the people who will use them in the event of a disaster. Although disaster function is a primary motive of the designs, it is critical that the designs function on a daily basis, not laying dormant like many of the other existing mitigation designs throughout the city. The design scenarios have been developed within a particular method of approach and as a result, worked quite chronologically in their unpacking of the issues facing the research agenda. The scale of approach changed with each new test and working within these particular scales provided a new method for categorization of chapters within the document. A further set of key terms categorize the scenarios, questioning key motives, issues and reasoning.

Design Scenario 0.1 questions the need for escape and dispersal of large amounts of people following a major earthquake event within the Sumida site. This particular site is incredibly susceptible to damage due to the fire hazards from Edo Period housing typologies, as well as the fact that the area is built on reclaimed land and the chance of liquefaction within the site is incredibly high. The need to move people along designated route(s) to safer areas is key within an earthquake situation, as people need to move away from these effected areas into other less-effected areas.

amass + at this point in time a clear understanding of the seriousness of the problem facing this site becomes clear.

background The design research interests have originated from a previous studio (After-Landscape) run in second Semester, 2012 taken by Dr. Marieluise Jonas. The studios aim was to produce a handbook for developing resilient townships in tsunami prone areas of Japan, following the events of the 3/11 earthquake and tsunami. The trip encompassed study, undertaken at Tokyo University, as well as on-site evaluation and meetings with local villagers effected by the tsunami that struck their small fishing village of Shibitachi, Miyagi Prefecture, Japan. Having witnessed first hand the destruction, which has shaped the coastlines of Japan, I was in awe of the resilience and acceptance for the inevitable that the local people had for withstanding such testing conditions. The intent for the research was to develop and build on the understanding of what was learnt from the time spent in Japan last year, now applying this to an urban context within the city of Tokyo. The research aim at the beginning of the year was to develop new ways of disaster mitigation for dealing with an expected catastrophic earthquake within the next 4 years. The formulation of the research question came through initial investigations into current practices of disaster mitigation, mainly questioning how an implementation of green open space network could be considered a much more viable option for mitigation within the city, compared to currently employed singlefunction architectural or engineered solutions. The problem facing these single-solution designs occurs once they are implemented, laying dormant for many years in anticipation of a catastrophic event but left largely untouched or utilized. By cross-programming a landscape-centered design, the need for everyday usage could be addressed, not only providing action within a disaster event, but also within an everyday context also. Some of the questions generated from this initial investigation included:

What are the real risks associated with the city? Where is the most dangerous area? Why is this area more susceptible than other areas? What can help mitigate such problems? What is currently in place/what is occurring? How can the notion of plugging into the existing be utilized?

initial research title + question

Inevitability-now Pre-emptive landscapes for changing spatial, environmental and economic conditions. What is the pre-emptive landscape? How can methods of mitigation design, be adapted and tweaked to be applied elsewhere in less-equip cities? How does the landscape react to changing environmental, ecological and economical conditions? What is the role of the Landscape Architect in â&#x20AC;&#x2DC;crisis landscapesâ&#x20AC;&#x2122;? How can new application(s) of design intervention aid in the buffering of such disasters?

How has research question changed? The initial research question was incredibly broad in its intent, questioning how currently employed techniques within Tokyo could be applied to other less well-equipped cities around the world. After partaking within initial research and understanding the very serious threat which stood in front of Tokyo, the intent of the research shifted from developing and adapting current strategies in Tokyo and Japan for other sites, instead focusing internally on the struggle to best prepare the city before an expected catastrophic event. Initially the research questions were attempting to solve single weekly scenarios, it was not until these scenarios began to be questioned against each other and the broader framework of the research, that the research questions began to encapsulate the entire body of work and set a precedent for further development of the project. The research question for each scenario can be located within the cover page of each scenario test and a timeline of the chronological order and time phases of each research question can be found in the appendix of this document.

research OBJECTIVE The objective of the research is to develop a range of methods, which question current practices of earthquake mitigation within Tokyo. Currently mitigation within the city relies heavily on architectural and engineered approaches to solving issues surrounding a disaster. The problem with these particular approaches is that they are designed to only function within the disaster event and are not programmed to function within an everyday setting, laying dormant for the majority of their lifespans. The ambition of the project is to develop a range of differently situated designs, which tackle associated problems and issues at their respective scales and time phases. By understanding the different issues at these time phases, a rounded-approach to the overall problems facing the site can be interrogated. It is through this interrogation the real needs and

processes, which are vital before, during and following, an earthquake can be understood; and an appropriate design realized. By investigating what is currently in place for mitigating such issues on site, designs that are developed can be critiqued against what is really occurring on site and currently in place. These critiques can be investigated and understood; and positions regarding the success/failure of particular scenario realized, through either aligning, contrasting or disregarding the precedent. By evaluating different scenarios together, a larger synthesis scenario can be formulated, one which will attempt to engage a number of different complex issues facing the city in the event of an earthquake.

research FRAMEWORK The research framework is developed by initially using a series of different design iterations that locate themselves within a range of different time phases. Within each design scenario, precedents are recognized that help to frame the design. From these precedents, the design outcome can align, contrast or reflect on what the precedent offers, learning from what is already in place within the current design environment. After developing the scenarios, a quick evaluation of the design can be made (comparing back to the precedent) and the most successful designs can now be crossprogrammed together, mutating the designs to begin to solve a range of issues at a number of different timescales. After the new design has been developed the scenario evaluation diagram is applied which visualizes how each scenario solves a range of key issues surrounding the design. Given a rating of 1-5 (1 least successful, 5 most successful) an overall judgement of 20

the success/failure of these tests can be made. Again by selection, the most successful design scenarios can then be further mutated together, developing a final synthesis design that can begin to respond to a range of complex issues facing the site. Precedents and further evaluation are now implemented, whilst a projection for future endeavours can be made and reflection of the final outcome developed. This is again brought back to the initial design research problem and precedents, where an understanding of the process and development of the framework can be realized.

design scenario approach The design approach begun by looking at a number of different associated time phases of the earthquake and developing designs that addressed issues surrounding these moments. For example: a wayfinding device was designed, situated in the period of time directly following the earthquake where people could move along designated routes out to the safety of lesser effected areas. This approach was valuable as it allowed for free form design that only attempted to solve particular issues at these times. The design outcomes generated, only functioned within these phases and thus were functioning more or less in the same way that the current methods of mitigation worked. The design approach then shifted its trajectory to then question these singlefunction designs against each other, developing a new series of scenarios that began to question a range of different issues and time phases

together into one design. Through the development of these scenarios a new layer of detail within the designs became apparent, successfully designing a range of different mitigation tools which could then be questioned against each other for further development.

research for successful mitigation devices. Not only does it fufil it's key role as a mitigation device but also will function as a successful design when this connection with users is established.

Early within the research, an underlying theme has involved the notion of hardware versus software. Within Japan, the current mitigation techniques are now considering this theme as an understanding of the limitations of design interventions versus the potentials to train people for mitigation purposes. In terms of cost effectiveness, training people to understand risks associated with disaster remains an effective tool for mitigation within the city and when this can be coupled with design intervention it remains the best method for mitigation. Connecting people with the new design sites remains vital within the

RESEARCH APPROACH Through the process of the research, the understanding of a â&#x20AC;&#x2DC;stacked systemâ&#x20AC;&#x2122; became apparent as a means to tackle somewhat very different issues, yet maintain the ability to attempt to solve multiple problems facing the site. This notion of the stacked system came into realization through an understanding of the term fuzzy logic: a degree of truth rather than a simple yes or no solution. When considered in this project, certain elements of the design may be more successful/appropriate at different times. Because of the uncertainty of the problem facing Tokyo, the ultimate reality is that no one exactly knows where the earthquake could hit and what exact damage it could cause. Thus, a range of solutions that could work more/less successfully at different timescales can be developed, understanding that there are differing degrees of implementation through different levels of destruction.

This method of approach can now contribute to my own design practice, by developing a range of different designs and then cross programming them I am able to produce a range of potential designs and select what I deem to be the most successful to be developed further. The notion of evaluation is something that is crucial within this approach and the scenario evaluation tool became a valuable tool for visualizing the success and failure of different design scenarios.

disaster? Disaster can be classified as event where lives/objects lost, scale dependent on people involved or injured, generally measured by economic, cultural or social loss. There is varying degrees of intensity of disaster and measurement can come from, (but is not limited to) people deemed missing, amount of injured, homeless as a result of, total evacuated, overall monetary loss and insured loss. The effects of disaster vary greatly but the potential for disastrous effects within this site following a major earthquake are considerably high due to a number of different occurrences. This research aims to investigate and understand the associated issues and develop a range of scenario-based tests which aim to give a priority towards landscape-based design efforts.

UNDERSTANDING TOKYO

sumida-ku design site

“This city is a process not an 1 artefact.” Tokyo is an overwhelming city of immense size and variation. Having been lucky enough to partake in a studio last year that travelled to Japan’s tsunami affected regions (Tohoku) if the opportunity presented itself I knew I would try to come back to further develop my interests within post-disaster design work. The following exert is from my sketchbook which I carried with me whilst travelling to Tokyo for the first time.

“The city is a buzz with electricity and in a place full of millions of people, creativity and ingenuity is all around. Everywhere I looked it was a feast for the eyes, bright colours everywhere, something interesting and different lurked around every corner. It is this with this intensity of population where new trends are born, new styles adapted and new inventions take flight. The shear size of the population of the megalopolis is daunting, close to 3 times the population of Melbourne, the city is in a constant state of caution from natural disaster, mainly earthquakes in the cities. It is this common threat, which all Japanese are aware of; and generally speaking are perhaps the best prepared for any such disaster in the world. It is with that thought in the back of their mind that they go about their daily lives with such gusto. Precision and detail is everywhere, nothing matches yet somehow everything works.” Having seen first hand the power and destruction that natural disasters such as a tsunami can cause; and inevitably shape Japan’s landscape, I was eager to tackle a complex urban issue associated with natural disaster(s) within Tokyo. The suceptibility of the city towards disaster was something that interested me and its ability to continue to rebuild time and time again following catastrophic events.

â&#x20AC;&#x153;Roads and trainlines run over buildings, expressways wind themselves over rivers, cars can drive up ramps and onto the rooftop of a six-storey building, the huge volume of a golf practice net billows over a tiny residential district.

Travelling with a Melbourne University design studio aided by Dr. Heike Rahmann and Dr. Marieluise Jonas, I visited Tokyo for a second time. I was well aware of what to expect when I finally touched down. The city is chaotic, full with energy and excitement. There is a constant contrast between traditional Japanese values and a stark modern megapolis. The entire city is stacked, layer upon layer going from the ground level up and the same again below. With the vast expansion of the city, planners were unable to cap growth in many areas of the city, thus huge areas are poorly planned with a mish mash of different styles and layouts. This coupled with the fact it is one of the most earthquake prone areas in the world leaves the city at a constant state of vulnerability. One prominent occurrence within the city of Tokyo is the repetition of the 2

Given the shear scale and number of poorly constructed homes within the city, new methods of mitigation need to be developed to mitigate disaster and ultimately limit lives lost following an event.

The Tokyo mappings (left) look at the context of the city and how it has exploded in size and has grown to engulf many smaller cities on the periphery. The series also shows us that large parts of the city on the Tokyo Bay are incredibly susceptible to liquefaction (mainly due to poor planning: building below sea level and land reclamation). This coupled with the fact that the city houses an ageing population (with negative growth) makes the whole situation of an earthquake within this city seem dire. By using the existing chaotic network of infrastructure and plugging in new designs into the research, it aims to find new ways of dealing with the potential crisis that the city will eventually face.

textual Precedent played a large part in helping to understand current practices and occurrences in different disaster-prone regions around the world. This page documents different built precedents that act as both anti-precedent (inaccessible Chinese Evacuation Parks) – something that I did not want to pursue and documentation of landscape as infrastructure/ infrastructure as landscape (Higashi Shirahige Project) – on site occurrences, something that I was particularly interested in developing at the time. The second page documents a number of other precedents which begin to look at the methodology of different precedents such as ‘landscape considered as a dynamic system’, as well as previous student research from previous years. The Higashi-Shirahige development has shaped the way in which the research has considered different programs and systems packaged into a particular site. The precedent, located at the North West end of the site is a huge infrastructure design that acts primarily as a firebreak in the event of an earthquake (stopping spread of fire from vulnerable Sumida-ku side of the river, spreading across into the rest of the city). The design also has an inbuilt hospital for 2,000 people as well as various fire fighting tools embedded into the design, something that has been consistently questioned throughout the design scenario tests. Shanghai disaster parks have proved as anti-precedents for this research as they are virtually off limits to the residents who need to use them in the event of a disaster. The sites are locked to public, fenced off with barbed wire and are completely isolated from the rest of the city. This research develops designs which connect with the users of the site on an everyday basis, forming strong connections with site, thus when a disaster event may actually occur there is no doubt in the users mind where the safest local location is.

The design site of Sumida represents a very large problem for the city of Tokyo as it has been an area flagged as extremely susceptible to damage following an earthquake. Given the population of people living within the area, coupled with the housing typologies and urban fabric of the

neighbourhoods the government is scrambling to find ways to deal with the potential issues surrounding an earthquake within the city. It was for this reason that I chose this particular area of the city to develop the research and investigate how a design could plugin to the existing

infrastructure of the city and function within the earthquake time phase(s).

amass + at this point in time a clear understanding of the seriousness of the problem facing this site becomes clear.

housing typologies

pro: + potentially withstand earthquake + traditional + intimate (human) scale con: + does not allow for firetruck access + elderly population + fire hazard (materials used)

through street widening

A key issue with Sumida is the Edo Period housing typologies that are scattered throughout the ward. These wooden, densely built, 2 storey dwellings are generally occupied by elderly people, who have lived in them for many years. The main reason that this particular area is so susceptible to earthquake damage is due to the location of the ward, but secondly the building materials and layout of these neighbourhoods and their susceptibility to fire. In some areas of Sumida, cars cannot pass the streets because they are built so closely together! Thus when fires break out following a major earthquake, fire trucks cannot get into these areas to help residents to

safety and stop fires spreading. Currently the Tokyo Metropolitan Government has a program where it is buying up many of the properties within Sumida from elderly homeowners and widening streets and removing these Edo period typologies. The existing residents are then moved into earthquake-safe residential towers nearby, suddenly removing any close social interaction that would generally occur at street level. By shifting the interaction from the horizontal plane to a vertical one suddenly the social connections of the people who once lived in these existing typologies is no longer apparent.

liquefaction

Soil liquefaction describes a phenomenon where by a saturated or partially saturated soil loses strength and stiffness in response to an applied force, usually earthquake shaking, causing it to behave like a liquid. The phenomenon is most often observed in saturated, loose (low density or uncompacted), sandy

soils. This remains a key issue with the site in the event of an earthquake as the entire site sits on reclaimed land sitting above underground water systems. This problem has been addressed in the research by questioning multiple sites as evacuation nodes, diversifying risk and not allowing for one central site, open

to failure. By doing this, the notion of the ‘stacked system’ is realize¬¬d.

stacked system_ own term for understanding the multi-facet system of approach: if one part of the system fails, there is potentially others that can take its place.

A very complex set of problems are engrained in both Japan and Tokyo when considering the underlying issues of the country. By beginning to understand the context for which the country and city is at present, it becomes a vital tool for designing a responsive system which connects with users within the city and in a larger context the country. Many problems face the Japanese within this environment. Tokyo is a city is in a constant state of change and there are constant reminders of the struggle to find the balance between traditional and modern values. This research does not attempt to solve deeply engrained social issues facing the country, rather it takes particular aspects of underlying problems and attempts to solve smaller localized issues, which eventually begin to address larger problems associated with the city. The global financial crisis has hit Japan hard, meaning more people are earning less and more are working less. These somewhat negative occurrences actually provide larger opportunities for people to begin to interact with the urban environment they navigate within, making better use of green space and public services as people begin to slowly change the mentality of the 6 day working week. 43

unpack Following the numerous site visits undertaken a list was developed which began to document key ideas and occurrences that happen within the daily lives of people within the site. These quite simplistic observations acted almost as a trajectory points for further scenarios within the research (following the trip) as actual conditions began to be proved/ disproved rather than guessed. The highlighted symbols and examples were deemed to be the most important throughout these observations and were used to interrogate the previous work undertaken, as well as develop the new scenarios, which could respond to these observations. 47

“At the level of the home… talking to our hosts, the seeing of so much of life on the street was explained by the size of the houses – as they are so small and have such diminished sunlight as housing is so dense in parts of the city, people socialise out, to the extent that some houses are being built without kitchens as so little food is consumed in the house. So with bars, restaurants, shops and entertainments all around you, the house becomes now somewhere just to sleep.” 4 4

“Tokyo has already been edited to suit every possible 5 objective.” MADE IN TOKYO, BOW WOW.

PROJECT JAPAN, koolhaus.

Made in Tokyo was used initially as a precedent for its analysis and drawing style, drawn in isometric line work. It documents a vast matrix of different styles of buildings which have formed from Tokyo’s immense density and strain on land use. Upon reading, it was found that some of the documentation showed use of landscape as infrastructure/infrastructure as landscape, as well as cross-programming that occurred could also be used as a precedent when thinking about design tests. The gaps within their work that this research attempts to solve is exactly how to connect people with these particular sites and how disaster mitigation can be cross-programmed within these sites. The research critiques BOW WOW's lack of connection to context throughout the work and attempts to use the exisiting environment and conditions and begin to shape the built form accordingly.

The Metabolist movement in the 60’s and 70’s was at the forefront of progressive architectural thinking in Japan during the reconstruction phase of the nation following WW2. The book provided a great precedent for conceptualizing new ways of thinking about how the city could be re-thought and re-interpreted. What lacked within the movement was a sense of connection to context and a 'tabula rasa' approach to design outcomes. This research takes into account the surrounding context of design sites and connects users through clear and defined existing nodal points of reference. The text gave insight into conceptual visions of a changed Tokyo, not limited to conventional ideas or understandings.

RECONSTRUCTING KOBE, edgington. A3

PHYLOGENESIS, FOA.

Reconstructing Kobe provided a fantastic insight into the post-earthquake conditions following the disaster in Kobe, 1995. Providing valuable data and analysis, coupled with first hand accounts and graphical representations this book provided a great deal of knowledge when considering the effects of such a disaster on a Japanese city. This text gave a level of understanding of associated problems to the research, where initially it was at times assumed conditions. It added a level of detail and problem solving to the design test scenarios that was not previously present.

Phylogenesis provided an understanding of a graphical representation to compile seemingly very different earlier design tests with one another. Using a method of categorization and symbolism, the somewhat very different tests could then be read as a whole and the overarching issues/ideas can be drawn out from this process. The layout of the text provided the basis for the categorization diagram, incorporating all the design scenarios and separating them into a range of different sub categories including: time phase, scale, ¬outcome and condition.

THE FUTURE METRO. LANDSCAPE,

biswas.

BY-PRODUCT TOKYO, bertram.

Biswas, the author provides an insight of a foreigner looking into Tokyo and its surrounds. He gives accounts of how the city was formed and the forces that have shaped its landscape. This initial reading was the text which first began the interest in Tokyo and continued on through 2 previous studios. Written almost as a case study for future cities rather than an account of the existing. The text provided many of the quotations for this document and provides a great insight into the everyday occurrences of Tokyo.

By-Product Tokyo was a studio run by RMIT and the publication mimicked the analysis of atelier BOW WOW’s MADE IN TOKYO, and Pet Architecture. It looked more in depth as to the anomalies that occur within Tokyo and where they are located. It was used heavily as a precedent when considering vending machines as a streetscape driver for design scenario 0.6. The method of representation between this text and BOW WOW’s example were also emulated throughout the process of the research.

PET ARCHITECTURE, bow wow.

POST-BUBBLE CITY, bow wow.

Pet Architecture explores Tokyo’s ad hoc architecture that occurs as people use every amount of space possible to squeeze into the left over urban condition. Much the same as MADE IN TOKYO, BOW WOW investigates how these buildings occur, what systems/forces shape these left over spaces and their locations. Again, used heavily as a drawing technique for vending machine design iterations and will continue through to documentation of site whilst in Tokyo.

A comprehensive survey of some 70 small-scale house designs and projects of atelier BOW WOW that deal predominantly with the complexities of dense urban environments. 12 different conversations on urban and architectural issues are developed in this text and various precedents shown. Ideas regarding connection of people back to street level stem from readings on BOW WOW’s white limousine project and temporary school. This example provided a real outcome for community engagement (white limousine project) and served as an initial precedent for the final synthesis design scenario, which looked at incorporating moveable market stalls into new reclaimed sites within the city.

DATA FLOW 2, gestalten.

DOGS+DEMONS, a.kerr.

Dataflow 2 provided a visual precedent for many of the diagrams/infographic and layouts that have been used throughout the research. The text provides many examples of data visualization on seemingly complex data sets, representing them as legible, readable outcomes. This was something that was crucial within the entire period of the research.

Kerr writes about Japan’s current crises and paints a very different picture to the other seemingly positive reviews of the city/wider context of the country. He emotively describes current issues faced within Japan and does not shy from many disheartening truths. It provided a unromantic summation of the city, giving the research the ability to step back from the city and question what is really important when considering disaster mitigation in Tokyo.

“Tokyo is an experimental field where every urban trend appears for the first time,to be copied years later in other world cities.” 6 6

Metropolis NOW! Urban Cultures in Global Cities, Ramesh Biswas, p.34

â&#x20AC;&#x153;the issues facing this city (following a disaster event) are so large and complex, that any design within this research needs to rely on the fact that it will only be mitigating the problem. There is no solve-all answer to this problem.â&#x20AC;? - Simon Meade.

positioning_within la. This research uses the practice and work of ATELIER BOW WOW to theorize the research within the context of the city. The work of the firm interrogates the need for maximisation of limited space, cross-programming of design sites and the notion of "landscape as infrastructure/infrastructure as landscape". All which have been unpacked within the design research. A similar position has been questioned throughout the research, later adapted following the field trip to Tokyo in July. The research situates itself alongside currently employed methods of disaster mitigation in place within the city, by using primary and secondary openspace networks to develop a system of mitigation. The research questions: how programs and systems can

then be incorporated with context to their surrounds to develop sites that actually connect with the users?

This trajectory is something that is not employed on site at present, where a roll-out approach has been developed with a standardized approach that does not take into account anything other than space limitations of these sites. The research work of Atelier BOW WOW (through MADE IN TOKYO, PET ARCHITECTURE etc.) gives an understanding and appreciation to the complexities that occur, within this city amongst almost every neighbourhood. A strong interest of crossprogramming, especially of somewhat incompatible programs and systems is something particularly common within their texts. The changing of particular systems to suit their surrounds is another common trait within their practice and this mutation of individual programs has been developed throughout this body of research.

taken from textual analysis:

0.1. tennis court bridge + cemetery underpass, MADE IN TOKYO: Atelier BOW WOW

To date the work of Atelier BOW WOW has mainly focussed on small-medium scale residential and cultural sites, where they have developed a mentality of maximisation of site, something which is very necessary within Tokyo and Japan. Their work develops from seemingly under utilized or challenging sites, maximising space and individualization thorough a range of different techniques. Their research is something which is of particular interest to this body of work, rather than the built form they design. ÂŹ In terms of discourse, it is their research, methodology and interests of which are most aligned to the discourse of Landscape Architecture. Having great affection for the abnormal, home-made and mutated, their research documents what is of particular interest to the research within Tokyo. Their mode of representation has also served as a precedent for this research, using complex linework, axonometric drawings and select colours to highlight key points throughout the work.

0.2. House & Atelier + Tower Machiya Atelier BOW WOW

in practice Currently in Tokyo mega structures and single-function designs are used to mitigate disasters within the city. An example of such over engineering, though not related entirely to earthquakes is the Sea Wall.

One aligned project is HAT Kobe development by Yoji Sasaki, developed after the Kobe earthquake in 1995. Using resident-driven designs, the development was shaped by the community needs and what was really wanted by the people living there, rather than the ideals of the designers. This practice was developed after they realized that it was community engagement following the earthquake that was the biggest positive influence on people affected by the disaster 56

Scattered along most of the coastline of Japan, Sea Walls are huge concrete walls that disconnect people with the ocean and have been proven to not be effective in reducing damage following a tsunami. Even after the 3/11 tsunami which ravaged the coastline of Miyagi prefecture, they are still constructed, in many cases smaller than the actual wave that occurred following the tsunami. In Tokyo, engineered and architectural designs are almost used exclusively, where strengthening and tolerance takes priority over function and useability. One example is the Higashi Shirahige development, located in the North East corner of the Sumida-Ku site. Designed as a huge firewall, it limits the spread of fire from Sumida across the river by acting as a huge automated concrete barrier with huge closable entry gates and walls.The huge building only serves a residential and emergency function, nothing else. Not enough multi programming is involved within these designs and therefore many of the sites do not connect with people and are not understood as a mitigation tool within the city. This research aligns itself with the Tokyo Metropolitan Governmentâ&#x20AC;&#x2122;s current disaster mitigation system that establishes local primary evacuation sites, followed by secondary larger evacuation zones. These evacuation areas will be unpacked later in the document, though again, they are widely unused and many people do not even know they exist in their local neighbourhoods.

thus it was used as a model for designing the spaces surrounding the buildings in the development. My own images document some very common occurrences within Tokyo. Multi-layered infrastructure taking priority over the ground plane, a constant contrast between super modern and the traditional as well as extremely poor quality housing stock within Sumida-ku which creates a hazardous environment following a major disaster. Common current practices used within the city include media and broadcasting transmitting warnings in the event of a disaster, building practices which have been brought into regulation to strengthen buildings as well as training systems.

Current mitigation technique employed in Tokyo.

Simple engagement catalysts such as market nights, playgrounds and seating help in engaging users with a space. Seating is something that is widely overlooked within Tokyo, with many public areas not providing or actively preventing seating. By cross-programming seating with storage for evacuation or emergency equipment, these sites can remain functional in both disaster and normal phases.

positioning_within context. Currently a number of practices are undertaken within Tokyo that act to mitigate a potential disaster within the city. Some of these include: usage of media, disaster drills and preparation, use of emergency phone system (711), computer modelling and disaster management, as well as primary and secondary evacuation sites.

Disaster drills and community engagement: every year on the 1st of

September it is evacuation training day in Japan. It serves as practice for thousands of people who take part in the drills and attempt to prepare themselves for a potential crisis in the city. The ideas surrounding drills have not been unpacked within this research, but the techniques of community engagement, through the use of public open space have in the final synthesis approach. Because of such space limitations which exist in the city, newly developed localized evacuation sites will establish a greater local community

engagement, creating stronger, more resilient communities through social interaction.

Local evacuation parks: below is an example of a common local evacuation park, tucked away within a small intersecting road within Sumida-ku. Highlighted within the image is a tool kit of standardized objects, common within almost all local evacuation sites (space according). The problem with these particular spaces is that a roll-out approach has been employed across the city, these sites are poorly designed and upkeep is generally left to local residents. The spaces are incredibly un-prescribed, having little signage, connection to surrounding context or any cross programming. Thus the spaces are almost always unused, studies within the research, talking to local residents proved theories that people do not connect with these sites at all because they do not know they exist or what their primary function is.

0.1. Common local ‘Evacuation Area’, red highlights kit of parts which are applied to almost all sites across the city.

All designs developed throughout this research have questioned how context can shape a particular site. Without context, designs have no connection or grounding to the site which they are located within, meaning potentially the site could be anywhere else in the world and have the same effect on its surroundings. The research has strived to develop a range of tests that build on this notion of context, yet when dealing with a multi-faceted system which incorporates a range of different sites, it is unfeasible to completely redesign the fabric of the city through these designs. The research has developed the design scenario tests as a method of testing for a particular exemplar, with the aim for the site to be used as a model for further application throughout the city with differing outcomes and results. The research has aligned with currently employed techniques within Tokyo, yet a further level of programming and context shapes the sites into something different to what currently occurring across the city, unsuccessful and underutilized sites.

DEFINING PHASE

A very clear moment within the disaster timeline is chosen and a series of pros and cons are developed to determine the key ideas at a particular point in time. Examples of these key ideas could be the primary need for access to water for drinking or fire fighting, or the key infrastructure of a toilet system. A series of design ideas can be quickly produced which attempt to question these ideas and they are evaluated according to their effectiveness of answering the key issues associated in earlier development. From this, a design is chosen according to its effectiveness and then developed and presented for a weekly presentation. Feedback is then supplied and the design is reflected upon and can be potentially reworked or rethought to further suit the key ideas. The diagram (below right) looks at the planned stages of the year, including a field trip to Tokyo in the mid-year holidays. The diagram looks at initial ideas formed, realizations made after being on site and then adaptation after coming back to Melbourne.

SETTING/FRAMING PHASE

A series of different design iterations were developed, which attempt to solve a number of different issues at a number of different time scales involved in the process of a earthquake disaster within Tokyo. The diagram (right) is a diagram for the development of each design iteration and looks at what decisions were made to produce a design.

scenario evaluation diagram 1.

culture

The scenario evaluation diagram was a means of measuring the success of each design scenario. Based on a number scale of 0-5 (0 worst, 5 best rating it gives a personal opinion of the success/failure of a particular element of a design) the criteria diagram visualized independent aspects of the project and gave a whole perspective of how the scenario fared, not only against its self but also against other tests. The diagram acts as a valuable tool for seeing the short falls and strengths of the entire body of work when single design scenarios evaluations are stacked on top of each other, framing the work within the criteria and visualizing the rating scale denoted on the diagram.

Reference 0.1 documents an early attempt at a set of evaluation questions for critical evaluation of each scenario. The question set did not appropriately reflect the success/failue of each scenario as the questions were so broad and a number rating at the end of the test didn't accurately portray the end result of each scenario. This was later refined to become the design criteria diagram, which visually represented the success/short comings of each sceneario and could easily be compared with other design tests.

iteration 0.6

The research question for this project has changed considerably over the space of the semester. With each initial design iteration the question adapted to suit each particular test. When the tests began to be cross-programed together, the research question changed and began to encapsulate the wider research into a particular trajectory of research. Looking at the diagram to the left of this page, you can see that there has been particular themes that have remained present within different weekly research questions as well as some which may have only been present for that particular weeks design test duration.

research_ questions

Providing new multi-programed modes of mitigation and idea of the pre-emptive landscape has remained present throughout the duration of the semester. Initially the research aimed to develop new ways of thinking about and adapting to earthquakes by using selective points in time to intervene with and mitigate. The problem with this point was that there were so many related issues surrounding each moment that the only real way to tackle the problem was to pick one/two particular issues and maximise the effectiveness of a design in retaliation/alongside this. This approach became apparent in the later stages of the design iterations and once the notion of â&#x20AC;&#x2DC;picking your battlesâ&#x20AC;&#x2122; (only working with select issues) was realized, the trajectory shifted to:

how could these solutions could be mutated together to then eventually respond at a number of different time phases?

DEFINING PHASE

The development of this design iteration came from the selection of during-event time phase (between 1min1day). By using my design methodology diagram (right) I found that access to water, wayfinding through chaos and safety of survivors was paramount at this particular time. The diagram (bottom right) looked in further depth at the earthquake and the decisions, which would be made according to the situation a person, was in. The red circles indicate where potential design sites could be employed to help these journeys from point A to point B, escaping from such a disaster.

This precedent was useful in thinking about how lighting systems could be integrated into a wayfinding device within the city. This scenario questioned was in which differences could catch the attention of users, although lighting is not a viable option in Tokyo (overused), a vegetation system potentially could be. Although it was not unpacked very much through this particular design scenario test, it was later developed through scenario 0.7 (lighting design) so it became useful when potentially it could have been left behind.

Many of these were in densely built two-storey wooden housing areas.â&#x20AC;? 7 Reading firstly, then understanding a landscape is key to being safe within an urban environment. The ability to follow designated routes from affected areas of the city out to safer areas is something that was a key driver for this iteration. The task at hand was very difficult as the notion of route was interrogated. What was to happen if a particular route failed? How did people follow a route? What did they follow? Looking at currently used wayfinding showed that people had to connect with the route on some level. The route would potentially be iconic as intrinsically people would have to know they had to follow it to safety. Looking above at the example of the Tokyo Metro System, we can see that it is an incredibly overwhelming system. Yet, thorough colour coordination and a series of different line types the system works and is easily navigable (even for visitors). Looking into these principles I attempted to develop a navigable design for escape. As well as firstly addressing this problem, the need for water for firefighting efforts and drinking was also paramount. Through a series of filtrations and catchments water could be accessible at different points along the journey for people to access in times of emergency. 7

Understanding existing evacuation sites and routes was key to this design iteration. Although the routes were mapped I was not able to find any solid evidence of connection between these different nodes within the city. This iteration would plugin to the existing infrastructure and link up vital evacuation spaces and shelters, making them more accessible for large amounts of people to travel along them.

Through development of the design iteration, using single determined routes was not feasible as it meant that if one were to suddenly become inaccessible for some reason during the earthquake it would render it unsuccessful. Using primary and secondary routes became key to developing back-up strategies following such a disaster within this area.

The green insertion into the streetscape was a direct move to inject some form of greenery within the Tokyo streetscape condition. Within the urban context, especially within Sumida green space and vegetation is almost unseen within the streets. It was from this occurrence that this insertion could start to engage with people who saw it and then connect with the wider evacuation routes. existing condition

Although the design outcome may have turned into a micro insertion outlaid onto a larger network the ideas generated from this design intervention developed through a number of other iterations later into the semester. The ideas surrounding the intrinsic nature of connection with people to particular insertions were something which played out further in later iterations.

Understanding the limitations of an earthquake actually occurring was something which was particularly hard to factor into the design iteration. This model looked at the previous Kobe Earthquake as a measuring device and helped to understand how different people would navigate the site and make their own varied way to safety. The large cracks which ran through the model are modelled on what occurred in some parts of Kobe as sections of the city were literally torn apart, exposing the fault lines beneath them. Understanding the limitations of different people on site was crucial for the different character journeys which mapped out with pins and transferred into an autoCAD trace following making the model. More model images are situated in the appendix section of this document.

reflection The scale of approach let this scenario down, mainly due to the fact that it was smaller than the actual wayfinding beacons that it was critiquing. The ideas behind this scenario test were to bring vegetation into the streetscape, something which is relatively uncommon within many main roads in Tokyo. The aim of having vegetation was to grab the attention of people walking past, then connecting with the wider evacuation routes they were mapping out. Being the first scenario, it still had a major role in development of the project. Initially starting the move towards established and recognised wayfinding routes, carried on even through to the final scenario. Ideas regarding localization and self management in times following the disaster were also crucial in thinking about what people would need and what would help people to survive? The questions which arose from this design were: would people fleeing the effected sites follow a water purification system to safety? Is the scale of approach in line with the problem?

Urban plug-in(s) Pre-emptive landscapes within urban Tokyo. How can a plug-in within the urban context of Tokyo respond and have the ability to mitigate an impending earthquake within the city environment? What urban elements can form the basis for these plug-ins? How can these plug-ins function not only within a normal context but also within a pre/during/post disaster setting? keywords: urban, plug-in, tokyo, earthquake, function.

This scenario investigates a mutation of ideas of all previously undertaken exercises (1-5) into a new design, which can respond to different time phases and systems within the time period surrounding the disaster. The design questions a rethinking of common urban element within Tokyo, the vending machine and looks at how to reprogram it to suit a particular set of systems through plug-ins.

0.1. Harbour condition following Tsunami, Miyagi. 83

Working with Tokyoâ&#x20AC;&#x2122;s already chaotic signage (for almost every single thing imaginable) the challenge was to develop a clear understanding of the evacuation route through using the vending machine and streetscape insertion. Analysis of Melbourneâ&#x20AC;&#x2122;s CBD signage system proved chaotic in itself, yet Tokyo is in a league all of its own.

Design iteration 0.6, much alike Iteration 0.5 looked at how previous work could now be mutated together to respond to a number of different time scales and issues at the same time. Mutating the designs produced in the wayfinding device (iteration 0.1) with the memorial site (iteration 0.4) developed a series of potential trajectories for this iteration yet the key principle has been to plug into existing infrastructure to develop new methods or modes of mitigation. After some investigation the notion of the vending machine as an iconic, very-Japanese streetscape insertion became apparent. By using this already incredibly common streetscape insertion and tweaking or adapting its initial use, potentially it could serve as a valuable tool within the disaster time phase. The ideas, feedback and key issues generated from the previous wayfinding and memorial iterations were paramount for this design test and they remained a constant when considering the potential designs for this iteration.

The above tests look at signage in both Melbourne and Tokyo and the advertising that is prevalent within the streetscapes of both cities. A contrast between the 2 tests is developed when you consider the Melbourne journey was a 20min train ride with walking either side of that, compared to a 300m walking journey in a reasonably quiet street in Tokyo. From these findings it is clear that any design that attempted to develop a signage/wayfinding system would have to be vastly different to the existing conditions on site at present. 85

By-product Tokyo provided a valuable precedent study for this design iteration. A publication by a travelling RMIT Architecture studio, based on the Atelier BOW WOWâ&#x20AC;&#x2122;s Tokyo documentations, it documents the conditions of Tokyo in an almost scientific approach, the text helped understand the workings of Tokyo and form ideas on what should be documented and tested whilst visiting Tokyo.

cultural colour theory principles

Colour theory principles were investigated (above) as a tool for conveying ideas without relying on signage in multiple languages within the streetscape. This study lead to a selection in the colour light blue, which has followed through all the work as it has the same connotations in English and Japanese culture: meaning reliable, something which is incredibly necessary to convey in a post-disaster setting. 8

critique

what is wrong with signage in Tokyo?

- overwhelming amount of signage - each company/sign competes against its competitor to grab the attention of public - people donâ&#x20AC;&#x2122;t pay much attention because it turns into one mess of colour - people therefore do not pay much attention to real signage such as wayfinding or street signs

- can vending machines be plugged into a new wayfinding device for times of disaster?

The development of a matrix approach to design, was to consider designs which could act at 3 clear time phases (pre/during/post disaster). Because of the relative simple design of a vending machine, reprogramming and plugging in new designs into its original function was quite easy to achieve, thus an attempt at having the new design insertions to function at a variety of different time phases became apparent. Using wayfinding routes determined in previous tests the vending machines are placed at 200m intervals along the wayfinding routes, acting as a point of reference for people travelling along them. Developing a rule set for this iteration was also very important, as there are already so many vending machines within the streetscapes of Tokyo. Very clear definitions on how far apart along the existing evacuation routes they should occur, how they should function and what they should do following an earthquake were all considered when applying this rule set.

reflection This design scenario test questioned the streetscape and its role it could have in disaster mitigation. Using existing occurrences (vending machine) a re-design was imagined as a tool for mitigation. From this test a image style was developed (collage and 3d perspectives) and this carried through the rest of the work. Was it Landscape Architecture related? The colour blue has followed throughout the rest of scenarios also. For the criteria tool, it was effective at feasibility given there are so many vending machines in Tokyo but it did not have enough disaster function.

Scenario 0.7 investigates a re-evaluation of scenario 0.6 (vending machine), questioning how can a common object within the streetscape be re-programmed to function as a critical piece of infrastructure following a major earthquake event.

PRECEDENT Building on the previous chapters discussions on wayfinding within the streetscape this precedent in Chicago looks at an existing condition of â&#x20AC;&#x2DC;moonlight towersâ&#x20AC;&#x2122; developed as the first streetlights, but used literally to light up entire blocks with their iridescent light. The precedent was used as a means of questioning how an existing element within the streetscape could be reappropriated to function within a disaster setting. Given their clear height over their existing context of the streets below them, could these designs be reappropriated to form a wayfinding network, could this be applied within Tokyo? A similar style trajectory was developed further into this document in scenario 0.9, utilizing the Tokyo Skytree as a massive wayfinding beacon for the Sumida-ku site. Recognizing what is currently in place within the site is crucial within this research, as an already cluttered level of intensity occurs within the streetscape, so a design should generally work with existing conditions on site.

Critique An existing evaluation of the currently employed streetlighting within the streets of Tokyo was made, with little to no post-disaster function given the fact that many run on mains power. Light posts were chosen from a list of the existing elements within the streetscape, seen in the section elevation below. On the next page, a matrix was developed which documented a range of different streetscape elements and their potential usage within a post disaster setting. This design test scenario was developed with the understanding of having to fulfil a particular issue tested in a previous design scenario test. In this case, wayfinding was chosen which seemed a logical step considering their frequency and nodal qualities.

The design was developed to function within all stages of the earthquake time phase. The light pole tracked the movement of the sun, charging through solar energy retention and providing clear and defined wayfinding routes. The design of the light pole was a failure as the scale and approach of the design scenario test were not appropriate for the scale of problems associated with Tokyo, as well as the fact that the wayfinding lighting would potentially be one of the first things to fall over given a strong enough earthquake or tremor. Although this particular element of the test was unsuccessful, the coloured wayfinding road that taped into the existing wayfinding routes was, progressing into the final synthesis design and acting as a clear and defined wayfinding beacon in the event of an earthquake.

Using the light posts as a potential re-designed streetscape element was not a very successful design scenario test. Given the fact that in an actual earthquake it is generally light posts etc. that fall down first because of their narrow bases. That aside, this was the first design scenario to use the wayfinding road in the same way in which it was used in the final synthesis design scenario.

Future in/opportunities. Strategies for evacuation parks in Tokyo. How can a park react and be programmed to function to accommodate the massive flux of people inundating it following a major earthquake in Tokyo? How can the landscape provide a safe refuge area for effected victims of an impending disaster? How can a negotiation between hardware and software be considered when developing implemented designs/strategies or systems? How does this site adapt through specific time phases as people move to and from it following the disaster? keywords: react, programmed, function, flux, earthquake in Tokyo, hardware and software.

Design Scenario 0.2 and 0.3 looked at a designated evacuation site located on site and how it can be programmed to function better within the disaster time phase. Using a framework of sizing for 1 person, this could be translated onto the site and calculations can then be made about the amount of people who could potentially occupy a site following an earthquake event. The tests then questioned what particular infrastructures and landforms were necessary at particular points in time to manage the inundation of people onto these sites. Due to the size of the population and the lack of accessible evacuation areas within the site this design was necessary to understand the potential problems facing the site following an earthquake event. 0.1. Building aftermath following earthquake, Kobe. 103

DESIGN PHASE

We can see from the methodology diagram that again, water is crucial within this phase and in terms of a particular space for the people moving along these routes to come to, flexibility of infrastructure and understanding of limitations of space were crucial to the design. The design scenario test looked at how building and infrastructure could be considered either as independent infrastructure or to be crossprogrammed together. A mix between the 2, using existing infrastructure on site to plug into was favoured and this design was chosen to be further interrogated.

RESULT/EFFECT:

DEFINING PHASE

This design iteration focussed on a design solution post-event. By locating the time phase at such a point, was a direct move to act in a chronological order, moving on from the previous iteration 0.1 (wayfinding) that focussed on wayfinding device/route(s). Although the chronological order has been changed with the categorization of scenarios into scales, the methodology was to situate oneself within the disaster and develop scenarios as if passing through the site.

tatami_framework Understanding how many people could fit on a particular site was key within this time phase as to work out the limitations of each site within the area. Using the framework of the UNHCR handbook, the minimum amount of space for a refugee within a refugee camp was 30m2 (including infrastructure and living etc.). Using this framework I applied this to site and found that the site (at these limitations) could only facilitate around 150 people. Using the tatami mat as a new framework (still used to consider measurements in some architectural plans) I created my own new framework for a sleeping population that was limited to 4 tatami mats per person. Thus, the numbers applicable on site began to steadily increase and could begin to facilitate the 120,000 residents which reside in Sumida-ku.

precedent Beijing’s evacuation park implementation is a good step towards making the city a safer place in the event of a natural disaster or terrorist attack. Understanding the amounts of people available to fill these different sites is key when you consider the size of the cities involved in similar projects. The precedent (right) looked at how precise planning of crowd movement and numbers is being investigated more and more to understand how infrastructure will cope following mass inundation by crowds. Although the Chinese example is a great step forward into rethinking how the city could be reconfigured, many argue though that these parks are off-limits and locked almost all the time with private businesses now encroaching onto these sites because of the strain of land usage within the city. The aim of this design iteration was to primarily keep the main function of the park yet insert key infrastructure and systems into the existing condition so when the time came to be accessed it could switch to function within the disaster/evacuation time phase.

“Before the 2008 Beijing Olympics, the Beijing government set up 28 emergency zones and shelters around the city in case of natural disasters, mostly in parks and public spaces, and the number may expand to 300 in the next five years.” 9

Much like documentation in the earlier chapters of this document, the problems facing a roll-out approach to public open space within Tokyo have been critiqued. This chapter shifts its trajectory slightly, focussing on designated middlesized parks that are ‘equipped’ to facilitate inundation of people following a major earthquake as well as potential camping in the days following a major disaster. Much the same as the precedent study opposite, these sites are not suitably equipped to have people camping within the space due to the limitations of infrastructure and services which are not situated within the park system. This design test builds on the shortcomings of some of these designated spaces, developing an understanding of a system which ebbs and flows with the changing populations within the space over the course of a month. Using an almost modular approach, the number of potential beds on site can be calculated using the standard size tatami mat. From this, an understanding of the essential infrastructure necessary was devised, whilst documentation of what potential designs would need to be implemented within the design site made.

zooming in By developing smaller sets of strategies based within the park system the ability to facilitate large amounts of people becomes more and more apparent. Simple design strategies such as water catchment and filtering can facilitate access to drinking water that may not be available immediately following an event. By using a series of smaller insertions plugged into the existing infrastructure of the park system, the smaller parts in the system add into the existing site. The ideas surrounding water catchment and storage within the final synthesis design have developed from these initial tests into storage and access played out in this design scenario test.

The time phases documented on the next page-spread look at key moments in the disaster event, when through using the services and programs diagram (p.109) an understanding of key moments of changing spatiality and population size is realized. The 7 plans are based on these time periods, showing how the site could potentially be inundated by tents, when the program shifts from one of a park to a new camping program. The details document how key infrastructure can be utilized on site, providing essential services for people staying within the park. This understanding of inundation progressed through to the final synthesis design test, understanding the limitations of potential sites when the necessary shift from open space to camp site is made.

For instance, there is a need for storage of materials and other evacuation tools at point A: population 0, yet this is not necessary at point B: population 900, when the site begins to be filled with evacuees, the storage is cleared to begin to distribute the aid and other goods.

reflection A key question regarding this design scenario was how the site would change, not just spatially but visually when inundated by people wanting to camp? ÂŹTÂŹhe tests regarding potential systems and change in programs were successful in questioning how the site could change and this has followed thorough to the final synthesis approach also looking at a similar situation. Thinking about the gradual change in population on this site developed an understanding of the necessary infrastructure to support such amounts, understanding that an everyday use and feasibility of such interventions is crucial. An earthquake or disaster situation will only occur on an irregular basis, so having large scale infrastructure laying dormant on the site is not the answer to solving the problems facing this site (currently employed within Tokyo), rather it is about smaller scale interventions which can double with an everyday use.

Future Memorial(s) here. Space(s) for remembering people effected by the future earthquake scenario in Tokyo. How does a designed insertion into the landscape influence the people visiting the site for memorial of people effected and lost within an earthquake? How can this site primarily function as a memorial site, yet still be able to teach, train and influence visitors of the risks associated with living within Tokyo. How does this site connect further within the wider context of the city? How can the 7 Japanese design principles inform the design outcome on site? keywords: earthquake, Tokyo, memorial, teach, train, influence, wider context.

This design scenario locates itself within the future and at the end of the disaster time phase. It looks at how a memorial to an earthquake event could be designed and how to firstly memorialize people affected by the disaster, but also to teach other people visiting the site and warn them of the potential problems associated with living in a disaster-susceptible city such as Tokyo.

This scenario situates itself at the end of the disaster time phase (future) and looks at how to develop a memorial site or design to respond to the earthquake. The key ideas generated through the methodology diagram show that remembering, teaching and influencing visitors is vital, whilst establishing connection and maintaining dignity for people affected by the disaster are also key. This methodology diagram was a little different to previous iterations as it looked at keywords associated with an earthquake and then related these to existing design precedents. From these keywords 3 were chosen as having the most feasibility and then 2 were mutated together, resulting in crack and void being chosen as a design to work up as it responded to the key ideas the most successfully.

japanese design principles Kanso (簡素)

Shizen (自然)

Simplicity or elimination of clutter. Things are expressed in a plain, simple, natural manner. Reminds us to think not in terms of decoration but in terms of clarity, a kind of clarity that may be achieved through omission or exclusion of the non-essential.

Naturalness. Absence of pretense or artificiality, full creative intent unforced. Ironically, the spontaneous nature of the Japanese garden that the viewer perceives is not accidental. This is a reminder that design is not an accident, even when we are trying to create a natural-feeling environment. It is not a raw nature as such but one with more purpose and intention.

Enso Fukinsei (不均整)

Yugen (幽玄)

Asymmetry or irregularity. The idea of controlling balance in a composition via irregularity and asymmetry is a central tenet of the Zen aesthetic. The enso (“Zen circle”) in brush painting, for example, is often drawn as an incomplete circle, symbolizing the imperfection that is part of existence. In graphic design too asymmetrical balance is a dynamic, beautiful thing. Try looking for (or creating) beauty in balanced asymmetry. Nature itself is full of beauty and harmonious relationships that are asymmetrical yet balanced. This is a dynamic beauty that attracts and engages.

Shibui/Shibumi (渋味)

Beautiful by being understated, or by being precisely what it was meant to be and not elaborated upon. Direct and simple way, without being flashy. Elegant simplicity, articulate brevity. The term is sometimes used today to describe something cool but beautifully minimalist, including technology and some consumer products. (Shibui literally means bitter tasting).

Profundity or suggestion rather than revelation. A Japanese garden, for example, can be said to be a collection of subtleties and symbolic elements. Photographers and designers can surely think of many ways to visually imply more by not showing the whole, that is, showing more by showing less.

Datsuzoku (脱俗)

Freedom from habit or formula. Escape from daily routine or the ordinary. Unworldly. Transcending the conventional. This principles describes the feeling of surprise and a bit of amazement when one realizes they can have freedom from the conventional. Professor Tierney says that the Japanese garden itself, “...made with the raw materials of nature and its success in revealing the essence of natural things to us is an ultimate surprise. Many surprises await at almost every turn in a Japanese Garden.”

Seijaku (静寂)

Tranquility or an energized calm (quite), stillness, solitude. This is related to the feeling you may have when in a Japanese garden. The opposite feeling to one expressed by seijaku would be noise and disturbance. How might we bring a feeling of “active calm” and stillness to ephemeral designs outside the Zen arts?

118

precedent

By using the precedents above and below it gave an insight into what was the potential for this memorial design to become, using the method of working diagram, crack/void were chosen as the most suitable keywords to be interrogated, the precedents looked at a range of different examples from around the world questioned the keyword or related aspects to understand potentials of the design. The Shrine of Remembrance was a key precedent for this study due to its connection with people in Melbourne and the important role it plays within the city context (visible from the very top of Swanston Street). Using this example the intent of this design test was to develop the kinds of connection that aid in the teaching and understanding of the problems associated with earthquakes in not just Tokyo, but Japan also.

Using a mapping of the tectonic plates that surround Japan, the ceiling of the memorial allows light to penetrate through the interior rooms giving a sense of division and direction of movement. Using precedents of many different memorial sites around the world I was able to develop a design, which learnt from these previous examples but also took into account the notion of the 7 Japanese design principles. (previous page)

okhotsk plate amurian plate

Looking again at the principle of the Shrine of Remembrance in Melbourne, I wanted to capture the connection and importance the precedent had, yet did not want to emulate the prescribed nature of this type of memorial. Specifically using the principle of Yugen, I wanted visitors to develop their own ideas about remembering the people effected by the earthquake and be understated rather than over emphasised or prescribed.

reflection This design scenario test was the most unsuccessful out of the entire range undertaken within this research. The design was functioning purely as a memorial and did not meet the key criteria of the body of work: to provide some sort of function within a disaster setting. The design was not unpacked enough, using the potential of this site and design, the scenario needed to be multi programmed, utilizing the potential for inhabitable space or storage of key material and infrastructure. It was after producing this scenario that the research shifted its trajectory and began to really question how the future scenarios could interrogate a range of time phases ie. how could a new scenario function in all 3 time phases: pre, during and post? As evident in the criteria diagram right, overall it was rated as very unsuccessful. This is due to the fact that the design didnâ&#x20AC;&#x2122;t work at multiple time phases, didnâ&#x20AC;&#x2122;t provide a disaster outcome and did not engage with the context of the surrounding area.

Prior to this scenario (in chronological order) the 3 different design scenario tests did not question multi-programming or multiple time phases, situating themselves at each select time phase and attempting to solve associated issues, but not considering the wider implications in other phases. ÂŹ

This design scenario builds on what was developed and learnt in previous scenarios 0.1-0.3 (wayfinding device and evacuation park) and now mutates these ideas together to develop a design, which can respond to an earthquake situation at a number of different time scales and systems. This design rethinks how the urban fabric of Sumida-ku can be re-adapted to form new localized evacuation/public space areas within the ward.

PRESENTATION FEEDBACK REFLECTION

POTENTIAL REWORKING design methodology diagram

The approach for iteration 0.5 and 0.6 was quite different to the previous design iterations as experimentation with cross-programming different design iterations began to respond to different issues and time scales at the same time. Design iteration 0.5 looked at cross-programming the wayfinding device of iteration 0.1 and the evacuation park site of 0.2 and 0.3. The methodology diagram (above) used the feedback, which was received from the previous tests and looked at how these ideas could be mutated and joined together. When analysing the previous designs I wanted to move away from developing centralized evacuation parks/spaces because of the sheer limitations of space. By localizing evacuation spaces people could still use wayfinding to connect with this network of spaces but not necessarily have to all congregate in designated evacuation areas, limiting the usage of key infrastructure and services such as temporary water supply and tents for temporary housing. The diagram (above left) looks at this idea of smaller localized spaces plugging into the wider established evacuation routes from the city, limiting the need for mass congregation in the connected evacuation zones.

precedent

By giving people the opportunity to make the space into what they find most applicable (even if temporary), the sites will become far more successful because they engage the users with what is of particular interest and need. The HAT Kobe precedent is one of the only examples of modern developments in Japan at present that has been shaped by the residents who live within and around the site. Thorough analysis and engagement with residents has proven a design site that caters to the needs of people dealing with the site on a daily basis, something that has been developed through this scenario. In the same way, Atelier BOW WOWâ&#x20AC;&#x2122;s School Wheel and White Limousine project has interrogated similar issues. By developing a persons connection with the streetscape and neighbours, something that is lost more and more in Japan, a sense of community engagement and interaction is established through in this case a temporary school and dining table. Connection of people and community to these spaces and routes is key within the entire body of research by developing new public spaces that double as evacuation zones, the issues surrounding the older areas of Sumida (house removal) can begin to be tackled through the inception of these spaces. 0.1.

existing conditons Similar issues regarding existing condition of playgrounds within Sumida-ku are aligned with already discussed problems of local evacuation parks such as: roll-out approaches and context-less designs which do not engage with the local residents surrounding these sites. Following bombings that occurred in Tokyo during World War 2, there was a push to instate many of these small park and playgrounds within the urban fabric of the city as a way of increasing public open space. Many of these sites, still have not changed since they were developed more than 70 years ago, thus the spaces are incredibly uninspiring and lack any clear design motives. What this design scenario test engages with is how could potential new sites, be designed with context as a priority, facilitating connection with its surrounds and maintaining a primary focus of being able to provide a crucial role within a major disaster in the city. A playground can play a vital role within neighbourhoods for both children and parents alike, in this research the potential usage for playgrounds as disaster mitigation devices has been investigated.

Investigating a framework for the implementation of these new spaces, as well as having an understanding where these spaces would occur was vital for this iteration. By investigating the common household within the area and multiplying the scale up to block, wider block of city and eventually suburb, the amount of people within these areas could be determined. By understanding the amount of people within each area of the ward, assumptions could then be made about how many people each insertion could accommodate in a disaster event and the connection distances between each insertion also.

The re-introduction of green open space in Tokyo is essential if the city is to stand any chance of mitigating the potential crisis following a major earthquake within the city. Given the fact that per m2 Tokyo has one of the lowest greenspace indexes around the world, the urban environment proves very dangerous and susceptible to destruction in the event of a major earthquake. ¬

REMOVED HOUSING

land reclamation diagram

By working with the already existing building buy-up scheme from the Tokyo Metropolitan Government within Sumida, different sites around the ward can be reclaimed as public space rather than high-rise accommodation. The implementation of such a strategy would ultimately enhance and enrich the different neighbourhoods of the area by providing different types of public spaces, which would adapt and change to their surrounding context. These new public spaces would connect people back into the ground plane, establishing vibrant communities and interactions of people: much the same as to what was occurring before homes began to be brought up and developed into safer accommodation. Using the principles of the HAT Kobe precedent mentioned earlier, these spaces would change according to the context of a number of factors surrounding these spaces. By connecting people with these spaces they then can connect with the evacuation routes which link these spaces, ultimately establishing clear understanding of the residents and visitors alike of where to go in the event of a major earthquake within the city.

The design matrix has proved to be valuable throughout the body of this research as a tool to develop a entire range of fast, unrestricted design ideas and then evaluating them against each other. This process has worked much in the same way that the research body has been produced, developing a large range of potential designs, then having the ability to pick a particular iteration and develop further.

A rule set was developed which would determine the decision to choose particular designs for different neighbourhoods of the ward. The new public spaces would be determined by condition (size of the space being reclaimed), context (what was around this space) and proximity (how close was it to other existing spaces/services)?

For this particular design iteration the cross-programming of a playground and camping facility (during disaster event) was devised.

The population diagram above is a further development of the previous diagrams in design scenarios ÂŹ0.2 and 0.3 (evacuation park design) for this scenario, the number of potential plug-in programs were limited to water storage/access and waste storage. This particular site provided some very particular functions during the disaster time phase, mainly sleeping facilities and a localized meeting point which connected in with the existing wayfinding routes.

137

reflection This ÂŹdesign scenario was successful in beginning to develop ideas that later facilitated the advancement of the final synthesis design scenario. ÂŹIt was through this design that ideas regarding a larger system of mitigation became apparent. The ideas regarding context are very important within the research, through this scenario ideas regarding changes to different sites and how potential changes in site could also effect program and system outcomes. The design outcome of this scenario was potentially not unpacked enough, where more design could have been implemented within the reclaimed site. This has been consolidated through the final synthesis design which looks at a range of different design elements used within the sites, progressing on what was developed and learnt within these initial tests. The scenario evaluation diagram (right) suggests that technology could be paired with the site, connecting users in some way or developing new techniques for mitigation using technology. Social interaction within this site is something, which was also lacking, which has arisen through not crossprogramming enough designs or insertions within the space. Having multiple uses would increase numbers to the site, engaging with more users not just the users looking for a park or playground.

Altering urban fabric for earthquake mitigation. How can a green open space network be designed to rethink the urban fabric of a city and function as an earthquake mitigation device when the time is necessary? How does a combination of different plug-in designs allow the network to function at a number of different scales and timeframes, providing flexibility and functionality in the time before, during and following a major earthquake event? keywords: altering, green open space network, plug-in, functionality.

This scenario began to consolidate previous scenarios into a synthesis of designs, which could respond at a number of time phases and scales. The green framework links the existing major evacuation areas on site together through a linear park system, inserting green space within the dense site, acting not only as a critical wayfinding device but also a firebreak for the surrounding areas.

141

background This image documents the interest of people within Tokyo to use vegetation or greenery to limit the constant grey of buildings, roads and footpaths. Throughout the narrow sheltered streets there is a blurred edge between public and private, as people within their homes move things like pot plants, veggie patches and other greenery into the street in an attempt to liven the streets surrounding them. This design scenario test builds on this appreciation, developing a connection between existing evacuation zones and sites through a green framework.

green wall analysis

diagram By connecting existing evacuation sites together, the scenario creates a linear connection between the sites. This provides a key wayfinding route through the site, but also providing usage as a huge fire break, if the site was to be burning following a major earthquake. Having a large green conduit within the site allows for a huge amount of new open space, programmed with a range of different facilities for visitors to make use of during normal times.

precedent

Frederick Law Olmsteadâ&#x20AC;&#x2122;s Emerald Necklace in an example of a linear park system that was intended to connect the downtown of the city with the harbour in Boston, America. The design links many important sites together, using a linear path with ponds and a river to connect these sites together. This idea of connection was developed from this precedent, with the importance of connecting people with these already in place evacuation centres with the newly realized wayfinding routes. Because of the Tokyo's incredible density of housing and buildings, an instatement of such a design move would mean a radical shift in the way in which the site and potentially city operated. Because of the size of such a design, there was the potential to design a whole range of different spaces. Using principles developed in the previous design scenarios, the context rules can be used as a tool to begin designing such spaces. By developing a connection between existing evacuation spaces, a new design can develop the users connection with larger evacuation sites, ultimately aiding in mitigation in the event of a disaster within the city.

reflection This design scenario test was unsuccessful in questioning serious issues facing the instatement of a green framework within the site, mainly thorough not considering the wider implications of such large housing removals within the site. The scale of approach was successful in dealing with such problems but given more time, further interrogation of detailed design areas would have been beneficial. ÂŹThis scenario began to zoom out in scale, something that was very necessary within the research, as a wider system of mitigation was designed and developed through the scenarios. Working with such a large site, the connection of the existing scattered evacuation sites was crucial to developing a clear system of wayfinding and mitigation for people fleeing the site. Re-evaluation of the precedent builds on what Olmstead proposed as a simple park system, but this scenario developed a connection between a range of very important sites to ultimately facilitate mitigation within the site.

the pre-emptive landscape Altering urban fabric for earthquake mitigation. How can an altering of the urban fabric of a city, through wayfinding and evacuation design mitigate destruction within a city? How does a combination of different plug-in designs allow the site to function at a range of different scales and time phases, providing flexibility and functionality in the time before, during and following a major earthquake event?

Scenario 0.9 utilizes the primary wayfinding device on site: the Tokyo Skytree Tower and develops a central meeting point for people fleeing the site. It is built on design work from scenario 0.8 (green framework design) and questioned how multiple designs could begin to work together in synthesis to develop a system for mitigation.

149

condition The Tokyo Skytree Tower is located at the South West end of the Sumida-ku site. It serves as a visual beacon for the local area as it extends well above existing infrastructure in the skyline. Working with the existing, by utilizing this feature within the landscape, an iconic beacon can be re-designed as a now crucial piece of disaster mitigation hardware. The research has consistently raised the argument for use of existing infrastructure, already put in place as a means of not making the site more dense. By utilizing such an iconic piece of infrastructure within the site, users can have an immediate connection with the space and clearly understand the mitigation techniques employed within the design. Tokyo Skytree Tower context.

Utilizing an incredible vertical wayfinding beacon is one aspect of this design scenario, another involves the development of the Skytree station which sits at the bottom of the tower. Rail infrastructure within Tokyo plays a pivotal role in how the city functions, without it the city stops. By layering the 2 beacons together, this scenario begins to act the way in which the final synthesis design scenario does, using multiple designs or occurrences to provide a â&#x20AC;&#x2DC;stacked systemâ&#x20AC;&#x2122;: one which is not ruled obsolete if one particular element of the system fails. The site opposite is divided into 3 clear separate areas: the tower and its buildings, the existing neighbourhood below the tower and the station which sits in the middle of the site. The intent of the design is to link these 3 separate areas together, utilizing the Skytreeâ&#x20AC;&#x2122;s wayfinding potential but also developing a key meeting area for people to congregate following an evacuation. 150

By utilizing the rail infrastructure, the idea of using the tracks as potential space for people to use as wayfinding devices (following a shut down of the rail system) was considered. By developing emergency routes along the track, a defined and relatively safe site could inform the way in which people moved on site in the event of a major disaster. The station extension could then not only serve as a connection back to the ground plane for people walking towards the Skytree but also serve as a valuable connection between the local neighbourhood and the Tokyo Skytree development.

projection At this point in time the accumulation of a number of different design scenario tests being combined together as one synthesis scenario was recognized as an achievable outcome for the final design scenario test. As such, this design scenario merged into the final synthesis approach, shown in this chapter is a range of initial drawings and ideas before the synthesis design was formulated. After realizing the potential for the synthesis, this scenario was left undeveloped and redefined within the synthesis to be combined with a range of other select designs.

The Pre-emptive Landscape. Altering urban fabric for earthquake mitigation. How can an altering the urban fabric of a city through wayfinding and evacuation design, mitigate destruction within a city? How does a combination of different plug-in designs allow the site to function at a number of different scales and timeframes, providing flexibility and functionality in the time before, during and following a major earthquake event?

This is the final design scenario test within the research body, which looks at developing a synthesis of 3 correlated designs and how they can function within the site. The systematic approach develops a range of sites and routes. Developing the idea of the â&#x20AC;&#x2DC;stacked systemâ&#x20AC;&#x2122; and questioning how such a design could mitigate disaster within the city, but also change the fabric by increasing green open space within the site.

155

As mentioned, this design scenario test looks at how a synthesis of ideas can contribute to a system of mitigation on site. 3 designs are involved within the synthesis; reclaimed local evacuation sites (developed from scenario 0.6), a wayfinding route, connecting these sites with the existing evacuation zones on site (developed from scenario 0.1) and finally the design of an evacuation area, through the use of a station extension (developed from scenario 0.9). That is the chronological order in which this system is applied; yet the layout of this document altered the order to be read as station extension design, wayfinding route and finally reclaimed site design.

station extension contd. The Tokyo Skytree Tower is visible from the majority of the entire site and thus acts as a wayfinding beacon for the local area. With this in mind, the ability to link new reclaimed evacuation sites (within this synthesis approach) with this site became crucial in developing a site for people to flee to, providing it was not safe to stay within and around their local evacuation sites. The design uses the existing infrastructure of the Tokyo Skytree station and creates a link between the surrounding neighbourhoods, the Tokyo Skytree and surrounding development, as well as the newly established wayfinding routes. The site aims to act as a final port of destination for effected people travelling along these designated routes, where they can congregate and meet with friends and family, deciding if it is safe to return back to their homes or to continue to flee over the river and to escape off the site. Going back to one of the initial design diagrams (right), the Tokyo Skytree is set to act as a one of the larger nodal points connected within the system. The effected area within the middle of the diagram is the point of escape, where people would travel along wayfinding routes to smaller nodal points along their journey. Eventually they will congregate at a larger site, which is where they can re-evaluate their situation and make a decision to either stay or go from the site. ÂŹ

As mentioned earlier, the station extension creates a valuable connection between the somewhat isolated sites of the existing neighbourhoods, Tokyo Skytree station and Tokyo Skytree Tower and development. Acting as a conduit, it has the ability to connect people with the somewhat isolated neighbourhoods below. The design of the extension took a step back after the realization was made that the design was more about bringing people travelling along the wayfinding routes to filter through to the surrounding streets, not just the station. Thus, extremely large numbers of people can occupy the site in the event of an earthquake, yet it also has the ability to facilitate an everyday use through a connection between the 3 sites.

The utilization of rail track infrastructure is crucial in developing enough space for the site to function to cope with the shear amount of people who could potentially inundate the site. The extension is engineered to withstand the stresses associated with earthquakes and crowd numbers, whilst sitting atop of a somewhat unutilized space of above-ground rail tracks (something very uncommon within Tokyo). If necessary it is possible for people to travel along the existing rail tracks and meet up with the station extension, making their way back down to ground level.

162

ÂŹOne key problem with this aspect of the synthesis design was that it regressed back into the earlier design scenario test outcomes and did not look at how the design fitted within the larger system. This design fits within the synthesis approach, yet it works against what the body of research has been directed towards: a system that does not rely on one sole design/site to facilitate disaster mitigation. Thus, this design, if it were to be feasible would need to locate itself within a wider system of large centralized wayfinding towers, potentially changing the way in which Tokyoâ&#x20AC;&#x2122;s skyline is currently developed.

wayfinding routes re-evaluation

Wayfinding has been a common theme within the research as a tool for mitigation of such complex problems facing the city. This wayfinding design acts to connect initial primary evacuation sites (final phase of synthesis) together through a streetscape insertion, directing people along a designated route to travel along is during/following the event. This design connects the evacuation sites together through a usage of existing main roads and implicently highlights where the route lies, something which is not present on site at the moment (referenced through figure 0.1). One of the biggest problems that is present on site currently, is a lack of clear direction and signage stating where these already in place routes occur. In many wards throughout the city there is no clear common signage that is present, rather an eclectic mix of wayfinding beacons that do attract the attention of passers-by (within an everyday setting, let alone a disaster setting). Through multiple discussions I had with people living within Sumida-ku whilst on site, I was shocked to find that almost all did not know what procedures and services were available in the event of an earthquake, yet all were well aware of the inherent risks associated with living in the area. This design aims to connect users with these routes and establish a greater understanding of the connected system which links existing and newly reclaimed evacuation sites together.

re-evaluation A re-evaluation of the wayfinding markers documented in design scenario 0.1 (wayfinding) is necessary to build on what was learnt in the previous tests. These markers do not establish a connection with the users due to their lack of heirachy within the streetscape. This design uses the streetscape as the wayfinding marker, clearly showing through a blue line what is the route to follow in the event of a major disaster.

The hierarchy within the streetscapes of Tokyo is a challenge for this wayfinding device as the environment is so cluttered and intense, many elements blend into their surrounds or become paired back because of the shear amount of advertising, building densities, heights, narrowness etc. Building on the previous examples in figure 0.2, signage is not a feasible option within Tokyo, as it must compete with the advertising and other signage which already sits around it. Rather, a material change on the road can grab the attention of people, as such large gestures do not occur within the streetscape. Figure 0.3 attempted to work with the idea of difference to grab the attention of users, through a vegetation system, the scale was what let this test down in design scenario 0.1, as it would not make enough of an impression in the event of an earthquake. ie. if buildings were falling down around you, would you follow a small scale water purification tool to safety? This design uses heirachy and scale to grab the attention of users, connecting the existing evacuation sites and parks together with a new range of reclaimed sites.

At a later stage temporary infrastructure such as market stalls and moveable planters can be removed, making way for tents to be erected and facilitate a temporary camping site in the time following the disaster.

This is the final element of the synthesis design, linking in together the station extension, wayfinding route and reclaimed sites. The chronological order of the synthesis should be read in an opposite fashion to the way it has been layed out within this document ie. local reclaimed site, wayfinding device and finally the station yet because of the way in which the 9th scenario was developed, it was the most clear way to lay out the entire synthesis. The reclaimed sites are a development from the initial design scenario tests undertaken in scenario ¬0.2, 0.3 (evacuation parks) and 0.5 (land reclamation test). The evidence which I gathered through these tests will be developed through this final stage of the synthesis design. ¬

precedents Within this research examples of the Tokyo governmentâ&#x20AC;&#x2122;s roll-out of local parks and larger evacuation sites has been discussed and analysis of these sites undertaken. These serve as an anti-precedent for this research, including for this final design of the synthesis scenario. There are many problems associated with these sites and by beginning to question their function(s), form and locations, new development of similar sites can be undertaken through the design work; learning from what is already in place and establishing new functional spaces which respond their surrounds and the people who use them.

The mixed use space is similar to the Collingwood Peoples Market in Melbourne, having temporary food stalls, bars and shops occupy space which would almost always be turned into a carpark within Tokyo. The relatively new occurrence is something very foreign to Japan and has had great success in engaging people with these under utilized spaces. This precedent has been used within this final scenario as a reference of how a potential market and mixed use space can occur within Tokyo. The scenario looks at occupying the newly reclaimed sites with food carts and stalls on a temporary basis, engaging the local community with these newly formed local evacuation sites.

mori corporation

Mori Corporation sectional perspective for shopping centre

The Mori Building Corporation is a large Japanese company which is developing the cities in Japan by building large shopping and apartment complexes. The company has plans for a similar style approach to that of this final scenario: by building vertically, you can keep a small footprint. Thus, with a small footprint there is the opportunity to develop open space around the footprint. This is a key idea within this synthesis test, as local wayfinding beacons are established through the removal of some particular blocks and the instatement of towers, which then form smaller localized wayfinding beacons. The precedent is a much larger scale solution to the issues tackled within this research, yet the key principles are of a similar trajectory. The parks which are developed by the Mori Corporation lack context and any real functionality, much the same as the other park systems which are dotted around Tokyo. Through this scenario the similar application of ideas is evident, yet it does not forgo context or connection with the people who will use the space.

context Within this site it is common to see historical leather and craft industries still dotted throughout the neighbourhoods. The small-scale factories usually are double storey, with the working area on the ground level, whilst the living quarters are above. This occurrence was something to consider through this design, giving the potential for these small-scale factories and shops to develop weekly markets within the new sites, utilizing the common space and enriching the surrounding areas. Going back to some of the findings made on site following the visit to Japan (page 44), provided an insight into what potentially could work within these spaces and also what was not worth investing the time into. Local industries play a large role within these communities and establishing pride within the area will only be beneficial to these new public open spaces. By enriching the community, resilience is formed, creating stronger communities which are better equipped to deal with volatile situations such as earthquakes within this city.

plan The sites location is determined by points of interest within local neighbourhoods. The towers are determined by a 400m radius, this radius is determined by a reasonable walking distance covered by an elderly person who lives within the area. These points of interest within the blocks are maintained and the rest the block removed. By maintaining these community nodal points, everyday connections can continue to be made with the sites; when dealing with these sites on an everyday or regular basis, a clear understanding of the sites importance within the city as an local evacuation site is registered. Establishing these connections will aid in saving lives in the event of an earthquake as those who have established these connections with the sites will know exactly where to go. The footprints of these buildings will remain and an extrusion made vertically to gain the height necessary to be seen within each 400m radius. It is essential that points of interest are maintained within the buildings, cross programmed with the site and the residential tower which will now sit above it. On this site, a post office is a clear nodal point within the community, thus the footprint will remain and a tower extruded from this.

By having new visual beacon towers in place within each 400m radius this will form a vertical wayfinding device along the evacuation routes. Once a point to point rhythm can be established along these routes to each local park, the connection can be made onwards to the Tokyo Skytree or other central vertical wayfinding beacons around the city.

The removal of particular blocks on site will be a questionable task for anyone who may have to have their homes removed in the process of forming these spaces. All people moved on from their homes will have the opportunity to live within the residential towers on site and the height of these buildings will be determined by the height of the surrounding context. The building must be able to be seen within the 400m radius as this will form a crucial vertical wayfinding beacon within every part of the site.

Employing such tehcnologies within the new reclaimed site towers will not guarantee their survival, yet will provide some amount of strengthening and accountability.

sites These newly formed sites will use existing context to shape the designs of each open space, determined by elements such as existing footprints, proximities, roof lines, materiality, services, vegetation and commercial enterprises. The sites primary function is that of an emergency use which can facilitate a shift in program and system to help people escape from effected areas. It is also crucial that these sites do have an everyday use, which engages users and connects them with their local evacuation site. Previous work undertaken in scenario 0.2, 0.3 and 0.6 developed to the final sites by questioning the potential numbers and sizes necessary to facilitate camping on site, what essential infrastructure is needed as well as what timeframes and crossprogrammed designs could contribute to these sites.

reflection system - synthesis A systematic approach is by far the best way to begin to address complex issues such as the ones faced within this research. The synthesis approach looked at a range of different designs developed from previous design scenarios; question how they could work together as a system and begin to solve some crucial problems facing this site. Initially at the start of the research the design scenarios were quite independent and very distant from one another. It was only after selection and cross-programming results that it became apparent that a range of scenarios working together could begin to address these points. The synthesis approach solves some issues facing the site but many still remain. There is no solve-all solution for a complex problem such as this one. Looking back at the synthesis precedent (currently employed methods in Tokyo) the research has proven that there are better ways to design potential spaces and have greater effect on the people around them. The feasibility of the entire design approach may have been problematic, yet the ideas surrounding them are valuable when critiquing current techniques and refinement of employed ideas.

individual parts - synthesis Wayfinding Device The wayfinding device as a design from scenario 0.1 (wayfinding) and 0.6 (vending machine) was a progression that didn’t change in terms of application or aesthetics. Rather it connected and changed considerably to relate 2 other phases of the synthesis together. Developing a defined and clear route is vital within this situation. An everyday usage for the routes has been unpacked through the conclusion yet projection for the project could be development of such areas.

Station Extension Utilization of such iconic infrastructure in the context of the research is a completely viable option for mitigation, the problem lies in the fact that it is one single tower. By utilizing this sole piece of infrastructure there is too much emphasis on the one site, not diversifying risk and contributing to a ‘stacked system’. What is necessary to be unpacked in the projection is how a whole series of different Tokyo Skytree Towers would need to be designed if this scenario was to be completely aligned with the overall research framework. This was the least successful element of the synthesis because of the need for multiple versions around the city, potential issues surrounding visibility and connection on the ground plane.¬¬

Land Reclamation The design interrogates difficult situations within the city, occurring already in some parts of the site and wider city (government reclamation). The scenario is aligned with current practices; mainly the Mori Corporation but attempts to provide another level of detail with the sites, as well as providing an important disaster function. The scenario questions different phases of a potential event, also developing everyday programs and systems which can enrich the spaces. This was the most successful of the 3 tests and development element of the synthesis. ¬

RESEARCH conclusion Answers to the questions asked in the introduction of this document:

Tokyo is potentially going to be hit by a major earthquake within the next 4 years. This is a massive problem, as the city is largely unprepared to deal with such events and the scale of the city makes the prospect of a major earthquake a frightening though. The site chosen, Sumida-ku is the most dangerous area in terms of earthquake damage in Tokyo. Sumida-ku is the most vulnerable area in Tokyo, because of the density, susceptibility of the area (liquefaction), housing stock and shear size of population who live within this site. A range of different scenario-based mitigation designs have been developed within this research, providing techniques that could be employed at different times and scales. Currently a system is put in place that relies on local evacuation parks and larger secondary sites for people to flee to in the event of a disaster.

The scenarios have widely developed designs based on current conditions on site, understanding then re-designing what is employed, rather than designing something completely new to the site and adding to the already chaotic nature of the streetscapes. By â&#x20AC;&#x2DC;plugging-inâ&#x20AC;&#x2122; to the existing conditions you can work with the current conditions and create successful outcomes easier. The research undertaken in this document has been developed as range of different scenario-based designs, that set to mitigate the effects of a potential earthquake within the city of Tokyo. The scenario-based designs, critique currently employed methods of mitigation within the city, developing new, altered and redesigned methods/ designs, building on these examples and attempting to better mitigate potential problems faced within an earthquake time phase. The role of these designs is to primarily function within a disaster setting, but it is crucial that they also provide a day-to-day use, adding to the everyday life of the users who live within the city. After visiting Tokyo last year, the energy and shear number of people, the potential issues surrounding the city and the embedded resilience of the population, provided an inspiration for development of previous work undertaken in tsunami effected areas of Tohoku. This coupled with a new found interest in post-disaster design, provided a stepping-stone to develop my interests further and begin to question future potential disasters within a country that has been frequently affected by disasters throughout history. With an opportunity to visit Tokyo again with a travelling studio from Melbourne 193

University, the decision was made to begin working on this research for the Masters of Landscape Architecture 2013. The research is an accumulation of scenarios undertaken both before and after visiting the site, with successful iterations being chosen and developed into the final synthesis scenario. The research has developed a number of individual scenario-based designs that respond to the changing conditions of an earthquake within a pre, during or post phase of a potential disaster. A process of iteration was employed, developing a wide range of scenario-based designs. Through the production and evaluation of the iterations, an understanding of the notion of the ‘stacked system’ became apparent. That being: the sum of the parts is greater than the whole. By utilizing these ideals and applying the methodology of numerous designs, working together, the complex issues facing the city can begin to be interrogated properly, which sets to frame the scenario and research approach of the project. Through this approach the final synthesis design was realized after an evaluation of the previous design test scenarios was undertaken. Current practices of disaster mitigation in Tokyo rely on small-scale local evacuation sites, followed by secondary larger evacuation zones to flee to. The problem facing many of these sites within the city is that people largely do not know or acknowledge the location of these local and larger sites, creating potential problems in the event of an earthquake. Zooming out, larger problems exist within the city that has one of the smallest amounts of green space per person, anywhere in the world. This fact, along with current trends where by people widely do not engage with green space that is within the city, due to working. Investing time in developing your career is considered much more valuable than engaging with this type of space. This research body aims to limit these occurrences, instating new urban green spaces and frameworks and connecting users with these sites, through everyday interaction and connection. Once a connection is made with these sites, an understanding of the importance of them within a disaster becomes apparent. These sites can limit lives lost following an event, as people recognize they are comparatively safer points of evacuation than the buildings they occupy. Tokyo is within a constant state of contrast. Be it traditional versus modern or that it is considered one of the safest cities in the world, yet lays at the potential peril of an earthquake. The objective of this research was to develop a range of methods, questioning current practices of mitigation and developing multi-programmed sites. Through the design scenario iterations this has been unpacked, evaluated and developed further. The framework set in place for this research uses the iterations as location points with the site, situating themselves either at pre, during or post phases of the disaster. The success is determined by the criteria evaluation diagram and selected iterations chosen to be developed further through cross-programming or synthesis. The approach of tackling multiple designs at multiple scales is something, which is currently undertaken as a mitigation method within the city, although not as successful as potentially necessary. The final synthesis scenario attempts to address these issues by using previously developed methods and scenarios and pairing them together to work within a system of mitigation. By instilling everyday connections with newly formed local evacuation sites, followed by a 400m connection to further sites (wayfinding device) and finally on to a final-stage central meeting point, the synthesis now sets to act as the ‘stacked system’. One key gap that has emerged from this research is how you could justify the removal of resident’s homes to be turned into newly formed localized evacuation zones? The design was developed through a series of different iterations that began to respond to the existing conditions of the urban fabric surrounding the site, as well as drawing out specific references from the removed fabric, which could then be reimagined on a new evacuation site. By referencing what was once on site, users to these new sites can begin to make connections with the space, ultimately understanding the valuable role these new spaces perform within the city, as well as altering the urban fabric within the wider context of the city towards a higher green-space density. Another key problem faced within the research was how do you begin to establish connection or knowledge of the designs with users? How do you get people to use them? Within the different design tests key references have been made to these existing conditions on their respective sites. By developing or re-designing what is already in place, you are not adding another level of intensity to the already chaotic streets of the city. Rather, a refinement of what is already in place and potentially already understood by the wider public. It is only through regular interaction(s) that users will begin to acknowledge and understand the system of mitigation that this research proposes. Much of the current state of parks and open space within Tokyo is in a poor state, thus people do not use the sites as would be the case if they were in Australia or Europe. Creating functional spaces with a range of different programs will bring people to use them (see 246 COMMON example on page 175). ¬ Another key issue facing these sites, is the instatement of new towers which are set to act as local wayfinding beacons. Due to the incredible density of Tokyo, especially within the site of Sumida-ku, the density of buildings may be so great, that in certain areas the tower is not visible within the 400m radius. By using already established sites such as post offices, shrines, police boxes etc. there is a greater chance of a clear understanding of where people are able to flee to, through remembering connections with these spaces/programs. Failures of this research are centred around the final synthesis design of the final evacuation site, developed at the 194

base of the Tokyo Skytree Tower. This is due to the fact that throughout the research the general trajectory of the work has been developed around the multi-site/design system. As compared to current practices which rely on single-use, final-solution approaches which are very common within the city at the moment. This design acts as one single solution, designing for one site that acts as a final destination for thousands of people. By establishing these single-entity designs, the opportunity for these sites to fail becomes apparent, without other potential solutions been evaluated. The design scenario was then altered slightly to begin to question the surrounding streets and buildings as overflow space, as well as questioning how different sites could be imagined, changing the skyline of Tokyo drastically. This research does not set out to solve all issues surrounding the complex problems potentially faced by the city of Tokyo in the near future. The research has been developed as a tool for rethinking and redesigning what is already in place, aiming to not solve the problems, rather mitigate or limit some of the problems. Going to Japan on a field trip was a turning point for the research when suddenly site specificity became apparent as ideas formed in Melbourne were quickly quashed with true understandings of site. This changed the trajectory of the research to now consider a range of time phases together, forcing multi programming into the designs and everyday outcomes of the scenarios. One crucial discovery within the research, was the use of the criteria evaluation diagram. The diagram was developed as a tool for judging the success and failure of each design scenario. In trying to formulate a criteria for evaluation, different questions were asked attributing to different points. This gave a numerical result, but had no real meaning with such a value. After the diagram was developed further, different criteria points could be judged visually against each other, giving a representation to the overall rating of a particular scenario. The criteria evaluation tool proved to be a valuable diagram in explaining many of the decisions made within the research and could be developed further into my own personal evaluation tool within my career. Many problems and gaps have emerged from the scenarios but the opportunity for different ideas and ways of thinking about such complex issues, far outweighs the feasibility or actual potential of some of the design scenarios. Tokyo is always within a constant state of change. Constantly demolishing, rebuilding then demolishing again. This cultural practice comes from the ideas regarding disaster and resilience, something that is inherently Japanese. The research acts on this and develops a wide range of potential scenarios to addressing select issues on site. The scenarios do not aim to solve every issue faced within a major disaster in Tokyo, rather a selection of critical needs. Acting on these issues is a matter of priority for the Tokyo Metropolitan Government, as the potential destruction of this amazing city could be a very real situation. Lessons can be learnt from Kobe, Christchurch and Haiti must be addressed on this site, if it stands any chance of pre-empting a major earthquake within the city.

follie 0.2: forces on landscape This follie explored the idea that a particular site or landscape could adapt to a series of forces, which were imparted on it. The model was made such that the wooden skewers were connected to the stocking (landscape/site) as well as been connected at the base of the model via some wire. The wire could be manipulated and this in turn would make a magnified manipulation on the unfixed skewers and stocking above it. These changes were documented on film and the stills collected showing some of the adaptations for which the site/landscape could go through. 202

follie 0.3: landscape/infrastrucuture This follie explored the concept of landscape and infrastructure and the outcomes, which could be produced given a certain element, was given priority over the other. The expandable foam represented the landscape whilst other elements represented infrastructure. This follie was one of the more successful given the unknown nature of the outcome when using the expandable foam. The diagram above attempts to show the particular outcomes given the priorities given to each element and the connections which were a result of the tests. 203
