Review: Big Data

The following was submitted to the University of Pennsylvania's School of Design as part of the Systems Thinking elective in Fall 2013.
"We’re going to find ourselves in the not too distant future swimming in sensors and drowning in data." (1)
For Viktor Mayer-Schönberger and Kenneth Cukier, authors of Big Data: A Revolution That Will TransformHow We Live, Work, and Think, the “revolution” that is currently shaping the contemporary world has the potential to create fundamental transformations in the way in which society operates, on a par with the introduction of the Guttenberg Printing Press in 1450. They point to the fact that "In less than a person's life span, the flow of information has changed from a trickle to a torrent" (2) and that throughout history people have always “opted for more information flows rather than less." (3) The book sets out to describe big data, (4) defined as “the ability of society to harness information in novel ways to produce useful insights or goods and services of significant value", (5) as a theoretical and practical construct that will continue, and greatly accelerate, this trend.

Big Data: A Revolution That Will Transform How We
Live, Work, and Think (Houghton Mifflin Harcourt, 2013)

The co-authors, an academic and a journalist, share common research interests in areas surrounding Internet governance and technology, recurring themes throughout Big Data. Considerable time is spent dealing with the Implications, Risks and Control (Chapters 7, 8 and 9 respectively) of big data, which is perhaps a testament to the fact that Viktor Mayer-Schönberger is the Professor of Internet Governance and Regulation at the University of Oxford, and in 1986 he founded Ikarus Software, a company focused on data security. (6) With other interests surrounding innovation and intellectual property rights (both touched upon in Big Data), Kenneth Cukier is currently the Data Editor of The Economist, having previously been the paper's technology correspondent. (7)

Setting out their intentions for the book early on, the co-authors intend to “explain where we are, trace how we got here, and offer an urgently needed guide to the benefits and dangers that lie ahead." (8) Judged by these criteria the book is fairly successful, providing a comprehensive yet accessible overview to both the benefits and the risks of big data. It should be noted that early on in the book they describe themselves “not so much big data's evangelists, but merely its messengers”, however at times Big Data does come across as evangelical in its praise of big data’s virtues. (9) Whilst this is tempered by discussions about the risks associated with its adoption, which widens the discussion beyond issues of privacy, the tone nevertheless falls firmly on the side that big data is good and that it is here to stay. (10) When asked in an interview about the likely trajectory of big data over the next five years Cukier predicted that it will unfold in much the same way as the Internet, with widespread adoption of big data “around all corners of society”. (11) Big data’s ‘breakthrough moment’ may already have happened, with Cukier drawing comparisons between “the birth of the Web at the Netscape IPO” (1995) and the Facebook IPO in 2012: “It is a $67 billion company with very small revenues and small earnings and all the value of its share is in the promise of what its data holds." (12)

Datafying, then digitizing, big data

The term “big data” emerged during the 2000s, with an ‘explosion’ of data in sciences such as astronomy and genomics; it has since migrated across disciplinary boundaries “to all areas of human endeavour." (13) Today big data “refers to things one can do at a large scale that cannot be done at a smaller one, to extract new insights or create new forms of value, in ways that change markets, organizations, the relationship between citizens and governments, and more." (14) This relies on a dramatic increase in not only the amount of quantitative information available but also the expertise and the tools to properly utilise it. However, Mayer-Schönberger and Cukier go to great lengths throughout the book to explain that whilst “changes in technology have been a critical factor making it [big data] possible, something more important changed too, something subtle."(15) This subtle shift is a change in mind set about data itself and how it can be used; this is the “revolution” Mayer-Schönberger and Cukier are referring to, not the machines. (16) An initial quantitative change (technology) has produced a qualitative change, comparable to the difference between a photograph and a movie: “by changing the amount, we change the essence." (17) Furthermore, today data is no longer “regarded as static or stale, whose usefulness was finished once the purpose for which it was collected was achieved” but is instead recognised as “a raw material of business, a vital economic input, used to create a new form of economic value." (18) To put it another way data is “the oil of the information economy" (19) but whereas oil can only be used once, data can be used again and again.
That big data is often conflated with issues surrounding technology is not surprising when you consider that “The amount of stored information grows four times faster than the world economy” and that this process is only speeding up with further technological advancement, to the point where “Everyone is whiplashed by the changes." (20) This conflation is further aggravated by the fact that big data is “described as part of the branch of computer science called artificial intelligence, and more specifically, an area called machine learning … [but] Big data is not about trying to ‘teach’ a computer to ‘think’ like humans." (21) Regardless of this it is difficult not to argue that technology, and particularly digitization, has not had an important role to play, even if “it is important to keep them separate." (22)

Mayer-Schönberger and Cukier trace the building blocks of big data back far beyond the realm of the digital age. (23) Ancient civilizations attempted to collect census data for entire empires but the difficulty in the analogue world was that this was both costly and time consuming—the intrinsic value of large datasets was never in question. The work of Matthew Fontaine Maury in the 1800s is used to demonstrate “the degree to which the use of data predates digitization”. (24) Alongside his dozen “computers”, Maury revisited old logs to extract and tabulate valuable information on temperature, wind speed, and time, which had been discarded, and from it draw new navigational charts. (25) There are then two prerequisites to ‘datafication’: having the right set of tools; and a desire to quantify and to record. (26)

Whilst mathematics gave new meaning to data in centuries past, the shift from information no longer being stored in atoms but in bit has resulted in much larger transformational effects. (27) However, “The act of digitization—turning analogue information into computer readable format—by itself does not datafy." (28) The differences between datafying and digitizing are epitomized, for the co-authors, in the differences between Google’s Book Project and Amazon’s Kindle, surmising that: "Perhaps it is not unjust to say that, at least for now, Amazon understands the value of digitizing content, while Google understands the value of datafying it." (29)

Valuing more, messy, correlation

At the core of the principles underlying big data are three major, interconnected, shifts in mind set, each serving to reinforce the others position. The first is the ability to analyse vast amounts of data, without the restrictions of smaller sample sizes. Second, there is a “willingness to embrace data's real-world messiness rather than privilege exactitude.” Finally, causality is replaced by correlation as the driving force. (30) 

Historically, we have “relied on to the barest minimum” when collecting information; this was (and still is) “a form of unconscious self-censorship … an artificial constraint imposed by the technology at the time." (31) Today the ‘codified practice of stunting’ is no longer necessary because "The shortcomings in counting and tabulating no longer exist to the same extent." (32) This data is also increasingly temporal but its’ chronological contingency is less relevant because newer data is always being gathered by passive measures, from GPS to Twitter, replacing the outmoded data set. (33) Of course all of this requires "ample processing and storage power and cutting-edge tools to analyze it” but with these now accessible the cost of comprehensive data collection has fallen dramatically. (34) Furthermore, just as the Lytro Camera “records the entire light field instead of a 2D image” enabling the viewer to refocus pictures after they are taken, data can be revisited for entirely new reasons and purposes. (35)

The issues of dependency, messiness and exactitude are explored through descriptions of various translations devices that have been developed. It is argued that previous failures at translation software can be accounted to their design being based on a predilection with exactitude, an obsession which is “an artefact of the information-deprived analogue era." (36) To discard, or at least lessen, the importance of exactitude relies on embracing that we are never able to collect perfect information; therefore “as long as it is imperfect, messiness is a practical reality we must deal with." (37) Previous statisticians relied on imperfect information in the form of sampling, in the hope that the accuracy would make up for the limitations of the sample size, but today we can work with much larger samples that seem to iron out any errors produced by inexactitude. (38)

Having embraced having more, messy data, Mayer-Schönberger and Cukier present a new “pragmatic approach” wherein with big data “Knowing what, not why, is good enough." (39) The pursuit of one single version of the truth is seen as a distraction, things are far “more malleable than we may admit”, (40) and as such causation is less important than correlation. The work of Daniel Kahneman is used as a demonstration of the human obsession with causalities, painting causation as a fast-thinking activity that jumps to conclusions far too quickly. (41) Whilst, correlation does not bring about certainty, only probability, when “a correlation is strong, the likelihood of a link is high." (42) The advent of machines capable of more powerful computations means that the limits of traditional linear correlation can be discarded in favour of more complexity, identifying non-linear relationships among data. (43)

If these three mind sets are fully adopted then, "in the age of big data, all data will be regarded as valuable, in and of itself." (44) This is because information is a “non-rivalrous” good, that doesn’t wear out and as such “The crux of data's worth is its seemingly unlimited potential for resuse: its option value." (45) In order to unleash the option value of data three methods are presented:  basic reuse; merging datasets; and finding "twofers." (46) Wilst each of these strategies is relatively straight forward, it is when they are applied to “data exhaust”—the by-product of people’s actions and movements in the real and digital world—that the greatest option value can be obtained.. (47) As seen by the valuation placed on Facebook, data as an intangible asset is now as valuable to a company as its brand, talent and strategy. (48)

Implications and controlling the risks

Currently companies can be differentiated into three broad categories based upon the data, the skills, and the ideas they offer, although some, such as Google, benefit from "vertical integration in the big-data value chain, where it occupies all three positions at once." (49) According to Mayer-Schönberger and Cukier the skills to succeed in this new big data workplace are shifting and “Today's pioneers of big data often come from disparate backgrounds and cross-apply their data skills in a wide variety of areas." (50) The breaking down of traditional silos and the cross-fertilisation of ideas amongst disciplines is not a trait unique to big data however the co-authors go one step further when discussing the possible demise of the expert, due to big data practices. They point to a change in the way in which knowledge itself is valued, and that expertise, like exactitude, is only appropriate for “a small-data world where one never has enough information, or the right information, and thus has to rely on intuition and experience to guide one's way." (51) In this new landscape the middle of an industry will be squeezed, so that firms will be either very large or small and nimble, recasting traditional sectors as diverse as city planning, manufacturing, pharmaceuticals and financial services. (52)

If these are the wider implications for a new big data world, there are three categories of risk that we will all be faced with: issues of privacy, propensity and the fetishization of data. (53) This is the dark side of big data; it “allows for more surveillance of our lives while it makes some of the legal means for protecting privacy largely obsolete … [it] renders ineffective the core technical methods of preserving anonymity ... [and] there is a real risk that the benefits of big data will lure people into applying the techniques where they don't perfectly fit". (54) The three core strategies of individual notice and consent, opting out, and anonymization, are no longer effective in the big data age and as such Mayer-Schönberger and Cukier  "envision a very different privacy framework for the big-data age" (55) wherein there is “a regulatory shift from privacy by consent to privacy through accountability" (56) They are keen to stress the importance of maintaining individual responsibility within these new systems and that the more we attempt to reduce risk in society by relying on “data-driven interventions” the more we devalue that responsibility. (57) They propose a new caste of professionals, big data auditors or Algorithmists, who “would take a vow of impartiality and confidentiality", as a means to ensure human agency remains amid computer driven predictions. (58)

Now

Each of the measures set out in the book are designed to put big data in its place, as nothing more than a tool and a resource. (59) Mayer-Schönberger and Cukier talk about a new world that is taking shape now, “already sketched in faint traces that are discernible to those with the technology to make them apparent." (60) To them this is not a world built on "ice-cold … algorithms and automatons” rather there is “an essential role for people, with all our foibles, misperceptions and mistakes, since these traits walk hand in hand with human creativity, instinct, and genius." (61) The question then is if big data is happening all around us, how is it shaping our lives beyond the invisible infrastructures and business systems with which the book is primarily concerned and for whom the co-authors view as its most advanced users. (62)

Aside from fleeting references to sensors being fixed to bridges and buildings, (63) to grey infrastructures, such as roads and vehicle tracking, (64) or manhole inspections and illegal conversions in New York City (65) (this is not to say that these are not important activities) there is little tangible evidence presented in Big Data with which a built environment professional can grapple.  This seems odd given the assertion that the new mental outlook of big data “may penetrate all areas of life” so that the world is seen as information, with “oceans of data that can be explored at ever greater breadth and depth”, and that this in turn “offers us a perspective on reality that we did not have before.” (66) It is seems curious then that the book is lacking in any references to the smart city concept, described by Adam Greenfield as either “urban-scale environments designed from the ground up with information-processing capabilities embedded in the objects, surfaces, spaces and interactions that between them comprise everyday life” (67) or the broader “drive to retrofit networked information technologies into existing urban places.” (68)

Perhaps there is something to be drawn from the examples of European car manufacturers given in Big Data (69) or the business model of Rolls-Royce, (70) which could possibly be replicated by companies specialising in building components or systems, such as façade packages. Would this lead to large scale transformation of society? Probably not. It may alter procurement or operation and maintenance procedures but as for the wider public, they would likely see little difference. These ‘solutions’ have more to with the enthusiasm over the Internet of Things (IoT) (71) or the ’smart’ offerings of IBM, Cisco and Siemens, that Greenfield calls into question, than a revolution. (72)

If smart cities are ‘missing’ it is perhaps not surprising that there is also no mention of Building Information Modelling (BIM). (73) As recently as June 2013, The Bartlett Faculty of the Built Environment at University College London hosted a conference on big data and BIM. At the conference, Andrew Hudson-Smith, Director of the Centre for Advanced Spatial Analysis at The Bartlett, stated that big data is the medium through which to join Building Information Modelling (BIM), Geographic Information Systems (GIS), Citizen Science and the Internet of Things together. (74)

As successful as Big Data is in painting a picture of the new big data age, when it comes to the built environment the brush is broad and the detail lacking. Those concerned with how big data is shaping the built environment must instead turn to others.

Next

In a trilogy of papers, published between 2011 and 2013, Nick Dunn re-imagines digital space as a new terrain within which architects and urban planners can operate. Whilst this in itself is not a new approach, finding precedent in Archigram’s Plug-In City (1964) or Instant City (1968-70) and Archizoom’s No-Stop City (1969), or more recently UNStudio’s Time-based Urbanism (1997), MVRDV’s Datatown, Sector Waste (1999), and Asymptote’s New York Stock Exchange (1999), Dunn brings the discussion into the physical world. He describes the overlaying of digital technologies upon extant physical situations as a “multi-layered landscape”, (75) noting that “the city as we understood it … has now changed." (76) Whilst the emergence of new city models predates the digital age, it is clear that “The transformation of the physical landscape towards an increasingly incoherent set of urban conditions and the corresponding flows of endless data into an apparently infinite and united system has implications for what we might consider to be public domain." (77)

For example, the Sensity (2004-09) project by Stanza provides the public with “access to invisible but important qualities of the city” and “offer[s] a rich platform across which we [might] better understand our urban landscape”. (78) It is part of a much longer lineage, which includes the Nolli Map of Rome (1784), in providing new representations of public and private domain. Mapping exercises such as Stanzas are important to Dunn because they describe “the ecological mutuality between digital and physical landscapes, especially with regard to social behaviour and patterns." (79) Furthermore he is critical of the position that posits “digital networks and physical conditions are distinct, as opposed to integrative” and challenges designers to “to develop greater instrumentality that affords thick descriptions of scenarios and enables us to develop appropriate design strategies and responses” to deliver these multi-layered landscapes. (80)

With or without architects a new “intelligent terrain” is emerging, based on a framework of “community-led digital platforms that are easily accessible, robust and responsive to their citizens." (81) Projects such as Open Raleigh (82) or Data Driven Detroit, which has produced the D3 Toolbox, “envisioned [supporting] communities with the data necessary for them to take action in their neighbourhoods." (83) Large scale data collection has always been the purview of the state, (84) and whilst private enterprise may now be collecting their own big data, “Recently the idea has gained prominence that the best way to extract value of government data is to give the private sector and society in general access to try." (85) The future production of space and place will be dependent upon new interfaces, with built in feedback mechanisms, that enable the general public to not simply read a dataset but to get involved in it; this new “connective tissue, i.e. our sociospatial relations and experiences [and will] result in a useful territory from which to develop responsive tactics to urban space from places that are both socially constructed and personally perceived." (86)

It has not been possible to go into the various claims that Adam Greenfield makes against the smart city, however central to his argument is that the ubiquitous off-the-shelf products being sold as ‘smart cities’ are designed for “abstract, featureless terrain” and not “actual places”. (87) He is calling for work which is “technically sophisticated and [can] take every advantage offered us by emergent ways of doing and making." (88) I would posit that it is the “realistic hybrid of top-down and bottom-up systems” described by Dunn that Greenfield is arguing for, “rather than the illusion of an always on, always ready, always connected, networked society" (89) (a description that seems to aptly fit the new world traced by Mayer-Schönberger and Cukier).

Today then “our cities are already densely and intimately linked with one another, bound together by their own citizens in a constant and mutually reinforcing traffic in atoms and bits." (90) Finally, in the age of big data the scale of the city no longer matters, it is scale of the data that is important. (91) However, it is important to remember that “we are the network and [we are] the data”. (92)

Representation Versus Production

Architectural practitioners today are “expected to have a highly evolved set of design skills,” (1) employing a varied range of media to accurately communicate their ideas. Constructing the built environment requires a considerable investment in time, resources and ultimately finances and whilst “representation is an important aspect of any visual or design-based discipline” (2) the importance of accurate tools of representation in architectural practice is even greater. These tools of practice are judged on how readily they allow the architect “to repeatedly describe, explore, predict and evaluate different properties of the design at various stages prior to construction.” (3) There have never been so many tools at the disposal of those who wish to represent and shape the built environment as there are today, “each with the capacity to leap only previously imagined frontiers.” (4) A practicing architect today is able to use anything from ‘traditional’ methods like a simple sketch on pen and paper, through to emerging technologies like rapid prototyping, CNC milling machines, laser cutters, and powerful computational software in their practice.

Throughout history the practitioner’s tools have served two purposes, (i) as creative representation of an idea and (ii) technical production information of an architectural object. (5) The tools of representation have changed little over the past 500 years (6) but in the last 20–30 years there have been several developments that have dramatically changed the way in which architecture is practiced, with the most notable being CAD (computer aided design) and more recently BIM (building information modelling), which seemingly promises to “unlock new ways of working”. (7) Before the rise of the computer the process of architectural representation was achieved through using hand drawings and physical models, with the architectural drawing holding particular sway since the Renaissance. (8)

In the Renaissance the essential components of the architect’s formal training were perspective and drawing, or disegno. (9) Dalibor Vesely talks extensively about the advent of perspective during the Renaissance transforming the representation of the visible world. However because “we don’t live in a perspectival world” Vesely adds that whilst perspective “certainly does influence and can even dominate our way of life…its sway is never total.” (10) All methods of representation, perspective included, “offer no more than the possibility of seeing and experiencing the world in a particular way” (11) because they relied on reducing the complexities of the world. This process of reduction is perhaps best expressed in the development of Parti, popularised during the 19th century at the Ecole des Beaux-Arts, that reduced complex ideas into “abstract sketches that are loaded with architectural meaning and intent”. (12) The Beaux-Arts system also included the educational exercise of l’esquisse, in which students spent three months working on one design that had been frozen after just twelve hours of initial work and were then marked based on how closely they had stayed to the original concept. Even in the age of the computer the enticing powers of the architectural sketch remains, imbuing an ideal that “it should be possible to sketch the concept of a good building in less than ten seconds”. (13) These methods though, from the sketch to the rendered perspective (either produced by hand or with computer software), are representations of a creative idea, they do not represent the finished product because “what comes out is not always the same as what goes in.” (14) It is for this reason that there is a differentiation between drawings as creative representations and drawings as production information, distinguished by the type of information they convey.

Problems arise when it is assumed that “if architectural drawing can successfully represent a set of presumed virtues, then surely that same technique can be used to deliver those virtues back to the world.” (15) There is obviously a difference in type of information necessary to create an overall impression of the built environment, to ‘sell’ that project to clients, local planning departments or the public, and the technical information required to build that vision. Both types of drawing rely on graphic instructions, in the form of codes or conventions, which organise complex information precisely and accurately, it is not just the case that one drawing has a higher level of detail or more information than another. The conventions are interpreted as a series of codes that are introduced in education and developed through practice. No matter how good a particular three dimensional rendering may be (whether drawn by hand or using a computer) the chances are it will never be able to convey all of the information required to build that project; for example, the drawing may give an impression about materials but a single image won’t explain the technicalities of how these materials are assembled on site.

The drawings codes are assumed to be “transparent” however “evidence points to fundamental misunderstandings by nonarchitects of even ‘simple’ drawing codes, such as floor plans”. (16) Architectural practice is not alone in having developed an internalised language from a series of codes that forms a barrier for those not indoctrinated in these methods to understand them. (17) Particular difficulties arise when so many different professions are dependent on information from one another as in the built environment industry. Successful architectural practice makes the most productive use of the various different codes of representation available to them, using the most appropriate drawing (or model) to convey the required information, but they also realise that an architectural drawing is different to the architectural object it helps to create.

The Digital World

Before the computer was introduced into the design process a common site at architectural practices was that of rows of drawings boards and teams of draftsmen producing the range of drawings required to erect a building. Two dimensional, vector based drafting systems had been developed in the 1960s for commercial applications in the aerospace, electronic and automobile industries however it wasn’t until Autodesk launched their AutoCAD software for PCs in 1982 (18) that it slowly became more widely available in architectural practices (as PCs proliferated so did software like AutoCAD). Today the computer is ubiquitous in the design process but the codes and conventions employed are the same as those used when drawings were produced by hand—the computer screen is treated as a piece of paper and the mouse the technical drawing pen. This is an observation that causes Vesely to question “how the new electronic representations differ from the traditional ones; to what extent are they only more sophisticated tools, or do they rather represent something altogether different?” (19)

Regardless of whether or not the computer represents something different it has resulted in different work patterns within practice. The computer allows for smaller teams to produce the same information in less time than larger teams working with ‘traditional’ methods, thereby improving both productivity and accuracy. It is simpler to make changes, different options can be explored quickly and 3D packages allow projects to be interrogated from multiple viewpoints. However, the computer has also attracted criticism because “its immense power tricks its users (the designers) and viewers (potential clients) into believing that what is on the screen is what will be achieved on site” further emphasising the difficult relationship between representation and finished object. (20)

With increased computational power architects are now able to indulge in free form studies, a case of technical determinism, and pursue a new design paradigm of parametricism. (21) The technicalities of constructing these shapes still lags behind the virtual environments though, with the exception of rapid prototyping systems but these remain limited in size and application, and this divorce between virtual form and physical ‘buildability’ is a constant point of criticism of these methods. Despite the criticisms of free form studies the computer has enabled a new dialogue between architects and the process of building. With rapid prototyping architects are able to transfer information from the screen to physical models that are more open to interpretation from those not trained in the codes of architectural practice.  (22) Further benefits arise when you consider that CAD information can be shared with manufacturers of real components for the final building. Architects are able to exchange files directly with the manufacturers of prefabricated components, ranging from individual cladding panels to a SIP (structural insulated panel) system for an entire building.

A Double-Edged Sword

The latest development in the tools of architectural practice is BIM and it could be either “the harbinger of death or the salvation of architecture”. (23) BIM involves working on a three-dimensional model that is essentially a digital prototype of a physical building. It promises to improve design reliability, reduce design risk, reduce waste and enhance communication between different disciplines, amongst other expected benefits. (24) The model coordinates digital information about a project, with every component in the model tagged with data including product specifications, cost, and when it is scheduled to be installed on site. This model should contain information about the buildings entire life-cycle, from design through to procurement, construction, management and operation. It also forces design decisions about materials and construction methods (amongst others) to be made much earlier on in the process, if decisions aren’t made the model has to be made based on a series of assumptions.

It is however a complex piece of technology that requires “additional training and changes to a firm’s business process” and it is perhaps this that has contributed to the UK lagging behind other countries in adopting it. At present it is estimated that only ten percent of UK projects use BIM systems compared with sixty percent of project in the United States. (25) However, in the UK the technology is likely to be made compulsory for all public projects by 2016 (26) which means if architects are going to be involved in these projects in the future they are going to have to adopt BIM systems. (27) Ruth Reed, RIBA President, described the advent of BIM as a “complete game changer” (28) for the architectural profession and it is generally considered the future of building design.

As BIM effectively allows a test run of the entire building before anything is committed on site it has the potential for time to be introduced into architectural representation. The model means that the lines in the sand traditionally drawn between design, construction and operation of the built environment are eroded. It also has the potential to satisfy the criticisms Jeremy Till aims at current modes of communication, which freezes the built environment in one temporal condition, whereas BIM allows the building to be explored at different periods in time, albeit within the limitations of virtual environment previously considered. (29)

It is the multidisciplinary element of BIM which has the most potential to influence the design process, allowing for greater communication between the various different professions involved in creating the built environment. Information from different disciplines is fed into a single model which is then used to coordinate that information (from clash detection to construction phasing). Working with collaborative design information has been shown to produce a minimum saving of 5-10% and in an era where cost is one of the main drivers of design this alone is seen as reason enough to adopt BIM systems. (30) A fully integrated design process will not mean an end to the existing tools of architectural production however they will be challenged to work with this new tool.

Perhaps the largest barrier will be a shift from working in two dimensions, which architectural drawing in particular has relied on, and into a continual process of three dimensional communication, which at present is only achievable through time consuming physical models or computer renderings. Whilst BIM does allow for a level of creative representation its primary function is as a tool to aid the technical production of the built environment.

Beyond Drawing

The tools of practice considered here have centred on architectural drawings, produced both by hand and on computer, but there are obviously other types of information required to practice and to shape the built environment. These other tools range from schedules to specifications, project work flows to contracts and are of equal importance in spatial production but also include the vast array of techniques employed on site to build projects. There are arguments to suggest that even “negotiating a legal contract between an architect and a client is another ‘art’” (31) and as such is just as open to the creative processes of architects as a sketch.

It is though an obsession with image that dominates the discussion about the tools of architectural production, and of representing that image. As new tools emerge they will enable a transition from two-dimensional to three-dimensional ways of working as a new standard. These technologies could also bring about a closer relationship between the other forms of information required in production (the schedules, the specifications, etc) and the methods employed in constructing the final object. (32) Practitioners though should be wary of placing too much faith in one piece of technology or type of representation that can ultimately only predict outcomes based on previous experiences. Whilst there will never be a replacement for actual physical realisation, when the architectural object is embedded and exposed in its context, the better the tools available to practitioners the more informed the decisions they take can be and this is surely a positive thing.
