Digital Fabrication in Architecture, Engineering and Construction

Digital technologies are changing the relationship between design and construction: with computer models, CAD/CAM, and prototyping, designers can gain direct control of building and construction processes. The ability to digitally model designs, and thus to use those models directly in the context of production, creates a synthesis between design and construction in keeping with the tradition of the close relationship between design and craftsmanship, between the quality of the design and the rules of the craft. The evolution of the culture of design and construction is the underlying theme of this book. The aim is to discuss the direction that innovation is now taking, with a particular focus on today's cutting-edge architectures. The method addresses the ways in which different societies have dealt with the issues of their age regarding design and construction, the different contributions provided by various techniques, and with them the meanings expressed by the architecture. As building design using digital tools requires specific skills in the fabrication processes and in the languages used by information technology, the book also offers a practical guide to new methods and techniques of managing and controlling fabrication for AEC. A systematic analysis of new skills used in the design process presents an overview of opportunities for architects and engineers. By collecting information on significant projects and analyzing them, the book explores the technical and artistic potential of digital technology. The cases studied are the outcomes of groundbreaking projects which were able to give form and significance to technological research. They show that digital tools are not the exclusive prerogative of large firms but can also be adopted by teams working across small and medium-sized firms - firms which have been able to use informed research to link innovative design with the possibilities offered by digital fabrication in architecture.

Future Cities and Regions. Simulation, Scenario and Visioning, Governance and Scales

This guide for tomorrow's urban practitioner systematically explains fourteen best practices across three continents; it explores questions of broad interest for designing and planning the future of cities and regions. Key questions addressed are: Is simulation useful to explore the effects of different design, policy and planning strategies? Which approach will help manage the uncertainties of metropolitan areas both today and tomorrow ? What are the strengths and weaknesses of the different simulation practices for city leadership, public and private partnership, and citizen involvement? The book reviews computer models and media, socio-political initiatives, professional practices which help communicating the future effects of different design, political and planning strategies with a wide range of aims: from information, through consultation, towards active participation. These world best practices are considered according to four leading issues for urban and regional development, respectively Simulation, Scenario and Visioning, Government and Governance, and Scale. The book examines the approaches adopted technically and procedurally. The selected knowledge and the innovative tools used in each case study are among the most advanced and up-to-date in the professional and research fields. This volume successfully illustrates these innovative practices and methodologies in a straightforward and accessible wa

Constants in Future Cities and Regions

The paper resumes some of the conversations the authors had in three years of research, based on the review of best participatory planning practices worldwide. The case projects are selected and discussed with the protagonists across four leading issues: Simulation, Scenario and Visioning, Government and Governance, and Scale. The case-oriented discussion is a peculiarity of the book , contributing to give shape to future cities or regions. The aim is to build a critical thinking on how urban planning, policy and design issues are faced differently or similarly throughout every cases studied. The book include the description of computer models and media, socio-political experiments and professional practices which help communicating the future effects of different design, policy and planning strategies and schemes with a wide range of aims: from information, through consultation, towards active participation. The cases have confirmed that simulation tools can impact on local government and can drive new forms of "glocal" governance, shaping and implementing future plans and projects at different scale and time span. The following paragraphs will point at some of the constant thoughts the authors had around the selection and editing of the book's case studied and related issue

NEIGHBOURHOOD REGENERATION AT THE GRASSROOTS PARTICIPATION: INCUBATORS’ CO-CREATIVE PROCESS AND SYSTEM

Incubators of Public Spaces is a funded JPI Urban Europe project aiming to support the self-organisation of places, by enhancing the factors that motivate, encourage, and enable the urban actors to reach common understandings in order to coordinate their actions by reasoned argument, consensus, and cooperation rather than strategic thinking only. By catalysing citizens’ willingness to ‘do their bit’ for improving spaces, it provides the means to grow and care for places. The paper is organised into three main sections. The first section offers a theoretical underpinning on the roots of self-organisation and co-creation in urban interventions. After a brief introduction about project’s aims, the second section deals with the Incubators co-creative process and system. It describes the running of the scenario workshops, and provides an overview of the web platform and its inherent features. The third section presents the results of the application of the Incubators method in the regeneration of an Italian neighbourhood. It provides some general information about the area, and foresees a set of interventions for both built and open spaces. Conclusions offer early remarks concerning the on-going experimentation in Incubators

Teaching Construction in the Virtual University: the WINDS project

This paper introduces some of the Information Technology solutions adopted in Web based INtelligent Design Support (WINDS) to support education in A/E/C design. The WINDS project WINDS is an EC-funded project in the 5th Framework, Information Society Technologies programme, Flexible University key action. WINDS is divided into two actions: ·The research technology action is going to implement a learning environment integrating an intelligent tutoring system, a computer instruction management system and a set of co-operative supporting tools. ·The development action is going to build a large knowledge base supporting Architecture and Civil Engineering Design Courses and to experiment a comprehensive Virtual School of Architecture and Engineering Design. During the third year of the project, more than 400 students all over Europe will attend the Virtual School. During the next three years the WINDS project will span a total effort of about 150 man-years from 28 partners of 10 European countries. The missions of the WINDS project are: Advanced Methodologies in Design Education. WINDS drives a breakdown with conventional models in design education, i.e. classroom or distance education. WINDS implements a problem oriented knowledge transfer methodology following Roger Schank's Goal Based Scenario (GBS) pedagogical methodology. GBS encourages the learning of both skills and cases, and fosters creative problem solving. Multidisciplinary Design Education. Design requires creative synthesis and open-end problem definition at the intersection of several disciplines. WINDS experiments a valuable integration of multidisciplinary design knowledge and expertise to produce a high level standard of education. Innovative Representation, Delivery and Access to Construction Education. WINDS delivers individual education customisation by allowing the learner access through the Internet to a wide range of on-line courses and structured learning objects by means of personally tailored learning strategies. WINDS promotes the 3W paradigm: learn What you need, Where you want, When you require. Construction Practice. Construction industry is a repository of ""best practices"" and knowledge that the WINDS will profit. WINDS system benefits the ISO10303 and IFC standards to acquire knowledge of the construction process directly in digital format. On the other hand, WINDS reengineers the knowledge in up-to-date courses, educational services, which the industries can use to provide just-in-time rather than in-advance learning. WINDS IT Solutions The missions of the WINDS project state many challenging requirements both in knowledge and system architecture. Many of the solutions adopted in these fields are innovative; others are evolution of existing technologies. This paper focuses on the integration of this set of state-of-the-art technologies in an advanced and functionally sound Computer Aided Instruction system for A/E/C Design. In particular the paper deals with the following aspects: Standard Learning Technology Architecture The WINDS system relies on the in progress IEEE 1484.1 Learning Technology Standard Architecture. According to this standard the system consists of two data stores, the Knowledge Library and the Record Database, and four process: System Coach, Delivery, Evaluation and the Learner. WINDS implements the Knowledge Library into a three-tier architecture: 1.Learning Objects: ·Learning Units are collections of text and multimedia data. ·Models are represented in either IFC or STEP formats. ·Cases are sets of Learning Units and Models. Cases are noteworthy stories, which describes solutions, integrate technical detail, contain relevant design failures etc. 2.Indexes refer to the process in which the identification of relevant topics in design cases and learning units takes place. Indexing process creates structures of Learning Objects for course management, profile planning procedures and reasoning processes. 3.Courses are taxonomies of either Learning Units or a design task and Course Units. Knowledge Representation WINDS demonstrates that it is possible and valuable to integrate a widespread design expertise so that it can be effectively used to produce a high level standard of education. To this aim WINDS gathers area knowledge, design skills and expertise under the umbrellas of common knowledge representation structures and unambiguous semantics. Cases are one of the most valuable means for the representation of design expertise. A Case is a set of Learning Units and Product Models. Cases are noteworthy stories, which describe solutions, integrate technical details, contain relevant design failures, etc. Knowledge Integration Indexes are a medium among different kind of knowledge: they implement networks for navigation and access to disparate documents: HTML, video, images, CAD and product models (STEP or IFC). Concept indexes link learning topics to learning objects and group them into competencies. Index relationships are the base of the WINDS reasoning processes, and provide the foundation for system coaching functions, which proactively suggest strategies, solutions, examples and avoids students' design deadlock. Knowledge Distribution To support the data stores and the process among the partners in 10 countries efficiently, WINDS implements an object oriented client/server as COM objects. Behind the DCOM components there is the Dynamic Kernel, which dynamically embodies and maintains data stores and process. Components of the Knowledge Library can reside on several servers across the Internet. This provides for distributed transactions, e.g. a change in one Learning Object affects the Knowledge Library spread across several servers in different countries. Learning objects implemented as COM objects can wrap ownership data. Clear and univocal definition of ownerships rights enables Universities, in collaboration with telecommunication and publisher companies, to act as "education brokers". Brokerage in education and training is an innovative paradigm to provide just-in-time and personally customised value added learning knowledg

Intercellular Bridges in Vertebrate Gastrulation

The developing zebrafish embryo has been the subject of many studies of regional patterning, stereotypical cell movements and changes in cell shape. To better study the morphological features of cells during gastrulation, we generated mosaic embryos expressing membrane attached Dendra2 to highlight cellular boundaries. We find that intercellular bridges join a significant fraction of epiblast cells in the zebrafish embryo, reaching several cell diameters in length and spanning across different regions of the developing embryos. These intercellular bridges are distinct from the cellular protrusions previously reported as extending from hypoblast cells (1–2 cellular diameters in length) or epiblast cells (which were shorter). Most of the intercellular bridges were formed at pre-gastrula stages by the daughters of a dividing cell maintaining a membrane tether as they move apart after mitosis. These intercellular bridges persist during gastrulation and can mediate the transfer of proteins between distant cells. These findings reveal a surprising feature of the cellular landscape in zebrafish embryos and open new possibilities for cell-cell communication during gastrulation, with implications for modeling, cellular mechanics, and morphogenetic signaling

Deep renovation methodology for 20th-century masterpieces: the case of Palazzo Affari by Carlo Mollino

This paper proposes a methodological approach to energy renovation in valuable buildings, encompassing architectural, historical, and energy analyses. The research tests its application on a case study: a retrofit proposal for Palazzo Affari in Turin, an office building designed by Carlo Mollino for the Chamber of Commerce (1964–1974). The building, still in use, has never been thermally renovated yet. Palazzo Affari gathers structural, technological, and spatial experimentation worth to be preserved. The core of Mollino's design is a versatile plan, clear from any structural encumbrances, which was made possible thanks to an innovative structural technique. Façades are cladded with finely designed concrete prefabricated panels. As a 20th-century masterpiece, it must be recognized as culturally valuable but also shows enormous energy improvement potential, as many buildings of its age. Based on a deep understanding of the building, the paper proposes a combination of traditional and innovative ad hoc solutions for its renovation, mediated by the need for material and iconic preservation. Both the substitution of the façade panels and the insulation from the outside are excluded. The opaque parts of the façade are insulated from the inside using high-performance Vacuum-Insulation-Panels, and cladded by a new counter-facade conceived to be produced in panels through digital fabrication. On the other hand, windows are fully replaced by choosing glass which is both high-performing and respectful of the original chromaticity and transparency. The new window frames with thermal break are specially designed to respect the original external thickness. The design is configured as an add-in intervention, coherent with the pre-existence. Substitutions are carefully weighted and respect the original architectural features. FEM analysis demonstrates the reduction of the thermal flux through the opaque walls by 80% and through the windows by 65%. The solar factor is reduced by 35%, thus improving the summer internal thermal comfort

Urban Morphology Ontology

Urban Morphology Ontology (UMO) is a way of reading the contemporary city, highlighting the components (‘concepts’ in the broader definition of a generic ontology) and the relationships among them. The components are defined as urban elements. The purpose of this interpretation is to define a set of entities, and the relations between them, that can be used to describe and to compose urban fabrics. UMO offers a vocabulary of the domain composed by the urban objects and their properties; the knowledge of spatial and composition relationships defines the constraints that regulate the possibilities of combination of the single objects into urban fabrics. UMO implements four reference classes that map the hierarchical main morphological levels of objects: Root class: Geometrical families. This class tries to divide the urban space elements starting from their intrinsic dimensional nature: lines (i.e. elements with a standard cross section, developed along a path, like the streets), surfaces (i.e. every open and non-covered space), volumes (i.e. every building over covered space). This class contains also a primary distinction between the public/private conditions (for the linear elements and the surfaces), and between the closed or open volumes. Subclass 1: Functional families. In this class of the Urban Ontology there is a distinction among the main functional families of the elements, such as building, green etc. Subclass 2: Architectural typologies. This class articulates the typological peculiarities of the entities, such as semi-detached building or office block etc. Subclass 3: Distribution type / internal organisation. In this last class there are some information about the details of the structural schemes (e.g. single, double o multiple span) or about the internal organisation of the entities. This last class matches with the dimensional features, specified for every single element. UMO implements five different types of relationships between class individuals: • hypernym-hyponym relationships (subclasses and superclasses); • holonym-meronym relationships; • pertinence relationships; • spatial relationships; • size relationships

From the building refurbishment to the urban regeneration of the Quartiere Cogne of Aosta. A multidisciplinary approach

The Quartiere Cogne was erected at the beginning of the last century to house workers and managers employed at the new steel works. The whole neighbourhood is now affected by a wide-ranging transformation project which combines the features of aspects which really pertain to architectural building refurbishment within a broader framework of urban regeneration. Part of this project is financed by the National Programme for the Quality of Living. The design develops dwelling models aimed at strengthening the social structure at various levels (family, block, community, neighbourhood, local associations), making the most of local features. It includes initiatives to foster inclusion based on a broad network of infrastructures and services. An important feature is transition spaces, semi-private and semi-public, in which the idea and the quality of community is challenged. The aim is to give more natural and sustainable responses to instances of sharing and common use for collective housing in the Alpine area
