title	Collaborative design for existing architecture: the Building Information Modeling as a frontier for coordinated process
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 96-100
summary	Building Information Modeling (BIM) has been considered as an emerging collaborative strategy since its introduction, meant for AEC industry and heading to benefits in terms of costs and design quality during the whole building lifecycle. BIM approach, originally developed for new projects, can be successfully applied to existing contexts using TLS surveys to collect point clouds and turn them later into smart digital models, taking advantage of new technologies and methods. This paper addresses these themes paying attention to issues and opportunities, considering BIM as a paramount tool to collect and manage data destined to multiple disciplines

title	Three Dimensional Reconstitution of an Old Town from Historical Documents: Case of the Medina of Jijel in Algeria
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 191; 285-303
summary	The three-dimensional reconstitution of cities and urban tissues was the subject of several studies and researches. In order to obtain the acquisition of the geometry of architectural or urban sets, some studies are based on Photogrammetric or on computer vision. Others have focused on the development of tools of acquisition from a laser providing a 3D scatter plot. Some of them yet focused towards the development of CAD software. The automatic generation for morphological 3D representation based on the exploitation of the architectural knowledge basis is also an option. This type of work becomes more relevant and legitimate when it concerns old cities in state of ruin or more simply missing whose remains only prints or literary descriptions similar to our case study; the old town of Jijel that many people ignore its existence. The aim of this work is to achieve a 3D reconstitution of buildings of this town based on historical documents, mostly prints, digitized old maps and plans, as well as literary texts (tales of travelers, military records, and history books). The method developed can solve and generate possible urban volumes in the most frequent cases. The 3D model obtained, despite its geometric simplicity, can view the city from different angles and open new opportunities for research in history, architecture and town planning.

title	Protótipo rápido de elementos construtivos produzidos pela tecnologia de sinterização seletiva a laser [Rapid prototyping of constructive elements produced by the technology of selective laser sintering]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 669-672
summary	The aim of this paper is to examine the physical models of constructive elements from the use of technology of selective laser sintering (SLS). The main stages in the production of rapid prototyping (PRs) were as follows: 1. Parametric Modeling (MP); 2. Geometric modeling; 3. Preparation of geometric model; 4. Execution of PR. This research contributes to debate on parametric modeling (MP) and the fabrication of very delicate physical models by technology SLS, particularly for purposes of viewing and technical evaluation during the design process in architecture.

title	Reflexão sobre seis residências emblemáticas a partir da tecnologia BIM e da fabricação digital [Reflection on emblematic residences from static / dynamic simulations and digital fabrication]
source	SiGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay - Montevideo 12 - 14 November 2014, pp. 311-315
summary	The aim of this paper is to report the teaching experience held in 2012 at Unicamp between three disciplines of representation. Students analyzed emblematic residences from digital and physical models. Digital models were produced in Revit and its building components were diagrammed in AutoCad. After that, these elements were sent to laser cutter, and hand assembled. In 3DS Max, 3D model allowed simulations such as rendered images and animations. We report the contributions of these analog and digital artifacts in the design process. This article contributes to reflection and debate on the application of digital technologies in the analysis of iconic buildings of architecture.

title	A Method for the Realization of Complex Concrete Gridshell Structures in Pre-Cast Concrete

summary	This paper describes a method for the design and fabrication of complex funicular structures fromdiscrete precast concrete elements. The research proposes that through the integration of digitalform-finding techniques, computational file-to-fabrication workflows, and innovative sustainableconcrete casting techniques, complex funicular structures can be constructed using prefabricatedelements in a practical, affordable, and materially efficient manner.A recent case study is examined, in which the methodology has been used to construct a pavilion.Custom-written dynamic relaxation software was used to define the overall form and successivealgorithms; it then defined each component’s unique geometry, unrolled into flat shapes, andnested all parts into cut-files. PETG plastic sheets were two-dimensionally laser cut and folded toproduce the unique casting molds. The case study was carried out in collaboration between theAarhus School of Architecture and the University of Technology, Sydney (UTS). Basic research incasting techniques defined the framework for the design process, and a custom-written dynamicrelaxation software application became the primary form-generating tool in the design process ofa constructed pavilion. Fabrication and construction constraints were embedded within the designof both the overall structure and its components. Finite element analysis [FEA] was completed inorder to verify the form-finding results, to ensure structural stability, and to direct adjustments ofthe structure during the design process.The constructed pavilion case study, constructed in a very short time, for low cost and with relativelyunskilled labor, demonstrates that the integration of algorithmic form-finding techniques, CNCfabrication workflows, and the use of innovative PETG folded-mold techniques enables thepractical realization of freeform funicular structures in precast concrete.

summary	Digital Fabrication has arguably stirred the return of the architect to the long-held position as a master builder. The close engagement with materials offered by the digital fabrication technologies places necessary limitations and calls the architects for a deeper understanding of and awareness about the fabrication realities during the design process. The research conducted uses parametric modeling for the alteration of the design according to a wide range of infl uences, one of which is fabrication. This paper offers a close perspective on some fabrication necessities and limitations that emerged through the manufacturing of a number of scaled models of a parametrically designed shed and a full scale pavilion. The scope of this work falls into the realm of physical testing, tolerance, structure and assembly. It also points out the fabrication parameters that were part of the digital setting used to create the physical models. The paper argues that craft is still practically alive when deploying digital technologies as it has been ever present in the pre-digital era.

title	Relaciones in-formadas entre la investigación y la enseñanza de morfología [In-formed relationships between morphology investigation and teaching]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 308-311
summary	This paper describes two case studies in which digital media and morphology are closely related. The first one refers to the evolution of the different instruments applied in a research area comprising spatial surfaces generated by double rotation. The second one deals from the start with laser cutting, and its possibilities of providing flexibility to rigid sheets through density and shape of the incisions. It presents the latest results in the development of joint design for this kind of products. Finally, the current trends in our research are briefly mentioned.

title	Machinic Morphospaces: Biomimetic Design Strategies for the Computational Exploration of Robot Constraint Spaces for Wood Fabrication
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 157-168
doi	https://doi.org/10.52842/conf.acadia.2012.157
summary	The paper presents research into computational design processes that integrate not only criteria of physical producibility but also characteristics of design intelligence and performance. In the first part, the use of an industrial robot’s design space for developing differentiated finger joint connections for planar sheets of plywood is being introduced. Subsequently, biomimetics is proposed as a filter for the possible geometric differentiations with respect performative capacities. The second part focuses on the integration of fabricational and biomimetic principles with structural and architectural demands, as well as by the development of a custom digital data structure for the fabrication of finger joint plate structures resulting in the construction of a full scale prototype. The paper concludes with evaluating the tolerances inherent in construction through 3D laser scan validation of the physical model.

title	Building Thailand's tallest Ganesh: CAD/CAM integration in conventional metal fabrication
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 337–346
doi	https://doi.org/10.52842/conf.caadria.2012.337
summary	Ganesh (Ganesa or Ganesha) is a Hindi god well known for his distinguishable elephant head and widely revered as the god of success or remover of obstacles. Patrons in Thailand have worshipped Ganesh and respected him by means of erecting statues of Ganesh in various poses and sizes throughout the country. In late 2008, the people of Chacheongsao, a province located East of Bangkok, decided to create Thailand’s tallest standing Ganesh statue made with bronze reaching heights up to 39 meters and situated on the Bangpakong river bank overseeing the city and its people. The author and design team was approached by representatives from Chacheongsao and commissioned to advise the process from conception to construction. The challenge started with seeking appropriate computer-aided design and manufacturing technologies and innovative processes to guide the design team throughout the production. The 0.60-meter bronze cast sculpture of the Ganesh was scanned using a 3D optical scanner to generate a solid model of the statue. A surface model was then extracted from the 3D model to firstly determine the most efficient structural support within the statue and secondly to generate surface strips for the foundry to create actual bronze casts. The construction of the project began early 2009 and the statue has since been erected from its base to currently its head. During construction, the author and design team has encountered several problems translating pixels to parts. Several errors have occurred during the mould and cast production process as well as construction errors on site causing mismatches of the structure and surface, misalignments, and protruding structural supports and joints. The lessons learned from this project is documented and analysed with hopes to create a more effective process for future projects with similar requirements.
