title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

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.

title	Análise da Emissão de CO2 em Edificações através do Uso de uma Ferramenta CAD-BIM [Analysis of CO2 emission in construction using a CAD-BIM system]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The main objective of this research is to determine through the use of a CAD-BIM system, the emission of CO2 in the pre-operational phase of construction. Based on a case study in quantitative analysis of materials and the BIM system, it was possible to quantify the amount of CO2 emitted during the pre-operational life cycle of a building. By using this feature you can provide, before the begining of construction, the total CO2 that will released to the environment, and other analysis.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 451-476.
summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title	Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary	In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

summary	Today, 98% of megaprojects face cost overruns or delays. The average cost increase is 80% and the average slippage is 20 months behind schedule (McKinsey 2015). It is becoming increasingly challenging to efficiently support the scale, complexity and ambition of these projects. Simultaneously, project data is being captured at growing rates. We continue to capture more data on a project than ever before. Total data captured back in 2009 in the construction industry reached over 51 petabytes, or 51 million gigabytes (Mckinsey 2016). It is becoming increasingly necessary to develop new ways to leverage our project data to better manage the complexity on our projects and allow the many stakeholders to make better more informed decisions. This paper focuses on utilizing advances in data mining, data analytics and data visualization as means to extract project information from massive datasets in a timely fashion to assist in making key informed decisions for project delivery. As part of this paper, we present an innovative new use of these technologies as applied to a large-scale infrastructural megaproject, to deliver a set of over 4,000 construction documents in a six-month period that has the potential to dramatically transform our industry and the way we deliver projects in the future. This paper describes a framework used to measure production performance as part of any project’s set of project controls for accelerated project delivery.

summary	The deconstruction (DeCon) and repurposing (ReCon) of existing structures and materials are worthwhile and relevant endeavors given the potential for such procedures to be more economically and environmentally sustainable than conventional construction methods. Conventional construction methods often utilize virgin materials for the production of architecture, requiring extensive energy to harvest, process, and manufacture the materials for use. Today, we must face the fact that we exist in a carbon-sensitive economy, and demand design approaches that reduce architecture’s impact on the environment. Our goal was to develop a CADCAM ReCon design methodology that would have the potential to mitigate carbon consumption. To explore this goal, students engaged a design research project that looked for novel and innovative approaches to the DeCon and ReCon of an existing barn. The student researchers created parametric models and surface designs derived from the existing materials. The digitally fabricated tectonic design constructions resulted in economical, novel, and material-efficient design methodologies for DeCon and ReCon.

summary	Recent advances in architectural and engineering technology have opened the door for complex architectural expression in today’s built environment. When pushing the envelope on geometric complexity, architects and engineers must begin a dialogue early on in the design process and communicate effectively throughout. Using digital models for communication, visualization, and analysis creates additional digital information that may need to be shared. Middleware provides interoperability between different software packages and facilitates the exchange of information. However, this does not exempt the partners from maintaining traditional lines of open communication. This paper will discuss the importance of open communication and demonstrate a strategy for sharing digital information. The case studies that will be presented are taken from design projects whose geometric complexity required close partnership between design team members. Effective communication will first be discussed in the context of three sculptural concept designs. Second, the interoperability of digital models will be discussed through a case study of a complex, faceted super-tall high-rise tower.

summary	The objective of this paper is to demonstrate that digital fabrication has had little impact in the Brazilian architecture so far, as compared to other countries, not because of an alleged unavailability of CNC technology in this country’s construction industry, but for other reasons that must be investigated. We show in this paper the results of a preliminary survey carried out in the region of Brasilia that reveals a significant presence of CNC technology in the local construction industry which points to new opportunities for innovation in the architectural field.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The knowledge of latest technology that allows the development of competitive products in reduced times is crucial to guarantee a sustainable growth of the national industry. This work presents the development of a computational system for the Virtual Design of products, the VirtusCADE, which is a CAD/CAE interactive software (Computer Aided Design/Computer Aided Engineering). The VirtusCADE includes 3D geometric modeling of surfaces and solids and mesh generation. The system uses the parametric modeling of surfaces, including algorithms for determination of intersection between surfaces and for triangular mesh generation in trimmed parametric surfaces. The graphical interface is interactive and allows the direct real time manipulation of objects (lines, surfaces and solids) in 3D using the OpenGL technology. The system prioritizes the usability, implementing several graphic tools that facilitate the manipulation in 3D. The VirtusCADE contemplates the structural simulation through the Finite Element Method. The code architecture is based on oriented object programming, which allows great scaling capability for the implementation of new tools. This project has great applicability in numerical simulation of physical phenomena, such structural analysis of buildings, vehicles parts, with impact in the industries of civil construction, metal-mechanics, aerospatial, naval and automotive.

title	Parametric Constructionist Kits: Physical Design and Delivery System for Rapid Prototyping Devices
source	International Journal of Architectural Computing vol. 7 - no. 4, 623-642
summary	In this paper we illustrate a design methodology based on constructionist learning principles with CAD modeling and rapid prototyping. The belief is that a constructionist approach to design development extends design possibilities beyond the visual aspects of rendering and animation to building construction by way of component-based parametric modeling. This is demonstrated by way of construction kits as a proposed system of physical design production, individually and in groups. Results of the system are data sets for model manufacturing, hand assembly and design feedback. The impact of this work is to teach physical modeling as a system of production that will allow a designer hands-on learning of building structure, material mechanics and building component behavior. Also design success is newly defined as a relationship between the visual and physical evaluation; not just the visual. The paper ends with examples of complex design models generated from elements in the construction kit and a physical design grammar used to guide element assembly. Although the examples in this paper satisfy model making for building structures we believe this system can be useful for anyone who needs to construct physical artifacts beyond traditional scales found in rapid prototyping.

summary	This paper addresses the importance and development of cultural transformations involving the design process in architecture and the advent of Building Information Modeling (BIM) in civil construction activities and how its implementation in a coordinated, collaborative and interoperable way contributes to a diagnosis of Clash Detection between diferentes design projects, before building construction, saving excessive costs and rework. Taking as its main reference the BIM Maturity Matrix of Succar (2009), the proposed BIM Project Integration Maturity Matrix contributes to the awareness of bringing designers and builders closer to design activities, to encourage the integration of design processes involving the building, to consolidate an environment of ease of communication between participants, the organization of documentation and, above all, prioritize the compatibility between projects to avoid conflicts, excess costs and rework, resulting in a higher quality of the final project.

summary	Building Information Modeling (BIM) has the potential to fundamentally alter the way composition, scale and abstraction are addressed in today’s comprehensive design studio by displacing the primacy of abstract conventions of representation with a methodology based on systems thinking and virtual simulation. BIM viewed as provocateur of design education provides great potential for the critical analysis of how architectural design is taught. The design studio project reflects new ways of teaching and addressing BIM methods and processes, and critically evaluating their effects and possibilities on architectural production.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Testing the relevance of parameterization to architectural epistemology
source	Architectural Science Review, Volume 52.2: 135-141
summary	Advances in building information modeling (BIM) deeply impact the production of new architecture; its benefits are obvious and its acceptance widespread. But how does BIM impact the study of existing architecture? Can BIM be assumed to operate as a neutral framework, equally applicable to the study of architecture anywhere? Using as a point of departure a recent outline of the conceptual structure of parametric modeling prepared by Sacks, Eastman, and Lee (2004), this paper compares parametric models of two existing works of architecture: Mies van der Rohe’s Crown Hall and Peter Zumthor’s St. Benedict Chapel. The processes of parametrically modeling each building are specifically compared in two ways: first, parameters are established for each model; second, each model is "flexed" as a means of disclosing possible semantic relationships within each work of architecture. Because each building demands a different parameter-establishment strategy, and because the models permit different degrees of flexibility, the comparison illustrates the shortcomings of a "neutral framework" assumption to an architectural epistemology.

title	The impact of digital architecture design in the conception and management of dwelling environments
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	When technology moves forward, architecture changes with it: it changes the architecture methodology and it changes the architectural result. This paper discusses the variables involved, pointing the major constraints to the intensive use of ICT in the architectural process. It highlights the need to rethink the user’s involvement in the conception of the built environment, increasing it, and suggests new approaches to meet this need by using ICT and VR.

title	Services in Digital Design: new visions for AEC-field collaboration
source	International Journal of Architectural Computing vol. 7 - no. 3, 459-478
summary	The objective of this paper is to describe contemporary digital building design from a service provider aspect. The constrained framework of this work is digital architectural design practice. When design is seen in the context of the AEC field, a process oriented approach is commonly used in describing collaboration and evolutionary progress of the design work as a project. Design projects are scheduled chains of activities which result in design delivery or actual physical buildings as the end products of the project. Recently developments in building information modelling (BIM) have presented fundamentally new ways for collecting, exploring, and sharing design information. This study develops the novel digital approach: BIM as design services. The key finding of the study is that parts of the design domain can be described as services in the changing digital environment. The scientific contribution of this paper is in describing contemporary digital design practice with an alternative service approach. A framework for such services is also presented. This work will expand the authors' contribution to research on preliminary architectural design using building information models.

title	BIM Maturity Index: Analysis and Comparison of Architecture Office’s BIM Performance in Porto Alegre
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 508-515
summary	This study evaluated the BIM Maturity Levels of architecture offices in Porto Alegre (Brazil) by adapting the method developed by Succar (2009). It was carried out by applying a questionary in face-to-face interviews and converting the qualitative data obtained into quantitative, ultimately generating the BIM Maturity Index: a percentage number that can be classified and compared. The preliminary results indicate a significant discrepancy in BIM competences between the case studies while reasserting challenges faced by them in a regional scope: the scarcity of external stakeholders appropriately inserted on the BIM process and the undersupplied BIM knowledge offered in academic courses.
