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	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary	Architectural design education can benefit from incorporation of 4D CAD techniques into a BIM-enabled process for rapid design and assessment of alternatives. Experimental courses conducted at two universities provide evidence that graduate students possessing modest skills with BIM software can adopt 4D CAD methods and integrate them into their design process with minimal effort. The method enables student teams to gain insight into the construction issues of their designs and iteratively improve design alternatives.

summary	In recent years a number of projects have been emerged, in which the new possibilities of the computer as a design tool, have been used. Through the digital chain from design to manufacturing the efficiency has increased and allows the implementation of complex architectural structures. With all these new opportunities, also new challenges arise in the teaching and the educational concepts. The paper describes the detailed course concept and the didactic strategy using the example of a parametric designed roof structure, we designed, planed and build up in scale 1:1 within the main course. „Wendepunkt\|e im Bauen“ (Turning point\|s of building) is the name of an exhibition at the “Pinakothek der Moderne” in Spring 2010. In addition to contributions of the industrialization in the building industry from 1850 to the present day, the exhibition also serves as a platform, to demonstrate new possibilities of computer-aided parametric design and the closely related computer aided manufacturing (CAM). In this context, we took the chance to build a sculpture in Scale 1:1 to show the potential of a constant digital workflow and the digital fabrication. Through the digital chain from design to manufacturing, the efficiency has been increased by the computer and allows the implementation of new complex architectural structures. But the efficiency of the high-degree-automation through the use of computerized machines usually ends in the production of the components. Because this coincidence of the elements in the assembly often proves cost and time, the aim of the project was to optimize both, the production of components and their assembly as well. As part of the wintercourse 2009/2010 different aspects of automation have been reviewed and new solutions have been analyzed. Together with 15 students of the Faculty of Architecture the complete digital chain started with the first design ideas, about parametric programming through production and assembly had been researched, implemented and brought to reality. In the first steps, the students had to learn about the potential, but also about the problems coming with the digital-design and the attached digital-production. There for the course took part at our computerlab. In weekly workshops, all ideas have been implemented and tested directly in the 3-dimensional parametric model. And thanks to the interdisciplinary work with the Department of Structural Design also static factors had been considered, to optimize the form. Parallel to the digital form-finding process, the first prototypes have been produced by the students. By using the chairs 3D-CNC-Mills we were able to check the programmed connection detail in reality and apply the so learned lessons to the further development. After nearly 3 month of research, designing, planning and programming, we were able to produce the over 1000 different parts in only 4 days. By developing a special pre-stressed structure and connection detail it was also possible, to assemble the whole structure (13.5m x 4.5m x 4m) in only one day. The close connection between digital design (CAD) and digital manufacturing (CAM) is an important point of our doctrine. By the fact, that the students operate the machines themselves, but also implement projects on a scale of 1:1, they learn to independently evaluate these new tools and to use them in a meaningful way.

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	Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

summary	Currently BIM is at the forefront of the building industry. While useful for various building types the definitive nature of healthcare design benefits from the BIM process largely in comparison to other building types.

doi	https://doi.org/10.52842/conf.ecaade.2017.2.347
summary	The Waiheke Gateway Pavilion, designed by Stevens Lawson Architects originally for the 2010 New Zealand Venice Biennale Pavilion, was brought to fruition for the 2017 Headland Sculpture on the Gulf Sculpture trail by students from Unitec Institute of Technology. The cross disciplinary team comprised of students from architecture and construction disciplines working in conjunction with a team of industry professionals including architects, engineers, construction managers, project managers, and lecturers to bring the designed structure, an irregular spiral shape, to completion. The structure is made up of 261 unique glulam beams, to be digitally cut using computer numerical control (CNC) process. However, due to a malfunction with the institutions in-house CNC machine, an alternative hand-cut workflow approach had to be pursued requiring integration of both digital and analogue construction methods. The digitally encoded data was extracted and transferred into shop drawings and assembly diagrams for the fabrication and construction stages of design. Accessibility to the original 3D modelling software was always needed during the construction stages to provide clarity to the copious amounts of information that was transferred into print paper form. Although this design to fabrication project was challenging, the outcome was received as a triumph amongst the architecture community.

doi	https://doi.org/10.52842/conf.caadria.2010.585
summary	This paper explores how fabrication-based criteria can be integrated into design processes through computational methods. Based on the ongoing project of the Library of the Bao’an Cultural Complex in Shenzhen, China (referred as ‘the Library’ in this paper hereafter), this paper discusses the process of the rationalisation of an intuitive architectural form and its subsequent tiling design based on the adaptation to the conventional fabrication techniques of the building façade industry in China. These objectives are followed by the establishment of robust computational systems of automation that provide a concrete basis for the visualisation, the development of envelope details, and the generation of the list of component data for fabrication. This integrative approach is markedly different from a more conventional one, in which computational systems serve as a priori solutions to unconstraint design sketches.

doi	https://doi.org/10.52842/conf.caadria.2010.303
summary	The recent developments in digital technologies and contemporary design tools are initiating new approaches of form-finding based on parametric development of multiple geometries with simultaneous consideration of various aspects. This paper focuses on the use of advanced parametric CAD systems and reformulated construction logics to enhance the potential and possibilities of form finding processes. This approach is exemplified through the “Greenhouse Trauttmansdorff project”. The project demonstrates a form finding approach which is based on defined parameters that not only fulfil aesthetic and functional aspects, but simultaneously take structural properties and the resulting sun shading behaviour into account. We will explore within this paper how – next to the functional and contextual building requirements – required illumination levels inside the greenhouse create a feedback loop between the structural system and its cladding system.

title	Preserving memories with digital media: a methodology for the reconstruction of Castelnuovo Village
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 83-92
doi	https://doi.org/10.52842/conf.caadria.2010.083
summary	The historical centre of the village of Castelnuovo (located in Abruzzo, a region in central of Italy) was seriously damaged by the earthquake of the 6th of April 2009. Following the survey by the Civil Protection, all dwellings have been classified as unsuitable for habitation. The village should be either abandoned or totally rebuilt. But which is its value? Is there something worth of being preserved? If observed from a biodiversity point of view, or more precisely from a “cultural biodiversity” point of view, the historical centre possess interesting materials and immaterial characteristics. These qualities constitute real guidelines for a possible recovery project. Since there is not any possibility to make a survey of the inner village because of its destruction by the earthquake, in this research we have decided to use information technology, in order to rebuilt it and study it in a three-dimensional environment. In this paper we describe the theoretical basis, the method of elaboration and the instruments we have used to locate and evaluate the memories that should be preserved in a new project. Starting with a traditional documentation, such as photographs and drawings, we have used a variety of software (graphics editing program, CAD, 3D modeler, videogame 3D-engine), because of the several hypothesis considered.

title	Patterns, heuristics for architectural design support: making use of evolutionary modelling in design
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 283-292
doi	https://doi.org/10.52842/conf.caadria.2010.283
summary	Software used by architectural and industrial designers has shifted from becoming a tool for drafting, towards use in verification, simulation, project management and remote project sharing. In more advanced models, design parameters for the designed object can be adjusted so that a family of variations can be produced rapidly. With the advances in computer aided design (CAD) technology, design options can now be generated and analyzed in real time. However the use of digital tools to support design as an activity is still at an early stage and has largely been limited in functionality with regard to the design process. To date, major CAD vendors have not developed an integrated tool that is able to leverage specialised design knowledge from various discipline domains (known as expert knowledge systems) as well as to support the creation of design alternatives that satisfy different forms of constraints. We propose that evolutionary computing and machine learning be linked with parametric design techniques in order to monitor a designer’s cognition and intent based on their design history. This will lead to results that impact future work on design support systems which are capable of supporting implicit constraint and problem definition for wicked problems that are difficult to quantify.

summary	Digital Heritage has gained popularity recently as means of dynamically representing and reconstructing historic buildings and cityscapes. Simultaneously this new medium of visualization affords another approach to examine human-virtual environment interaction and offers possibilities of exploiting virtual environments as educational tools. At Zayed University, a federal university primarily for women citizens of the United Arab Emirates, we have integrated student-faculty research and documented and reconstructed a number of historical buildings within the curriculum of the Department of Art and Design. We have further collaborated with the animation program at Winston Salem State University in North Carolina, utilizing the motion capture laboratory at the Center of Design Innovation to literally breathe life into these reconstructions. The primary idea is to contribute to the ongoing documentation of the country’s heritage through creating “responsive virtual heritage environments” where the spectator is actively engaged in exploring the digital space and gain certain degrees of control over the course and scheme of the dynamic experience. The process begins by introducing students to utilize the diverse capabilities of CAD and three dimensional computer applications and intertwine the technical skills they acquire to construct virtual computer models of indigenous built environments. The workflow between the different applications is crucial to stimulate students’ problem solving abilities and tame the application tools, specifically when constructing complex objects and structural details. In addition the spatial and temporal specificity different computer applications afford has proven useful in highlighting and analyzing the buildings’ function within the extreme climate of the country and their role in the political-economy, particularly in visualizing the ephemeral qualities of the architecture as they relate to passive cooling and the inter-relationships between built and natural environments. Light and time settings clarify shadow casting and explain the placement and orientation of buildings. Particle simulations demonstrate the harnessing of wind and rain both urban and rural settings. The quantitative data accumulated and charted through CAD and VR programs and geo-browsers can be integrated with qualitative data to create a more holistic analytical framework for understanding the complex nature of past settlement patterns. In addition, the dynamic nature of this integration creates a powerful educational tool. This paper reviews this ongoing research project with examples of reconstructions completed across the country, demonstrating analytical and educational possibilities through the integration of CAD programs with a range of other statistical, geographic, and visualization software.

summary	This paper introduces a JAVA based library for parametric modeling through programming. From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depends on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations. We introduce key concepts of the library and show a use of the library within a form finding process driven by irradiance simulation.

source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 222-228
summary	This paper integrates traditional techniques with the parametric approach in ceramic fabrication by outlining several key parameters in both the traditional and digital ceramic fabrication process, and investigating how these parameters can accommodate parametric variation from the digital model. Findings from three experiments with different parameters suggest a promising landscape for traditional ceramic fabrication to be more compatible, not only with the parametric variation in digital modeling, but also with customized digital fabrication.

summary	This paper demonstrates how digitally fabricated vacuum-formed components can provide a new type of efficient construction applicable to architecture. Vacuum forming has the advantage of rapid mass-production capability of 3D curved forms. Recent digital fabrication technologies, such as 3D CAD and CNC machining, have dramatically reduced the cost and time for making the mould. In combination with biodegradable plastic, such as PLA (poly lactic acid) made of biopolymer, it could open up new type of sustainable construction system, which is applicable for temporal disaster housings or exhibition booths.
