title	Computer Aided Dimensional Control in Building Construction
source	Eindhoven University of Technology
summary	Dimensional control in the building industry can be defined as the operational techniques and activities that are necessary, during the construction process of a building, for the assurance of the defined dimension quality of a building (Hoof, 1986). Efficient and precise dimensional control of buildings under construction is becoming ever more important because of changes in the construction industry. More prefabricated components are used; more regulations appear; newly designed buildings have more complex shapes, and building construction is speeding up. To ensure the predefined dimensional quality, a plan of dimensional control must be designed, on the basis of building drawings and specifications delivered by architects, before the building is constructed. The dimensional control plan must provide site personnel with adequate information on, among others, setting out and assembling building components, which can often be done by means of Total Stations. The essence of designing a dimensional control plan is to find out which points should be used as positioning points, which points should be set out in advance or controlled afterwards, and not to forget why. In an effort to contribute to the improvement of the dimensional control of on-site construction projects, this research tries to capture the knowledge required to design an adequate dimensional control plan and make that knowledge more generally available, and build a digital connection between CAD systems and Total Stations, focusing on prefabricated concrete building structural elements. The instrument developed in this research for capturing of essential dimensional control information and knowledge makes use of Product Data Technology (PDT) and Knowledge Technology (KT). The chosen solution supports the stochastic analysis of optimal positioning points taking account of various sorts of deviations and their mutual relationships. The resulting information model has been written in a standardized information modelling language called UML (Unified Modelling Language). The model has been implemented in a Dimensional Control System (DCS) and applied in the “La Tour” construction project in Apeldoorn, the Netherlands. The DCS provides a digital way to bridge the floor plan design with dimensional control, predict dimensional deviation limits and output the data needed for a Total Station. The case study of “La Tour” tests the UML model and prototype of the DCS. The results prove that direct positioning of objects (by putting reflectors on the objects and using a Total Station and by inputting coordinates extracted and calculated from the AutoCAD drawings) provides higher speed, accuracy and reliability. It also shows a way to (pre)position free form objects in 3D where traditional methods cannot. In conclusion: (1) it seems to be justified to expect that the application of the DCS will contribute to increased confidence in dimensional control and the reduction of costs of failure, which potentially could support the increased use of cheaper construction methods, and will also contribute to the improvement of building design and construction process. (2) the scientific contribution of this research is a first step towards providing dimensional quality in a construction process covered by stochastic dimensional uncertainty, even for positioning of free form objects.

summary	This research applies Object Oriented Database (OODB) to relate and link building drawings and texts for the purpose of creating a PDA-based systemetic integration of construction-related design data. This system tries to solve the problems of data segmentation, inexpedient interrogation, and consistency in working drawing information management. Recently development of PDA has accelerated and functionally diversified. Under the speed of development, supervisions of construction projects can be conducted by PDA as a kind of tool as a primary information supplier or manager.

title	Automatic sensor evaluation in BMS commissioning of building refrigeration systems
source	Automation in Construction 11 (1) (2002) pp. 59-73
summary	A strategy and software is developed to automatically diagnose and evaluate the Building Management Systems (BMS) sensors of building refrigeration systems during commissioning or periodical check (recommissioning). The strategy is based on the first law of thermodynamics (i.e., heat and mass balance of water networks). The strategy evaluates soft sensor faults (biases) by examining and minimizing the weighted sum of the squares of the concerned mass and/or steady state energy balance residuals represented by the corrected measurements over a period, on the basis of the measurements downloaded from BMS. A Genetic Algorithm is employed to determine the global minimal solution to the multimodal objective function, which can be difficult to achieve by traditional gradient-directed search methods. The sensor bias estimates, the confidence intervals of bias estimates and the comparisons of the balance residuals before and after the correction are generated by the software to provide a convenient and reliable means for the engineers to check and diagnose the measurement devices of BMS. The strategy, the software configuration and examples of application are presented in this paper.

title	From CAD to iAD - A Web-based Steel Consulting of Steel Construction in Architecture
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 346-349
doi	https://doi.org/10.52842/conf.ecaade.2002.346
summary	Information technology has become so powerful that what is conventionally called CAD might evolve to iAD (Internet Aided Design) (Zhou 2000). For Internet applications in the AEC industry, most of the efforts and success have been concentrated on project management and collaboration, while in the design and engineering consulting area, limited progress has been made. At the same time, contemporary development has not changed the nature of the fragmentation of the AEC industry. Based on previous research of surveys of development of Internet applications in the AEC industry (Zhou 2001), and the proposal of conceptual model of Internet-based engineering consulting in architecture (Zhou2002), we try to apply these theories and concepts into a specified area, steel construction consulting for architects. In previous research, first of all, we defined the contents and scope of steel construction consulting and their potential application. Second, we proposed a solid working model covering structure organization, audience, services provided and technology. In this research, a web-based application will be out by prototyped by conducting a conceptual design consulting in steel structure in order to show the whole process of how this Internet-based consulting model works.

title	A National Strategy for CAAD and IT-Implementation in the Construction Industry the Construction Industry
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi	https://doi.org/10.52842/conf.ecaade.1997.x.o8u
summary	The objective of this paper is to present a strategy for implementation of CAD and IT in the construction and building management#1 industry in Sweden. The interest is in how to make the best use of the limited resources in a small country or region, cooperating internationally and at the same time avoiding to be totally dominated by the great international actors in the market of information technology. In Sweden representatives from the construction and building management industry have put forward a research and development program called: "IT-Bygg#2 2002 - Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry. The presented strategy is based on a seminar with some of the most experienced researchers, developers and practitioners of CAD in Sweden. The activities were recorded and annotated, analyzed and put together afterwards. The proposal in brief is that object oriented distributed CAD is to be used in the long perspective. It will need to be based on international standards such as STEP and it will take at least another 5 years to get established. Meanwhile something temporary has to be used. Pragmatically a "de facto standard" on formats has to be accepted and implemented. To support new users of IT all software in use in the country will be analyzed, described and published for a national platform for IT-communication within the construction industry. Finally the question is discussed "How can architect schools then contribute to IT being implemented within the housing sector at a regional or national level?" Some ideas are presented: Creating the good example, better support for the customer, sharing the holistic concept of the project with all actors, taking part in an integrated education process and international collaboration like AVOCAAD and ECAADE.

title	Integrating barcode and GIS for monitoring construction progress
source	Automation in Construction 11 (1) (2002) pp. 23-33
summary	This study focuses on developing an automated schedule monitoring system for precast building construction. Erection of prefabricated structural components is the major critical activity for precast building construction. An efficient lifting schedule and control plan can significantly reduce construction conflicts and project delay. In this research, the system ArcSched was developed to assist engineers in controlling and monitoring the erection process in a real time basis. ArcSched is composed of a Geographic Information System (GIS) integrated with a database management system. Through systematic monitoring of the construction process and representation of the erection progress in graphics and colors, the scheduled components for erection are repetitively tracked and well controlled to implement the lifting schedule as planned.

title	Interdisciplinarity: Perceptions of the Value of Computer Supported Collaborative Work in Design for the Built Environment
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 221-228
doi	https://doi.org/10.52842/conf.caadria.2002.221
summary	This paper presents the findings from a study into the current exploitation of CSCW in design for the built environment in the UK. The research is based on responses to a web-based questionnaire. Members of various professions including civil engineers, architects, building services engineers and quantity surveyors were invited to complete the questionnaire. The responses reveal important trends in the breadth and size of project teams at the same time as new pressures are emerging regarding team integration and efficiency. The findings suggest that while CSCW systems may improve project management (e.g. via project documentation) and the exchange of information between team members it has yet to significantly support those activities that characterize integrated collaborative working between disparate specialists. The authors conclude by combining the findings with a wider discussion of the application of CSCW to design activity – appealing for CSCW to go beyond multidisciplinary working to achieve interdisciplinary working.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	An accelerated subcontracting and procuring model for construction projects
source	Automation in Construction 11 (1) (2002) pp. 105-125
summary	Considering the characteristics of highly specialized corporation in the construction industry, it's crucial to select appropriate subcontractors to implement specific subprojects. In this research, the overall subcontracting supply chain of a construction project is considered as a global procurement system and an optimal combination of subcontractors can be obtained within this system. Combining the quick response mechanism of information technology with portfolio theory in financial management, an integrated XML (eXtensible Markup Language) of Accelerated Subcontracting And Procuring (ASAP) model was proposed. The ultimate goal of this study is not only to develop a web-based decision support system for general contractors to accurately decide an appropriate trade-off between risk and profit for different combinations of subcontractors, but to take the subcontracting and procuring process into re-engineering through omnipresent Internet.

title	A relational approach of cooperation in building design
source	International conference on concurrent enterprising, Rome
summary	The methods and models of the concurrent engineering taken from the industry domain are unsuitable for the domain of the construction, which is characterized by a singular context of cooperation. The existing groupware tools can not be directly used in the framework of the architectural conception. They require a high level of definition of procedures and exchanges, which is incompatible with the flexibility of current practices. At first, we present the particularity of the context of the building cooperation, then we illustrate through an experiment the problems put by the use of a groupware tool based on a hierarchical data organization. From this experiment, we justify the interest of building a new model of cooperation where the relational organization of the project is taken into account. The integration of this new dimension allows to propose to the user an adapted vision of the project by taking into account the role he plays inside the project.

title	Rapid prototyping and its application in architectural design
source	Automation in Construction 11 (3) (2002) pp. 277-278
summary	At the beginning of the 20th century, the clarion call of the Modern Movement was sounded to awaken architects to the purity and clarity of engineered and manufactured goods. In this aesthetic, the house was to be considered a manufactured item, drawing upon scientific and engineering logic for the design to be clarified and reduced to the essential. Mass production of the house would bring the best to a widemarket and design would not cater to the elite. At the start of the 21st century, the goal remains, although reinterpreted, with the process inverted. No longer does factory production mean mass production of a standard item to fit all purposes, i.e., one size fits all. Instead, we now strive for mass customization, bringing the benefits of factory production to the creation of a unique component or series of similar elements differentiated through digitally controlled variation.

summary	This paper is the culmination of a period of studying and participating in certain real project on environmental design with realtime simulation system application. The focus of this paper is on understanding that a generally real-time simulation system, can render a complex scene that consisted by a huge landscape model with millions polygons and building models with thousands details. It is also more than just a collection of unorganized techniques. This paper must dual with issues of scene elements management as a front end that efficiently provide the ability to process complex and moving objects in a physically realistic way. We establish a platform providing good support for the environmental designers.

title	A Representation Scheme for Integrated Building Performance Analysis
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	This paper presents a representational scheme for integrated building performance analysis. The underlying research work was motivated by the need for seamless exchange of structured design information.A comprehensive and widely accepted industry standard suitable for exchanging design information among the various AEC (Architecture/Engineering/Construction) applications has yet to emerge. As a contribution to this on-going discussion, we present a specific approach to the integration problem in building product modeling. This approach can be viewed as pragmatic or bottom-up in the sense that itwas driven by the informational needs of related individual domains (particularly in the early stages of design) rather than by a quest for a universally applicable solution. In this paper, we describe a schemawhich emerged from the SEMPER effort, a multi-year project aimed at supporting detailed performance analysis for early design in the energy, life-cycle analysis, lighting, and thermal comfort domains. Thisschema relies on a representational division of labor between a shared building model, and various disciplinary (domain) models. Specifically, we present a documentation of the shared object model together with disciplinary models for the energy, light, acoustics, and life-cyle assessment domain.

doi	https://doi.org/10.52842/conf.acadia.2002
summary	The 2002 ACADIA conference finds digital tec_nology ubiquitous as the Association for Computer Aided Design in Architecture moves into its third decade. The organization of ACADIA is on the threshold of restating its mission. After 20 years, many of the organization’s initial objectives have been achieved. ACADIA members have been instrumental in the development of design software, and in bringing computers and digital technology into architectural practice and design school curriculum. At first, ACADIAns faced the debate over the appropriateness and utility of digital technology in the disciplines of architecture, planning and building science. Today the use of computers and information technology is widely accepted by architects and CAAD and digital technology have brought profound change to design practice. The debate in ACADIA has long since moved from "should we use this technology" to "how", "for what" and "why". Now that many practitioners, learning institutions and professional organizations have taken up the call, ACADIA must restate its mission, if it wishes to remain “distinct”. This does not mean that the work of ACADIA is complete. Much remains to be done and much more needs to be improved. ACADIA’s Mission Statement places particular focus on “education and the software, hardware and pedagogy involved in education.” And “(t)he organization is also committed to the research and development of computer aides that enhance design creativity, and that aim at contributing to the construction of humane physical environments.” These are the areas that continue to evolve, grow and provide for ACADIA’s continued relevance. The ACADIA 2002 conference theme reflects the state of digital technology’s application to the discipline, as much as it refers to ACADIA’s future. With the general acceptance of digital technology and CAAD, we have arrived at a place where the work of great interest and relevance lies in the space between what is digital and what is analog. The environments of real space and cyberspace have in a very short time become so intertwined that the space between real and virtual (not to be confused with reality and fantasy) is becoming indistinguishable. You cannot eat, travel, use public utilities, bank, shop, vacation or recreate without at the very least coming into contact with or passing through information space. The landscape between these two environments has become a cultural phenomenon for those societies with access to the Internet and information networks. And while the computer and World Wide Web have empowered individuals, the collective impact of the technology holds all the potential and problems that similarly emerged in other technology induced landscapes. Consider this last point in the context of ACADIA’s stated mission to “enhance design creativity while contributing to the construction of humane physical environments.” And you can see why many of the 260 initial submissions to this conference were in the area of design artifacts and design methodology, providing evidence that ACADIA’s mission remains relevant and in accord with the trends of research and professional creative activity.

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.

source	Proceedings of ITC@EDU 1st International Workshop on Construction Information Technology in Education, Portoroz, Slovenia, 12-13 September 2002
summary	We are developing a multimedia learning environment to support group work and discourse. It aims to offer the student the means and tools to organize his or her learning activities in cooperation with oth-ers. The focus is on information and document management, presentation and publication, communication and discourse, and cooperation and group work. The design of this environment is considered in relationship to an educational process in which the student becomes familiar with the use of ICT for supporting communi-cation and cooperation. We believe that such an environment plays a vital role in the application of e-learning to the design context, and that it will facilitate the initiation of networks or working groups that serve as vir-tual centers of knowledge and experimentation.

title	Knowledge Sharing for Collaborative Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	This paper presents the preliminary results of a research project that aims to develop and apply Design Knowledge Servers (DesKs) in the building and construction industry. The paper starts with a view on where the development of computer application in design and construction might be heading. It briefly looks at the current situation concerning information modelling for design support and compares two alternative ways of developing standards in this area. After this sketch of its context, the DesKs project is introduced and its objectives, characteristics, implementations issues, and application scenarios are discussed. The paper concludes with a preview of the next steps we will attempt to take and with an explanation of why it all takes so long.

title	Dynamic Knowledge Map: Reusing Experts’ Tacit Knowledge in the AEC Industry

summary	Much knowledge in the Architecture, Engineering and Construction (AEC) industry is experience-basedand tacit. Nevertheless, the typical strategy for knowledge management is focused on computer-basedapproaches for capturing and disseminating explicit knowledge. AEC firms have been successful atcollecting and storing explicit information in enterprise databases, but they are poor at knowledgeretrieval and exchange. Consequently, AEC professionals find it difficult to reuse core experts’knowledge for highly knowledge-intensive AEC activities. This situation calls for a method fordisseminating tacit knowledge from experts’ brains to achieve higher quality AEC projects.The primary purpose of this paper is to set a theoretical foundation for clarifying the contribution ofexperts’ tacit knowledge in the AEC industry. The secondary purpose is to describe the concept forprototype software, Dynamic Knowledge Map, that can assist in the reuse of experts’ tacit knowledge.Dynamic Knowledge Map is a Web-based knowledge navigator that searches for experts and facilitatescommunication with those experts by using internet technology. Higher performance levels theoreticallycan be achieved while accelerating the knowledge transfer processes. Future research will test thesuitability of Dynamic Knowledge Map for tacit knowledge utilization in AEC organizations.

title	From CAD to IAD: A Working Model of the Internet-based Engineering Consulting in Architecture
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 073-80
doi	https://doi.org/10.52842/conf.caadria.2002.073
summary	Information technology has become so powerful that what is conventionally called CAD might evolve into iAD (Internet Aided Design) in the near future (Zhou 2000). For Internet applications in the AEC industry, most of the efforts and success have been concentrated on project management and collaboration, while in the design and engineering consulting area, limited progress has been made. During the period of Internet development, the nature of the fragmentation of the AEC industry has not been changed. Based on previous research of surveys of development of Internet applications in the AEC industry (Zhou 2001), and the study of information technology both available today and in the near future, we propose a general abstracted model of an Internet-based consulting system by integrating a variety of disciplines and functions of design and construction processes. This model will cover a range of design phases, such as, information gathering, automatic remote consultation, specific problem solving, and collaboration. Finally, in future follow up research, we will apply the proposed model to steel construction in architectural design, and develop a prototype simulation by selecting one type of structural system.
