  abstract  = {The uniqueness and the long life cycle of buildings imply a dynamically modifiable building model. The technological foundation for the management of digital building models, a dynamic model management system (MMS), developed by our research group, allows to explicitly access and to modify the object model of the stored planning data. In this paper, the integration of constraints in digital building models will be shown. Constraints are conditions, which apply to the instances of domain model classes, and are defined by the user at runtime of the information system. For the expression of constraints, the Constraint Modelling Language (CML) has been developed and will be described in this paper. CML is a powerful, intuitively usable object-oriented language, which allows the expression of constraints at a high semantic level. A constrained-enabled MMS can verify, whether an instance fulfils the applying constraints. To ensure flexibility, the evaluation of constraints is not implicitly performed by the systems, but explicitly initiated by the user. A classification of constraint types and example usage scenarios are given.},

  abstract  = {The rise of concurrent engineering in construction demands early team formation and constant communication throughout the project life cycle, but educational models in architecture, engineering and construction have been slow to adjust to this shift in project organization. Most students in these fields spend the majority of their college years working on individual projects that do not build teamwork or communication skills. Collaborative Design Processes (CDP) is a capstone design course where students from the University of Illinois at Urbana-Champaign and the University of Florida learn methods of collaborative design enhanced by the use of information technology. Students work in multidisciplinary teams to collaborate from remote locations via the Internet on the design of a facility. An innovation of this course compared to previous efforts is that students also develop process designs for the integration of technology into the work of multidisciplinary design teams. The course thus combines both active and reflective learning about collaborative design and methods. The course is designed to provide students the experience, tools, and methods needed to improve design processes and better integrate the use of technology into AEC industry work practices. This paper describes the goals, outcomes and significance of this new, interdisciplinary course for distributed AEC education. Differences from existing efforts and lessons learned to promote collaborative practices are discussed. Principal conclusions are that the course presents effective pedagogy to promote collaborative design methods, but faces challenges in both technology and in traditional intra-disciplinary training of students.},

  abstract  = {The management of resources is an essential task in each construction company. Today, ERP systems and e-Business systems are available to assist construction companies to efficiently organise the allocation of their personnel and equipment within the company, but they cannot provide the company with the idle resources for every single task that has to be performed during a construction project. Therefore, companies should have an alternative solution to better exploit expensive resources and compensate their fixed costs, but also have them available at the right time for their own business activities. This paper outlines the approach taken by the EU funded project "e-Sharing" (IST-2001-33325) to support resource management between construction companies. It will describe requirements for the management of construction resources, its core features, and the integration approach. Therefore, we will outline the approach of an integrated resource type model supporting the management and classification of construction equipment, construction tasks and qualification profiles. The development is based on a cross-domain analysis and evaluation of existing models. ...},

  abstract  = {The AEC industry is conscious of the potentials arising from the usage of mobile computer systems to increase productivity by streamlining their business processes. Discussions are no longer on whether or not to use a mobile computer solution, but rather, on how it should be used. However, the implantation process of this new technology in Architecture, Engineering and Construction (AEC) and Facility Management (FM) practise is very slow and should be improved. One way to encourage and ease the usage of mobile computer systems in AEC is a more process-oriented usability and context appropriateness of mobile computer solutions. Context-sensitivity is defined as a crucial feature to be taken into account for further research in the area of Mobile Computing. Context-sensitive, mobile IT-solutions depend on two features: (1) flexible definitions of (construction) processes describing the context and (2) tools for flexible, multi-dimensional information management representing the context. It is on this premise that the authors propose the n-dimensional data management approach for the implementation of mobile computing solutions. In this paper, we analyse working scenarios in the AEC and FM sector, defining context aspects which are transformed and formalized as dimension hierarchies of the envisaged context model.},

  abstract  = {The promise of lower costs for sensors that can be used for construction inspection means that inspectors will continue to have new choices to consider in creating inspection plans. However, these emerging inspection methods can require different activities, resources, and decisions such that it can be difficult to compare the emerging methods with other methods that satisfy the same inspection needs. Furthermore, the context in which inspection is performed can significantly influence how well certain inspection methods are suited for a given set of goals for inspection. Context information, such as weather, security, and the regulatory environment, can be used to understand what information about a component should be collected and how an inspection should be performed. The research described in this paper is aimed at developing an approach for comparing and selecting inspection plans. This approach consists of (1) refinement of given goals for inspection, if necessary, in order to address any additional information needs due to a given context and in order to reach a level of detail that can be addressed by an inspection activity; (2) development of constraints to describe how an inspection should be achieved; (3) matching of goals to available inspection methods, and generation of activities and resource plans in order to address the goals; and (4) selection of an inspection plan from among the possible plans that have been identified. The authors illustrate this approach with observations made at a local construction site.},

Collaboration amongst team members seperated in time and location is of particular importance. Two broad themes can be recognized in research pertaining to distributed collaboration. One theme focusses on the technical and technological aspects of distributed work, while the other emphasises human aspects thereof. The case of finite element structural analysis in a distributed collaboratory is examined in this paper. An approach is taken which has its roots in human aspects of the structural analysis task. Based on experience of how structural engineers currently approach and execute this task while utilising standard software designed for use on local workstations only, criteria are stated for a software architechture that could support collaborative structural analysis. Aspects of a pilot application and the results of qualitative performance measurements are discussed.},

  abstract  = {The planning of projects in building engineering is a complex process which is characterized by a dynamical composition and many modifications during the definition and execution time of processes. For a computer-aided and network-based cooperation a formal description of the planning process is necessary. In the research project "Relational Process Modelling in Cooperative Building Planning" a process model is described by three parts: an organizational structure with participants, a building structure with states and a process structure with activities. This research project is part of the priority program 1103 "Network-Based Cooperative Planning Processes in Structural Engineering" promoted by the German Research Foundation (DFG). Planning processes in civil engineering can be described by workflow graphs. The process structure describes the logical planning process and can be formally defined by a bipartite graph. This structure consists of activities, transitions and relationships between activities and transitions. In order to minimize errors at execution time of a planning process a consistent and structurally correct process model must be guaranteed. This contribution considers the concept and the algorithms for checking the consistency and the correctness of the process structure.},

  abstract  = {Information science researchers and developers have spent many years addressing the problem of retrieving the exact information needed and using it for analysis purposes. In informationseeking dialogues, the user, i.e. construction project manager or supplier, often asks questions about specific aspects of the tasks they want to perform. But most of the time it is difficult for the software systems to unambiguously understand their overall intentions. The existence of information tunnels (Tannenbaum 2002) aggravates this phenomenon. This study includes a detailed case study of the material management process in the construction industry. Based on this case study, the structure of a formal user model for information retrieval in construction management is proposed. This prototype user model will be incorporated into the system design for construction information management and retrieval. This information retrieval system is a user-centered product based on the development of a user configurable visitor mechanism for managing and retrieving project information without worrying too much about the underlying data structure of the database system. An executable UML model combined with OODB is used to reduce the ambiguity in the user's intentions and to achieve user satisfaction.},

  abstract  = {At the start of the conceptual design process, designers start to give tangible form to their thoughts by sketching. This helps with reasoning and communicates ideas to other members of the team. Sketches are gradually worked up into more formal drawings which are then passed to the other stages of the design process. There are however some problems with basing early ideas on sketching. For example, due to their ad-hoc nature, sketches tend only to be diagrammatic representations and so designers cannot be sure that their ideas are feasible and what is being proposed meets the constraints described in the client brief. This can result in designers wasting time working up ideas which prove to be unsuitable. Also the process of constraint checking is complex and time consuming and so designers tend limit their search of possible options and instead choose satisfying rather than good solutions. This paper describes the INTEGRA project which examines the role of sketching in early conceptual design and how this can be linked to other aspects of the process and particularly automated constraint checking using an IT based approach. The focus for the work is the design of framed buildings. A multi-disciplinary approach has been adopted and the work has been undertaken in close collaboration with practising designers and clients.},

Technological innovations that have been taking place are just simulating the old traditional paper workflow. Engineering information in digital form is being conveyed using traditional paper representations, which have to be interpreted by humans before the information can be used in other applications, thereby creating 'islands of information'. It can be seen that poorly implemented IT strategies are duplicating paperwork, rather than reducing or eliminating it (Crowley et al., 2000).

The application described there has a standalone component for executing the finite element method on a local workstation in the absence of network access. This application is comparable to current, local workstation based finite element packages. However, it differs fundamentally from standard packages since the application itself, and its objects, are adapted to support distributed execution of the analysis task. Basic aspects of an object-oriented framework for the development of applications which can be used in similar distributed collaboratories are described in this paper. An important feature of this framework is its application-centred design. This means that an application can contain any number of engineering models, where the models are formed by the collection of objects according to semantic views within the application. This is achieved through very flexible classes Application and Model, which are described in detail. The advantages of the application-centred design approach is demonstrated with reference to the design of steel structures, where the finite element analysis model, member design model and connection design model interact to provide the required functionality.},

Ideally, the domain expert alone can adjust the wearable computer system to achieve this fit without having to consult IT experts. In this paper, we describe a model that helps in transferring existing design knowledge from non-AEC domains to new projects in the construction area. The base for this is a model and a methodology that describes the usage scenarios of said computer systems in an application-neutral and domain-independent way. Thus, the actual design information and experience will be transferable between different applications and domains.},

The proposed technique uses a coarse-grain approach to model development whereby each element represents a complete building component such as a wall, internal space, or floor. The thermal behavior of each coarse-grain element is captured using empirical modeling techniques such as artificial neural networks (ANNs). The main advantages of the approach compared to conventional simulation methods are: (a) simplified model construction for the end-user; (b) simplified model reconfiguration; (c) significantly faster simulation runs (orders of magnitude faster for two and three-dimensional models); and (d) potentially more accurate results. The paper demonstrates the viability of the approach through a number of experiments with a model of a composite wall. The approach is shown to be able to sustain highly accurate longterm simulation runs, if the coarse-grain modeling elements are implemented as ANNs. In contrast, an implementation of the coarse-grain elements using a linear model is shown to function inaccurately and erratically. The paper concludes with an identification of on-going work and future areas for development of the technique.},

The influence of the interaction between a graphical user interface and a data base for the development of an civil engineering application is investigated in this paper. A graphic application for the linear elastic analysis of plane frames, which was previously developed with standard tools of the Java platform, is compared to a redesigned implementation using a generalized data base for persistent objects. The investigation leads to the following results : - A strict distinction between persistent and transient objects influences the class structure of an application, in particular the class structure of a graphical user interface. - The structure of an application depends on the logic for updating of references to persistent and transient graphical objects after an application is read from a file. - The complexity of the reference management can usually be handled better by just in time referencing associated with String - identifiers rather than by automated referencing associated with Name - identifiers.},

The computer-aided simulation of suspension models is used to derive structurally favourable forms for domes and arches subject to compression load, based upon the input of simple architectonic parameters. Irregular plans, three-dimensional topography, a choice different kinds of shell lattice structures and the desired height of the dome are examples of design parameters which can be used to modify the architectural design. The provision of data export formats for structural dimensioning and visualisation software enables engineers and planners to use the data in future planning and to communicate the design to the client.},

The Finite Element Method (FEM) is widely used in order to accomplish numerical analysis. Considering the development of computer performance, more detailed FEM models can be analyzed, even on site, with mobile computers. To compensate the increasing amount of data needed for the model input, measures need to be taken to save time, by distributing the work. In order to provide consistency to the model, fedback data must be checked upon reception. A local wireless computer network of ultra-portable devices linked together with a computer can provide the coordination necessary for efficient parallel working. Based on a digital model consisting of all data gathered, structural modelling and numerical analysis are performed automatically. Thus, the user is released from the work that can be automatized and the time needed for the overall analysis of a structure is decreased.},

At this interface, the complete data set of planning and execution gets lost.

This is why a new software generation is demanded, which continuously covers the entire workflow process from the planning phase to the demolition of a building. New data concepts have to be developed, which allow bringing work items for construction together with work items for real estate use.},

Often, information that is observed on a construction site needs to be integrated into electronic documents or project control systems. In the future, we expect integrated product and process models to be the medium for storing and handling construction project management information. Even though mobile computing devices today are already capable of storing and handling such integrated product and process data models, the user interaction with such large and complex models is difficult and not adequately addressed in the existing research. In this paper, we introduce a system that supports project management tasks on construction sites effectively and efficiently by making integrated product and process models accessible. In order to effectively and efficiently enter or access information, site superintendents need visual representations of the project data that are flexible with respect to the level of detail, the decomposition structure, and the type of visual representation. Based on this understanding of the information and data collection needs, we developed the navigational model framework and the application Site Data Collection System (SiDaCoS), which implements that framework. The navigational model framework allows site superintendents to create customized representations of information contained in a product and process model that correspond to their data access and data collection needs on site.},

  abstract  = {A market analysis conducted by Gartner Dataquest in August 2001 has shown the typical characteristics of the AEC design process. High volatility in membership of AEC design groups and members dispersed over several external offices is the common collaboration scenario. Membership is most times short lived, compared to the overall duration of the process. A technical solution has to take that into account by making joining and leaving a collaborative work group very easy. The modelling of roles of collaboration between group members must be based on a commonly understood principle like the publisher / subscriber model, where the individual that is responsible for the distribution of vital information is clear. Security issues and trust in the confidentiality of the system is a central concern for the acceptance of the system. Therefore, keeping the subset of data that will be published under the absolute control of the publisher is a must. This is not the case with server-based scenarios, sometimes even due to psychological reasons. A loosely bound Peer-to-Peer network offers advantages over a server-based solution, because of less administrative overhead and simple installation procedures. In a peer-to-peer environment, a publish/subscribe role model can be more easily implemented. The publish/subscribe model matches the way AEC processes are modelled in real world scenarios today, where legal proof of information exchange between external offices is of high importance. Workflow management systems for small to midsize companies of the AEC industry may adopt the peer-to-peer approach to collaboration in the future. Further investigations are being made on the research level (WINDS) by integrating the viewer and redlining application Collaborate! into a collaborative environment.},

  abstract  = {The design of building projects involves several types of resources such as architects, structural engineers, mechanical engineers, electrical engineers, and draftsmen, among others. For design firms to stay in business in this very competitive market, they need to manage their resources in a way that improves productivity and cost effectiveness. This task, however, is not simple and requires thorough analysis of process-level operations, resource use, and productivity. Typically, these operational aspects are the responsibility of the design office manager who assigns available resources to the different design projects to save time and lower design expenses. It is noted that limited studies have been carried out in the literature to model overall organizational operations and behavioral aspects, particularly in firms specialized in the design of building projects. In an effort to simplify the modeling process, a simplified modeling and simulation tool is used in this research. A simulation model representing an actual design office was developed assuming that the office performs designs for small, medium, and large size building projects. The developed model was used to simulate several alternatives and examine various resource assignment strategies. The simulation was conducted over ten years and the resulting productivity and income was measured.},

  abstract  = {Structural engineering projects are increasingly organized in networked cooperations due to a permanently enlarged competition pressure and a high degree of complexity while performing the concurrent design activities. Software that intends to support such collaborative structural design processes implicates enormous requirements. In the course of our common research work, we analyzed the pros and cons of the application of both the peer-to-peer (University of Bonn) and multiagent architecture style (University of Bochum) within the field of collaborative structural design. In this paper, we join the benefits of both architecture styles in an integrated conceptual approach. We demonstrate the surplus value of the integrated multiagent-peer-to-peer approach by means of an example scenario in which several structural engineers are co-operatively designing the basic structural elements of an arched bridge, applying heterogeneous CAD systems.},

It is evident that introducing high-level CAD design and detailing will improve the planning process in developing countries. Successful utilization of applied information technology for the planning process, however, depends on the user-interface of individual software. Therefore, to open the great opportunity embedded in CAD software for clients globally, the language and character-set barrier of traditional user-interfaces must be overcome. A proposal for a research program is given here to address such issue in favour of global civil engineering.},

  abstract  = {During the establishing of fundamentals in a building project a huge amount of influence factors and boundary conditions have to be investigated in order to provide the prerequisites for further planning processes. These investigative tasks are often related with a great effort concerning time and money, because there are no standardized workflows and interfaces which provide an efficient access to the necessary information related to a specific construction site. Within the fundamental investigation human and natural circumstances have to be taken into account. Thus, in this project two examples have been chosen in order to demonstrate the holistic approach for an integration and provision of georeferenced information. The developed internet-site http://www.grundlagenermittlung.de has been designed to support architects and civil engineers in early planning phases of a building project efficiently. It offers web-based services based on dynamic interfaces for a flexible search and collection of information concerning the building site. Therefore, a central Metadatabase-Server for Description, Discovery and Integration has been established which enables a registration of georeferenced services and the redirection of incoming requests to other, distributed data pools. Using this Yellow-Page concept in combination with the underlying meta-data based on the ISO 19115 standard an efficient investigation of geographical and environmental information becomes possible.},

Given that most of the planned data are already digitally available, as-built data remains on paper forms. Information technology developments are opening new ways to digitize construction field data in order to develop intelligent tools for construction management allowing design engineers to update as-planned data. 3D Laser scanning, digital close-range photogrammetry and mobile computing are among the promising data collection technologies, which are auspicious to create new opportunities to develop advanced construction management and engineering tools.

The structures considered are described in terms of an equivalent Finite Element model, the stochastic properties, like e.g. the scatter of the material behavior or the incoming load, are represented using suitable random variables. Within the software framework, a Client-Server-Architecture has been implemented, employing the middleware CORBA for the communication between the distributed modules. The analysis server offers the possibility to compute failure probabilities for stochastically defined structures. Therefore, several different approximation (FORM, SORM) and simulation methods (Monte Carlo Simulation and Importance Sampling) have been implemented. This paper closes in showing several examples computed on the analysis server.},

In this article the basics of an object oriented higher order finite element system especially tailored to the use in structural optimization is presented.

Given the nature of architectural constraints, user-model interactivity is devised as the most suitable computer methodology for driving the structural synthesis process. Taking advantage of the hierarchical organization of the structural system, this research proposes a top-down approach for structural synthesis. Through hierarchical refinement, the approach lends itself to the synthesis of global and local structural solutions. The components required for implementing the proposed methodology are briefly described. The main components have been incorporated in a proof-of-concept prototype that is being tested and validated with actual buildings.},

  abstract  = {This paper presents a specific modeling technique that is focused on preparing planning processes in civil engineering. Planning processes in civil engineering are characterized by some peculiarities so that the sequence of planning tasks needs to be determined for each planning project. Neither the use of optimized partial processes nor the use of lower detailed and optimized processes guarantee an optimal overall planning process. The modeling technique considers these peculiarities. In a first step, it is focused on the logic of the planning process. Algorithms based on the graph theory determine that logic. This approach ensures consistency and logical correctness of the description of a planning process at the early beginning in its preparation phase. Sets of data - the products of engineers like technical drawings, technical models, reports, or specifications - form the core of the presented modeling technique. The production of these sets of data requires time and money. This is expressed by a specific weighting of each set of data in the presented modeling technique. The introduction of these weights allows an efficient progress measurement and controlling of a planning project. For this purpose, a link between the modeling technique used in the preparation phase and the execution phase is necessary so that target and actual values are available for controlling purposes. The present paper covers the description of this link. An example is given to illustrate the use of the modeling technique for planning processes in civil engineering projects.},

These obstacles can be either related to use of new technology or to organization culture. The paper discusses e-mail as a medium of communication with the media richness framework (Fulk \& Boyd 1991) based on the interviews done with the participants of construction projects. We found out that the emails were used in both rich way and not so rich way. Obstacles of rich use of IT communication were partly technical and partly psychological. Technology acceptance model (TAM) is used to study the actual use of emails in communication. Obstacles of the use of emails were mostly individual differences like the skills to use the system or external variables like they did not have proper software to open the attachments. Also people talked about information overload. Emails often push too much information. Keywords: IT tools, Communication, Knowledge management, Construction},

Such a process-model for engineering purposes has to satisfy several needs, e.g., the consideration of planning and building alternatives, dynamic changes of the model during execution of the project and the linkage to further technical objects like costs, building structure, specifications and documentmanagement. Furthermore, the scheduling of the project can be done within the process-model and can be visualized as a Gantt-diagram. ...},

Even with the increasing integration of model-based systems with project information spaces, a large percentage of the information exchange will further on rely on isolated and rather poorly structured text documents. In this paper we propose an approach enabling the use of product model data as a primary source of engineering knowledge to support information externalisation from relevant construction documents, to provide for domain-specific information retrieval, and to help in re-organising and re-contextualising documents in accordance to the user's discipline-specific tasks and information needs. Suggested is a retrieval and mining framework combining methods for analysing text documents, filtering product models and reasoning on Bayesian networks to explicitly represent the content of text repositories in personalisable semantic content networks. We describe the proposed basic network that can be realised on short-term using minimal product model information as well as various extensions towards a full-fledged added value integration of document-based and model-based information.},

  abstract  = {Advances in construction data analysis techniques have provided useful tools to discover explicit knowledge on historical databases supporting project managers' decision making. However, in many situations, historical data are extracted and preprocessed for knowledge discovery based on time-consuming and problem-specific data preparation solutions, which often results in inefficiencies and inconsistencies. To overcome the problem, we are working on the development of a new data fusion methodology, which is designed to provide timely and consistent access to historical data for efficient and effective management knowledge discovery. The methodology is intended to be a new bridge between historical databases and data analysis techniques, which shields project managers from complex data preparation solutions, and enables them to use discovered knowledge for decision making more conveniently. This paper briefly describes the motivation, the background and the initial results of the ongoing research.},

The data-mining of multi-objective COGA (moCOGA) output further defines these regions through the application of clustering algorithms, data reduction and variable attribute relevance analyses. A number of visual representations of the COGA output projected onto both variable and objective space are presented. The multi-objective output of the COGA is compared to output from a Strength Pareto Evolutionary Algorithm (SPEA-II) to illustrate the manner in which moCOGAs can generate good approximations to Pareto frontiers.},

The main advantages are the arrangement of the tasks of a project in a clear, easily readable form and the calculation of valuable information like critical paths. The main disadvantage on the other hand is the inflexibility of the model caused by the modeling paradigms. Small changes of the modeled information strongly influence the whole model and lead to the need to change many more details in the plan. In this article an approach is introduced allowing the creation of more flexible schedules. It aims towards a more robust model that lowers the need to change more than a few information while being able to calculate the important propositions of the known models and leading to further valuable conclusions.},

  abstract  = {This paper describes a couple of new truss structures based on fractal geometry. One is the famous Sierpinski Gasket and another is a fractal triangle derived by means of applying a process forming leaves of a cedar tree using M. F. Barnsley's contraction mapping theory. Therefore a pair of x-y coordinates of an arbitrary nodal point on the structures are generated easily if IFS(Iterated Function System) codes and a scale of them are specified. Structural members are defined similarly. Thus data for frame analysis can be generated automatically, which is significant if the objective structure has complex configuration. Next analytical results under vertical and wind loadings in Japanese Building Code are shown. Here members are assumed to be timber and to have cross section of 15cm×15cm. Finally authors conclude that geometrically new truss structures were developed and automatic data generation for frame analysis was attained using IFS. Analytical results show they contribute to saving material when compared it with King-post truss.},

In this paper, we present an approach that focuses on matching data models in a specific domain. The approach combines a basic model matching approach and a version matching approach to deduce new matching rules to enable data transfer between two evolving data models.},

The objects contain attributes and methods. Properties of the objects are stored in the attributes. Algorithms which the objects perform are implemented in the methods of the objects. If objects are modified by a user, the consistency of data in the base is destroyed. The data base must be modified in an update to restore its consistency. The sequence of the update operations is not arbitrary, but is governed by dependence between the objects. The situation can be described mathematically with graph theory. The available algorithms for the determination of the update sequence are not suitable when the data base is large. A new update algorithm for large data bases has been developed and is presented in this paper.},

This research introduces a nouvelle approach, by using Artificial Neural Network (ANN) for accurately evaluating the shear cracking angle of reinforced and prestressed concrete beams.

Modern indentation machines have the capability to continuously monitor load and displacement to high precision and accuracy. In recent years, research interests have focussed on methods to extract material properties from indentation load-displacement curves. Analytical methods to interpret the indentation load-displacement curves are difficult to formulate due to material and geometric nonlinearities as well as complex contact interactions. In the present study, an artificial neural network model was constructed for interpretation of indentation load-displacement curves. Large strain-large deformation finite element analyses were first carried out to simulate indentation experiments. The data from finite element analyses were then used to train the artificial neural network model. The artificial neural network model was able to accurately determine the material properties when presented with load-displacement curves which were not used in the training process. The proposed artificial neural network model is robust and directly relates the characteristics of the indentation loaddisplacement curve to the elasto-plastic material properties.},

The functionality provided by an information module should cover several levels of information provision ranging from 'simple retrieval' of relevant information to the analysis and assessment of stored information with regard to particular question sets. Through the provision of basic functionality at an elementary level and the ability to extend this using plug-ins, the system concept of an open extendable system is upheld. Using this modular approach, different levels of information provision can be provided as required during the planning process.},

These requirements motivate the use of the Common Object Request Broker Architecture (CORBA), which offers sufficient advantage than communication within simple abstraction. However, set up highly available applications with CORBA is hard. Neither control modeling software nor building performance environments have simple interface with CORBA objects. Therefore, this paper describes an architectural solution to distributed control and building performance software tools with CORBA objects. Then, it explains how much the developement of CORBA based distributed building control simulation applications is difficult. The paper finishes by giving some recommendations.},

In order to perform mass calculation, damage mapping or a recalculation of the structure these drawings of the building under consideration have to be analysed manually by the engineer. This is a very time-consuming job. In order to close this gap between drawings of an existing building and a digital product model an approach is presented in this paper to digitise a drawing, to build up geometric and topologic models and to recognise construction parts of the building. Finally all recognised parts are transformed into a three-dimensional geometric model which provides all necessary geometric information for the product model. During this import process the semantics of a ground floor plan has to be converted into a 3D-model.},

Firm performance is a composite score of several metrics of performance: schedule performance, cost performance, customer satisfaction, safety performance, and profit. No relationship is found between IT utilization and customer satisfaction, safety, or profit, although this may be due to limitations of the study given strong correlations between IT utilization and cost and schedule performnance. The empirical evidence of positive association between performance and IT use provided by this research is significant to both construction practice and research literature. This evidence should encourage firms to adopt and invest in IT tools.},

There are often multiple documents that need to be consulted and satisfied; however it is a difficult task to locate all of the relevant provisions. In addition, sections dealing with the same or similar conceptual ideas sometimes lay down conflicting requirements. We propose a framework for regulation representation, analysis and comparison with emphasis on the extraction of similarities between provisions. We focus on accessibility regulations, whose intent is to provide the same or equivalent access to a building and its facilities for disabled persons. An XML regulatory repository is developed to extract structural as well as non-structural features from government regulations to help user understanding and computational analysis. A similarity analysis is performed between different sources of regulations. In order to achieve a better comparison between provisions, we employ a combination of feature matching and structural analysis. Results are shown on comparisons between American and European codes, as well as on the domain of electronic-rulemaking.},

  abstract  = {Construction is a conservative industry that over the last twenty ye ars has experienced drastic changes in the way that interdisciplinary teams interact to design and execute a project. In this article we offer a general overview of how the main participants cooperate in the different phases of a construction project, and which are some of the main areas for communication improvement. We also explore the communication tools used in the exchange of information, and identify the main causes of information breakdown. The general framework of this study is of application to both standard and green projects. At the end of the article we discuss the peculiarities of green buildings. Our goal is to offer a series of industry insights derived from the perspective of a general contractor aimed at identifying the areas where contributions in computing and information exchange could have a greater impact on the successful completion of a project.},

  abstract  = {An important feature of the 2003 SARS outbreak in Canada, Singapore, and Hong Kong was that many health care workers (HCWs) developed SARS after caring for patients with SARS. This has been ascribed to inadequate or ineffective patient isolation. However, it is difficult for dense cities to provide sufficient isolation facilities within a short period of time. This has raised concerns from the public for new strategies in the planning and design of isolation facilities. Considering that SARS or other infectious diseases could seriously damage our society's development, isolation facilities that could be rapidly and economically constructed with appropriate environmental controls are essential. For this reason, the design team of the Department of Architecture collaborated with a special task force from the Faculty of Medicine, who are the frontline medical officers treating the SARS patients, to design Rapidly Assembled Isolation Patient Wards. Both architecture and medicine are well established disciplines, but they have little in common in terms of the mode of knowledge construction and practice. This induced much intellectual exploration and research interest in conducting this study. The process has provided an important reference for cross disciplinary studies between the architectural and medical domains.},

  abstract  = {Current methods for site modeling employs expensive laser range scanners that produce dense point clouds which require hours or days of post-processing to arrive at a finished model. While these methods produce very detailed models of the scanned scene, useful for obtaining as-built drawings of existing structures, the associated computational time burden precludes the methods from being used onsite for real-time decision-making. Moreover, in many project life-cycle applications, detailed models of objects are not needed. Results of earlier research conducted by the authors demonstrated novel, highly economical methods that reduce data acquisition time and the need for computationally intensive processing. These methods enable complete local area modeling in the order of a minute, and with sufficient accuracy for applications such as advanced equipment control, simple as-built site modeling, and real-time safety monitoring for construction equipment. This paper describes a research project that is investigating novel ways of acquiring, integrating, modeling, and analyzing project site spatial data that do not rely on dense, expensive laser scanning technology and that enable scalability and robustness for real-time, field deployment. Algorithms and methods for modeling objects of simple geometric shape (geometric primitives from a limited number of range points, as well as methods provide a foundation for further development required to address more complex site situations, especially if dynamic site information (motion of personnel and equipment). Field experiments are being conducted to establish performance parameters and validation for the proposed methods and models. Initial experimental work has demonstrated the feasibility of this approach.},

  abstract  = {For planning in existing built contexts, the building survey is the starting point for initial planning proposals, for the diagnosis and documentation of building damages, for the creation of objectives catalogues, for the detailed design of renovation and conversion measures and for ensuring fulfilment of building legislation, particularly by change of use and refitting. An examination of currently available IT-tools shows insufficient support for planning within existing contexts, most notably a deficit with regard to information capture and administration. This paper discusses the concept for a modular surveying system (basic concept, separation of geometry from semantic data, and separation into sub-systems) and the prototypical realisation of a system for the complete support of the entire building surveying process for existing buildings. The project aims to contribute to the development of a planning system for existing buildings. ...},

  abstract  = {The contribution describes the didactical integration of wireless access networks for the campus of the University of Karlsruhe in the education of architects and engineers. It focuses on the development of an interdisciplinary communication network to encourage and promote the communication and collaboration between students. The project assumes that significant learning progresses in net-based learning scenarios are based upon the synchronous and asynchronous cooperation between the students themselves. The remote cooperation across borders of disciplines makes high demands on capacity in communicating and cooperating of the involved persons as well as on the supporting tools. Therefore, the collective acquisition of knowledge and cooperation has to be trained intensively during the studies. Based on the design and project oriented cooperation platform netzentwurf.de the authors developed the tools "Jobadmin" to administrate multidisciplinary workgroups, the "Swarm Knowledge Catalogue" to collect and store knowledge and "LivingCampus", an instrument providing basic services for dynamic communication.},

Buildings with regular shapes and plane roofs are constructed into computer models by identifying of graphic elements from the digital maps of urban area to get building base plane and building heights. Buildings with irregular shapes and non-plane roofs are constructed into computer models by employment of a specific system developed by the authors. Road objects and topologies are constructed into computer models by employment of specific algorithms.

  abstract  = {The construction management has been under pressure to reduce operating costs and to improve productivity using innovative information technologe (IT) solutions conformed to structural characteristics, site conditions and past experiences. Given the growing emphasis on effectiveness and efficiency in construction projects, there is an imminent need to develop a formal procedure to select the best IT application for each proposed construction project and research and development (R\&D) project. As there are numerous factors that have to be considered in selecting appropriate IT in a given situation, decision-makers need to have multicriteria decision-making ability. To enable them to make the most appropriate decision in any situation, it is important that effective tools incorporating multicriteria decision-making techniques are available. In this paper, an Analytic Network Process (ANP) model is conducted for the selection of appropriate IT application for innovative construction management prior to construction or research. The paper concludes that the ANP is a viable and capable tool for conducting IT application selection in multicriteria decision-making environment.},

We describe and illustrate through a scenario of use an exploration framework and prototype, CoMemTM that formalizes the added value of exploration in the process of knowledge reuse. We discuss two exploration activities: (i) Breadth- Only overview exploration that assist a user to rapidly localize pockets of re-usable knowledge from the large corporate archive and (ii) Iterative breadth-depth exploration that enables a user to identify those re-usable components of the Corporate Memory that may yield design issues that were not originally considered.},

Bagging is used to improve the prediction accuracy of these two algorithms, and results are compared with the ones obtained earlier by the k-nearest neighbor (KNN) algorithm. From the conducted experiments, both the bagged regression tree and bagged model tree produce better results than not only their corresponding regression tree and model tree alone, but also the KNN with optimal value of k equal to 7. In addition, the bagged model tree yields the lowest prediction errors and a highest correlation coefficient of 0.81. It is demonstrated that it is feasible to use the bagged model tree for engineering applications in prediction problems such as estimating the remaining service life of bridge decks.},

This leads to a more flexible handling of measurement and simulation information in distributed and interdisciplinary engineering projects based on the concept of information sharing. The potential and advantages of Web-based information systems like 'Turtle' are described for one selected application example: a measurement programme dealing with the physical limnology of Lake Constance.},
