  abstract  = {Individual views on a building product of people involved in the design process imply different models for planning and calculation. In order to interpret these geometrical, topological and semantical data of a building model we identify a structural component graph, a graph of room faces, a room graph and a relational object graph as aids and we explain algorithms to derive these relations. The application of the technique presented is demonstrated by the analysis and discretization of a sample model in the scope of building energy simulation.},

  abstract  = {The goal of the research is the development of a computer system to plan, simulate and visualize erection processes in construction. In the research construction cranes are treated as robots with predefined degrees of freedom and crane-specific motion planning techniques are developed to generate time-optimized and collision-free paths for each piece to be erected in the project. Using inverse kinematics and structural dynamics simulation, the computer system then computes the crane motions and velocities necessary to achieve the previously calculated paths. The main benefits of the research are the accurate planning and scheduling of crane operations leading to optimization of crane usage and project schedules, as well as improving overall crane safety in the project. This research is aimed at the development of systems that will allow computer-assisted erection of civil infrastructure and ultimately to achieve fully-automated erection processes using robotic cranes...},

  abstract  = {Der architektonische Raum wird als ein Medium der Kommunikation im Kontext der >neuen< Medien begriffen, aus der Erkenntnis, dass er schon immer ein Medium war und aus einer komplexen Medienstruktur in Abh{\"a}ngigkeit von anderen Medien besteht. Im Prozess von Handlung und Kommunikation ist der architektonische Raum das Medium, das r{\"a}umliche N{\"a}he von Individuen {\"u}ber alle Sinne und das Bewusstsein gleichzeitig intensiv erm{\"o}glicht. Der architektonische Raum als immersives Kommunikationsmedium erreicht im Zeitalter der >neuen< Medien eine neue Dimension, indem mehr und andere Wirklichkeitsalternativen der Kommunikation zur Verf{\"u}gung stehen. N. Luhmann folgend, wird die Architektur aus der Sicht der Form/Medium-Differenz systemtheoretisch als strukturierter M{\"o}glichkeitsraum betrachtet. Der Raum ist das Medium f{\"u}r Formen des architektonischen Raumes, in dem Architektur {\"u}berhaupt erst wirksam wird. Umgekehrt sind die Formen des architektonischen Raumes Medien f{\"u}r die Wahrnehmung einer Vielzahl von r{\"a}umlichen Wirklichkeiten. Eine Fassade aus Stein oder Glas ist gebaute Form und kann als Medium Information kommunizieren. Medien werden ihrer Bestimmung um so besser gerecht, je mehr sie sich der Aufmerksamkeit entziehen und wie transparente Fenster hinter der Oberfl{\"a}che der sinnlichen Wahrnehmung zur{\"u}cktreten. Als >unwahrnehmbares< Medium ist der architektonische Raum damit eine hintergr{\"u}ndige >Wirkungsmacht<, eine B{\"u}hne f{\"u}r die Entfaltung von Wirkung, Atmosph{\"a}re und Bewegung. Seine physische Wirklichkeit war schon immer durch virtuelle Wirklichkeiten oder Realit{\"a}ten entgrenzt, die durch Techniken und Technologien der Simulation als k{\"u}nstliche Welten wahrnehmbar und kommunizierbar werden. Dies kann an tradierten Beispielen der gotischen Kathedrale, dem Panorama, den panoptischen R{\"a}umen, dem Theater, Kino oder den kontinuierlichen R{\"a}umen von der Moderne bis heute aufgezeigt weren. Virtuelle R{\"a}ume gotischer Glasbilder oder barocker Decken- und Wandbilder im Medium des architektonischen Raumes sind uns gel{\"a}ufig. Die Immersion, das Eintauchen in diese virtuellen Wirklichkeitssp{\"a}ren l{\"o}st die Wahrnehmung der eigenen k{\"o}rperlichen Pr{\"a}senz in ihnen aus. Das Potential des virtuellen Raumes der Architektur besteht im Vergleich zu anderen virtuellen Realit{\"a}ten von Text, Bild oder digitalen Medien in seiner Gebundenheit an die physische, r{\"a}umliche Reizstruktur, der er die Eindringlichkeit und Komplexit{\"a}t seiner Wirkung verdankt. Es werden unterschiedliche Wechselwirkungen und gemeinsame Entwicklungen von zeitgen{\"o}ssischen Beispielen der Architektur mit den >neuen< Medien aufgezeigt. In der »sensitiven Wand« wird die physische Raumgrenze durch die Integration neuer Techniken und Technologien digitaler, elektronischer Medien etwas extrem Flexibles und Formbares in Interaktion mit dem Benutzer. Der H2O Pavillon (Oosterhuis und NOX, 1997) ist ein Beispiel daf{\"u}r. Der ausgepr{\"a}gt polysensorische Immersionsraum steht f{\"u}r die Einheit von digitaler und architektonischer Simulation. Die metaphorische Welt von H{\"o}hle und Quelle des Thermalbades Vals (P.Zumthor, 1996) ist die r{\"a}umliche Reflexion auf die metaphorische Struktur virtueller R{\"a}ume der >neuen< Medien. Die simulierte Wirklichkeit in den Medien Wasser, Stein und architektonischer Raum produziert sch{\"o}pferisch den polysensorischen immersiven Zugang in die virtuellen Welten >authentischer< physischer Umgebung. Das >Sichtbare< im Medium Raum der Architektur ist ohne das >Unsichtbare< nicht zu begreifen bzw. das sinnlich Wahrnehmbare nicht ohne das Unwahrnehmbare. Das Erkennen dieser Relation von Form und Medium erm{\"o}glicht die Formulierung des neuen Begriffes des medialen Raumes der Architektur, der zur Basis f{\"u}r eine Medientheorie der Architektur wird, als Sichtweise der Entgrenzung des physischen Raumes durch den virtuellen Raum f{\"u}r die subjektive Wahrnehmung, Handlung und Kommunikation.},

  abstract  = {This study is an attempt to develop a simple simulation model that can compare the differences between automobile-oriented and transit-oriented cities, and clarify the difference between city forms by transportation modes. Following a theoretical model development, a series of simulation runs are tried. The model allocates people who commute to CBD from residential zones along a transportation corridor. As a result of many simulation analyses, it is shown that automobiles need much more traffic space in comparison with the transit as is shown by the proposed traffic space ratio both in CBD and along the corridor.},

  abstract  = {The development of 3D technologies during the last decades in many different areas, leads us towards the complete 3D representation of planet earth on a high level of detail. On the lowest level we have geographical information systems (GIS) representing the outer layer of our planet as a 3D model. In the meantime these systems do not only give a geographical model but also present additional information like ownership, infrastructure and others that might be of interest for the construction business. In future these systems will serve as basis for virtual environments for planning and simulation of construction sites. In addition to this work is done on the integration of GIS systems with 3D city models in the area of urban planning and thus integration of different levels of detail. This article presents research work on the use of 3D models in construction on the next level of detail below the level of urban planning. The 3D city model is taken as basis for the 3D model of the construction site. In this virtual nD-world a contractor can organize and plan his resources, simulate different variants of construction processes and thus find out the most effective solution for the consideration of costs and time. On the basis of former researches the authors present a new approach for cost estimation and simulation using development technologies from game software.},

  abstract  = {Current building product models explicitly represent components, attributes of components, and relationships between components. These designer-focused product models, however, do not represent many of the design conditions that are important for construction, such as component similarity, uniformity, and penetrations. Current design and construction tools offer limited support for detecting these construction-specific design conditions. This paper describes the ontology we developed using the manufacturing concept of features to represent the design conditions that are important for construction. The feature ontology provides the blueprint for the additions and changes needed to transform a standard product model into a constructionspecific product model. The ontology formalizes three classes of features, defines the attributes and functions of each feature type, and represents the relationships between features explicitly. The descriptive semantics of the ontology allows practitioners to represent their varied preferences for naming features, specifying features that result from component intersections and the similarity of components, and grouping features that affect a specific construction domain. A software prototype that implements the ontology enables practitioners to transform designer-focused product models into feature-based product models that represent the construction perspective.},

  abstract  = {Re-examination of the behaviour of structures can be necessary due to deterioration or changes in the traffic situation during their lifetime. 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.},
