  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  = {Der Fokus des Projektes liegt auf einer besseren Unterst{\"u}tzung der kooperativen Aspekte im Bauwerksentwurf und der Anwendung von ComponentWare-Techniken in der Architektur des Entwurfssystems. Es muß festgestellt werden, daß die Kooperation der Beteiligten im Entwurfsprozeß von Bauwerken durch die heute praktizierten Datenaustauschverfahren nicht oder nur unbefriedigend unterst{\"u}tzt wird und das keine L{\"o}sung dieses Problems durch die Weiterentwicklung von filebasierten Datenaustauschformaten zu erwarten ist. Im Rahmen des Projektes wird mit einer CORBA-Umgebung f{\"u}r Smalltalk-80 ein verteilbares Objektsystem realisiert. Als Architektur des Systems wurde eine hybride Herangehensweise gew{\"a}hlt, bei der allgemeine Informationen auf einem zentralen Server verwaltet werden und die eigentlichen Projektinformationen bei Bedarf repliziert werden. Wie allgemein in GroupWare - orientierten Systemen notwendig, m{\"u}ssen effektive Mechanismen der Nebenl{\"a}ufigkeitskontrolle und zur Sperrung bestimmter Modellbereiche realisiert werden. Wichtig ist f{\"u}r kooperative Entwurfssysteme die Systemunterst{\"u}tzung der Beseitigung der Folgen von kollidierenden Entwurfsintensionen durch die Bearbeiter. Dazu werden unter anderem Remote-Pointer-Mechanismen realisiert. In Abh{\"a}ngigkeit von der Rolle eines Bearbeiters werden diesem Sichten auf des Objektmodell (Partialmodelle) zugeordnet. Es werden Mechanismen zur Autorisierung des Zugriffs auf Partialmodelle implementiert, zu diesem Zweck erfolgt eine Nutzerauthentifizierung. Beziehungen zwischen Partialmodellen werden durch eine spezielle Relation im Objektsystem abgebildet. Die Konzeption des Objektsystems lehnt sich an die PREPLAN-Philosophie an. Das impliziert die Unterst{\"u}tzung von Entwurfshandlungen sowohl in Bottom-Up- als auch in Top-Down - Richtung. Benutzer k{\"o}nnen das Objektsystem um eigene Klassen erweitern bzw. existierende Klassen modifizieren und Attribute mit Defaultwerten belegen, um das System inkrementell mit Dom{\"a}nenwissen anreichern zu k{\"o}nnen. Von großer Bedeutung f{\"u}r kooperative Entwurfssysteme sind eine Versionsverwaltung und die Bereitstellung von Undo - und Redo - Mechanismen. Es ist m{\"o}glich, multimediale Daten im Objektmodell abzulegen und diese in Abh{\"a}ngigkeit von ihrem Format wiederzugeben bzw. zu bearbeiten. Das beschriebene System befindet sich derzeit in der Implementierung.},

  abstract  = {The general motivation of this research is to develop software to support the handling of the increased complexity of architectural design. In this paper we describe a system providing general support during the whole process. Instead of only developing design tools we are also addressing the problem of the operating environment of these tools. We conclude that design tools have to be integrated in an open, modular, distributed, user friendly and efficient environment. Two major fields have to be addressed - the development of design tools and the realisation of an integrated system as their operation environment. We will briefly focus on the latter by discussing known technologies in the field of information technology and other design disciplines that can be used to realise such an environment. Regarding the first subject we have to state the need of a detailed tool specification. As a solution we suggest a strategy where the tool functions are specified on the basis of a transformation, where a hierarchical process model is mapped into specifications of different design tools realising appropriate support for all sub-processes of architectural design. Using this strategy the main steps to develop such a support system are: implementation of a framework as basis for the integrated design system decision whether the tool specification are already implemented in available tools in this case these tools can be integrated using known methods for tool coupling otherwise new design tools have to be developed according to the framework},

  abstract  = {Complex gridshell structures used in architecturally ambitious constructions remain as appealing as ever in the public realm. This paper describes the theory and approach behind the software realisation of a tool which helps in finding the affine self-weight geometry of gridshell structures. The software tool DOMEdesign supports the formal design process of lattice and grid shell structures based upon the laws of physics. 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.},

Selected aspects of the concept have been implemented and tested as prototypes. The process of step-by-step capture and representation is determined by the order in which the user experiences the building. Only the information that the user knows (can see) or can reasonably deduce is represented. In addition approaches to the flexible combination of different measuring techniques and geometric abstractions are described which are based upon geodetic computational adjustment.},

  abstract  = {Most retaining walls and box culverts built for arterial road construction are simple, and the design process of these structures is often repetitive and labor-intensive because they are so similar in structural configuration. Although some integrated design automation systems developed for retaining walls and box culverts have expedited the design process of these structures, the process of collecting and distributing the resultant engineering documents has not been fully integrated with the computer applications. We have been developing a Web-based design automation system to manage the resultant documents as well as to speed up the repetitive design process. Manipulation of engineering drawings in the Web page is one of the critical functions needed for Web-based design automation. eXtensible Markup Language (XML) and XML-based vector graphics are expected to facilitate the representation of engineering drawings in the Web page. In this paper, we present how we used XML and Scalable Vector Graphics (SVG) to compose engineering drawings and represent them in the Web page. XML Data Island we designed to define drawing components turned out effective in manipulating the engineering drawings in the Web page.},

Organized under the umbrella of IAHR and ETNET21 this course is collaboration from several universities from all over the world. Started in 1999 the course demonstrates the potential and innovative opportunities of Web-Technology in education, research and engineering: Students from the different partner universities form small distributed teams to solve a given engineering problem in a time window of two weeks. To overcome the spatial distribution the students apply modern Web technology such as video conferencing, application sharing and document management. All results as well as the final reports are presented as Web document on a shared Web-based project platform (http://www.hydro-web.org). Besides the experiences to apply standard Web tools and working methods based on information sharing instead the conventional information exchange in the daily engineering work the students improve their soft skills operate successfully in international and interdisciplinary project environments as part of the 'Technical Culture' of nowadays.},

  abstract  = {In recent years, the survey is performed for repair, such as a bridge and a building built in past, spending great expense. And it is anxious for the survey technique that doesn't need cost and time more. Then, we made an idea of the technique of precise 3D model creation by 2D pictures. However, the technique of performing the improvement in accuracy of convergent photographing and automatic acquisition of corresponding points was not established. Therefore, in this research, we try to obtain a semi-automation of corresponding points acquisition from initial corresponding points and the improvement in accuracy of convergent photographing. Moreover, we applied the research to the used house of Japanese real estate, and the applicable field was selected as the high needs of the residence of 3D model. And we developed the system that everyone could create Web / 3D model house by VRML easily without requiring expensive apparatuses or expertise.},
