TY - CHAP A1 - Garrett, James H. A1 - Sunkpho, J. T1 - Issues in delivering it systems to field users N2 - IT support for field personnel is starting to appear on bridge inspection sites, construction sites, and on the manufacturing floor. ENR magazine now regularly advertises palm computing-based systems for recording data on a construction site. This support can, and should, take on many forms and functions and needs to be carefully designed and evaluated like any other important tool used in the field. With careful design and implementation, IT devices for the field should have tremendous impact on the productivity of field personnel. If the devices are not carefully designed to take account of the field context and the abilities and preferences of the field personnel, field workers will not use these tools.

First, the images of the building are registered as database by the questionnaire. Next, the images of the objective building are compared with the degree of matching in image databases, and the building with high synthetic matching degree is retrieved. This system could get a good retrieval result. Moreover, image processing was done, and image databases are trained by neural network from the amount of characteristics of the image, and the retrieval system by image processing was examined.

The system uses a generalised object-oriented approach for information modelling of physical state variables from measurements and simulations by sets of tensor objects and is implemented platform-independently as a Web application. 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.

Hierzu erfolgen Untersuchungen von Methoden, Verfahren, Strukturen und Abläufen sowie der in Bauunternehmen angewendeten Informationssysteme. Grundlage einer Modellierungsmethode sind Abstraktionen von Prozeßschritten und Ereignissen in einer Ereignisgesteuerten Prozeßkette, Entitytypen in einem Entity Relationship Model, Funktionsbäume und Organisationseinheiten sowie deren mögliche Relationen. Mit dieser Methodik werden die Prozesse, Informationsdefinitionen, Funktionen und die Organisationsstruktur einzeln modelliert und Relationen zwischen den Modellelementen gebildet. Aus der fachlichen Auswertung der Modelle und Relationen folgen fachgebietsspezifische Prozeßabläufe und Arbeitsumgebungen. Deren Anwendung wird für ein Customizing vorhandener Informationsysteme und bei einer Neuimplementierung betrachtet. Neben einer umfangreichen fachlichen Problemanalyse leistet die Arbeit einen Beitrag zum methodischen Vorgehen bei Neukonzeption baubetrieblicher Informationssysteme. N2 - The specialized and organizational tasks in the information processing of tendering and contract execution in the construction industry are formaly described as theoretical basis for customizing and redevelopment of a information system was distributed in a network. For this purpose it is essential to examine methodes, procedures, structures and the course of events as well as information systems in a building enterprise. Basis for a methode of modeling are selected abstractions for steps of processes and events in a Event-driven Process Chain, entitytyps in a Entity Relationship Model, trees of functions, units for organisation and there usually relationships. With the help of this methodes the processes, the definitions of informations, the functions and the structures of organisation are separated designed and form relationships between the elements of modeling. The results of the specialized evaluation of the models and relationships are course of events and enviroments for special fields. The application of this results is investigated for a customizing of existing systems and development of a new information system. In addition to a surround specialized analyse of problems the work gives a contribution for methodical procedure and reengineering of information systems in the construction industry.
