Against the background of growing data in everyday life, data processing tools become more powerful to deal with the increasing complexity in building design. The architectural planning process is offered a variety of new instruments to design, plan and communicate planning decisions. Ideally the access to information serves to secure and document the quality of the building and in the worst case, the increased data absorbs time by collection and processing without any benefit for the building and its user. Process models can illustrate the impact of information on the design- and planning process so that architect and planner can steer the process. This paper provides historic and contemporary models to visualize the architectural planning process and introduces means to describe today’s situation consisting of stakeholders, events and instruments. It explains conceptions during Renaissance in contrast to models used in the second half of the 20th century. Contemporary models are discussed regarding their value against the background of increasing computation in the building process.
The steel prefabricated family house ›Quelle-Fertighaus‹ designed and constructed by the German company Quelle, is an innovative modular system commercialised in 1962. All aspects of the Quelle-Fertighaus are planned on the principle of minimal effort for maximal flexibility. The clever design of the ground plan based on a 4 m × 7 m module offers the flexibility for either one to three additional modules.
The steel construction is innovative and unique, consisting of load-bearing portal frames acting as braces. The house design is furthermore characterised by a simple metrical grid layout and the practical placement of the foundation and basement, which allowed the very cost-effective production and the lowest price for a prefabricated family house in Germany during the postwar era. Nowadays its portal-frame-construction offers an interesting approach for its renovation and transformation according to present building demands.
Eine Einführung in die Anwendung der VOB in der baubetrieblichen Praxis im Rahmen der ergänzenden Schriften zu den Vorlesungen. Die Anwendung der VOB als Vertragsbedingung für einen Bauvertrag ist gängige Praxis, über die der Architekt im Baubetrieb umfassend informiert sein muß. Die Anwendung der VOB im Bauvertrag bedarf der vorherigen Vereinbarung zwischen den Vertragsparteien. Dabei muß die VOB im Ganzen vereinbart werden. Eine Veränderung dieser Bestimmungen führt zur teilweisen Unwirksamkeit der vertraglichen Vereinbarung. Der Architekt, der für seinen Bauherrn die Vergabeunterlagen zusammenstellen muß, haftet für Fehler bei der Formulierung oder der Zusammenstellung. Es ist daher für den Architekten unerläßlich, die vertraglichen Zusammenhänge zu kennen. Dieser Fachaufsatz soll zu einem sicheren Umgang mit der VOB als Vertragsgrundlage beitragen.
