Building integrity a prototype for an it support system

Abstract: The industrialization of the building industry requires a profound understanding of the interactions between building parts, elements, spaces and systems. The industrialization also causes an increasing number of actors and suppliers to be involved in the building process. The problems concerning interactions are not limited to technical issues. The organization of the process, as well as responsibilities and liabilities of consultants, subcontractors and other actors of the process contribute to the growing implications that constitute the problem in its whole. Neglecting the interaction problems could affect what has been called the Building Integrity problem, BI. The first part of the research has been concentrated to formulate the problem and the key questions to be answered. A conceptual schema describing the BI problem tentatively has been outlined. The schema includes some interesting classifying attributes, e.g. the functions of a building, building parts, spaces, actors and the causes of building defects. A so called "defect model" has been chosen as a base for an IT Support System. The system aims at supporting certain actors to detect BI problems in the building process. A prototype system is currently developed and is described.

Building integrity: classification beyond building parts and spaces

Abstract: The effective use of information technology, IT, in the building process requires a common language of well designed classification and coding systems with clear rules for their application. To date, building elements and spaces are the principal concepts submitted to classification for the building sector. A third concept, the interactions between building parts, elements, spaces and system is less considered as an area for systemizing and classification. However, neglecting the interaction problems, which could affect what will be called the Building Intep'ty, BI, causes many negative effects during the building process and operation, eg, increased cost, low quality of the finished building and uncertain and vague distribution of responsibility between an increasing number of actors and suppliers of the building process. An analysis of the problem is presented, a few examples are given and a tentative set of principal classification concepts are established. The research is still in a preliminary stage. An indication of a possible place for an implemented IT support system, ITSS, supporting BI aspects in the building process is given.

Information transfer in the structural steel construction process

Abstract: The prerequisites for the information transfer in a fragmented building process and, in particular, the structural steel construction process is discussed. The importance of deep understanding of the real construction process prior to the development of the information transfer systems for the construction process is emphasised. Monitored seminars, utilising so called group dynamic modelling technique, have been carried out in order to increase the understanding of what information is managed and transferred in real construction processes a d why the process functions as it does, today. A tentative formal information transfer model is proposed, based on a basic information transfer model, the triple role concept, and the theory of axiomatic design.
