Abstract
An improved information exchange is frequently proposed as one solution to the inefficiency problems which the construction industry is suffering from to- day. Such an improvement is very dependent of the use of information technology, IT. To enable an advanced use of IT, there is a need for integrated project communications frameworks and integrated industry wide information. This thesis discusses how product models can be used to improve the information exchange from design to construction. Today there are several approaches to product modelling. Some researchers propose very detailed models whereas others propose generic models with fewer concepts. In this area there is a close connection between research and standardisation, which is carried out by organisations such as the ISO STEP committee and the International Alliance for Interoperability. To get acceptance for a standard proposal, it has to be accepted by both users and standardisation bodies. Thus, this research, in addition to the technical requirements on information content and structure, also discusses success factors for standardisation, implementation and usage. In order to define important requirements on a product model for information exchange between design and construction, current research, development and standardisation in the field of product modelling was studied. This thesis advocates a minimal approach in the number of concepts used in a product model, in combination with an external building element classification, following national industry practice. The minimal NICC schema, developed during this research, was tested in a prototype and test study. Three applications were tested: PreFacto (planning tool), Microsoft Project (time scheduling tool) and Calc3(cost estimation tool). From the CAD-system MCAD, NICC files with the building objects were created and transferred into a relational database from which the three applications received their specific input files. The results of the evaluation of the NICC schema and the test study demonstrated that a product model based on few concepts can manage the required in- formation exchange.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
