This research in progress paper aims at exploring how the role of experience of practice influence users’ perceptions of an information system. The technology under study is Building Information Modelling (BIM), a technology, or methodology, which has been in focus in the building and construction industry during the last decade. The data is collected via a survey to practitioners, with and without BIM-experiences, in medium sized contractor companies, and last year’s bachelor students in civil engineering. The total number of respondents was 205. The results show that students perceived usefulness of BIM-applications is significantly higher than users’, but both groups make similar rankings of the applications. Moreover, students’ evaluation of benefits and potential obstacles shows mixed results when compared with users. Surprisingly, both groups make similar evaluations of need for structural changes if the potential of technology would be used
