The use of information and communication technologies (ICT) in building and construction companies has steadily been growing during the last decade. However, just a few studies inquire perceptions of the ICT actually being used and perceptions among different professional groups in companies. The objective of this paper is to contribute to an enhanced understanding of general perceptions of ICT in building and construction companies and among professional groups by taking the point of departure in the concept of perceived usefulness. Data was collected by a web-based survey in two regional units of a major Swedish building and construction company. 257 completed questionnaires were returned which corresponds to a response rate of 49 %. The data was analysed with T-tests and multiple regression analysis. It can be concluded that respondents are generally fairly satisfied with their ICT and that the ICT is perceived as necessity for the fulfilment of work tasks as well as a valuable support in various areas of decision making. Moreover, a further developed use of ICT is perceived as an opportunity to increase the company’s competitiveness, but this opinion is negatively correlated with the opinion that the ICT is well adapted to the industry’s conditions. Finally are there some significant differences in perceptions of the outcomes of ICT-usage among professional groups. These differences can be explained by distance to operations and nature of work tasks.
