The purpose of this paper is to elicit how much time general superintendents and superintendents spend on different functions and, in specific, how much time is spent on work planning and preparation and supervising the work. A survey, in which 14 general superintendents and 10 superintendents filled in their time usage into a web database for one month (22 days on average) each, was carried out. The respondents could allocate their working hours in 16 different functions with the accuracy of a half an hour daily. In addition, one question was asked concerning the laboriousness of office work and IT systems, for which 14 answers were obtained. All answers were categorised based on the occupation of the respondent in general superintendents and superintendents. The supervision of work is still the most time consuming function for the general superintendent and the other superintendents; whereas work planning takes up only 15% of the site management’s time. This finding shows that at the moment the site management rather supervises than plans and makes pre-requisites ready. Much of the non-value adding time could be eliminated by improving project management and designer cooperation and putting more emphasis on work planning and preparation.
