This paper describes and analyses the impacts of the current Finnish building product modelling methodology on the building process and on construction field organizations. The objective is also to recognize and monitor changes in the design and construction environments as well as in the software platforms. In Finland building product modelling has, after 10-15 years of preliminary research, evolved into a piloting phase where the developed modelling methods are currently tested in real-life projects. One quite possible - and even more desired - future scenario is that building product modelling will become an essential collaborative working platform for building projects within the next 10 years.
