This report starts with the analysis of theoretical aspects of BIM as a new trend to manage building projects: general advantages, the conoept of interoperability, the automatic process of quantity takeoff and finally the use of BIM for planning and estimating construction activities. Then, based on this theoretical part both quantitative and qualitative researches are developed in order to show: the real influence that the method of designing has on the accuracy of quantities whereas, the qualitative research is focused on explaining that BIM is not equal adoptad by all companies that work around the same project. Architectural firms represent the institutions that more use BIM for designing followed by engineering consultancies and construction companies.
