This category poses the largest latent barriers to the
application of BIM. According to the results of questionnaire,
about 40% of respondents from USA and
about 20% respondents from UK believe that their

evidence. [10] Moreover, social and habitual resistance
to change, as lots of architects are satisfied with traditional
methods to design their projects and are incredulous
of the new functions and advantages of BIM.
