Collisions in the digital information model of a construction object at the stages of design and construction and the methodology for their identification

The article presents the results of the analysis of the term "conflict" in various regulatory documents. It has been established that there is no unambiguous definition of those collisions in digital information models of capital construction facilities that have a negative impact on the construction stage when using such models as working documentation. The definition of a collision in a digital information model is proposed – a design and construction spatial intersection of elements that negatively manifests itself at the construction stage. As a result of the expert study, the criteria for the applicability of digital information models of capital construction facilities as working documentation at the construction stage related to design and construction collisions were determined. The author's model for analyzing defects that occur at the design and construction stages is proposed in the form of an Euler-Venn diagram. It is determined that the intersection matrix is an effective tool for identifying design and construction spatial intersections of elements of the digital information model of a capital construction facility. An algorithm for forming an intersection matrix is proposed to identify collisions in the form of design and construction intersections of elements of a digital information model of a capital construction facility.
