LE IM: Living Environment Information Modelling

Abstract

The article deals with the information models in construction. The models of different levels are reviewed: flat 2D drawings, 3D volume models, models including time indicators - 4D, models supplemented by financial indicators - 5D, models containing information on a wide range of resource and other indicators - N-D. The importance of an integrated approach to the formation of the information model of the building - BIM was noted. To date, BIM-technologies are used only at the design stage and partially at the construction stage. However, the greatest return can be obtained from the operational phase. The author proposes the introduction of the concept of an information model of the building life cycle - BLC IM. The analysis of the reasons predetermining the problems of mass introduction of BLC IM into construction practice is carried out. The contradictory nature of the interests of the participants in the construction process, the lack of common goals does not allow them to form and use a unified information model. The mathematical description of the information model of the building object is presented.
