The use of normative basis for the construction cost for introduction of 5D BIM in Russia

The article considers the process of development of an information model containing both graphic and non-graphic information in a common data environment. It also gives some information concerning this process. On the basis of this information a conclusion is being drawn that the connection of additional data with the existing information models may produce a deep comprehension of a construction project, that is a design cost estimate. In its term, this property isn't expressed by a combination of others (questions of the order of erection works, various performance characteristics, a necessary project support), and it may be considered as a linear-independent vector. The authors also developed and presented an algorithm of formation of a collection of consolidated factors of the building construction cost. On the basis of the aforesaid algorithm, the conclusion is drawn that the introduction of data for the evaluation of expenditures into the information model is more efficient with the use of the existing normative basis. This fact allows the authors to show how to calculate the project cost at the stage of its development using the existing construction cost norms. The calculation of the project cost at this stage may contribute to the process of decision making, and it leads, finally, to the development of an efficient design model using an information model.
