摘要：This paper describes the approaches to analysis in order to optimize the construction facilities (buildings and complexes) information models management. Two criteria have been proposed and discussed for the model quality evaluation: model informational saturation criterion and model topicality criterion. Practical application of the first criterion enables to define the optimal plan of information model filling. Herewith, the optimization is carried out through the maximum volume of useful information. The criterion is used at all stages of the model life cycle during the course of the model data updating. The second criterion allows to evaluate the need in the model data update. Being a vector (in the space of the modelling object significant values) of deviation of the model data from the model object data, the criterion represents the need to initiate the model data updating procedure using the predefined rules
