The features of classification of construction products and construction materials are considered, and optimization of their existing classification structure is proposed. The analysis of existing domestic and international systems of classification of construction information, domestic normative and technical literature is carried out and classification features for construction material and construction product are determined. The optimization of the classification tables (CTs) based on the application of the principles of the ISO 81346 standard series and the refusal to duplicate the structure of the construction resources classifier, on reducing the number of classes and subclasses taking into account the ISO 81346 criteria and moving classes and subclasses within CTs with the corresponding changes in the code designations is suggested.

The experience of standardization of modular construction and factory-ready buildings of China, the USA, Canada, Great Britain, France, the Netherlands, Germany and others is considered. The analysis of the existing profile regulatory and technical documentation (RTD) in the Russian Federation. The analysis of domestic and foreign RTD showed that there is no unified approach to rationing of the considered subject area. At the present time it is necessary to update the Russian RTD in the field of modular construction. Based on the results of the analysis and synthesis of the world practice in the field of modular construction, recommendations and suggestions for working with terms and definitions, the variants of development of normative and technical documentation of the Russian Federation in the field of modular construction and themes of work for the development of modular construction regulation were developed.
