The foam plastic capable to work in frame panels as a thermal - insulation and facing and decorative material can be only of composite type. We have developed a new type of composite foam plastic, its density increases from center to surfaces. The article presents the composition of new material, the technology of its production, as well as the mathematical model of the mechanism of formation of strong crusts at its surfaces. Microscopic analysis of the composite showed that the density of crust is more than 200 kg / m3, the density of the foam plastic in its middle part is 80 kg / m3. The limit of strength at punching it by the rod diameter 0.01 m reaches 3.5 MPa. The material is used for the manufacture of roofing panels, frame panels with an internal non-metallic layer.

“…All waste producers, regardless of the form of ownership and departmental affiliation, are required to have technical and technological documentation regulating the process of handling the construction and demolition waste generated by them in the form of technological regulations. It should reflect complete and accurate information on the whole process of waste management and demolition from the moment of their formation to the moment of their use or disposal ( [16][17][18][19][20][21]).…”

Throughout the world, the intensive development of production is accompanied by a steady increase in waste generation. Ecological problems, problems of utilization and recycling of waste come to the fore. The effective functioning of the construction complex is largely determined by the effective organization of the construction and demolition waste (CDW) circulation. Considering the scale of construction, forecasting the volume of waste formation in order to effectively organize the system of economic turnover of CDW is a very relevant scientific and practical problem. Management of CDW flows in Smart cities should be based on information models containing the necessary data on the types, forms and volumes of waste. The paper presents such an information model and a mathematical method of predicting the formation of the CDW. Information modeling of the composition and volume of CDW formation allows on the basis of the developed mathematical apparatus to provide an analysis of construction development trends. It allows to carry out construction production operational and strategic planning and management in terms of the CDW formation, processing and disposal. Analysis of the construction, reconstruction and demolition CDW volume dynamics information model is the basis for further design of treatment plants future scheme.

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.
