The concept of digitalization of the construction organization project (POS) is presented, which is based on its close connection with the construction schedule. The place of the POS in the digital model of the building at the project stage (PIM) is considered. based on its digitalization, taking into account the relationship between information modeling at the project stage (PIM). The main problems that may arise when implementing the digital version of the POS in the general information model at the project stage are identified.

The model of mobile system of diagnostics and automatic regulation of multiphase environments flow regimes is considered. The analysis of existing methods for determining the thermal parameters of a mixture of several gases and liquids in the presence of particulate matter in the stream showed the relevance of the small size mobile systems, in which the measurement is made with modern sensors for pressure, temperature, gas content. Control signals state multiphase flow formed in the controller based on the values of the complexes Kutateladze - Sorokin, Baker. Specific designer elements of diagnostics and regulation system development of multiphase environments flow regimes is offered. The directions for further research in relation to specific multiphase systems are planned.
