The understanding of the essence of the concept of "change", which forms a new vision of effective transformations in the public sphere, is investigated. Emphasis is placed on the need to pay more attention to finding effective ways to increase the likelihood of success of change at the level of civil society. The similarities and differences between the private and public sectors in the direction of meeting social needs are characterized. It is emphasized that ensuring successful change and sustainable efficiency in the public sphere is a work with unique obstacles. It is noted that usually in solving problems in management resort to traditional methods of responding to change, but this approach is no longer relevant in the public sphere. Change management is recognized as a critical technology used in the management process to increase the likelihood of success. It is emphasized that change management aims to provide the benefits and desired outcomes of change. The generalized scheme of change management process and classical models of change management are presented. It is stated that in Ukraine the society strives to move to project thinking with setting clear goals and developing an action plan. The relationship between the concepts of "change", "change management", "project management" and the mandatory components of the change management mechanism are presented. Methods for assessing the probability of success of change are presented and a generalized scheme of the process of change management in the public sphere is developed. The need to use change management technology in practical focus is emphasized. Positive developments in this direction have been identified: approval by the National Agency of Ukraine for Civil Service Affairs of the general short-term training program "Change Management", which, of course, can be considered a positive aspect; availability of methodological support for change management.

The article analyzes innovative ways of using crushed solid plastic in a mixture with soil for arrangement of soil embankments for various purposes. Using a mixture of loam loess and crushed plastic, on the one hand, solves the environmental problem of plastic recycling, and on the other hand, creates technological material for the erection of the embankment. In order to determine the suitability of the material, laboratory studies of the characteristics of the mixture were carried out. For each sample of the mixture, the optimal humidity and density of the skeleton were determined by dynamic compaction in the MDU-1. The modulus of deformation of the compacted specimens is determined. The article investigates the characteristics for the composition of the loam loess and crushed plastic containers in the ratio of 80:20 %.

The monograph presents a comparison of mathematical and numerical calculation methods as the most promising in this field. Calculations by the above methods are proposed to be carried out according to the second limit state, that is, according to deformations, to determine the amplitudes of oscillations and settlements of the soil and structures. The mathematical method of dynamic phenomena was investigated using an idealized mathematical apparatus. The case of foundation oscillations is described if the soil exerts elastic resistance to compression and displacement. Calculations to determine the dynamic characteristics of foundations are recommended to be carried out in two directions: using mathematical equations and using software complexes. The use of a mathematical method in dynamic calculations allows to describe mathematically with the use of certain assumptions and to determine the dynamic characteristics of object oscillations, foundation settlement, which can be described using formulas. And the software complex using the numerical method of finite elements makes it possible to obtain a complete description of the field of vibration displacements, vibration accelerations, and vibration velocities. At the same time, graphs of the dependence of dynamic characteristics at any point of the calculation scheme on time and a graphic description of the deformed grid were obtained.
