The experience of the design of berthing facilities in Russia and other countries is considered. A typology of mooring structures (piers, marinas, river stations) is given and their characteristics are disclosed. Specific examples show solutions to functional issues of operation and design of berthing facilities. It was established that most of the existing river stations in large cities of Russia were built in Soviet times according to standard projects, without taking into account local specifics, which does not meet modern requirements. An analysis of world experience showed that such structures can be organically integrated into the existing landscape, giving them the status of an object of multifunctional public purpose.

The fundamental Boussinesq solution for a two-phase half-space obtained based on a kinematic model is used to calculate the stress-strain state of the base after the consolidation process. The results are presented for two uniform loads distributed over a circular or rectangular platform, the distance between which can vary. The solution is illustrated by graphs showing the effect of the liquid phase on the stress field and the displacement of the solid phase.

In the theory of optimal design, problems are considered in which it is necessary to determine the working conditions of structures, the internal properties of the material of structures, shapes and sizes that take the maximum or minimum values of the selected design characteristic.

This paper deals with structures formed from spatial fiber composites. Three stages of optimization are given. The target function, control function, and limitations are selected. Several options for boundary conditions are considered. The differential equation of vibrations of an orthotropic plate in displacements is obtained.

This article presents the features of modern concrete, shows the development prospects. Experimental data of concrete production with a strength of up to 70 MPa are presented, characterized in that along with chemical additives local aleuropelite rocks of the Ishim suite in the south of the Tyumen region are used. The physical and mechanical properties of cement and concrete are analyzed in the article and conclude that the complex of modifying components allows without increasing the cement consumption to increase the mechanical characteristics of concrete by 30-40 %.

In recent years, the world has seen a decline in the consumption of water by its population. This is due to the increase in the cost of water and the installation of water meters in apartments. Currently, in Russia, the actual water consumption per inhabitant is lower than the established standards. Factors affecting water consumption are up to 15 items, such as the density of residents in the apartment and their position in society.

The paper presents the measurement of water consumption in apartments with a different number of inhabitants, looking at the inhabitants of different ages. Deviations from the recommended values for the calculation of internal water supply networks are noted. Based on actual water consumption measurements for various inhabitants, daily water consumption values for various observation periods (day, week, month, year) are given. The average daily rate of water consumption per 1 resident in the apartments under consideration was 74 liters/ per inhabitant/day.

Competent management of executive documentation ensures the successful implementation of construction projects. The need to translate executive documentation into electronic format and the degree of implementation of this process at the moment are shown. The article provides an analysis of some software products, based on which it is planned to create the universal system in the future, that has the best functionality of the existing programs and includes new tools.

In this article, methods were selected for the improvement of the coastline of water bodies. The main problems associated with water bodies degradation are considered today. The analysis of the existing methods of their cleaning is carried out, proposals for the creation of a complex of machines and equipment for their cleaning from pollution and associated processing of sediments that are extracted directly from the bottom are developed.

The paper describes the main advantages and disadvantages of mobile service stations and identifies ways of solving them. As one of such solutions, the slide out system was modeled, the loads on its sliding parts were calculated, and the overall internal dimensions of the areas were determined before and after the system was used.

The starting mode for a composite transport and technological vehicle is the most difficult. The aim of the work is to build a mathematical model of "easy" starting of a composite transport and technological vehicle with elastic couplings. The softening of the starting mode is essentially due to the replacement of the simultaneous starting of the sections with alternate ones. To exclude longitudinal vibrations of the composite transport and technological means, after reaching the maximum tension of the coupling, the possibility of its harmonic compression should be mechanically blocked.
