The construction of facilities in cluttered urban conditions requires a special approach related to the need to develop and implement measures to ensure accident-free operation of buildings of the surrounding development within the geotechnical influence limits. Often, builders neglect the influence of the technology of construction of a new object on possible negative defects (cracks appeared on the facades due to uneven settlements, tilts, etc.) of the buildings being operated. Until now, the concept of «minimum price» is exaggerated when building the part of the building below the zero mark, ignoring the technical feasibility. At the same time, builders go to any tricks to reduce the cost. Such «irrational» method of construction ultimately could lead to a significant cost increase in construction of the zero part of the building and, as a rule, to an increase in the period of construction (approval of the new project as a result of replacement with another geotechnical technology, passing the new construction expertise). A negative case from the geotechnical practice of construction of a 16-storey residential building next to the existing five-storey residential building is considered.

The relevance of the study is related to the need to take into account climate changes in order to predict the structure of the building’s energy balance. The subject of the study is the dependence of energy consumption by building microclimate systems on the increase in the average annual temperature in the construction area. The purpose of the study is to estimate the total energy consumption for building climate control under conditions of a set degree of climate warming. The task of the study is to obtain a mathematical description of the annual change in outdoor temperature and analytical expressions for the duration of the heating and cooling periods and the degree-days for these periods. The representation of the annual course of the ambient air temperature in the form of harmonic oscillations with a certain average value and amplitude is used. By integrating this expression within the necessary limits, the dependencies for the degree-days of heating and cooling periods are obtained. Calculations based on these dependencies were made for the climatic conditions of Moscow within the limits of an increase in the average annual temperature by two degrees, and the results were analyzed. It is shown that under the conditions of the studied variant of climate parameters change, the decrease in energy consumption for building heating and heating of the inflow during the cold period is more significant than the increase in the consumption of cold for cooling in the summer. Therefore, under the conditions of Moscow, climate warming can lead to a decrease in the total annual energy consumption for providing the building’s microclimate.

It is difficult to imagine the development and effective functioning of the construction industry without the introduction of innovative management, technical and technological solutions. The use of new materials and technologies contributes to the creation of popular construction products in the form of buildings and structures for various purposes, which in turn increases the competitiveness of enterprises. It is known that the innovations introduced into the construction industry are complex organizational and technological decisions made in the dynamics of the functioning of the enterprise and its construction activities. However, the application of innovations in the construction industry is often associated with certain risks. It is not always the funds spent on innovations pay off. Meanwhile, it is worth noting that it is impossible to achieve a stable state of an enterprise without introducing innovations. The article describes the relationship between innovations and sustainability of a construction enterprise, considers the types of innovative materials and technologies used in construction, analyzes the impact of innovations on labor productivity. The concept of sustainability is given from the point of view of the achievement of the set goals by the construction enterprise, which are determined by the chosen management strategy. Measurements of the progressiveness of the applied machinery, equipment, materials, and technologies that affect the innovative potential of the construction enterprise are described.

Construction technologies have features that, depending on the location and tasks of construction, act as advantages or disadvantages of the architectural and construction system. The economic struggle of construction companies at the housing construction market can lead to irrational use of house-building technologies when solving urban architectural and construction problems. This was the reason for a comprehensive assessment of the rationality of the use of house-building technologies in various conditions of urban construction. The authors consider the problem is not so much from the interests of the developer and the contractor, but the city’s architectural-construction tasks and interests of consumers of construction products. When conducting the study, the task of selecting criteria for comparing house-building technologies was first solved, then the technologies of modern architectural and construction systems were evaluated according to the selected criteria. The method of expert evaluation is used for quantitative evaluation of the compared house-building technologies. According to the results of the study, a conclusion is made about the rational application field of the main house-building technologies. Monolithic house-building technology has more versatility, because it is applicable in the conditions of the historical center, especially in combination with monolithic technologies for the development of underground space, such as a wall in the ground, bored piles, and the «top-down» method. At the same time, for social housing in new territories, it is rational to use, especially in conditions of mass construction, the technology of prefabricated large-panel housing construction. In addition, the article considers the conditions for the rational use of traditional masonry and prefabricated monolithic house-building technology.

The analysis of existing methods of calendar planning of construction production is carried out. It is determined that in practice, the optimal implementation of the project is complicated by external stochastic influences, which necessitates dynamic adjustment of the project implementation process. It is shown that only when the discrete nature of resources consumed has a weak influence on the pace of work on the project, the parameters of the catch-up schedule are determined by the dynamics of the time-averaged volumes, rates, and accelerations of work. In the opposite limit, speeds and accelerations of work experience a jump at the moment of changing the number of used resources. In this case, the speed of work is determined by the usage profile of the dominant discrete non-stackable resources. The dynamics of work volumes, in contrast to their speeds, demonstrates a weak sensitivity, both to the discrete nature of resources and to external stochastic influences, and can not serve as a basis for dynamic adjustment of the schedule. It is shown that time averaging leads to loss of information about these features of construction dynamics. An algorithm for forming a catch-up work schedule is obtained based on the results of monitoring the work rate and averaging only the number of discrete resources over periods of constant composition. Both an empirical method for separating stochastic and deterministic effects on the course of project implementation, and a method based on the qualitative difference between the Fourier spectra of stochastic and deterministic functions have been developed. The limits of applicability of empirical and exact methods are analyzed. It is shown that the Fourier analysis of the monitoring results makes it possible to completely restore the deterministic information even against the background of a stochastic signal that coincides with it in intensity. It is shown that the proposed algorithm makes it possible to formulate the parameters of the catch-up work schedule, which allows avoiding financial and image losses associated with the untimely completion of the project or its main parts.
