The relevance of experimental and theoretical studies of improving the operational efficiency of construction arbitrariness is justified. It is established that the operational efficiency of a construction site depends on many factors. In order to identify the main features of improving the operational efficiency of construction production in this study, we used a computer method of relative distribution of premises and computerized planning of relationships and layout. Some features of the system operation at increasing the operational efficiency of construction production are determined. Based on the conducted experiments, the need for further study of improving the operational efficiency of construction production is justified. Also, on the basis of a number of experiments, the influence of the operational efficiency of construction production on the economic aspect of construction was proved.

Modern design cannot be imagined without the application of BIM technologies. Modeling is increasingly used in the design of new construction of buildings and construction, renovations and major repairs, which makes up the majority of projects underway. 2D programs are still used for the inspection of buildings and construction. Visual and instrumental examination is not a difficult task requiring complex programs. But the introduction of BIM technologies ensures the acceleration of work on the inspection of buildings and structures, significantly improves the quality of the result, and also maximizes the actual condition of building structures.

Recently, the issues of improving the environmental situation in the urban environment have become more relevant than ever. "Green architecture" gets popularity not only in Russia but over the world as well. The necessity of this type of architecture causes the need to improve air quality and environmental factors of urban conditions. Most often, greening the roof of a building or greening the facades is used for ecologization, so-called the element of wall greening and also greening of vertical surfaces of buildings (phyto facade).

With information modeling of buildings, the time and money spent on creating a building project is significantly minimized, and it also becomes possible to make changes to the project, reducing the likelihood of a designer making a mistake. However, building information models have a number of disadvantages expressed at each stage of the object's life cycle. In this article, the main stages of the life cycle of a building were highlighted, according to regulatory documents. The drawbacks of using information models at each stage are highlighted and their influence on the work in the information modeling environment is considered. Ways to minimize these shortcomings, taking into account the prevalence of BIM-models of the building at the present time, are proposed. The general problems of transition from the classical design method to information models are highlighted.

Rostov-on-Don is one of the largest cities in Russia, it is planned to renovate the territory of the old airport, which in turn can stimulate an increase in the load on the city's transport system. In this regard, the issue of proportional development of the city's transport infrastructure is becoming especially relevant. The solution to the problem can be the modernization of the current and the creation of a conceptually new transport and logistics structure aimed at using passenger transport. This issue is considered within the framework of the concept of sustainable development of the city.

The use of renewable energy sources is an integral part of ensuring the engineering safety of buildings and structures. The article provides a brief study of the sources of electrical energy generated by the energy of rivers, dams and thermal energy of the Earth in Iraq, examines the most important rivers in Iraq and their storage in order to maintain a clean environment and simultaneously generate electricity. The results of Iraq's hydropower analysis revealed the need to build dams on the Tigris and Euphrates rivers for water storage and energy production to maintain environmental cleanliness. The study details the benefits of building dams for many purposes, including irrigation of agricultural land, prevention of natural disasters and conservation of the environment.
