“…The computer modeling of the coagulation unit' spatial structure strength, with respect to the strenghening, shows that tensile stresses in concrete do not exceed 5 kgf / cm2, which is 2 times lower than the standard SNiP value (10.7 kgf / cm2) [7].…”

Over the last 10-15 years, Russia has faced a significant increase in the scope of reconstruction work (including restoration and overhaul) for buildings of various purposes aiming to extend the life cycle of existing facilities and to bring buildings in line with requirements of modern regulatory documents in terms of strength and increase in their energy efficiency. Strengthening the building structures with composite materials is by far the most ‘gentle’ method of restoring building structures and improving their operational performance. At the same time, there is only a small number of publications generalizing this type of strenghtening in the domestic scientific and technical literature. During the operation of buildings and structures (especially industrial ones) numerous factors cause accelerated degradation in building structures. This phenomenon is particulary strong in reinforced concrete structures due to their composite base. Practice shows that corrosive damage is one of the main factors of intensive constuction degradation of reinforced concrete structures. Therefore, these damages are caused by manufacturing defects (reduction of concrete protective layer), loss of concrete-against-reinforcement protective properties due to carbonization or damage. Corrosive damage greatly reduces the life capability and durability of reinforced concrete structures, which in turn leads to a decrease in the safety of construction site operations.

“…For this reason, the great importance is given to scientific, technical and economic forecasting in designing, information modeling, and construction and installation works for redevelopment of industrial areas, as well as practical use of these forecasts. Application of scientific forecasting makes it possible to carry out a preliminary assessment of the effectiveness of practical use of the proposed design, organizational and technological solutions and to improve the quality level of the project as a whole [6].…”

A large number of large industrial cities around the world are characterized by the presence of industrial sites in the Central part of the city and areas close to the center. A significant part of these zones have lost their relevance and are not used as production facilities, but function as rental businesses. The relevance of the study considered in this article is due to the need to create an organizational and technological model for the development of project documentation for the redevelopment of industrial facilities in the absence of Federal and regional programs in Russia that affect this area, as well as the lack of a regulatory framework for regulating the activities of project organizations that develop the above projects. The article deals with the General principles of developing an organizational and technological model that allows evaluating and optimizing the designer’s activity when repurposing industrial objects, as well as aimed at improving the design processes of such objects. For scientific, methodological and system-technical bases of designing organizational structures of enterprises and organization of production processes of modeling re-profiling of industrial territories, it was necessary to solve the following tasks: study and generalization of foreign and domestic experiences of redevelopment of industrial zones; identification of actual problems in the design of redevelopment of industrial territories; study of factors that affect the effectiveness of the designer; establishing the degree of influence of the identified factors on the quality of the project documentation produced. The parameters and organizational principles described in the article are taken into account when re-profiling industrial objects in the urban environment of large Russian megalopolises.

“…Based on the results of the study, the following recommendations were developed:  For the construction of housing sector and urban infrastructure should be chosen areas located away from military bases;  It is necessary to eliminate all manifestations of the military presence in the cities and beyond;  All workers should be familiar with the safety rules and behavior in case of emergencies in the workplace [12][13][14][15];  The Government needs to take active action to eliminate or reduce the number of terrorist groups;  It is necessary to provide for the conclusion of contracts for the opening of special corridors and roads for the transportation of construction materials and machinery to the place of work;  Install warning signs in designated areas and maintain constant monitoring of the construction site and the surrounding area to prevent any undesirable situations.…”

Since 2003, the territory of Iraq there were many military conflicts and conducted a large number of terrorist operations, especially in the capital Baghdad.As a result, construction work in Baghdad began to increase after 2003, which led to an increase in construction risks. The most dangerous risks were military conflicts that occurred near the construction site and affected the workforce, equipment and the construction site itself. The purpose of the study is to identify the most important factors causing risks during construction in Baghdad due to military operations and terrorist threats, to assess the degree of impact of these factors on the duration, cost and quality of construction work, as well as on the safety of workers and the economic situation of construction enterprises. The object of the study is the Al-Radwaniyah residential complex under construction in Baghdad, which is located near the US military base. In the course of the study, the most important military factors causing risks were identified, and then a questionnaire survey was conducted to determine the degree of impact of these factors among employees of enterprises involved in the construction of the specified residential complex (contractors, engineers, consultants, etc.). After processing the results of the questionnaire, the risk factors were analysed using a statistical method. This made it possible to establish the degree of impact of each factor. The study showed the degree of influence of military factors that cause risks, in particular, on the safety and life of workers, the impact on the psychological and social state of the working staff in general. It was also found that sudden military clashes and terrorist operations in the study region have a negative impact on the economic and financial situation of the construction project, lead to a delay in the project and increase its cost. Therefore, it is necessary to look for solutions to avoid or reduce these factors in areas where there is a possibility of their sudden occurrence.
