The article presents a mathematical model of the multi-pass surface treatment route. The method reduces the amount of calculations compared to the directed search method and guarantees a global extremum of the target function. According to the proposed method, an algorithm and a program in Visual Basic have been developed.

Sustainable development means the ability of an object to maintain the required level of environmental, social and economic indicators while meeting the needs of not only the living, but also future generations. These standards suggest using a uniform estimated figure that considers economic, environmental and social indicators. Design with resource-saving technologies has become an important part of the developed Terms of Reference for the project, and environmental friendliness has become a key element of the business center marketing strategy. The research is aimed at developing a business center construction project as a sustainable development model. The research results are the following tasks: to perform calculations on the total cost of the building’s life cycle; perform the project economic efficiency assessment; consider technical solutions for power consumption systems, building heat supply and water consumption systems; analyze the sustainability of the project environment; identify the risk levels for the business center construction project development. The research itself develops a concept for the project implementation, project risk analysis was carried out, the categories for assessing the environmental sustainability were compared with possible technical solutions of the project construction. There were also considered technical characteristics on internal and external lighting, heat supply of the building, water treatment and re-use, and energy-efficient elevators. The conducted risk assessment revealed a low cumulative risk of this construction project development. With the factored level of incomes and expenses, the project can be recognized as efficient. Further research matters can be issues of a detailed study at the level of a comprehensive ESG risk assessment of contemporary construction companies.
