“…For the successful implementation and execution of construction and installation work and to avoid cases of suspension or inability to complete the construction of a facility, it is important for participants in investment and construction activities to calculate the risks that arise at all stages of the implementation of investment and construction projects [1,2,3,4]. Traditionally, the risks of project implementation are usually calculated for customers who organize the construction process on behalf of the investor or developer [5,6,7,8]. At the same time, contractors, as the main participants in the construction process, are also interested in its effective implementation and completion [9,10,11]; they bear the risks of working with an unscrupulous customer, using low-quality technical documentation, undervalued work prices, etc., which ultimately can lead to failure to fulfill contractual obligations and bankruptcy.…”
