The model calculations are demonstrated on the example of a large-scale railway investment project (LSRIP) “mainland - isl. Sakhalin. Considered institutional assessments of evaluation of instrumentation and evaluation, as necessary elements of system analysis. Decades later, this project is becoming more and more real. The relevance of this study is confirmed by the words of Vladimir Vladimirovich Putin in the course of a direct translation. In which, he said about the revitalization of the construction of a bridge to Sakhalin Island and the allocation of funds in the amount of 1 billion rubles. Accordingly, it is necessary to choose a suitable project implementation model. The decision on this issue is given in this article.
