Existence of delays is an inseparable part of projects and subject of disagreements among stakeholders in all countries. There are four valid techniques in the Society of Construction Law global protocol about project delays calculation that without having the ability to control the risk of delays incidence only calculate the prolongation of contract prolongation and consider it as project delays. Researcher believes: first, risk of delays should be managed, minimized, shared, transferred, or accepted, but it cannot be ignored; therefore, it must be predicted, covered, managed, and optimized; and second, prolongation time of project is not necessarily equal to increased delay amount, and many other factors that themselves are the basis of emergence of project risks are effective in calculation of delays. Therefore, it is necessary to identify these factors and develop the strategy for their control and management before starting the project. So, in this article, two researcher-made combinative techniques are presented in order to resolve this deficiency: first, introduction of importance degree factor model instead of weight factor; and second, introduction of a model in the field of claim management in order to controlling risk of delays, analyzing result-oriented delays, and determining the share of stakeholders’ failures, based on variance and importance degree.
