Risk management is pivotal to the success of many projects of nowadays. However, the risk management process becomes quite challenging when accounting for the complex dependencies amongst risks. One risk can contribute to the development of another and vice versa. The paper employs the N-squared Diagramming Method for the modelling of such relationships. The n-squared diagramming method was originally developed in the systems engineering (SE) domain to relate system functions. Strength of these diagrams is in their use to visualize and specify the interfaces between the elements of a system. While for years the n-squared diagrams were used for a better understanding of physical systems, only recently scholars started to recognize their potential in project planning and management as well. Paper primarily establishes a basis for using n-squared diagrams in risk dependency modelling. With complex project environments that combine multiple risk events, the arrows of an n-squared diagram can be used to depict the dependencies whether one or two directional. In the paper, this approach is further exemplified in pipeline construction projects. Knowledge was acquired via expert feedback and used to construct the diagrams in reference.
