Identification and analysis of design risks of fast cable construction structures by sorting and scoring method

Risk management is one of the most important aspects of the project. Risk management includes various areas such as planning, identifying, evaluating and controlling risk. In construction projects, due to the fact that the process of project implementation is known before the start, first the project risks are identified so that in case of encountering them during implementation, principled and efficient measures are taken. In research and development projects; Risk management is used to improve project implementation process, cost management, increase project profitability and is effective as a scientific and effective tool to reduce risk and loss. One of the most common methods of risk identification is to use the Delphi method and consult experts and the project team. This study identifies the risks of the design phase of the research and development project of rapid cable structure design, for this purpose 313 risks identified in eight groups of general executive risks: structural, mechanical, geotechnical and foundation, then three proposed designs were developed according to the evaluation of the severity of the effect and the probability of risks, and eight designs were obtained. According to the results obtained from the risks, these eight designs with eight criteria of fast construction, portability, These two methods are among the oldest methods of multi-criteria selection. In the scoring method, the score is at the disposal of experts, but in the method of sorting designs, they are placed in order. Finally, the selected designs were determined according to the effective parameter of span length.
