Nowadays, we encounter risk in every project. Contrary to the impression of associating risk exclusively with big projects, risk has an even more critical role in small projects. This importance stems from limited available human and capital resources. As a result, a coherent management and orderly planning are essential to complete a small project. In this regards, identifying risk and proper response to it are very important tasks to accomplish. This paper is dedicated to studying the impacts of risk management on the performance of small construction projects in Iran. Two questionnaires were designed in the process; the first one aimed at identifying small construction projects and the second was distributed among the elite of the construction companies which were involved in those projects according to the first poll results. This second survey identifies the barriers to implement risk management in projects and also evaluates the impact of risk management on the organizational performance. Upon collection, the data was analyzed by parametric and nonparametric tests which determined the elements affecting small construction projects and their challenges. It is good to write findings and implications here.
