Construction projects have distinctive characteristics and are very complex, so that risk events can have a serious impact on the viability of the project. A lack of attention to the risks faced will affect project implementation by creating delays, resulting in losses. The purpose of this study was to (1) identify the risk factors that cause delays in construction projects and (2) determine those particular risk factors that have a greater influence on construction projects. The location of this research was Central Aceh District, Indonesia. Methods: The data in this study were primary data in the form of a questionnaire and secondary data obtained from the literature related to this particular type of research. Questionnaires were distributed to respondents, namely contractor companies located in the Central Aceh District. The questionnaires were distributed to determine respondents' opinions about the level of influence of risk factors causing project delays. We used a validity test, reliability test, and descriptive analysis for data processing. Results: Based on the results of the study from 47 respondents, the “very high influence” category (Mode=5) for the tool malfunction factor was chosen by 21 respondents (44.68%), cost estimation inaccuracy by 20 respondents (42.55%), increased work costs by 22 respondents (46.81%), implementation of new technologies by 25 respondents (53.19%), details, accuracy and conformity to specifications that are not appropriate by 20 respondents (42.55%), worker quarrels by 20 respondents (42.55%), poor project planning and management by 22 respondents (46.81%), poor condition at locations and accessibility difficulty by 20 respondents (42.55%). Conclusions: Of the 80 risk factors that caused project delays, eight risk factors were found to have a very high influence on the implementation of construction projects in Central Aceh District.
