This study evaluated the effect of three factors of project, construction, and risk management on the time, cost, and execution process of the projects based on a case study regarding building mass construction projects. This survey study was conducted on ۱۵۰ professors, experts, and contractors in the field of housing mass construction in Tehran province. A total of ۱۰۸ people were selected as a statistical sample by determining the sample size of Morgan's table by simple random method. The data collection tool is through a questionnaire, the validity of which has been evaluated based on the opinion of professors' experts and its reliability based on Cronbach's alpha coefficient. Cronbach's alpha was ۰.۸۲, indicating the research tool's appropriate reliability. In this research, different descriptive and inferential statistical methods were used to analyze the data using SPSS software to classify the characteristics of the respondents and the statistical population. Cronbach's alpha test was used to check the reliability of the questionnaire, and tests, including the Kolmogorov-Smirnov test were utilized to check the normality of the data distribution and the sample t-test. The results showed that mass housing projects have more risks than normal constructions. Contrary to the fact that mass construction projects with high importance are in the first rank, mass construction projects with low importance were in the first rank, and after that, high and medium projects were in the second and third ranks, respectively.
