This study was conducted with an objective of identifying quantifying, and ranking of construction projects management success determinants. The focus of the study was on the medium level contractors i.e. grade-6, 7 and 8, including both general and building contractor categories. There are 4330 medium level contractors in the study area that provided total population. Therefore taking this population the calculated sample size was 366. The study selected four success criteria that are time, cost, quality, and stakeholder satisfaction. And a total of 66 success factors compiled in six groups (Management, Procurement, Client, Contractor, Project Manager, and Environment Related Success Factors) from literatures. The data collection was conducted using questionnaire having 5 level Likert scale and distributed to 370 respondents (including contractors, consultants & owners) out of which 275 responses were received. The data were analyzed using computer software. The analysis was divided into general characteristics (grade and experience of contractors) and relative importance index analysis. Relative index analysis was selected to rank the factors according to their relative importance. For each success factors group a cumulative mean was calculated to identify the significance level of the success factor group according to the Likert scale. Then by computing the relative importance on the elements of the success factors the ranking of each element was done to identify which of the factors are ranked the highest three in their respective group. Finally the ranking of all the 66 success factors in the six groups was computed together to identify the major 10 significant success factors. The results showed that 50% of the ranked ten major success factors come from the Project Management Related group, 30% are from the Contractor Related group, Environmental and Management Related factors provide 10% each.
