| dc.description.abstract | Construction sector plays key role in national development as one of the principal drivers of economic growth. The sector involves multiple stakeholders such as clients, contractors, consultants and others which complicate its performance. It encounters numerous problems and difficulties related to cost, time, scope and quality. This paper aims at identifying and examining the key factors that influence the construction projects performance within the study area. The study employed stratified sampling technique, categorizing participants into three key stakeholder groups: clients, contractors, and consultants. Primary data was collected from the three stakeholders (owner, contractors and consultant). Questionnaire survey was administered using 24 factors identified from previous literatures and grouped into 5 groups. A total of 153 questionnaires were distributed, with 129 collected and returned: 18 (100%) from owners, 101 (82.8%) from contractors and 10 (77%) from consultants. A quantitative research approach was employed in order to investigate the key factors influencing project outcomes. The study employed a mixed-methods design, combining descriptive and explanatory research designs. The data received were analyzed using SPSS version20 and Microsoft excel, and its outputs were ranked using relative importance index (RII) to determine owners, contractors’ and consultant perceptions of the factors influencing performance in construction projects. The most important factors of RII that were agreed upon by all project parties were that poor project team leadership, unclear and inadequate details in drawing designs, poor planning in acquiring and using project equipment, lack of consultant monitoring during execution phase, unclear project scope definition etc. The study also employed correlation analysis to examine the associations between independent and dependent variables, and it is found statistically significant and acceptable correlations. Multiple linear regression analysis was also conducted and it is found that all the results of the regression analysis of all factors influence the construction performance positively. In the study, the model explains 80.8% of the construction project performance based on the studied variables, leaving 19.2% influenced by unexplored factors. So, the researcher recommend that future research should identify these missing variables to better control performance determinants and further examine their positive impacts on construction project projects. This will enhance predictive accuracy and project outcomes. | |
