The influence of motivation factors on project performance in construction projects in Yemen

Human factors seem to be not highly respected in construction projects in Yemen. Construction project managers and contractors focus on the technical skills of project key individuals. However, less attention is paid to their capabilities of managing project people. This study is to identify motivation factors that most significantly influence construction project performance. The data were collected through a questionnaire from 91 construction project team members representing 18 project teams executed by 18 first-class construction companies in Yemen. The relative importance index (RII) was determined the most significant motivation factors. In addition, multiple regression analysis used to find the influence of motivation factors. The top motivational factors ranked by companies’ managements were; (1) relationship with colleagues, (2) advancement, (3) work itself, and (4) achievement. Among the 10 motivational factors investigated, only three motivational factors- achievement, appreciation and relationship with colleagues significantly influence the time performance of construction projects.The findings imply that the time performance of construction projects will be improved if motivation factors are properly applied in construction project environment. The study recommended proper handling of motivation factors which are a part of human factors for achieving improved project time performance.
