The construction industry has placed itself as one of the most important sectors of any economy as other sectors depend on its products for survival. Emotional Intelligence is one of emerging research areas in checking the behavioural disposition of the people involved in the construction process to achieving a better performance rating. Emotional Intelligence is a tool for promoting personal growth by the ability to perceive emotion, facilitate thoughts by integrating, understanding and regulating emotions in achieving a set goal. This paper looks into the factors that affect the emotional intelligence of four construction professionals in the industry. Through extensive literature review, twenty-two factors were found to affect EI. A total of 243 questionnaires were analyzed. The survey findings indicate that Experience, family background, personality, skills and competencies are the most important factors that affect EI of construction professionals. It was also gathered that gender and age are some of the trivial factors that affect EI. The study recommended that emotional capabilities should be encouraged and thought in the training of construction professionals both academically and professionally since all construction projects have elements of emotion throughout the life of the project.
