Project Success Evaluation Criteria of Construction Project Stakeholders in Kenya

Abstract

The formal practice in the Kenyan construction industry has been to evaluate project success based purely on the Time, Quality and Cost (TQC) criterion leading to incomplete and misleading assessments. The study discovered other evaluation criteria that are inherent in the Kenyan construction industry that included the organizational benefits, user benefits, project team members' benefits, the Iron-Diamond, and the social benefits success criteria. A questionnaire consisting of both structured and open-ended questions was sent to 380 randomly selected project stakeholders who comprised of 57 consultants, 26 project sponsors, 252 contractors, and 45 project managers. In the case of consultants and project managers, the sample frames were obtained from their respective professional bodies; and in the case of project sponsors and contactors from the National Construction Authority (NCA). Out of the 380 questionnaires that were sent, 239 questionnaires were returned (42 consultants, 157 contractors, 34 project managers and 6 project sponsors) representing a response rate of 62.9 %. The study employed a mixed method research of the convergent parallel design and a research philosophy that combined two perspectives: ontological realism and epistemological post-positivism.
