Critical success factors influencing project success in the construction industry

English: The construction industry is one of the largest job creators in developing countries and is highly competitive. The high number of project failures suggests the existence of underlying critical success factors which have not been identified. This article assesses the perceptions of contractors and project managers on the critical success factors that lead to project success in the construction industry. This article is based on the four COMs model (comfort, competence, communication and commitment). A survey was conducted among 95 project managers and 61 active grade four contractors in Durban, South Africa. The findings reveal that both project managers and contractors strongly support the identified critical success factors as significant in achieving project success. There was no significant difference in their perception of critical success factors, based on the biographic characteristics. The recommendations presented may be used as a guideline for successful execution of construction projects.
