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.
