Abstract
The construction industry is increasing in size, technology complexity, interdependencies, and variations in demands from clients. It is of huge significance for an organisation to analyse and identify how well it is performing, and to know the appropriate catalyst that stands to be utilised, to ensure ultimate performance. However, the purpose of this paper is to determine whether there is a difference in the perception of consultants and contractors on the factors affecting the performance of construction projects. The methodology adopted in this research was a quantitative research approach. Data was collected using a questionnaire. The questionnaire aimed at 60 respondents which were civil engineers, quantity surveyors, construction managers, architects, project managers and contractors. Result from the findings revealed that consultants see conformance to specification being more important whereas contractors see, late payment from owner to contractor being more vital.
