The main aim of this study is to identify the significant factors for contractor selection in Ghana using factor analysis. The study was also to find the preferred criteria for evaluation and selection of contractors in Ghana. The study identified 67 variables used in evaluation and subsequent selection of contractors. Using factor analysis, it was determined that the variables had common underlying factors. The significant factors determined after reduction were five, namely: Managerial factors, Quality and Standards factors, Resource Availability factors, Duration and Cost factors and Location factors. It was also revealed that Ghanaian construction professionals prefer multi-criteria selection of contractors to single criteria and would also allocate higher marks to technical evaluation than to financial evaluation in selecting a contractor for a project. However, very few of them know about modern multi-criteria selection methods such as Analytical Hierarchy Process, Analytical Network Process, Evidential Reasoning, etc, developed by researchers for multi-criteria selection.
