Performance rating of contractors is very important to both the client and contractor especially in an emerging construction industry like the Ghanaian construction industry. Indeed, previous studies internationally have indicated that the development of a set of measurable criteria is key to performance rating. In the absence of any empirical data for legitimizing performance assessment in the Ghanaian Construction Industry, this book provides a set of criteria that could be applied in rating contractor performance in the Ghanaian construction industry. A survey was conducted in Ghana among professionals to identify a set of performance criteria that many think would be relevant and applicable for assessing the performance of contractors in the Ghanaian construction industry. Though, this book is based on the opinion of consultants within the industry, it is expected that the findings of this book could be relevant for future policy guidelines for rating contractor performance in Ghana.
