USING THE DELPHI TECHNIQUE AND EFQM MODEL APPROACH TO BUILD A CONCEPTUAL MODEL FOR CONSTRUCTION PROJECT PERFORMANCE

This study presents a new conceptual framework for evaluating the performance of construction projects, based on an adaptation of the European Foundation for Quality Management (EFQM) model. Although the EFQM model is widely used for quality management and performance evaluation, there have been few studies to date that have used it to measure the performance of projects, which is a very important issue in the construction industry. The EFQM model is designed for organisations, so if it is to be used for construction projects, appropriate modifications are needed. That is, the criteria and attributes of the original EFQM model need to be modified. Therefore, the aim of the study is to develop a new set of criteria and their attributes. The attributes are drawn from previous studies and adapted to construction projects. The set of criteria and their attributes form a conceptual model for measuring construction project performance. The model was validated through semi-structured interviews with 20 experts. The results of the study showed that the conceptual model had five enabler criteria, two result criteria, and 50 criteria attributes. The qualitative and quantitative analysis results of the Delphi technique confirmed the importance of these criteria and their reliability. The results of the study will contribute to promoting the application of the EFQM model in the field of construction project management. In addition, stakeholders can use the model as a tool to evaluate the performance of construction projects.
