Assessing lean construction conformance amongst the second-grade Jordanian construction contractors

This study aims to investigate the level of the conformance of the practices of the second-grade contractors with lean construction principles. This study adopted the descriptive and quantitative design by using a questionnaire to investigate collect data. Seventy-two respondents from the second-grade contracting companies in Jordan participated in the study. The results showed that the conformance of the practices of these companies with the principles of lean construction was less than 65%. Also, the study showed that amongst the principles of lean, customer focus was the most applied in these companies, and showed that these companies lack the culture of providing training and empowerment to their employees and the culture of continuous improvement. This study will help to expand the knowledge about the lean construction application in Jordan, and to investigate the level of the application of this philosophy in different types of projects and different sizes of companies. The results of the study might be applicable in similar environments to Jordan.
