Owners perspective of factors contributing to project delaycase studies of road and bridge projects in Saudi ArabiaDelays are a major cause for concern in the construction industry both globally and locally in Saudi Arabia. This paper identifies the main causes of delay in infrastructure projects in the holy city of Makkah (Saudi Arabia) and compares these with projects around the rest of the country and other Gulf countries as well. Data were obtained from 49 infrastructure projects that were undertaken by the owner and were analyzed quantitatively to understand the severity and causes of delay. 10 risk factors were identified in this study and these factors were grouped into four categories. The average delay in infrastructure projects in the city of Makkah was found to be 39%. The most severe cause of delay was found to be the land acquisition factor. This highlights the critical land ownership and acquisition issues that is prevailing in Makkah. In addition to this, other factors include contractors’ lack of expertise, haphazard underground utilities (line services), and re-designing. It is concluded that majority of delays were caused from the owner’s side as compared to contractors, consultants, and other project’s stakeholders. This finding was in line with the research findings of the Gulf Countries Construction (GCC) Industry’s literature as well. This study will fill an important practice and research gap for improving the efficiency in project delivery for infrastructure projects in the holy city of Makkah and the Gulf countries at large.autElawi, Ghazi Saad AthsKashiwagi, DeandgcSullivan, KennethdgcKashiwagi, JacobpblArizona State UniversityengPartial requirement for: M.S., Arizona State University, 2015Includes bibliographical references (pages 22-24)Field of study: Constructionby Ghazi Saad A Elawihttps://hdl.handle.net/2286/R.I.3477400Masters ThesisAcademic thesesiv, 32 pages114398301971630348073153833adminIn CopyrightAll Rights Reserved2015TextengineeringConstruction industryDelayRisksRoads and bridgesSaudi ArabiaConstruction industry--Saudi Arabia--Management.Construction industryConstruction projects--Saudi Arabia--Management.Construction projectsConstruction contracts--Saudi Arabia.Construction contracts
