The purpose of this research is to examine the causes of delay in airport projects in general and the King Abdulaziz International Airport (KAIA) of Saudi Arabia in particular. The KAIA is the most strategic and busiest airport of Saudi Arabia, which transports millions of pilgrims from two hundred countries to perform Hajj and Umrah in Makkah. In general, more than 50% of construction projects fail on one more area. Our method of research is empirical based on the analysis of responses received from seventy-one respondents to our survey questions. We shall also synthesize literature that utilizes previous research and case studies on aviation and public project failures. We believe that this research will be valuable in ascertaining and mitigating direct causes for the numerous project delays in Kingdom of Saudi Arabia.

本研究的目的是检查机场项目延误的原因，特别是沙特阿拉伯的阿卜杜勒阿齐兹国王国际机场 (KAIA)。KAIA 是沙特阿拉伯最具战略意义和最繁忙的机场，它运送来自 200 个国家的数百万朝圣者在麦加进行朝觐和副朝。一般而言，超过 50% 的建设项目在多一个区域失败。我们的研究方法是经验性的，基于对 71 名受访者对我们调查问题的回答的分析。我们还将综合利用先前关于航空和公共项目失败的研究和案例研究的文献。我们相信，这项研究将有助于确定和减轻沙特阿拉伯王国众多项目延误的直接原因。
