Abstract

Delay is one of the most common and complex issues that adversely affect the performance of construction pro-jects. Although much research exists on project delay, only some studies have systematically summarized and compared the causes of delay by the project type. In addition, few studies have quantitatively combined the variability across studies and related them to the responsibilities of project stakeholders. This study conducted a meta-analysis to provide quantitative and reliable evidence on delay causes combining previous research. This study categorized the top ten causes of delay published in primary research studies, calculated the average aggregate relative important index (RII) of these causes, quantitatively summarized their impact on building and road projects using meta-analysis techniques, and linked them to stakeholder responsibility. Based on an initial 160 top ten-delay causes reported, the study aggregated them into sixteen factors and seven management areas. This research found a different prioritization of delays by project type. Overall, while "site management & technical processes" was the most critical delay factor for building projects, "external issue" was for road projects. The comparison by region shows that "skills, knowledge & experience" was the most critical factor for African studies, but "late delivery and material-equipment issues" was for Asian studies. These factors were related to project stakeholders for defining mitigation actions that led to better project performance. Finally, this study provides a first taxonomy of delays, where the previous causes reported in the literature were clustered into factors and management areas.
利益相关者的问题是项目延迟的根源:建筑和道路项目之间的元分析
延迟是影响建设项目绩效的最常见和最复杂的问题之一。虽然有很多关于项目延迟的研究,但只有一些研究系统地总结和比较了项目类型延迟的原因。此外,很少有研究定量地将研究之间的可变性结合起来,并将其与项目干系人的责任联系起来。本研究结合前人研究进行meta分析,为延迟成因提供定量可靠的证据。本研究对主要研究中发表的十大延误原因进行了分类,计算了这些原因的平均总相对重要指数(RII),使用元分析技术定量总结了它们对建筑和道路项目的影响,并将它们与利益相关者责任联系起来。根据最初报告的160个十大延迟原因,该研究将其汇总为16个因素和7个管理领域。这项研究发现了不同项目类型的延迟优先级。总体而言,“现场管理和技术流程”是建筑项目最关键的延迟因素,“外部问题”是道路项目最关键的延迟因素。各区域的比较表明,“技能、知识和经验”是非洲研究的最关键因素,而“交货迟和材料设备问题”是亚洲研究的最关键因素。这些因素与项目利益相关者有关,以确定导致更好项目绩效的缓解行动。最后,本研究提供了延迟的第一个分类,其中先前文献中报道的原因被聚集到因素和管理领域。

期刊介绍: The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
