This study examines the causes of time delays and cost overruns in a selection of thirty post-disaster reconstruction projects in Iraq. Although delay factors have been studied in many countries and contexts, little data exists from countries under the conditions characterizing Iraq during the last 10-15 years. A case study approach was used, with thirty construction projects of different types and sizes selected from the Baghdad region. Project data was gathered from a survey which was used to build statistical relationships between time and cost delay ratios and delay factors in post disaster projects. The most important delay factors identified were contractor failure, redesigning of designs/plans and change orders, security issues, selection of low-price bids, weather factors, and owner failures. Some of these are in line with findings from similar studies in other countries and regions, but some are unique to the Iraqi project sample, such as security issues and low-price bid selection. While many studies have examined factors causing delays and cost overruns, this study offers unique insights into factors that need to be considered when implementing projects for post disaster emergency reconstruction in areas impacted by wars and terrorism.

这项研究研究了伊拉克30个灾后重建项目中的时间延迟和成本超支的原因。尽管已经在许多国家和地区研究了延迟因素，但在过去10至15年中，在伊拉克为特征的条件下，各国的数据很少。使用了案例研究方法，从巴格达地区选择了三十个不同类型和规模的建筑项目。项目数据是从一项调查中收集的，该调查用于建立灾难后项目中时间与成本延迟比率和延迟因素之间的统计关系。确定的最重要的延迟因素是承包商故障，设计/计划和变更单的重新设计，安全问题，低价投标的选择，天气因素和业主故障。其中一些与其他国家和地区的类似研究结果相一致，但其中一些是伊拉克项目样本所独有的，例如安全问题和低价竞标选择。尽管许多研究已经研究了导致延误和成本超支的因素，但这项研究提供了独特的见解，以了解在受战争和恐怖主义影响的地区实施灾后紧急重建项目时需要考虑的因素。
