Over the past decades, construction delays have been perceived as a global challenge that hinders the time delivery, budget, and quality of construction projects. It is the most common, expensive, and risky problem associated with both private and public construction projects. Within this context, the aim of this study is to investigate the significant factors that influence delays in construction projects in Hargeisa, using the road and building projects as a baseline. Through a questionnaire survey with 51 critical delay factors that are categorized into seven major groups, data were collected from 51 construction stakeholders selected based on simple random sampling from the different construction companies. Feedback from the respondents was analyzed using Relative Importance Index (RII) for ranking purposes. Results showed that delay in honoring payment progressively, underestimation or overestimation of the project cost, and delay in the approval of major changes in the work scope were ranked as the three major causes of delays in construction projects in Hargeisa. The implications of these results are vital to future projects as they clearly demonstrate how less attention is given to the application of project management tools such as robust cost, scope and risk management in construction projects. As such, construction stakeholders are recommended to make efforts to use the appropriate project management practices needed to manage the 16 identified critical delay factors, when executing future construction projects. Although, the current study focused on Somaliland construction projects, it expands and improves the understanding of delay factors in the global context, and as such can be applied to other countries and future studies.
在过去几十年里，施工延误被视为一项全球性挑战，它阻碍了建设项目的按时交付、预算和质量。这是与私人和公共建设项目相关的最常见、最昂贵且风险最大的问题。在此背景下，本研究旨在以道路和建筑项目为基准，调查影响哈尔格萨建设项目延误的重要因素。通过对51个关键延误因素进行问卷调查（这些因素分为七个主要类别），从不同建筑公司通过简单随机抽样选出的51名建设利益相关者那里收集了数据。使用相对重要性指数（RII）对受访者的反馈进行分析以进行排名。结果表明，付款延迟、项目成本的低估或高估以及工作范围重大变更的批准延迟被列为哈尔格萨建设项目延误的三大主要原因。这些结果的影响对未来项目至关重要，因为它们清楚地表明了在建设项目中对诸如稳健的成本、范围和风险管理等项目管理工具的应用关注较少。因此，建议建设利益相关者在执行未来建设项目时努力采用管理已确定的16个关键延误因素所需的适当项目管理实践。尽管当前研究聚焦于索马里兰的建设项目，但它在全球背景下扩展并增进了对延误因素的理解，因此可应用于其他国家和未来研究。
