The purpose of this paper is to address the primary research question, which is what is the relationship between the project manager’s (PM) possession of the Project Management Professional (PMP) certification and the level of the safety culture present in the construction project the PM manages.,The research was based on a survey of a purposive sample, 109 engineers and first-line supervisors worked in 23 construction projects of which ten were led by PMP-certified PMs and 13 were led by PMs lacking PMP certification. Each PM completed a demographic questionnaire for the predictor variables of PMP certification controlled for age and experience. To assess the criterion variable of safety culture total score, engineers and first-line supervisors working in the same project completed the questionnaire of safety culture values and practices.,Results of this study indicated the level of safety culture was significantly different, and improved, for engineers and first-line supervisors who work under PMs with PMP certification compared to the level of safety culture in projects managed by PMs with no PMP certification. Although alignment of safety culture perceptions among different levels in the organization helps to achieve a positive safety culture, the role of the PM in transferring, implementing and maintaining the safety culture in the construction project is fundamental, particularly in small-to-medium sized enterprises (SMEs).,This study addressed the role of the PMs managerial skills in the safety performance of Saudi Arabian SMEs. The principal finding was that PMs with managerial skills perform better regarding safety performance in SME construction projects than PMs lacking managerial skills. The primary recommendation is that leaders in construction projects must carefully evaluate engineers’ managerial skills before hiring the individuals as PMs. A PM’s promotion model developed in this study provides a suitable framework and business process component for construction leaders seeking to maintain safety performance successfully.

项目经理在沙特建筑安全绩效中的作用

本文的目的是解决主要的研究问题，即项目经理（PM）拥有项目管理专业人员（PMP）认证与建筑项目PM中存在的安全文化水平之间的关系是什么？该研究是基于对目标样本的调查而进行的，共有109名工程师和一线主管在23个建设项目中工作，其中10名由PMP认证的PM领导，而13名由缺乏PMP认证的PM领导。每个项目经理都完成了一份针对年龄和经验控制的PMP认证预测变量的人口统计调查表。为了评估安全文化总分的标准变量，在同一项目中工作的工程师和一线主管完成了安全文化价值观和实践调查表。这项研究的结果表明，与没有PMP认证的PM所管理的项目中的安全文化水平相比，对于具有PMP认证的PM的工程师和一线主管而言，安全文化的水平存在显着差异并得到了改善。尽管组织中​​不同级别的安全文化观念的协调有助于实现积极的安全文化，但PM在建筑项目中转移，实施和维护安全文化的作用至关重要，尤其是在中小型企业中（SME）。这项研究探讨了PM经理的管理技能在沙特阿拉伯SME的安全绩效中的作用。主要发现是，具有管理技能的项目经理在中小企业建设项目的安全绩效方面比缺乏管理技能的项目经理表现更好。首要建议是，建设项目的领导者在雇用个人担任项目经理之前，必须仔细评估工程师的管理技能。在这项研究中开发的PM促进模型为寻求成功维持安全绩效的施工领导者提供了合适的框架和业务流程组件。
