Contemporary construction companies are placing emphasis on implementing various safety and health strategies in order to attain a favorable safety climate within the industry and enhance operational effectiveness. The purpose of this study is to examine the influence of operational safety (OS), health performance (HP), and safety preparation (SP) on the project performance of construction companies in Saudi Arabia. In order to effectively accomplish the stated objectives and yield optimal outcomes, data was gathered from a sample size of 316 employees employed in construction companies. The findings of the study emphasize that operating systems (OS), human resources practices (HP), and strategic planning (SP) have a significant influence on the project performance of construction companies. The mediation of open-source software (OSS) has demonstrated significant effects on the relationships between operating systems (OS), hardware providers (HP), software providers (SP), and platform providers (PP). This study renders a valuable contribution to the existing body of knowledge on safety by investigating the effects of pertinent factors within the construction industry. The results of this study provide valuable insights for professionals in the construction industry, enabling them to enhance the efficacy of safety management systems within their respective work environments. Furthermore, it serves as a driving force for the development of programs and policies aimed at facilitating the effective implementation of operating systems (OS), scheduling practices (SP), and health and safety protocols (HP) in order to attain optimal performance in construction projects.
