Summary: This study investigates the client-related delay factors in recently completed construction projects in Saudi Arabia. The results reveal eight unique client-related causes of delay, with very poor time and cost performance across all projects. These findings can help authorities understand and curb delays caused by clients themselves, and it is recommended to develop these delay factors into a delay risk impact tool.

Summary: This paper examines significant tunnel failures from 1980 to 2019 and creates a comprehensive database including critical parameters. The study finds that the implementation of a risk management code has positively impacted tunnel incidents. Furthermore, an edit distance model is used to identify similar assessment scenarios and predict the most likely failure type. Through the analysis of the database, estimated insurance loss and project delay can be obtained.
