Abstract:
Basement has become very popular for modern civil construction in Vietnam as 60% of the civil building of the country has more than two basements. However, many projects find it extremely risky to execute earthwork, especially with the depth of more than three basements. It is therefore very important for developers, designers, and constructors to study risk management in deep basement earthwork/excavation.
Risk happens in all aspects of an earthwork project, the problems could lead to cost overhead or waste of time, and it can even result in physical hazard to worker, including injuries, serious damages or even death. From the demand for knowledge of earthwork risk management, this study develops an advance framework to control risk in an earthwork projects. It consists of risk counter in all stages of the project. This study covers four earthwork stages, including 'Acquiring, Ignition, Execution and Closure'.
There is a gap between theories and practice in Vietnam because of the lacking formal risk management system in deep excavation work. Therefore, this research outlines some of the risk management theory but mainly focus on analyzing the practice of a real life project, which contains the excavation of six basements. As a result from this study, some recommendations will be given to improve the knowledge of Risk Management System for Deep Basement Earthwork/Excavation.
