Hong Kong's transport infrastructure comprises many viaducts for both road and rail transport purposes. There are different viaduct construction methods, all of which involve complicated processes such as site formation, excavation, lifting, falsework erection, lifting frame erection, concreting, re-bar fixing, box girder fabrication, pre-stressing, and many other associated work activities. Nowadays, the main structures of viaducts in Hong Kong are commonly constructed with pre-cast segments and the efficiency of the construction processes is also enhanced with massive application of mechanized lifting operations. However, these operations also bring about different risks which could compromise the site safety and may lead to serious consequence if they are not managed properly.

This course is designed for managers, supervisors, workers and other technical personnel working on viaduct construction projects. The course aims to provide participants with knowledge of risks associated in construction processes of viaduct and respective control measures so as to increase their safety awareness and reduce their risk of injury.
