Challenges Faced in Training Expatriate Managers

The training to the expatriate shall be conducted both before leaving the home country and after arrival in the host country. Both hard skills and soft skills training shall be conducted before the assignee leaving the home country. The hard skills are technical areas that are specific to the assignee’s job.

Off-site construction and pre-fabricated units (PODs)

In order to reduce the project duration, off-site construction methods were adopted in this project with pre-fabricated components to increase efficiency, schedule and quality.  There were 80+ patient bathroom and shower pre-fabricated units (PODs) in the south expansion of The Christ Hospital Joint and Spine Center. As the PODs were fabricated in the factory, it minimize the impact from weather, which was always a critical factor delaying project schedule, especially for outdoor installations during harsh weather conditions. The fabrication in factory made it easier for the workers to work around the PODs with all available tools and enough working spaces, which eased the production process. There were also benefits from the inspection and quality control that can be conducted in the factory to clear the defects in the early stage. There should be risk assessment implemented for a project. Risk in the areas such as safety, schedule, human resources, finance, etc., should be c...
