Adjacent structure, Risk Management, BIM, Mobile web service, Urban Underground
During the urban underground construction, control of behaviours and assessment of hazards to adjacent structures right at the sites can be extremely difficult owing to processing data from various types of monitored instruments corresponding to multiform of building structures. In this paper, a novel mobile web-based comprehensive information system, named MitiRisk, which is combined from building information model – BIM, mobile web service technology to be presented. In the proposed system, building information model is applied to visualize the current situation of monitoring building structures, whereas, mobile web service technology is used to enable effective necessary data exchange in real-time. Testing examples of the developed system to the O6 station’s excavation in Kaohsiung metro system in Taiwan and application scenarios in Metro line 1 (Ben Thanh – Suoi Tien) in Ho Chi Minh metro system in Vietnam, are presented to illustrate the improvements of safety management to adjacent structures in urban underground construction projects.
