Tunnelling and Underground Space Technology

Utility tunnel should be well maintained for it services public pipelines and city operation. In the recent time, utility tunnel has been operated via computer maintenance management systems (CMMS) or building automation systems (BAS). However, CMMS or BAS lack of convenient visualization and interoperability. This paper aims to propose an integrated system of building information modelling (BIM) and geographic information system (GIS) to improve the performance of current maintenance management system. A system framework of BIM-3DGIS is proposed and required maintenance management functions are also developed based on practice demands. A real case of utility tunnel is used to demonstrate the system. Two scenarios and a questionnaire survey are conducted to validate the applicability and practicability. Results show that the proposed BIM-3DGIS system can ensure effective maintenance works and have well potential applications.
