Assessing Governance Issues of Underground Utility As-Built Records

Insufficient management to underground utilities often appears as frequent and disorganized street works, unduly prolonged excavation period and underground properties damage. A centralized utility information system can facilitate utility information to share, update and exchange and has irreplaceable advantages in managing underground space. In order to fully utilize a utility information system, the fundamental component-utility as-built records must be complete, accurate and reliable. However, currently, the data quality of as-built records in many cities remain unsatisfactory, which also obstructs the process of building "Smart City". The purpose of this paper is to investigate governance issues with as-built records in worldwide cities, in order to provide insight to current manage mechanism. The findings indicate that proper governance and management should be carried out to improve the data quality of as-built records in the long run.
