Surface and Subsurface Utility Database and Mapping: UiTM Shah Alam

Abstract

Rapid urbanization needs detail planning to optimize the land use to provide facilities to people. As urban growth, the use of land is shifting from the use available space above ground (surface) to the use of underground (subsurface) spaces. Many have not realized the significance of subsurface utility mapping which is vital as reference before starting any excavation work. Incomplete information about the location of the buried subsurface utilities may cause unwanted incidence to happen and make it difficult for upgrades and maintenance works to be done. In order to provide readily, reliable and up-to-date utility data it is necessary to have a centralized database that combines all utility data. Therefore this study is conducted to propose a utility database to Facility Management of UiTM Shah Alam in storing, maintaining, monitoring, updating and easy to retrieved surface and subsurface utility data that installed inside UiTM Shah Alam area. Data used in this study focuses on Electrical, Telecommunication and Water Supply utility which was obtained from Facility Management of UiTM Shah Alam in form of a digital utility mapping plan separately. As the final product of this study is a database that will have various advantages in future use, SaS Utility Database has been developed based on Underground Utility Mapping Circular prepared by JUPEM and has been applied MS1759 standard attribute for each data to allow data sharing effectiveness in between organizations. Apart from that, to ensure the data stored in the database is at its best, topology analysis has been run by sets 3 types of rules for each utility category to detect any error that may occurs during digitizing or conversion stage. The findings of this study is with the SaS Utility Database, all utility data stored in a database can be secure, manipulate and converted in various formats depending on its purpose in order to create new information or knowledge as well it will enhance the work process in the future in terms of data sharing with other organization.
