KUALA Lumpur City Hall (DBKL) should establish a comprehensive underground mapping system for city infrastructure and utilities, if it does not already have one, says Institution of Engineers Malaysia (IEM).
IEM president Prof Dr Jeffrey Chiang Choong Luin said the recent sinkhole that swallowed 48-year-old Indian national Vijayalaksmi in Jalan Masjid India highlighted urgent need for action.
