Lucky Plaza, situated along the bustling Orchard Road belt, is one of Singapore’s most iconic mixed-use developments. Like many commercial buildings in this low-lying topographies, the basement levels house essential services, retail outlets, and car park access points that are inherently vulnerable to water ingress. During periods of intense tropical rainfall—particularly the Northeast Monsoon surges—the volume of surface runoff on Orchard Road can overwhelm drainage capacity, creating a risk of ponding and flash floods. FloodX was engaged to mitigate this risk by fortifying the building's vulnerable access points. The primary objective was to implement a defense system that prevents water from entering the basement, thereby protecting valuable assets, mechanical and electrical (M&E) rooms, and ensuring the safety of tenants and visitors.
