This major mixed-use development located on Orchard Road in Singapore, a prime shopping area, offers 56 stories of luxury apartments and 710,500 square feet (66,000 square meters) of retail space. The development was constructed using advanced techniques that allowed this complex project to be completed within 18 months for the first phase, and 30 months for the entire project.

WSP provided civil and structural design consulting services for the project. An unusual top–down construction method, with extensive use of precast elements to reduce construction time, was employed for construction of the 56-story residential apartment complex. The development, which is integrated into the existing mass transit station, also uses a unique transfer system known as mega-trusses—the first for a commercial development in Singapore—comprising multiple long-span steel trusses with a structural depth of over four floors.
