Floating Environmental Deck Structures—Design Construction Challenges

Grand waterfront living is popular throughout the world including Singapore. The Reef at King’s Dock (RKD) condominium project, featuring a 180-m-long floating sundeck with swimming pools, promises to provide residents and guests a spectacular seaside experience. The prestressed concrete pontoon-based floating structure has a design life of 50-year with minimum maintenance. The RKD floating sundeck is 180 m long, 11.7 m wide, and assembled using three separate 60 m long concrete modules end to end. The module depths vary from 5.0 to 5.2 m. The structure is designed to float in water depth of 8.3 and 12.5 m in low and high tide, respectively. The floating sundeck is cast off-site and towed to its final location. The whole sundeck is targeted to be completed in 2024 and will become the region’s first floating swimming pool and one of the largest concrete floating structures in the region.
