Design Concept
According to Ben van Berkel, “The philosophy behind the Raffles City concept is to integrate mixed use in an urban context, but in such a way as to give this concept a twist; by focussing on where the urban context meets the landscape of the city. In the design of the towers the urban element of the project twists towards the landscape, whilst the landscape aspect, in turn, twists towards the urban context, thereby effecting the incorporation and consolidation of these separate elements in one formal gesture.”
Construction Supporting
Raffles city tower was consisted by using the central core tube and peripheral frames
Reinforced concrete core wall material. In order to meets the requirement of the building's complex facade, the peripheral frame tilt in different directions along the curved facade, forming a unique curve shape. However, this unique shape makes the construction design become extremely difficult. As the frame is parallel shifting on every floor, the pressure and forces make the columns into a harmful situation.
By using 3D modelling software, testing the building's supporting parts and high pressure zones. After the model test, base on the data collected, with certain levels, the pressure produced is over the limit of the supporting frames, as the result, those floors required an appropriate increase in the ratio of reinforcement, in order to prevent cracking or pulled concrete shear damage.
Sustainability
The incorporation of natural ventilation principles and the ways in which materials are employed, all work in concordance with one another to lower the energy and material demands of the building. Urban sustainability is also an important consideration in the design. The program mix creates a dynamic, continuous 24/7 cycle of activity, a hub for business conduct, a new destination for visitors and residents alike and will become an all-in-one destination for working, living, leisure and entertainment.
