This 135m tall, 45-storey tower is a pioneer of modular building and the tallest of its kind in the world.
The building takes the form of two different height towers. 1526 volumetric steel modules were installed on a concrete transfer structure at first floor level over two levels of basement. A concrete core provides lateral stability to the building. The engineers designed several innovative connections to accommodate the differential vertical movement between the modules and the core.
The towers were installed in just 35 weeks, with a total construction programme of 28 months. In addition to the cost savings associated with a reduced programme, the modular system minimises environmental impact with 80% less construction waste, 50% less CO2, 80% less vehicle movements to site and 60% less personnel.
This pioneering modular concept could solve many future residential building demands around the world.
