Evolution of modern mega-buildings in China: innovations and sustainability

China’s construction boom over the past few decades has led to growing demand for high-rise and ‘mega-scale’ buildings. Such structures feature sophisticated building services, unique elevations, seamless connection to infrastructure and high safety levels. Design and construction challenges include hazard mitigation against extreme actions and environments, integrated structural frameworks and facades, complex connections and overall constructional efficiency. Civil and structural engineers add value, enhance engineering efficiency and achieve overall environmental and cost-effectiveness for modern mega-buildings in China. This paper introduces the design and construction of four of such projects. It reviews the evolution of modern mega-buildings, including aspects of integrated engineering design, construction technology, value engineering and overall sustainability.
