Innovative technologies on construction of structures of 100-plus-storey skyscraper and their application

Abstract

Experience on the construction of several 100-plus-storey skyscrapers including Guangzhou West Tower, Guangzhou East Tower, and Shenzhen KingKey Financial Center 100 is described considering the increasingly strong development trend of 100-plus-storey skyscrapers in China. Difficulties in the construction of 100-plus-storey skyscrapers are investigated. Four innovative construction technologies receive detailed de-scription, which are intelligently and entirely-jacked work platform, formwork and suspension scaffolding system ("jacking and formwork system"), multi-function low-carbon concrete, 5D-BIM ("5-dimensional building information modeling"), and safe and rapid vertical transport, as they have found successful applications in ac-tual projects. Popularized systematically as technical achievements, these technologies will significantly influence the construction of similar projects in future, and gain more social and economic benefits.
