Abstract
As the symbol of Kuala Lumpur City Centre Project, twin towers have been constructed, and each of twin towers (Tower One & Tower Two) has 88 floors. The complex structure of this tower consists of external tube with reinforced-concrete columns and beams, and steel frame beams connecting the columns and beams to the internal reinforced-concrete core-wall. The high-strength concrete of 80 MPa is designed for the structural members. The construction of this tower should be finished in 29-months, therefore the high-speed construction method have been achieved at rate of one floors in four days, by working day and night. This report describes the outline of this structure, construction method and quality control of high-strength concrete.
