Reaching new heights in the use of concrete prefabricated prefinished volumetric construction (PPVC) :Two 56-storey residential towers in Singapore

Abstract

To reduce the reliance on foreign workforce and raise construction productivity, the Singapore building industry is encouraged to embrace the concept as per Design for Manufacturing and Assembly (DfMA) [1] whereby a substantial portion of construction works is done off-site in a controlled manufacturing environment. Prefabricated Prefinished Volumetric Construction (PPVC) modular system is one such technology that significantly reduces on-site manpower requirement and speed up construction. This paper outlines the pioneering & innovative PPVC technology of using a patented reinforced concrete composite structural wall system for construction of two 56-storey residential towers. Prototype sample tests such as compression test and shear tests had been carried out to verify the performance of this wall system; the test results show that this sandwiched combined wall system is able to perform under the actions of bending and shear in a composite manner satisfactorily. This development is currently the world’s tallest residential building project constructed using the reinforced concrete modular construction technology.
