ABSTRACT:

The Building industry in Singapore has been adopting a new technology for building construction called Prefabricated Prefinished Volumetric Construction (PPVC) which has gained popularity due to its numerous advantages such as fast track, better quality finishes, reduction in work force and construction waste, etc.  PPVC technology promotes off-site manufacturing of modular units and on-site assembly, improving the construction efficiency and productivity. However, for high-rise buildings, the joints’ flexibility and construction sequence have significant impact on the overall stability of the building. This paper highlights the existing problems of modular construction of high-rise buildings and provide practical solutions to address these problems. Firstly, the weight of a module is constrained by the transportation and lifting crane capacities. For this reason, steel and lightweight concrete composite system is introduced to reduce the weight of the module without compromising the strength and stiffness. Secondly, to speed up the site assembly of modular units, special joints are developed to resist the forces due to gravity and horizontal loads. Fast and easy joining techniques with acceptable tolerance control are essential to ensure the structural integrity and stability of the building. Finally, the innovation for productivity can be maximized by implementing automation technologies in the manufacturing and construction of the modular units.
