Due to the shortage of workforce and limited land use, many cities like Hong Kong is heading to the direction of improving construction efficiency by adopting more efficient construction method such as DfMA to building high-rise buildings. The traditional prefabricated/precast 2D construction is now being migrated to prefabricated prefinished volumetric (3D) construction (PPVC), whereby free-standing volumetric (3D) modules, completed with finishes for walls, floors and ceilings, are constructed and assembled at site. However, PPVC is not commonly used in high-rise buildings because of the joints’ flexibility as well as stringent requirement for manufacturing and construction tolerance, which have significant impact on the overall stability of the building. This seminar highlights the existing challenges of PPVC of high-rise buildings and provide pointers to address these challenges. Firstly, the weight of a module is constrained by the transportation and lifting crane capacities. For this reason, lightweight cementitious material is introduced together with structural steel section to form lightweight steel-concrete composite system 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 design 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. The seminar will discuss several projects that utilise PPVC technology for multi-storey construction. The construction of concrete and steel modular multi-storey buildings using grouted wall panels or bolted steel components and semi-rigid joints will be presented to illustrate the benefit of prefabrication technology.
The seminar provides essential information to engage the design team, contractors, and owner to plan for prefabrication in the design phase. After the seminar, the participants should be able to
• Recognize opportunities to implement a prefabrication strategy in different project delivery methods
• understand how BIM plays an important role in early decision making, collaboration, and coordination of multiple trades
• understand the potential cost savings and productivity increase when implementing modular construction
• Learn how to design for modular construction and understand how to implement it successfully
• Learn from projects that adopt modular construction for multi-storey buildings.
