Opportunities and challenges of using Pre-Fabricated Pre-Finished Volumetric Construction (PPVC) for high-rise construction
Singapore has been continually striving to improve productivity in the construction industry. In 2015, the Building and Construction Authority (BCA) rolled out the 2nd Construction Productivity Roadmap to push the industry to adopt game-changing technologies and the adoption of innovative building methods. One of which is Design for Manufacturing and Assembly (DfMA) which include Pre-Fabricated Pre-Finished Volumetric Construction (PPVC). PPVC has been encouraged and even stipulated in government land sale which leads to more projects and taller buildings adopting such construction techniques. While there are benefits from this construction technique for example higher efficiency, reduced manpower on site, better construction quality, there are also many challenges which include procurement, higher cost, intellectual property protection, safety in lifting, tighter tolerances etc.
This paper looks into the various opportunities and challenges in the use of PPVC for high-rise construction. Some projects are used for the illustration. There are many lessons learnt and improvements made as the technology is used more.
