 Prefabricated Construction FAQ

1．What is Prefabricated Construction？

Prefabricated construction is a building method in which structural components—such as floor slabs and wall panels—are manufactured in a factory and then transported to the construction site for rapid assembly. This method offers fast construction, high dimensional accuracy, reduced on-site work time, and lower environmental impact, and it is well aligned with the trends of green building and carbon reduction.

2．Are buildings constructed with prefabricated systems strong? How do they perform in terms of fire resistance, seismic resistance, heat insulation, and sound insulation？

  • Structural Strength：
    Prefabricated components are rigorously tested to ensure high load-bearing capacity. For example, the Gu Yue fire-resistant floor slab can support up to 1.6 tons per square meter and has passed the bending test conducted by the National Center for Research on Earthquake Engineering.
  • Fire Resistance：
    Gu Yue lightweight brick walls provide 1 hour of fire resistance for interior applications and 3 hours for exterior applications, while the floor slabs achieve a fire-resistant load capacity of 600 kg／m², meeting high fire safety standards.
  • Seismic Resistance：
    Buildings constructed with prefabricated systems feature a lightweight structural design with excellent seismic performance, capable of withstanding wind and rain conditions equivalent to a Level 17 typhoon.
  • Sound Insulation：
    Gu Yue floor and wall panels achieve a sound insulation rating of Rw53 dB, one of the highest standards in the industry, effectively blocking noise and ensuring privacy.

3． Are buildings constructed with prefabricated systems built faster？Where are the cost advantages？

  • Construction Speed：
    Prefabricated construction uses factory-made components and rapid on-site assembly, reducing construction time to only 1／10 of traditional RC methods. For example, on-site assembly of Gu Yue floor and wall panels takes approximately 1 week.
  • Cost Advantages：
    • Prefabricated construction reduces building costs by 15％ to 25％ compared with traditional RC methods.
    • It minimizes on-site labor and equipment usage, lowering both labor and material costs.
    • It aligns with carbon reduction policies, resulting in lower future carbon-related expenses and further reducing overall costs.
