Advantages and Disadvantages of Prefabricated Assembly Houses

The advantages of prefabricated assembly houses include improved construction quality, accelerated project progress, and enhanced building quality; the disadvantages include limited design flexibility, higher costs, and susceptibility to leakage in exterior wall panel seams.

Advantages

• Improved Construction Quality: Prefabricated assembly houses utilize standardized factory production of components, which minimizes common quality issues such as wall cracking and leakage, enhancing overall residential safety, fire resistance, and durability. The stable factory environment ensures controllable component quality, providing greater assurance compared to traditional on-site construction.
• Accelerated Project Progress: This construction method is approximately 30% faster than traditional methods. With a large number of components prefabricated in the factory, on-site assembly reduces the time and procedures required, effectively shortening the construction cycle.
• Enhanced Building Quality: With the industrialization of interior finishing, it enables 'receiving packages at home'—immediate installation upon unboxing, ensuring both speed and quality. Industrial production guarantees consistent and stable finishing quality, improving living comfort.
• Regulation of Supply and Demand: It facilitates faster market introduction of properties, alleviating supply shortages. Widespread adoption can reduce construction costs and effectively curb housing prices, contributing positively to the stable development of the real estate market.
• Civilized Construction and Safety Management: By relocating a significant portion of on-site work to the factory, only a small number of workers are needed on-site, greatly reducing the incidence of on-site accidents. Additionally, it reduces noise and dust pollution, promoting civilized construction.
• Environmental Protection and Resource Conservation: Minimal on-site casting reduces health hazards and disturbances to residents. The increased reuse rate of steel formwork and significant reductions in waste, loss, and energy consumption align with sustainable development requirements.
• Excellent Performance: Prefabricated panel buildings are strong, lightweight, and have good resistance to deformation, with excellent seismic performance.

Disadvantages

• Limited Design Flexibility: Architectural design flexibility is constrained, resulting in a monotonous appearance with a prominent conflict between standardization and diversification. It is challenging to meet personalized and complex architectural design needs.
• Higher Costs: The use of more steel results in costs that are 10% to 15% higher than those of brick-concrete structures. This increases construction costs and may not be suitable for projects with limited budgets.
• Susceptibility to Leakage in Exterior Wall Panel Seams: During use, it has been observed that exterior wall panel seams are prone to leakage due to various factors such as construction, affecting the functionality and durability of the house.
• Issues with Integrity and Flexibility: Some argue that these houses have poor integrity and low flexibility, although others point out their good seismic performance, which may be related to different structural designs and construction techniques. However, in some cases, their integrity and flexibility may still require further optimization.
