Prefabricated Houses for High-Rise Buildings

Prefabricated houses can be used to construct high-rise buildings and offer significant advantages.

I. Construction Method and Efficiency
Prefabricated houses adopt a modular construction approach, where walls, floors, utilities, and finishes are completed in the factory, with only module assembly required on-site. For example, in Chinese smart factories, it takes an average of two days to complete one floor from lifting to precise placement of modules. For a 16-story building, the assembly of 298 modules takes only 120 days to be ready for delivery, reducing the construction period by 60% compared to traditional methods. The 16-story residential building in Abu Dhabi, UAE, was even assembled with 259 module units in just 96 hours, demonstrating extremely high construction efficiency. This 'factory prefabrication + on-site assembly' model significantly reduces on-site work time, making it particularly suitable for projects with strict deadlines.

II. Structural Forms and Applicability
Prefabricated houses for high-rise construction mainly come in three forms: steel, concrete, and timber. Chinese companies have comparative advantages in steel and concrete structures:

1. Steel Structure: Lightweight and high-strength, suitable for ocean transportation and high-rise buildings. Its modular design allows for flexible combination to meet different height and functional requirements, while also facilitating disassembly and reuse.
2. Concrete Structure: Enhances seismic resistance through steel-concrete integrated pouring technology (such as CMC composite modular construction), reducing the construction period by 30% compared to traditional methods. Concrete modules offer excellent durability and fire resistance, making them suitable for high-rise buildings with high structural safety requirements.
3. Timber Structure: Although advantageous in terms of environmental protection and construction speed, it is currently less prevalent in high-rise buildings due to material strength and fire code limitations, and is mostly used in low- to mid-rise buildings.

III. Technological Advantages and Case Support
The core advantage of modular construction lies in standardized production and precise assembly. Taking CMC composite modular construction as an example, steel-concrete integrated pouring technology ensures component quality through factory production, with on-site assembly errors controlled to the millimeter level, significantly improving overall building stability. Chinese companies have accumulated technological expertise covering the entire chain of design, production, transportation, and installation. For instance, the Abu Dhabi project achieved seamless integration of transoceanic transportation and rapid assembly through optimized module design, providing a replicable model for global high-rise prefabricated construction.
