Prefabricated Assembly-Type Housing in Shenzhen
The development of prefabricated assembly-type housing in Shenzhen is mature, covering technical scoring, advanced construction models, policy support, and multi-scenario applications.
1. A Comprehensive Technical Scoring System
Shenzhen has established detailed technical scoring standards for prefabricated concrete buildings and steel structure buildings, evaluating them on a per-building basis (above outdoor ground level). The scoring covers key technical aspects such as standardized design, main structural engineering, and enclosure walls and interior partitions, with minimum score requirements set. For example, standardized design must meet indicators such as component versatility and standardized connection nodes; main structural engineering requires evaluation of the proportion of prefabricated components and construction accuracy; enclosure walls and interior partitions must comply with requirements such as non-masonry and plaster-free finishes. The total technical score must reach a certain standard to be recognized as a prefabricated building, ensuring project quality control.
2. Innovative Construction Models Enhance Efficiency
Shenzhen has taken the lead in promoting the MiC (Modular Integrated Construction) model, which completes over 90% of the structural, decoration, and equipment pipeline work of building modules in the factory, requiring only tower crane hoisting and assembly on-site, achieving construction “like building with LEGO bricks.” For example, after adopting the MiC model in a certain affordable housing project, the construction period was shortened by 50%, and on-site wet work was reduced by 80%, significantly improving construction efficiency and environmental performance. Additionally, Shenzhen has explored technologies such as the “sky-high building machine” and “integrated prefabricated decoration,” driving the upgrading of building industrialization.
3. Policy-Driven High-Quality Industry Development
The Shenzhen Housing and Construction Bureau issued the “Administrative Measures for the Construction of Prefabricated Building Projects in Shenzhen,” clarifying full-process management requirements from design to construction and acceptance, and strengthening quality supervision. At the same time, national and local policies continue to intensify support, such as providing floor area ratio incentives, tax and fee reductions, and financial subsidies for prefabricated building projects, and requiring government-invested projects to prioritize the use of prefabricated technology. The combination of policies effectively stimulates market vitality and promotes a year-on-year increase in the proportion of prefabricated buildings.
4. Diversified Expansion of Application Scenarios
Prefabricated buildings are widely used in Shenzhen for projects with high standardization, such as affordable housing, apartments, hotels, schools, and hospitals. For example, a talent housing project in Longhua District achieved “start and top-out in the same year” through prefabricated technology; a hotel in Nanshan District adopted a steel structure prefabricated system, shortening the construction period by six months. These projects, through standardized design, industrialized production, and prefabricated construction, balance efficiency and quality, providing strong support for urban renewal and housing security.
Shenzhen has built a full industrial chain development ecosystem for prefabricated buildings through technical standard leadership, innovative model breakthroughs, precise policy support, and in-depth scenario applications, providing a demonstration model for the national transformation of building industrialization.
