Announcement of Shenzhen Prefabricated Housing Plan
The announcement of the Shenzhen prefabricated housing plan mainly covers aspects such as technical systems, project scale, module design, construction deployment, management mechanisms, and policy guidance, as detailed below:
Technical Systems and Project Scale
Shenzhen's prefabricated housing predominantly employs the Concrete Modular Integrated Construction (C-MiC 2.0) technical system, centered around standardized modular units. For instance, the staff dormitory project in the Fucheng South Industrial Area of Longhua District has a total construction area of 42,600 square meters, with 2 underground floors, 28 above-ground floors, and a building height of 98.6 meters, divided into 728 modular units. Module design emphasizes functional integration, with each module being an independent hexahedral structure that integrates an entrance foyer, bathroom, bedroom, and balcony. The dimensions are uniformly 3.6m × 7.2m × 3.2m (width × length × height), and the weight is controlled at 25-30 tons per module to ensure transportation and lifting efficiency.
Construction Deployment and Management Mechanisms
Construction adopts the EPC (Engineering, Procurement, and Construction) general contracting model, with distinct departments established for design, factory manufacturing, logistics and transportation, on-site installation, and technical research and development, ensuring clear division of labor. The site is divided into lifting operation areas (equipped with intelligent monitoring systems), module stacking areas (6 zones, each with a capacity of 24 modules), and material processing areas. The total construction period is typically 180 days, implemented in stages: factory prefabrication (30 days), on-site lifting (90 days), mechanical and electrical installation and decoration (30 days), and final acceptance (30 days). The management mechanism requires the construction unit to coordinate all participating parties, allocate management personnel with training certificates, and ensure that key trades (such as component lifting and sleeve grouting) complete pre-job training and assessments to guarantee construction quality.
Policy Guidance and Standard Systems
Shenzhen promotes prefabricated decoration, with government-invested projects (such as affordable housing and talent apartments) fully adopting it, and pilot full decoration delivery for commercial housing, while encouraging its application in existing building renovations. The policy emphasizes improving design, production, construction, and acceptance standards, promoting dimensional guidelines for components and parts, and key scenario atlases to enhance standardization levels. For example, prefabricated building projects must specify the types of prefabricated components and their technical scores, and structural design must explain key nodes (such as the connection methods of prefabricated components) to ensure structural safety and durability.
The content of the above plan announcement is subject to the final official document, and specific project implementation should adjust technical parameters and management processes according to actual needs.
