Construction Plan for Zhongjian Prefabricated Houses

The construction plan for Zhongjian prefabricated houses takes modular construction technology as its core, achieving efficient construction through industrialization, intelligence, and green methods. The specific plan and characteristics are as follows:

I. Modular Construction Model

Zhongjian adopts a 'factory prefabrication + on-site assembly' model, breaking down buildings into independent modules (such as concrete modules and electromechanical modules). Integrated manufacturing of structures, electromechanical systems, interior decoration, and exterior finishes is completed in the factory. For example, the three-dimensional factory in Zhongjian Hailong Intelligent Construction Industrial Park delivers 20,000 to 30,000 concrete modules annually through assembly-line production, covering components such as ceilings, walls, and waterproof layers, achieving millimeter-level precision control. After being transported to the site, the modules are quickly assembled into complete buildings using equipment such as tower cranes.

II. Construction Process Optimization

1. Parallel Operations: More than 70% of the processes in the factory (such as steel bar binding, pipeline embedding, and decoration) are carried out simultaneously, shortening the construction period by more than 60% compared to traditional buildings.
2. On-site Assembly: Module assembly only requires connection node processing (such as cast-in-place connections), reducing on-site labor by about 50%. Taking a public housing project in Shenzhen, Guangdong as an example, the assembly of 6,028 concrete modules compressed the construction period from 2.5-3 years to 1 year.

III. Quality Control and Precision Management

1. Error Control: Module production positions steel bars in millimeters, and the factory assembly line achieves millimeter-level precision through technologies such as laser scanning and robot welding, improving the building's waterproofing, sound insulation, and earthquake resistance.
2. Circular Reuse: The module reuse rate exceeds 90%, reducing the full life cycle cost. For example, the Lakeview Mansion project in Singapore achieved integrated structure and decoration through the Prefabricated Prefinished Volumetric Construction (PPVC/PBU) technology, winning the BCA Construction Excellence Award.

IV. Technical Support System

1. Intelligent Construction - MiC Technology: The technology independently developed by Zhongjian Hailong transforms construction processes into synchronous production, covering scenarios such as public housing, campuses, and hospitals, supporting rapid and flexible expansion.
2. DfMA Center: Zhongjian Nanyang has established PPVC/PBU production lines and MEP electromechanical module production lines, expanding modular construction methods and improving standardization levels.

V. Environmental Protection and Sustainability

1. Resource Conservation: Construction waste emissions are reduced by more than 75%, material losses by 25%, on-site electricity consumption by 60%, and water consumption by 66%.
2. Circular Utilization: Modules can be disassembled and stacked, supporting building function adjustments or relocation and reconstruction, extending their service life. For example, domestic public housing projects reduce on-site wet operations through modular design, lowering environmental pollution.

Zhongjian's prefabricated house construction plan integrates the entire chain of design, production, and construction through modular technology, achieving a synergistic improvement in efficiency, quality, and environmental protection, providing a replicable benchmark case for industrialized construction.
