Zhejiang Prefabricated Modular Housing

Zhejiang Prefabricated Modular Housing, represented by Building 7 of Phase I of the Jiaxing Baibu Project, showcases the achievements of combining efficient construction with technological innovation. The following provides an introduction from four aspects: project case studies, technical features, construction advantages, and related enterprises.

I. Typical Project Case Study
Building 7 of Phase I of the Jiaxing Baibu Project is the first high-rise concrete modular building in Zhejiang Province and the first integrated concrete modular building with an assembled monolithic shear wall structure nationwide. The project commenced in September 2023 and was completed in February 2024, with a construction period of only 154 days, more than half shorter than traditional methods. Upon delivery, the project will provide 378 dormitory rooms, accommodating over 1,500 people, demonstrating the applicability of modular construction in high-rise residential buildings.

II. Core Technical Features

1. Innovative Structural Connections: Vertical grout sleeves are used to connect prefabricated shear walls, ensuring the stability of the main structure. High-strength concrete beam molds, combined with connecting reinforcement, enhance the load-bearing capacity of components. The roof uses ordinary concrete composite slabs, with bottom reinforcement and truss reinforcement to strengthen overall integrity.
2. Lightweight Partition Walls and Integrated Finishes: Partition walls are made of ALC panels or lightweight concrete, reducing the building's self-weight. Integrated bathrooms are molded from new composite materials, achieving integration of structure, finishes, and piping.
3. High Assembly Rate Technical System: The prefabrication ratio of vertical components in the main structure reaches 47.48%, with an assembly rate of 91.4%, meeting Zhejiang Province's 'AAA' level prefabricated building standards. Applied technologies include aluminum alloy formwork, composite floor slabs, prefabricated stairs, and integrated insulation and decoration panels, covering the entire process from main structure to finishes.

III. Construction Advantages

1. Significantly Reduced Construction Period: Modular construction technology reduces the project duration by more than 50% compared to traditional methods, with the Baibu Project completing the entire process from start to finish in 154 days.
2. Lower Labor Costs: On-site labor is reduced by more than 70%, with factory-prefabricated components minimizing on-site operations and improving construction efficiency.
3. Enhanced Quality Control: Factory-standardized production combined with on-site assembly reduces human errors, ensuring the stability of building quality.
