Guangzhou Prefabricated Component Houses

Guangzhou has witnessed rapid development in the field of prefabricated component houses (prefabricated buildings), promoting their widespread application through policy guidance, strict supervision, and incentive measures.

I. Comprehensive Implementation of Prefabricated Buildings
Guangzhou has incorporated prefabricated buildings into land transfer conditions, explicitly requiring new projects to be planned, designed, and constructed according to this standard. For example, projects in key areas such as the Guangzhou Diwang Machang plot must adopt prefabricated technology, driving the industrial transformation of construction from the source. This measure ensures the large-scale application of prefabricated buildings across the city and enhances the modernization level of the construction industry.

II. Strict Quality Control Process

1. Insurance Mechanism as a Safety Net: Developers are required to purchase 'Quality Potential Defect Insurance' and 'Green Building Performance Insurance', forming a risk-sharing mechanism. If quality issues arise in the houses, insurance companies will participate in accountability, forcing enterprises to strengthen quality control.
2. Third-Party Independent Supervision: Insurance companies entrust TIS institutions to provide full-process risk control services, conducting at least two surprise inspections of concealed works at key nodes such as the installation of prefabricated components to ensure construction compliance with regulations.
3. Quality Traceability System: From raw material testing to factory certificates, all information is integrated into the government regulatory system, enabling full lifecycle traceability of prefabricated components. Once problematic components are identified, their sources can be quickly located and held accountable.
4. Mandatory Green Building Certification: Projects must obtain green building evaluation labels within one year of completion and submit testing reports before acceptance, promoting the integration of prefabricated buildings with green buildings.

III. Policy Incentives and Cost Optimization
The government reduces enterprise costs through floor area ratio incentives: After developers sign a 'Commitment Letter' and submit a technical plan, they can receive an incentive approval opinion letter within as fast as five working days. This 'lenient entry, strict exit' mechanism not only encourages enterprises to adopt prefabricated technology but also ensures quality compliance through subsequent supervision, achieving a balance between efficiency and safety.

IV. Typical Application Case
The police station office building in Huadu District, Guangzhou, was constructed using fully prefabricated methods. All components were prefabricated in a smart factory and assembled on-site. From the hoisting of the first module to delivery, it took less than a month, significantly shortening the construction period while reducing on-site wet operations and construction waste, demonstrating the efficient and environmentally friendly advantages of prefabricated buildings.
