2017 China Precast Concrete Industry Development Report
 
Source: Beijing Precast Concrete Institute
 
In 2017, the development of China's prefabricated building industry was a matter of great concern. Jiang Qinjian, president of CCPA and chairman of Beijing Precast Concrete Institute, made a detailed analysis on the development of the precast concrete industry in China. 
 
Investigation on the Development of Prefabricated Components Market in China
Along with the continuous deepen of standard preparation, technical training and other activities, a flood of enterprises and professionals are drawn to engage in prefabricated building industry. The construction of PC plants and the implementation of demonstration project have turned into the breakthrough for promoting prefabricated building in various places, which has drawn a bright blueprint for the unprecedentedly prosperous prefabricated building development, specially in Shanghai, Beijing, Shenzhen and so on. 
 
EPC Product Manufacturing Management Model
Relying on the comprehensive resources of the industry chain, some enterprises specialize in processing and supply of PC styling products and customized products. The premise is that PC market orders are sufficient or as a professional factory to achieve the overall target.
 
Typical Enterprises: China Construction, Baoye Group, SCG, Chengdu Construction, etc.
Professional Contract Management Model
Relying on the advantages of technology, management and brand, comprehensive supporting service for the design, production and installation of prefabricated components will be offered towards marketization and specialization.
 
Typical Enterprises: BYPCE, Yatai Group, Onestar, MGC, etc.
Serious Quality Problems of PC Products 
Except for some well-established prefabricated component enterprises, the overall quality level of prefabricated concrete component enterprises throughout the country is still relatively low, mainly due to the lack of experience in component production, shortage of technicians, and inadequate management systems, which has caused many factories to rely on contract completely substituting administration. Furthermore, the shortage of production quality management team and technical worker training seriously restricts the sustainable and sound development of precast concrete industry and prefabricated building.
PC Product Quality Management Measures
For above problems, the construction supervisors of first-tier cities such as Beijing, Shanghai, and Shenzhen have attached great importance to the quality supervision of prefabricated components, issuing quality management regulation for prefabricated component production and prefabricated construction projects to strengthen product inspections and component inspections for prefabricated component manufacturers. What they have done has achieved some results.
 
Study on Technical System of Prefabricated Building
PC Product Analysis of Concrete Structure Building Technology System
The cast-in-place concrete structure system is divided into four parts, namely entire cast-in-place, cast-in-place in main structure, horizontal structure superposition and prefabricated exterior wall panels. Their prefabricated rate is 0-25%. The system is mainly suitable for multistory and high-rise buildings. 
PC Product Analysis of Prefabricated Concrete Structure Technology System
The prefabricated rate of prefabricated concrete structure technology system is 25%-100%. The prefabricated concrete structure technology system includes horizontal members, vertical members and fully prefabricated. Apart from multiple and high-rise buildings, the system is also suitable for low-rise buildings.
PC Product Analysis of Steel Structure Construction Technology System
Compared with the former two systems, the prefabrication rate of the steel structure construction technology system is relatively high, ranging from 50% to 100%. The system covers horizontal structure superposition, prefabricated exterior wall panels, precast stair, precast balconies and light partition wall.
Precast Prestressed Long-span Members
The application of industrial long-span prefabricated prestressed members has been increasing year by year. At present, the application of double-T plates and prestressed hollow slabs in long-span concrete frame structures and steel structures has been a matter of great concern.
Precast Facade for Prefabricated Building Envelope Systems
The development of precast facade for prefabricated building envelope systems is the direction of future development. The precast facade is characterized by its integration of decoration, maintenance and heat preservation, which is a key component of prefabricated buildings. Many companies across the country are developing various forms of precast facade plate products.
Precast Component in Municipal Infrastructure
The development of municipal infrastructure prefabricated components is mainly reflected in prefabricated pipe corridors, prefabricated prestressed bridges, prefabricated segments, water supply and drainage pipelines, etc, with colossal market.
 
Study on Development Planning of Prefabricated Factory in Key Regions
Focusing on the development of large cities, the coordination relationship between prefabricated component market demand and prefabricated plant resource allocation will be studied; Prefabricated factories should be arranged in an industrial zone away from the core area of the big city. The product supply radius should be in the range of 50-150 km; Convenient transportation around the factory, raw material resources and energy supply are guaranteed; The capacity of the integrated PC plants should be designed according to 100,000 to 150,000 cubic meters, and the floor space should be controlled to 150-250 acres. The total investment of civil engineering equipment should be controlled at 1.2-200 million yuan; The production capacity of professional PC factories should be designed according to 30,000-80,000 cubic meters, covering an area of 60-120 mu. The total investment of civil engineering equipment should be controlled at 4,000-80 million yuan.

Conclusion
The prefabricated components have low standardization, less sort of components, low overall quality of production, and insufficient service supporting capacity, which seriously limits the sustainable and healthy development of fabricated buildings.
 
The technical system for assembling high-rise building with integral concrete structure is basically mature. The technical system of assembled multi-low-rise concrete structure and steel structure has not yet been formed, but the implementation effect is not ideal. It is necessary to ameliorate the project management mode and improve the construction quality management measures. 
 
For the large-scale design and construction enterprises, the prefabricated building development path can focus on the integrated engineering general contracting mode of R&D, design, production and construction.
 
In the process of integrated management, professional prefabrication companies should put emphasis on developing the processing supporting service capacity of prefabricated products, and develop the market by relying on quality and service.
 
Suggestions
The standardization and serialization of precast concrete components is the basis for the sustainable and sound development of prefabricated buildings. It is hoped that all enterprises and localities can develop new products according to their own characteristics, perfect the product application technology system of prefabricated components, and better serve the needs of high-quality and efficient industrial construction.
 
The development of prefabricated concrete and prefabricated construction industry requires extensive participation of the whole society and various industries. All parts of the country should attach great importance to the outstanding problems such as quality, efficiency, market and so on, and continue to sum up experience and draw lessons from the practice.
 
Through our concerted efforts, China is bound to usher in a new era of sustainable and healthy development of precast concrete and fabricated buildings.
