Yuanda Prefabricated Concrete Houses

Yuanda prefabricated concrete houses, namely the prefabricated buildings of Yuanda Zhugong, are houses constructed through industrialized production methods, characterized by high efficiency, high quality, and controllability.

I. Corporate Background and Product System As a leading enterprise in China's prefabricated building industry, Yuanda Zhugong has over 20 years of development history. It has established an 8-generation prefabricated building product system, completed more than 1,000 project practices, and formed a strategic factory layout covering the entire country. Its core advantage lies in not altering the architectural form, structure, general contracting model, or cost, but rather reconstructing the construction process through industrialized production methods to achieve dual improvements in efficiency and quality.

II. Technological Innovation and Laboratory Support Yuanda Zhugong has set up six key laboratories to drive technological breakthroughs:

1. Standardization Laboratory: Collaborates with real estate enterprises to establish a standardized technical support system, achieving standardization and digitization at the product end.
2. Modularization Laboratory: Introduces manufacturing design concepts to build a universal module library, simplifying the design process.
3. Digitalization Laboratory: Utilizes big data to develop digital modeling tools, optimizing building information management.
4. Process Laboratory: Establishes a standard module process database to support digital manufacturing and construction, providing data assurance for production and construction.
5. Graphics Laboratory: Researches architectural visualization expression, achieving separation and interchangeability of graphics and data, enhancing module selection efficiency.
6. Blockchain Laboratory: Applies blockchain technology to manage smart contracts, covering approval, procurement, supervision, and other links, enhancing transaction transparency and security.

III. Core Advantages and Data Support This system possesses four main characteristics:

• Controllable Construction Period: Industrialized production shortens the on-site construction cycle.
• Controllable Cost: Reduces material and labor waste through standardization.
• Controllable Quality: Factory-prefabricated components have higher precision than on-site pouring, reducing quality fluctuations.
• Improved Efficiency: Reduces formwork usage by ≥75%, decreases carpenter demand by 70%, and reduces steel bar workers and mason demand by 40% and 30%, respectively.

IV. Standardization Construction and Industry Contributions As of April 2019, Yuanda Zhugong has participated in formulating 3 national standards, 1 industry standard, and 27 provincial standards, compiled 3 published atlases and 5 professional monographs, providing important references for the standardized development of the industry.

V. Application in Rural Housing Market The "Yuanda Meizhai" project launched for the rural market adopts fully prefabricated technology to build high-end industrialized villas. For example, Sika provides joint waterproofing solutions for this project. Its SikaHyflex®-250 PC sealant offers superb weather resistance and 50% displacement compensation capability, combined with SikaPrimer®-3N primer to achieve excellent adhesion to concrete, ensuring long-term waterproofing performance of the building.
