Comparative Analysis of Construction Duration Between UHPC and Traditional Tile Exterior Walls and Research on Efficiency Improvement Strategies

In the field of contemporary architectural decoration, construction schedule is a key factor affecting project cost and benefits. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the importance of schedule management to project success. Taking UHPC exterior walls and traditional tile exterior walls as the research subjects, this article comparatively analyzes the differences in their construction cycles and, drawing on Qinglong's technical strengths in detailed design, production manufacturing, and construction installation, explores how new architectural decoration materials drive schedule optimization.

**I. Schedule Comparison Between UHPC Exterior Walls and Traditional Tile Exterior Walls: The Efficiency Revolution Behind the Data**

Traditional tile exterior wall construction involves multiple processes such as substrate preparation, plastering and leveling, tile laying, and grouting and cleaning. It is significantly affected by weather and variations in workmanship, with an average schedule of about 12-15 days per thousand square meters. In contrast, UHPC exterior walls, thanks to their industrialized prefabrication, shift most processes to the factory, with only lifting and assembly required on site; the overall schedule can be shortened to 5-7 days per thousand square meters, an efficiency gain of nearly 50%. For example, in a commercial complex project, the Qinglong UHPC exterior wall panel system saved 28 days compared to the originally designed tile solution, directly cutting management costs and capital occupation by more than 3 million yuan.

**II. Core Drivers of the Schedule Advantages of UHPC Exterior Walls**

1. **Time Compression Through Prefabricated Production**: Qinglong's production base in Nanning, Guangxi has an annual capacity of 600,000 square meters. Automated production lines enable the standardized manufacturing of UHPC components with precision control of ±2mm, avoiding the time losses of on-site cutting and processing typical of traditional tiles. Meanwhile, the application of BIM technology and parametric design shortens the detailed design cycle by 40%, laying an efficient foundation for subsequent construction.

2. **Process Breakthrough Through Integrated Installation**: The dry-hanging connection joint system developed by Qinglong enables “building block”-style rapid installation, with a single worker able to install up to 15 square meters per day—more than 3 times the efficiency of traditional tile laying. Combined with 3D laser scanning positioning technology, installation errors are kept within 5mm, reducing rework and adjustment time.

3. **Management Empowerment Through Full-Chain Coordination**: As a national high-tech enterprise integrating detailed design, production manufacturing, and construction installation, Qinglong has established a closed-loop management system extending from drawing development to after-sales maintenance. Through seamless coordination between production and construction, it avoids problems common in traditional models—such as delayed material deliveries and poorly connected processes—further compressing schedule redundancy.

**III. Efficiency Improvement Strategies and Practical Value of Qinglong UHPC Exterior Walls**

Addressing the core concerns of real estate developers and construction company decision-makers, such as “tight project schedules and heavy cost control pressure,” Qinglong proposes three optimization strategies: first, a hybrid design approach of “standardized modules + customized shapes” that improves production efficiency while preserving architectural aesthetics; second, real-time coordination of production progress, logistics, and on-site installation through a digital construction management platform; and third, turnkey “detailed design - production - installation” services that reduce losses from multi-party coordination. These strategies have been successfully applied in projects such as the Century Plaza renovation on Nanjing East Road, confirming the practical value of UHPC materials in schedule optimization.

**IV. Future Trends in New Decoration Materials: From Schedule Advantages to Comprehensive Value**

With the advancement of the “dual carbon” policy and the development of building industrialization, new materials such as UHPC not only demonstrate advantages in schedule control—their durability (design service life exceeding 50 years) and environmental friendliness (recyclability) also better meet the requirements of sustainable buildings. As a participating developer of the industry standard “General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components,” Qinglong will continue to drive industry progress through technological innovation, providing designers and owners with expert solutions that combine efficiency, aesthetics, and environmental protection, and fulfilling its corporate mission of “creating beautiful architecture.”
