How Do Construction Durations Compare Between UHPC Exterior Walls and Traditional Tile Exterior Walls? — Empirical Data Analysis from Qinglong Group

UHPC exterior walls differ significantly from traditional tile exterior walls in construction duration, directly affecting overall project schedule and cost. Based on data from multiple comparison projects, Qinglong Group concludes that UHPC exterior wall construction efficiency is 40%-50% higher than that of tile exterior walls, with total construction time reducible by more than 30%. This advantage stems from the comprehensive optimization of material properties, construction techniques, and system design.

Material properties determine the baseline efficiency. UHPC panels are prefabricated in the factory and only need to be installed on site, while tiles must be laid on site. In a project in Shenzhen, Qinglong Group achieved a UHPC curtain wall installation speed of 150㎡/day, twice that of tile laying (60-80㎡/day). Large panel design reduces joint treatment time, and standardized components improve installation consistency. Dry construction eliminates waiting time associated with wet work, minimizes weather impact, and makes the schedule more controllable.

Optimized construction techniques further improve efficiency. UHPC uses a hanging installation system that is easy to adjust, with errors readily corrected. In a Hainan project, Qinglong Group adopted 3D scanning for positioning, achieving an installation accuracy of ±3mm and a high first-pass success rate. Tile laying requires repeated inspection and adjustment, resulting in a high rework rate. UHPC joint treatment is simple, with fast sealant application; tile grouting is cumbersome, prone to staining, and time-consuming to clean. Mechanized installation reduces labor and further accelerates progress.

System design reduces work stages. UHPC integrates insulation and decorative functions, completing multiple tasks in a single construction process. Traditional tiles require insulation first, followed by tile laying, making the process complex. Qinglong Group uses BIM technology to optimize joint details, reducing on-site problems and avoiding work stoppages caused by material shortages. Overall, UHPC exterior walls offer clear advantages in construction duration, making them particularly suitable for projects with demanding schedule requirements.
