Analyzing the critical role of Technical Query Lists (TQL) in delivering high-performance architectural solutions for international developers.
Introduction to UHPC Technical Alignment
In the landscape of modern architectural engineering, Ultra-High Performance Concrete (UHPC) has redefined the boundaries of facade design. However, the complexity of this material demands more than just manufacturing expertise; it requires a rigorous alignment between design intent and industrial execution. This is particularly vital in international projects where regulatory standards and logistical constraints vary across borders.
Technical Requirement Clarification and Confirmation (TQL) serves as the bridge between a conceptual blueprint and a structural reality. By systematically identifying discrepancies and technical gaps, project teams can mitigate risks, control costs, and ensure that the final aesthetic matches the architect's vision. The following case study examines how these principles were applied to a landmark project in Russia.

Y Project: Technical Requirement Clarification & Confirmation List (TQL)
1. Quantity & Specification Clarification
Column Quantity Discrepancy: The client’s overall summary requested 1,117 units, but the height-specific breakdown (3.1m / 3.74m / 5.15m) totals 1,057 units. Please verify whether the missing 60 units correspond to other specifications or are intended as spare parts.
Pixel Elements Missing: The current technical package lacks detailed 3D node diagrams, individual dimensions, and total quantity for these decorative blocks. Without this information, mold calculation and pricing cannot be completed.
Interfloor Belt Segmentation: For 2,600 linear meters of beams, what is the preferred segment length? Do you accept the standard 3–4 meter segments to match 40'HC container transportation?
2. Core Process & Finish
Seamless 5.15m Columns: Please confirm whether the columns must be cast as a single piece without horizontal joints. This directly determines the number of our 5.5-meter ultra-large precision steel molds required.
Aggregate Texture: Confirm whether the large aggregate (Terrazzo-like) shown in the sample is full-body or only applied as a surface finish via sandblasting/polishing.
Surface Defect Standards: The “No Pits” requirement for UHPC products will be addressed with high-frequency vibration to reduce air voids. However, achieving complete “zero-pit” finish requires additional manual refinement, which adds cost. Please confirm the acceptable tolerance for inspection.
3. Fire Safety & Certification Requirements
K0/G1 Certification Responsibility: We will provide UHPC materials capable of meeting K0/G1 standards. However, should the official Russian Fire Safety Certificate be processed by us in China, or handled by your team through on-site testing in Russia, with associated costs borne locally?
Sample Shipment Quantity: Large-scale combustion tests for K0-rated exterior walls typically require substantial sample quantities. Please specify the required test sample surface area and the shipping address.
4. Structural Nodes & Fixings
Backing Structure: Do the decorative columns require pre-installed internal steel reinforcement or support frames?
Brackets & Fixings: Does the FOB quotation include all necessary stainless or galvanized steel brackets, back-bolts, and other fixing accessories for installation?
Wall Thickness: Based on UHPC strength above 120MPa, we initially recommend a wall thickness of 30–40mm. Please confirm whether this thickness meets your façade structural load requirements.
5. Commercial & Logistics Confirmation
Packaging: Due to the fragile nature of the 5.15m columns, we plan to use custom steel A-frame racks for vertical container loading. Please confirm whether your site has forklifts or overhead cranes capable of unloading such extra-long and heavy units.
Quotation Currency: Should the FOB quotation be issued in USD or CNY?
Strategic Importance of TQL in Global Projects
The Y Project case study demonstrates that technical clarification is not merely a procedural formality but a critical risk-management tool. In high-end UHPC applications, material efficiency is maximized through thin-wall designs and complex geometries. Without a documented TQL, discrepancies in quantity or structural nodes can lead to irreversible manufacturing errors.
Furthermore, the integration of logistical planning—such as the use of custom steel A-frames for 5.15m columns—ensures that the integrity of the material is preserved from the factory floor to the construction site. This holistic approach to quality management is what distinguishes industry leaders in the UHPC market.
Conclusion: Setting the Standard for Excellence
Achieving architectural excellence with Ultra-High Performance Concrete requires a combination of advanced material science and meticulous project management. By prioritizing technical requirement clarification (TQL), Zhuliyuan ensures that international projects, like the Y Group development in Russia, are executed with precision, safety, and aesthetic fidelity.
