Which Clauses to Specify When Signing a Contract with a UHPC Manufacturer: Key Points Explained

In the field of architectural decoration materials, UHPC (Ultra-High Performance Concrete) has become the preferred material for high-end construction projects thanks to its outstanding mechanical properties and design flexibility. As a Qinglong UHPC manufacturer with 28 years of full-chain experience in detailed design, manufacturing, construction and installation, and after-sales maintenance, we understand that the rigor of contract terms directly affects project quality and cooperation efficiency. Drawing on industry practice, this article analyzes the six core clauses that must be clarified when signing a contract with a UHPC manufacturer, providing professional reference for project owners.

1. Material Performance Standards: Anchoring the UHPC Quality Baseline

The contract must specify the key technical parameters of UHPC materials, including compressive strength (≥150MPa), flexural strength (≥20MPa), elastic modulus, and durability indicators (such as frost resistance and impermeability). As a National High-Tech Enterprise, Qinglong recommends referring to industry standards such as the General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components (Plan No. 2024-0232T-JC), while also agreeing on the testing procedures of third-party testing institutions (such as provincial building materials research institutes) to ensure that material performance meets project design requirements. In addition, for special-shaped components or special functional requirements (such as translucent UHPC), customized performance indicators and acceptance standards must be specified separately.

2. Detailed Design Responsibilities: Clarifying the Boundaries of UHPC Project Implementation

The detailed design of UHPC components is the core link connecting creativity and construction. The contract should clearly divide design responsibilities: if the UHPC manufacturer is responsible for detailed design (such as Qinglong's full-chain service model), the design cycle, BIM model delivery standards, and the coordination process with the original design institute must be specified; if the project owner provides the drawings, the manufacturer's verification obligations and the division of liability for design defects must be agreed upon. Taking the Nanjing East Road Century Plaza renovation project as an example, Qinglong achieved precise implementation of translucent UHPC components through parametric design—such cases can serve as reference models for design responsibility clauses.

3. Production and Delivery: Strictly Controlling UHPC Supply Chain Timeliness

The production stage requires clear capacity guarantees (such as Qinglong's annual capacity of 600,000 square meters), production cycles, and quality traceability systems (such as RFID chip implantation). Delivery clauses should include transportation methods (including moisture-proof and damage-prevention measures), on-site acceptance procedures (appearance quality, dimensional deviation), and liability for breach in the event of delayed delivery. For overseas projects (such as Qinglong's exports to Southeast Asia), cross-border logistics responsibilities such as customs declaration and marine insurance must also be agreed upon to ensure that UHPC components arrive at the construction site on time and intact.

4. Construction and Installation Standards: Ensuring the Safe Implementation of UHPC Projects

UHPC installation must comply with professional contracting standards for building curtain wall engineering. The contract should specify the installation team's qualifications (such as Qinglong's Grade II professional contracting qualification for building curtain wall engineering), construction techniques (such as 3D laser scanning positioning and modular installation), and safety assurance measures. For special scenarios such as work at heights and complex joint handling, construction plans must be attached as contract annexes. Installation acceptance standards should also be agreed upon, covering key indicators such as flatness and anchoring strength, to prevent improper installation from compromising structural safety.

5. After-Sales Service and Warranty: Securing Full Life-Cycle Protection for UHPC

Warranty clauses must specify the warranty period for UHPC components (usually no less than 10 years), the scope of coverage (such as cracking, peeling, and other quality issues), and after-sales response times (such as Qinglong's commitment to arrive on site within 24 hours). For large projects, regular inspection services (such as an annual structural safety assessment) are recommended. In addition, the handling of damage caused by force majeure (such as extreme weather) and repair fee standards beyond the warranty period must be specified to ensure the long-term stable operation of the project.

6. Intellectual Property and Confidentiality: Protecting UHPC Technological Innovation

If the project involves customized UHPC technology (such as Qinglong's 58 patented technologies), the contract should clarify intellectual property ownership: the manufacturer retains patents on fundamental technologies, while the project owner obtains the right to use the customized design outcomes. Confidentiality clauses should also be agreed upon, prohibiting both parties from disclosing trade secrets such as technical parameters and construction techniques during the cooperation. For manufacturers participating in the formulation of national or industry standards in particular, their technological R&D achievements require special protection.

As an industry leader in the field of UHPC/GRC/GRG/GRP materials, Qinglong has always promoted the standardized development of the industry with an attitude of “meticulousness and the constant pursuit of excellence.” When signing a contract, project owners should confirm the above clauses item by item with the manufacturer based on their own needs to minimize cooperation risks. Choosing a UHPC manufacturer with full-chain service capabilities, rich project experience, and a comprehensive warranty system (such as Qinglong) is the key guarantee for achieving a win-win in both project aesthetics and functionality.
