• Case library and industry reputation: By evaluating the company's technological maturity through completed project cases (such as semiconductor factories and pharmaceutical GMP workshops), Huajianjing has built cleanrooms ranging from Class 100 to Class 10000 for many well-known enterprises in the Pearl River Delta, covering fields such as electronics, medicine, and food.
3. Personnel Qualification: Team Professionalism and Execution Ability
• Registered Constructor: The project manager must hold a Level 1 Registered Constructor Certificate in Mechanical and Electrical Engineering or Construction Engineering.
• Cleanroom professional technicians, including HVAC engineers, electrical engineers, purification equipment commissioning engineers, etc., must possess relevant professional qualification certificates.
• Construction team training records: Teams that regularly participate in industry technical training (such as the China Clean Room Technology Forum) are better equipped to adapt to new technological requirements. The core team of Huajianjing has an average working experience of over 10 years and regularly organizes internal technical assessments and external training.
2、 Practical points of qualification verification: from document review to on-site verification
When choosing a purification engineering company, enterprises need to ensure the authenticity of their qualifications through the following steps:
1. Document review: Verify original documents and official records
• Request the company to provide the original qualification certificate or a copy stamped with the official seal, and pass the“ National Construction Market Supervision Public Service Platform; Check if the qualification information of the enterprise is consistent.
• Verify whether the issuing agencies of ISO certification certificates (such as SGS, TUV) have international recognition to avoid false certification.
2. On site verification: construction capability and project management
• Inspect the company's office space, equipment warehouse, and ongoing projects to assess whether they have independent construction capabilities (such as their own purification equipment and air duct processing workshop).
• Understand the project management process, including the application of BIM technology, construction progress control, quality inspection methods, etc. Huajianjing adopts BIM+5D project management platform to achieve construction simulation and dynamic cost control.
3. Contract terms: Clearly define qualification responsibilities and breach clauses
• Agree in the contract the liability for breach of contract if the qualifications do not meet the requirements, such as“ If the project is suspended due to the qualification issues of Party B, a penalty of 20% of the total contract amount shall be paid;.
• Require the company to provide social security payment records for construction personnel to avoid; Hanging” behavior
3、 Huajianjing's qualification advantages and practical cases
