Design qualification for gas stations

Architectural design qualifications and pressure pipeline design qualifications. Depending on the characteristics of the project, lightning protection design qualifications and civil air defense design qualifications may also be required in some cases. According to the Ministry of Construction’s “Standards for Classifying Engineering Design Qualifications” (Document No. Jianzuo 22), design qualifications in the hazardous chemicals industry are divided into only two categories: Class A and Class B. Among them, engineering design firms that carry out projects across provinces must hold Class A design qualifications; firms with Class B qualifications are not allowed to engage in such cross-provincial work. Within the scope of services covered by design qualification certificates, the hazardous chemicals industry is divided into two categories: petroleum and natural gas, and chemicals, petrochemicals, and pharmaceuticals. Those with expertise in either of these two areas are eligible to engage in the engineering design of hazardous chemicals. Both Class A and Class B engineering design certificates are issued by the Ministry of Construction.
