Government Procurement Case and Bid-Winning Solution Analysis for the New Dongfeng Sewage Treatment Truck in Suzhou Against the backdrop of growing municipal environmental protection priorities, sewage treatment trucks—critical equipment for emergency maintenance of urban drainage systems and remediation of black-and-odor water bodies—are seeing steadily increasing procurement demand. In 2024, the Urban Management Bureau of a district in Suzhou adopted a framework agreement procurement model to centrally procure a batch of new Dongfeng sewage treatment trucks. Based on publicly available tender information and Chengli Special Automobile’s practical delivery experience, this article analyzes the procurement process, eligibility criteria, order-triggering mechanism, and compares mainstream vehicle solutions—providing reference guidance for municipal sanitation authorities. I. Framework Procurement Background: From Single-Project Procurement to Integrated Management Traditional government procurement typically relies on single-project tenders, which are time-consuming and involve significant repetitive work. To improve efficiency, the Urban Management Bureau of this Suzhou district began implementing the framework agreement procurement model in 2023. The budget for this sewage treatment truck procurement project was capped at approximately RMB 3.96 million, with plans to acquire six units at an estimated unit price of around RMB 580,000; the service period is two years (per publicly disclosed tender information). Procurement scope includes vehicle supply, superstructure modification, after-sales training, and spare parts provision. The core advantages of framework agreement procurement are: one-time tendering, batch ordering, and demand-driven delivery—reducing repeated tendering costs while ensuring consistency in vehicle specifications. This procurement explicitly required vehicles to be built on the latest Dongfeng National VI chassis, with superstructures capable of sewage suction, solid-liquid separation, and automatic discharge; emissions compliance must meet National VI standards. II. Supplier Shortlisting Process: Dual Screening by Qualifications and Technical Parameters The shortlisting process for framework agreement procurement consists of two stages: prequalification review and technical proposal evaluation. 2.1 Prequalification Review Suppliers must satisfy the following basic requirements: - Possess independent legal person status, with business scope on their business license covering special-purpose vehicle manufacturing or sales; - Provide evidence of similar projects completed within the past three years (e.g., supply cases to municipal sanitation authorities—referencing Chengli’s experience serving over 500 such entities); - Hold official Ministry of Industry and Information Technology (MIIT) catalog approval for the corresponding vehicle model (e.g., Chengli CLW5070GSSD6); - Submit a formal after-sales service commitment letter (including nationwide chassis warranty coverage and lifetime superstructure service). 2.2 Technical Proposal Evaluation An evaluation panel scores suppliers’ technical documentation, focusing on: - Chassis configuration: Latest Dongfeng National VI engine, transmission, tires, etc.; - Superstructure performance: Sewage treatment capacity (e.g., hourly throughput), tank material (stainless steel or corrosion-resistant carbon steel), suction depth, etc.; - Regulatory compliance: Full compliance with national registration, annual inspection, and commercial operation requirements; - Warranty & after-sales support: Original-equipment manufacturer (OEM) chassis warranty, lifetime superstructure service, and 24-hour direct spare parts dispatch. Chengli Special Automobile successfully passed the shortlisting evaluation—leveraging its comprehensive MIIT catalog coverage, stable Dongfeng chassis supply chain, and mature sewage treatment vehicle design—and became one of the designated fra
