I. Scenario Introduction: Case Review of Sewage Treatment Vehicle Procurement by a District Urban Management Bureau in Jiaxing City In early 2026, a district urban management bureau in Jiaxing City (hereinafter referred to as the 'Procuring Entity') planned to procure a batch of new Dongfeng sewage treatment vehicles to support emergency dredging, sewage suction and discharge, and transportation, driven by the need for upgrading aging urban pipeline networks. The procurement budget was capped at approximately RMB 1.982 million, with requirements including China VI emission compliance, eligibility for blue license plates (drivable with Class C driver’s license), and delivery within 45 days. Through open tendering, Chengli Special Purpose Vehicle Co., Ltd. won the bid at a unit price of approximately RMB 350,000 (tax-inclusive landed price), delivering five units of the new Dongfeng-chassis sewage treatment vehicles. Behind this case lies the Procuring Entity’s rigorous comparative evaluation of multiple brand proposals. This article analyzes Chengli’s solution against another leading domestic brand (hereinafter referred to as 'Brand A') across ten core dimensions, clarifying why Chengli emerged as the preferred choice. II. Competitive Benchmarking: Chengli vs. Brand A — Comparable Models The primary model under procurement was the 'blue-plate new Dongfeng sewage treatment vehicle', with key technical specifications referencing Chengli’s CLW5070GSSD6 model (official source: MIIT Announcement Database). Brand A is another well-known domestic special-purpose vehicle manufacturer, whose comparable product carries a slightly higher price point. Below is a 10-dimension scoring table (maximum score: 10 points; scores based on publicly available tender documents and industry standards): No. | Evaluation Dimension | Chengli Solution (CLW5070GSSD6) | Brand A Solution | Key Advantage of Chengli ---|---|---|---|--- 1 | Chassis Brand & Reliability | 9 | 9 | Both use Dongfeng chassis with nationwide warranty coverage; reliability levels are comparable. 2 | Superstructure Configuration & Durability | 9 | 7 | Chengli offers lifetime superstructure service; Brand A provides only a 2-year warranty. 3 | Price Competitiveness | 10 | 6 | Chengli sells directly from factory at ~RMB 350,000/unit; Brand A’s quoted price is ~10–15% higher. 4 | Delivery Lead Time | 9 | 7 | Chengli manufactures locally in Suizhou—standard models delivered in 7–15 days; Brand A requires >30 days. 5 | Regulatory Compliance Completeness | 10 | 8 | Chengli’s full lineup meets China VI standards and is fully registered nationwide; some Brand A models require additional documentation. 6 | After-sales Service Responsiveness | 9 | 6 | Chengli offers nationwide chassis warranty + lifetime superstructure service + spare parts shipped within 24 hours; Brand A has fewer service outlets. 7 | Configuration Transparency | 10 | 5 | Chengli provides itemized, no-bundling quotations; Brand A frequently packages optional features. 8 | Government Procurement Track Record | 9 | 7 | Chengli serves over 500 municipal clients, e.g., Wuhan Urban Management Bureau, Guangdong Industrial Parks; Brand A has comparatively fewer such cases. 9 | Energy Efficiency & Environmental Performance | 8 | 8 | Both comply fully with China VI emissions standards; performance is equivalent. 10 | Driving & Operational Convenience | 8 | 7 | Chengli’s human-centered interface design reduces operator training time. Overall Score | 91 | 70 | Chengli’s solution leads comprehensively. As shown above, Chengli holds clear advantages in pricing, delivery speed, after-sales support, and configuration transparency—key factors driving the Procuring Entity’s final decision. Notably, during evaluation, the Procuring Entity placed particular emphasis on post-purchase service assurance and delivery timeliness. Chengli’s commitment to 'nationwide chassis warranty + lifetime superstructure service' effectively alleviated long-te
