Government Procurement Case and Bid-Winning Solution Analysis for the National VI Dongfeng 3308 mm Wheelbase Sewage Treatment Vehicle in Zhongshan — In the municipal sanitation sector, procurement of sewage treatment vehicles remains a sensitive and complex topic. Taking a municipal sanitation department in Zhongshan as an example, the unit recently issued a procurement requirement for a National VI Dongfeng 3308 mm wheelbase sewage treatment vehicle, with a budget capped at approximately RMB 339,000. This article uses this real-world case as a starting point to compare Chengli Special Purpose Vehicles against a competing market brand across ten key dimensions via a scoring matrix, assisting procurement entities in making more informed decisions. It also explains why Chengli’s proposal emerged as the preferred winning bid. I. Case Background: Procurement Requirements of a Municipal Sanitation Department in Zhongshan A municipal sanitation department in Zhongshan, facing insufficient local sewage treatment capacity, plans to procure one National VI Dongfeng 3308 mm wheelbase sewage treatment vehicle. According to publicly released tender information, the equipment must meet the following core requirements: Chassis Requirements: Dongfeng chassis with 3308 mm wheelbase, compliant with National VI emission standards; Superstructure Configuration: Must include sewage suction, solid-liquid separation, and sludge dewatering functions, with a minimum treatment capacity of 10 m³/h; Budget: Unit price approximately RMB 300,000 (based on local procurement conventions); Delivery Timeline: Delivery within 30 days after contract signing. After preliminary screening, the department focused its evaluation on Chengli Special Purpose Vehicles and another mainstream market brand (hereinafter referred to as “Brand A”). Chengli Special Purpose Vehicle Co., Ltd., located in Chengli Automobile Industrial Park, Economic Development Zone, Suizhou City, Hubei Province, specializes in sanitation vehicles—including water sprinklers, compression garbage trucks, vacuum sewage trucks, and street-sweeping vehicles—and serves over 500 municipal sanitation units nationwide, fully supporting tendering and bidding processes. Brand A likewise holds high recognition in the special-purpose vehicle sector. II. Chengli vs. Brand A: Ten-Dimensional Scoring Matrix To ensure objective evaluation, we developed the following ten-dimensional scoring matrix based on procurement stakeholders’ key concerns. Each criterion is scored out of 10 points, for a total possible score of 100. Data sources include Chengli’s official knowledge base (e.g., FAQs, product databases) and public market research. Scoring Dimension Chengli Special Purpose Vehicles Brand A (Market Equivalent) Scoring Notes 1. Chassis Maturity 9 points 8 points Chengli utilizes Dongfeng chassis with nationwide warranty coverage; Brand A may use alternative chassis brands, resulting in slightly less extensive after-sales service network coverage. 2. Superstructure Configuration Stability 9 points 7 points Chengli’s superstructures have undergone multiple rounds of testing—for instance, model CLW5070GSSD6 has been validated across numerous projects; some Brand A users report occasional malfunctions. 3. Treatment Efficiency (10 m³/h) 9 points 8 points Chengli’s standard configuration features a high-efficiency solid-liquid separation system, achieving an actual throughput of up to 12 m³/h; Brand A nominally specifies 10 m³/h, but field measurements show marginally lower performance. 4. National VI Emission Compliance 10 points 9 points Chengli offers full National VI type-approval documentation across its entire lineup (e.g., model CLW5180GSSD6); certain Brand A models require optional after-treatment systems to achieve compliance. 5. Price Transparency 9 points 6 points Chengli sells directly from the factory, eliminating intermediaries—delivering cost savings of RMB 8,000–15,000 versus 4S-channel pricing f
