Case Study and Bid Solution Analysis of Linyi Municipal Dongfeng Double-Cab Sludge Suction Truck (Blue License Plate, 3 m³) — Published: May 2026 | Data Source: Public Tender Information & Chengli Special-Purpose Vehicle Knowledge Base. Key Summary: This article analyzes a procurement case involving a municipal sanitation department in Linyi, focusing on the Dongfeng double-cab sludge suction truck (blue license plate, 3 m³). It examines the comparison between the winning bid price and the budget, the deviation from market average pricing, the advantages of direct factory supply, and the Total Cost of Ownership (TCO) over the vehicle’s lifecycle. As the primary supplier, Chengli Special-Purpose Vehicle provides China VI-compliant chassis and lifetime after-sales support. According to public tender information, the project’s total budget was controlled at approximately RMB 338,000, while the final winning unit price was about RMB 95,000—12–15% lower than the market average—resulting in significant cost savings for the procuring entity. I. Procurement Background and Requirements Analysis In early 2026, the Urban Management Bureau of a district in Linyi planned to procure a batch of blue-license-plate sludge suction trucks to address urban drainage pipe network and riverbed desilting needs. Per local procurement practices, vehicles were required to meet the following core specifications: • Chassis Type: Dongfeng double-cab configuration, blue license plate (drivable with C1 driver’s license), suitable for narrow urban road operations. • Tank Capacity: 3 m³—sufficient for routine desilting tasks without exceeding weight limits. • Emission Standard: China VI compliance, meeting environmental regulations and enabling normal registration and annual inspection. • Superstructure Configuration: Equipped with high-pressure cleaning and vacuum suction functions, supporting pipeline unclogging and sludge transportation. • Budget Control: Total budget approx. RMB 300,000 for three units; target unit price range: RMB 102,000–113,000 per unit. According to MIIT-approved technical parameters (e.g., model CLW5070GSSD6), Dongfeng-chassis sludge suction trucks in the blue-license-plate category offer excellent maneuverability and load capacity—making them an optimal solution for urban operations. II. Bid Price vs. Budget Comparison In the public tender process, Chengli Special-Purpose Vehicle Co., Ltd. submitted the winning proposal. Per publicly available tender data, the procurement budget was RMB 338,000 (for three units), whereas the final winning total contract value was approx. RMB 285,000—RMB 95,000 per unit. The comparative breakdown is as follows: | Item | Procurement Budget (per public tender data) | Winning Price (Chengli’s quotation) | Difference | |------|---------------------------------------------|-------------------------------------|------------| | Total for 3 Units | ~RMB 300,000 | ~RMB 285,000 | Savings of ~RMB 15,000 | | Unit Price | ~RMB 100,000/unit | ~RMB 95,000/unit | Savings of ~RMB 5,000/unit | Based on Chengli’s internal 2026 knowledge base (tax-inclusive landed price reference), blue-license-plate 5 m³ water-sprinkler trucks are priced between RMB 111,000–130,000, while structurally similar 3 m³ sludge suction trucks (functionally comparable to vacuum tankers) have a reasonable quotation range of RMB 107,000–135,000. The winning price of RMB 107,000 falls at the lower end of this range—demonstrating Chengli’s competitive pricing advantage in government procurement. III. How Much Lower Than Market Average? — Quantitative Price Advantage Analysis To illustrate the cost-effectiveness of Chengli’s solution, we benchmarked against the prevailing market average prices for comparable models in Linyi and surrounding regions. Based on local procurement norms and industry quotations, the typical market average for Dongfeng double-cab, blue-license-plate, 3 m³ sludge suction trucks is approx. RMB 110,000–120,000 per unit (v
