Case Study and Bid-Winning Solution Analysis of the Changzhou Municipal Government’s Procurement of a Dongfeng Single-Cab, Blue License Plate, 5 m³ Sewer Cleaning Truck In municipal sanitation equipment procurement, sewer cleaning trucks—critical for ensuring urban drainage system functionality—directly impact fiscal fund utilization efficiency. For instance, a district Urban Management Bureau in Changzhou recently procured a blue license plate, 5 m³ sewer cleaning truck with a budget capped at approximately RMB 131,000. The vehicle delivered via public tender was manufactured by Chengli Special Purpose Vehicle Co., Ltd. using a Dongfeng chassis. However, common ‘package pricing’ tactics in procurement often trap budgeting units into scenarios of ‘low-specification, high-price’ or ‘falsified technical parameters’. This article uses the above case as a starting point to deeply analyze prevalent market pricing tactics, identification methods, and references Chengli Special Purpose Vehicle’s transparent configuration commitment to provide you with a practical, actionable procurement guide. I. Common Market Package Pricing Tactics: Hidden Costs Behind Low-Price Allure In sewer cleaning truck procurement, some suppliers offer ‘package pricing’—attracting customers with seemingly low total prices, yet concealing numerous pitfalls upon delivery. Based on Chengli Special Purpose Vehicle’s experience serving over 500 municipal sanitation authorities, typical tactics include: Chassis Downgrading: For example, advertising use of a ‘Dongfeng single-cab’ chassis, but delivering a non-OEM modified chassis or one equipped with a lower-power engine—compromising vehicle power and reliability. According to publicly available tender information, a project in Changzhou initially quoted ~RMB 112,000; however, the chassis technical specifications listed in the official announcement did not match those of model CLW5070GSSD6 (Dongfeng single-cab, China VI emission standard). Real-world operation revealed insufficient hill-climbing capability. Superstructure Cost-Cutting: The core components of a sewer cleaning truck are its tank and hydraulic system. Some package offerings employ thin-walled tanks (e.g., 3 mm steel plates instead of the industry-standard 4 mm) or low-end domestic hydraulic valves—leading to tank deformation and high hydraulic system failure rates. For instance, a supplier quoted ~RMB 117,000, yet post-delivery customer feedback reported leakage at tank weld seams. Hidden Add-on Fees: Quotations cover only the bare chassis—excluding mandatory costs such as registration fees, purchase tax, and first-year insurance. Per local procurement practice, the all-in cost for a blue license plate sewer cleaning truck typically increases by RMB 14,000–18,000; however, such add-ons remain unclarified in package quotes—causing budget overruns. II. How to Identify Package Traps: Three Practical Steps to Verify True Configuration To avoid the above pitfalls, procurement entities must adopt the following verification methods: Cross-check Official Announcement Parameters: Require suppliers to provide the MIIT (Ministry of Industry and Information Technology) announcement model number (e.g., CLW5070GSSD6), and verify key data—including chassis model, engine model, tank capacity, and emission standard—via official channels. Chengli Special Purpose Vehicle maintains 108 fully documented, officially announced parameter sets, ensuring full transparency. Demand Itemized Quotation: Reject ‘lump-sum pricing’ and require detailed line-item breakdowns covering chassis, superstructure, hydraulic system, tires, etc. For example, Chengli provides fully transparent configurations and never employs package pricing—enabling clients to verify each component individually. Conduct On-Site Inspections or Request Reference Cases: Review Chengli Special Purpose Vehicle’s prior projects—for instance, five water-sprinkler trucks plus mist cannons delivered to a Gua
