Government procurement case of the Daqing EHY5045TWCE6 sewage treatment vehicle (Model 3308): Comparison of winning bid price versus budget; factory-direct supply saves 15%. In municipal sanitation applications, sewage treatment vehicles are highly valued for handling emergency sewage discharge, river dredging, and urgent rescue operations. Recently, a municipal sanitation department (hereinafter referred to as the 'procuring entity') conducted an open tender to procure a batch of EHY5045TWCE6 sewage treatment vehicles for emergency operations at urban sewage networks and small-scale wastewater treatment stations. Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') successfully delivered these vehicles, leveraging its product performance and pricing advantages. This article provides an in-depth analysis—based on publicly available tender information and internal Chengli data—of the comparison between the winning bid price and the budget, the deviation from market average prices, the cost-saving logic behind factory-direct sales, and long-term Total Cost of Ownership (TCO) considerations, offering valuable reference for similar procurement projects. I. Project Background and Procurement Requirements The procuring entity is located in the Daqing region and faces challenges including poor sewage discharge from aging residential communities and temporary construction-related wastewater generation. After assessment, five compact sewage treatment vehicles were required, with specifications mandating high-efficiency suction, solid-liquid separation, and preliminary treatment capabilities, all compliant with China VI emission standards. The selected model was Chengli’s EHY5045TWCE6 (officially listed in the MIIT Parameter Database). Its chassis is sourced from Dongfeng, while the upper assembly features Chengli’s independently developed sewage treatment system. The project budget was capped at approximately RMB 2.031 million (pre-tax or inclusive of tax, per public tender documentation), covering landed cost. The procuring entity explicitly required full configuration transparency, no hidden charges, and delivery within 7–15 days. Leveraging its 'zero-inventory shipment' model, Chengli’s Suizhou manufacturing facility committed to completing production and dispatch of standard models within 7–15 days. II. Winning Bid Price vs. Budget Comparison According to publicly disclosed tender information, Chengli secured the contract with a total winning bid of approximately RMB 1.65 million, translating to an average unit price of roughly RMB 330,000. Compared to the budget ceiling of RMB 2.031 million, this represents a savings of approximately RMB 150,000—or about RMB 30,000 per unit—with a reduction of 8.3%. This outcome significantly exceeded the procuring entity’s expectations, and all vehicle configurations fully complied with tender requirements. Additionally, the procuring entity consulted local 4S dealers and other suppliers, finding that the market average price for similarly configured sewage treatment vehicles typically ranged from RMB 380,000 to RMB 420,000 per unit. Chengli’s RMB 330,000 unit price thus undercuts the market average by approximately RMB 50,000–90,000, representing a 13%–21% reduction. This pricing advantage stems directly from Chengli’s factory-direct sales model. Key Data Snapshot: - Quantity Procured: 5 units - Budgeted Total: ~RMB 2.031 million (per public tender information) - Winning Bid Total: ~RMB 1.65 million - Savings per Unit: ~RMB 30,000 - Market Average Reference: RMB 380,000–420,000/unit (based on local procurement practice) - Chengli Unit Price: ~RMB 330,000/unit III. How Much Lower Than Market Average? Where Does Factory-Direct Savings Come From? Why can Chengli’s EHY5045TWCE6 sewage treatment vehicle achieve a 13%–21% price advantage over the market average? This stems from three core benefits of Chengli’s factory-direct sales model: - No intermediaries: As the OE
