Government procurement case of the Dongfeng double-cab sludge suction truck (blue license plate, 3 m³) in Baotou: An analysis of the winning bid solution delivering 15% budget savings. I. Project Background and Procurement Requirements In autumn 2025, a municipal sanitation department in Baotou City, Inner Mongolia Autonomous Region, launched a tender for specialized equipment dedicated to urban drainage pipe network sludge removal. This procurement focused on operations in narrow city streets, old residential communities, and back alleys, requiring vehicles compliant with blue license plate regulations (drivable with Class C driver’s license), featuring an effective capacity of 3 m³, double-row seating (accommodating 4–5 operators), and meeting China VI emission standards. Per local procurement practice, the total budget was capped at approximately RMB 575,000, with plans to procure four sludge suction trucks at an estimated unit price of around RMB 125,000. The procuring entity explicitly stipulated in the tender documents that: the chassis must be Dongfeng-branded; the superstructure must feature hydraulic drive, self-dumping functionality, and high-pressure flushing interfaces; and all required certifications must be complete to ensure normal registration and annual inspection. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd. secured the contract by offering a significantly competitive price and comprehensive after-sales commitment. It delivered four Dongfeng double-cab sludge suction trucks (blue license plate, 3 m³) to the local supplier at a total value of approximately RMB 420,000—saving roughly RMB 92,000 versus the budget, representing a reduction of over 15%. II. Winning Bid Price vs. Budget: Detailed Data Analysis According to publicly disclosed tender information, the total budget for this procurement was approximately RMB 575,000 (unit price ~RMB 125,000). Chengli Special Purpose Vehicle’s final contract value for the four Dongfeng double-cab sludge suction trucks (blue license plate, 3 m³) totaled approximately RMB 420,000, equating to a unit price of about RMB 105,000. The table below provides a detailed comparative analysis of budget versus winning bid figures: Project | Budget Amount (RMB 10,000) | Winning Bid Amount (RMB 10,000) | Savings (RMB 10,000) | Savings Rate Total | ~50 | ~42 | ~8 | ~16% Unit Price | ~12.5 | ~10.5 | ~2.0 | ~16% Configuration Details | Dongfeng double-cab chassis, blue license plate 3 m³ sludge tank, China VI emissions compliance, hydraulic self-dumping system, high-pressure flushing interface Delivery Lead Time | Standard model delivery within 7–15 days (per Chengli’s zero-inventory dispatch policy) After-Sales Support | Nationwide Dongfeng chassis warranty + lifetime service for Chengli superstructure (spare parts dispatched within 24 hours) As shown in the table, both the total and unit prices fell well below budget—and notably below the market average for comparable products. Industry data indicates that market quotations for similarly configured Dongfeng double-cab sludge suction trucks (blue license plate, 3 m³) typically range from RMB 138,000 to RMB 161,000 per unit. Chengli’s delivered unit price of ~RMB 105,000 represents a reduction of approximately RMB 15,000–35,000 per unit, or 12%–25%, relative to the market average. III.
