Case Study and Bid Winning Solution Analysis: Dongfeng Single-Cab Blue-Plate 5-cubic-meter Sewer Cleaning Truck Procurement by Handan Municipal Government In urban drainage network maintenance, sewer cleaning trucks are core equipment for ensuring pipeline unobstruction and mitigating urban flooding risks. In 2024, a municipal sanitation department in Handan City planned to procure a batch of Dongfeng single-cab blue-plate 5-cubic-meter sewer cleaning trucks, with a budget capped at approximately RMB 340,000 (per publicly available tender information). After multiple rounds of technical evaluation and price comparison, Chengli Special Purpose Vehicle Co., Ltd. was selected as the winning supplier. This article analyzes the procurement decision logic and competitive advantages of the winning solution, based on real-world procurement scenarios, through a 10-dimensional comparative assessment between Chengli’s offering and a comparable model from another market brand. I. Procurement Background and Requirement Analysis The municipal sanitation department is responsible for maintaining the drainage networks across Handan City’s main urban area and surrounding districts. Its existing sewer cleaning equipment is outdated, and most units are yellow-plate vehicles—restricted by urban road traffic regulations—resulting in low operational efficiency. The procurement explicitly required: Dongfeng single-cab cab configuration; blue license plate (eligible for C-class driver’s license); effective tank capacity of 5 cubic meters; China VI emission standard compliance; and integrated high-pressure cleaning and vacuum suction functionality. Budgeting followed local procurement conventions, with unit cost controlled at approximately RMB 170,000 or less. As stated by the procurement manager: “We need a vehicle capable of accessing residential communities and operating on elevated expressways, while also featuring low daily maintenance costs.” After preliminary screening, two suppliers advanced to final evaluation: Chengli Special Purpose Vehicle (solution based on Dongfeng chassis, referencing model series CLW5070GSSD6) and Market Brand A (same chassis platform but differing superstructure configurations). A detailed comparison follows. II.
