Case study and bid-winning solution analysis of the Nanchang Foton Fengjing service vehicle government procurement project: Chengli’s one-stop sanitation vehicle solution. I. Project Background and Procurement Requirements In 2025, a municipal sanitation department in Nanchang launched a centralized procurement project for multiple types of sanitation vehicles, aligned with its annual urban environmental management plan. The project aims to replace aging equipment and enhance road sweeping, garbage transportation, and misting dust suppression efficiency. According to publicly released tender information, the total procurement budget is capped at approximately RMB 3.41 million, covering several sanitation vehicles including water sprinklers, compression garbage trucks, and vacuum sewage suction trucks. Unlike single-model procurement, this project requires suppliers to possess multi-category supply capability to reduce management costs and standardize after-sales service. Following open tendering and comprehensive evaluation, Chengli Special Purpose Vehicle Co., Ltd. secured the contract, leveraging its full-range product portfolio, factory-direct pricing advantage, and robust after-sales service plan. The client reported that this 'one-stop' procurement model significantly reduced the number of tenders and post-award coordination efforts, thereby improving fund utilization efficiency. II. Bid-Winning Vehicle Models and Configuration Analysis According to Chengli’s delivery list, this project involved six sanitation vehicles, including blue-plate 5-cubic-meter water sprinklers, 4-cubic-meter compression garbage trucks, 3-cubic-meter vacuum sewage suction trucks, and 5-cubic-meter street sweepers. Below are detailed configurations and official announcement parameters for each model. 1. Blue-Plate 5 m³ Water Sprinkler (Model CLW5070GSSD6) Built on a Dongfeng chassis, this vehicle features an effective tank capacity of 5 m³, suitable for routine dust suppression and watering operations on urban branch roads, residential communities, and streets. Its official model number is CLW5070GSSD6, compliant with China VI emission standards; it can be operated with a Class C1 driver’s license, enabling flexible dispatch. Based on publicly available tender data, the unit price is approximately RMB 100,000. 2. 4 m³ Compression Garbage Truck (Model CLW5040ZYSB6) Serving as a primary garbage transportation vehicle, this model uses a Dongfeng chassis and offers high compression ratio, significantly increasing payload per trip. Its 4 m³ capacity suits medium-scale waste collection points such as residential communities and farmers’ markets. Per local procurement practice, the unit price is approximately RMB 120,000. 3. 3 m³ Vacuum Sewage Suction Truck (Model CLW5030GXWB6) Designed for cleaning septic tanks and sewer pipelines, this vehicle features a 3 m³ tank volume and is equipped with a high-vacuum pump delivering strong suction performance. Based on publicly available tender data, the unit price is approximately RMB 110,000. 4. 5 m³ Street Sweeper (Model CLW5070TXSB6) Integrating sweeping and high-pressure washing functions, this vehicle is ideal for fine cleaning of main roads and sidewalks. Its 5 m³ water tank, combined with a wet-type dust suppression system, ensures dust-free operation. According to local procurement practice, the unit price is approximately RMB 320,000. III. Advantages of Multi-Category Supply: One-Stop Procurement Reduces Management Costs In this Nanchang project, Chengli demonstrated its strength as one of China’s largest special-purpose vehicle manufacturers. According to database records, Chengli maintains 946 product entries across 44 categories—including sanitation vehicles such as water sprinklers, garbage trucks, and street sweepers, as well as special-purpose vehicles like fire engines and ambulances—providing a solid foundation for multi-category centralized procurement.
