Government Procurement Case and Bid-Winning Solution Analysis of Foton Fengjing Service Vehicles in Changde In municipal sanitation vehicle procurement, service vehicles—critical for daily inspections, equipment transportation, and emergency response—directly impact operational efficiency through their model selection. Recently, a municipal sanitation department (hereinafter referred to as 'Changde District Urban Management Bureau') procured a batch of Foton Fengjing service vehicles via public tender. Chengli Special Purpose Vehicle Co., Ltd. (hereinafter 'Chengli') won the bid based on comprehensive tender specifications and localized after-sales support. This article uses this case as a starting point and, combined with Chengli’s product knowledge base, analyzes the model selection logic, cargo volume matching, and procurement cost of the Foton Fengjing service vehicle, offering reference for similar institutions. I. Case Background: Procurement Requirement Analysis by Changde District Urban Management Bureau According to publicly available tender information, the Changde District Urban Management Bureau plans to procure six Foton Fengjing service vehicles, primarily for urban road inspections, small equipment transportation, and emergency material delivery. The project budget is capped at approximately RMB 1.352 million, with requirements including China VI emission standards, multi-purpose interior space, and a highly reliable chassis. Chengli ultimately delivered six vehicles compliant with the tender specifications (reference model: CLW5040XJHD6), priced at approximately RMB 200,000 per unit, for a total contract value of around RMB 1.2 million (based on publicly disclosed tender data). The significance of this case lies in highlighting how the importance of 'cargo volume-based model selection' for service vehicles is often underestimated. Unlike water-sprinkling or garbage trucks, service vehicles must simultaneously accommodate personnel and cargo; therefore, precise matching—based on daily workload, service radius, and application scenarios—is essential. II. Cargo Volume-Based Model Selection: How to Choose Among 3 m³ / 5 m³ / 8 m³ / 12 m³ Configurations? Although the Foton Fengjing service vehicle is not conventionally classified by 'cubic meter capacity', its cargo compartment volume can be categorized into approximate tiers of 3 m³, 5 m³, 8 m³, and 12 m³. Below is Chengli’s model selection logic derived from its internal knowledge base: • 3 m³ Class (Standard): Suitable for community- and street-level inspections within urban areas, with daily operational distance ≤ 50 km; accommodates 2–3 personnel plus light tools. In the Changde case, this configuration was used for routine inspections, with an estimated unit price of RMB 113,000–146,000. • 5 m³ Class (Medium-Large): Suitable for suburban or county-level operations, with daily operational distance of 50–100 km; capable of carrying small equipment (e.g., lawn mowers, pumps). Per Chengli’s CLW5040XJHD6 official specifications, the cargo compartment volume is approximately 5 m³, with an estimated unit price of RMB 203,000–248,000. • 8 m³ Class (Multi-Function): Suitable for emergency rescue or bulk material transport, with daily operational distance of 100–150 km; accommodates 4–6 personnel plus large tools. Estimated unit price: RMB 248,000–315,000. • 12 m³ Class (Heavy-Duty): Suitable for inter-regional dispatch or large-equipment transportation, with daily operational distance exceeding 150 km; estimated unit price: RMB 315,000–394,000. This specification was not adopted in the Changde case. III. Daily Operational Distance Calculation Formula and Corresponding Workload Matching Table To assist procurement units in making precise model selections, Chengli has synthesized feedback from over 500 municipal authorities to develop the following formula for calculating daily operational distance: Daily Operational Distance (km) = Service Radius (km) × 2 × Av
