Government procurement case of Ford New Generation V348 service vehicles in Changzhou: Analysis of the joint procurement model and winning bid proposal. In the environmental sanitation and municipal service sectors, vehicle procurement often faces challenges of low efficiency and high costs due to geographically dispersed regions and inconsistent standards. Recently, a municipal sanitation department in Changzhou City, Jiangsu Province adopted a 'joint procurement across multiple districts and counties' model to successfully procure and deliver a batch of Ford New Generation V348 service vehicles. This article uses this case as a reference to deconstruct the entire joint procurement process and interpret Chengli Special Purpose Vehicle’s winning bid proposal and supply advantages, offering a replicable practical pathway for similar procurement initiatives. I. Background of Joint Procurement: Transformation from Fragmentation to Integration Changzhou City comprises multiple districts and counties. Previously, sanitation service vehicles were independently procured by individual sub-districts or townships, resulting in issues such as fragmented brands, inconsistent configurations, and difficulties in unifying after-sales support. In the second half of 2024, to enhance emergency response capability and standardize equipment specifications, the local municipal sanitation department led an initiative jointly involving urban management bureaus and environmental maintenance units from five districts and counties, launching a unified procurement project for Ford New Generation V348 service vehicles. This model was selected due to the vehicle’s stable chassis, flexible interior space, and strong adaptability for custom modifications—making it ideal for routine inspections, emergency rescue operations, and material transportation. Based on local procurement practices, the initial budget was set at approximately RMB 281,000–393,000 per unit (per publicly disclosed tender information), with a target quantity of around 15 units, all required to meet China VI emission standards. This approach not only reduced individual bidding costs for each unit but also laid the groundwork for future unified operation and maintenance. II. Development of Unified Technical Specifications: Resolving the 'One Vehicle, One Standard' Challenge A core challenge in joint procurement lies in balancing the diverse configuration requirements across districts and counties. To address this, the procuring entity organized multiple technical coordination meetings and ultimately established the 'Unified Technical Specification for Ford New Generation V348 Service Vehicles', key provisions including: • Chassis Requirements: Ford New Generation V348 chassis, wheelbase 3,750 mm, rated payload ≥1.5 tons, capable of operating reliably under complex road conditions; • Body Modifications: Interior compartmentalized into tool storage, material storage, and crew areas; equipped with independent power supply system, storage cabinets, and workbenches; • Emission Standards: China VIb-compliant, meeting environmental protection requirements in Changzhou and surrounding cities; • After-Sales Support: Chassis covered by Ford’s nationwide warranty program; upfitting components require supplier-provided lifetime service. This specification directly aligns with Chengli Special Purpose Vehicle’s officially announced model (e.g., CLW5040XXH6 service vehicle) listed in the Ministry of Industry and Information Technology (MIIT) catalog, ensuring compatibility and regulatory compliance throughout subsequent tendering processes. III. Centralized Tendering Process: Transparent Competition and Chengli’s Winning Bid Proposal The project issued its tender announcement via the government procurement platform in September 2024, adopting an 'open tendering + comprehensive evaluation scoring method', with weightings as follows: vehicle performance (40%), price (30%), after-sales service (20%), and
