Case Background: Framework Agreement Procurement Practice by a Municipal Sanitation Department in Xi'an In early 2025, a municipal sanitation department in Xi'an planned to procure a batch of Foton Fengjing service vehicles to meet requirements for urban road inspection, emergency repairs, and equipment transportation. These vehicles needed multifunctionality—capable of carrying maintenance tools and spare parts while adapting to both urban and suburban road conditions. Traditional single-bid tendering processes are cumbersome; considering anticipated multiple, small-batch procurement needs over the next two years, the department adopted a 'framework agreement procurement' model—selecting qualified suppliers via public tendering for inclusion in the framework, with subsequent orders placed on an as-needed basis. In accordance with local procurement conventions, the budget was controlled at approximately RMB 170,000–227,000 per vehicle, with a total budget of roughly RMB 3.402 million–4.536 million, to be executed over two years. Following qualification pre-screening, technical evaluation, and price comparison, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') successfully entered the framework, leveraging its comprehensive after-sales service network, full range of China VI-compliant models, and desert-adapted vehicle solutions. This article analyzes the case from five perspectives: background of framework procurement, supplier selection process, order-triggering mechanism, Chengli’s competitive advantages, and FAQs—providing reference for similar procurement initiatives. I. Framework Procurement Background: Why Choose the Framework Agreement Model? Xi’an is located in Northwest China, where certain areas experience high wind-sand levels and arid, low-rainfall climates—posing higher demands on vehicle dustproof sealing and air filtration systems. Traditional single-procurement methods require repeated tenders, resulting in long cycles and high costs. The framework agreement procurement model allows the procuring entity to first select multiple qualified suppliers, agreeing upon specifications, unit prices, and delivery terms in advance; subsequent orders are then placed directly based on actual needs—significantly improving efficiency. During demand research, the department identified specific requirements for the Foton Fengjing service vehicles: installation of dustproof sealing kits, high-capacity air filters, and underbody protection plates specially designed for desert environments. Additionally, vehicles were required to provide over 200 L of storage capacity for emergency tools. Accordingly, the tender documents explicitly stipulated that chassis must comply with China VI emission standards, and the upfitting section must incorporate dustproof design and air filtration system maintenance solutions. Chengli responded with a Foton Fengjing-based service vehicle solution and provided climate-specific optimization recommendations tailored to Xi’an’s environmental conditions. II. Supplier Selection Process: How Did Chengli Stand Out? This framework agreement procurement consisted of four phases: 1. Qualification Pre-screening: Suppliers were required to hold special-purpose vehicle manufacturing licenses, possess complete China VI type-approval models, and demonstrate relevant project experience over the past three years. Chengli passed smoothly, drawing upon its experience serving over 500 municipal sanitation units—including 15 street-sweeping vehicles supplied to Wuhan Urban Management Bureau and 10 five-cubic-meter water-sprinkling trucks delivered to Henan Provincial Sanitation Office. 2. Technical Evaluation: Emphasis was placed on vehicle adaptability to desert environments. Chengli’s submitted Foton Fengjing service vehicle solution featured reinforced sealing strips, dustproof steering knuckles, and dual-stage air filters (similar in design to model CLW5070GSSD6), extending standard mai
