I. Project Background: 'Starting from Scratch' — First-Time Procurement by a New Entity. Due to a sharp increase in industrial and domestic sewage treatment volumes within its jurisdiction, the Urban Management Bureau of a district in Qujing City, Yunnan Province, recently established a new municipal maintenance team and urgently needed to procure a batch of heavy-duty sludge dump trucks for transporting dewatered sludge from wastewater treatment plants. The agency had no prior experience in purchasing special-purpose vehicles and lacked clear understanding of vehicle models, chassis options, superstructure configurations, or budgeting. Per local procurement practices, the budget was capped at approximately RMB 501,000 per unit, with four units planned for purchase—totaling a budget of roughly RMB 2.006 million. Key vehicle requirements included: Sinotruk-branded chassis; cargo body capacity of 24 m³; and compliance with China VI emission standards to ensure normal registration and annual inspection in Qujing and surrounding areas. II. Vehicle Selection Process: From Zero to Finalized Specifications 1. Requirements Research and Preliminary Parameter Definition After issuing a pre-procurement notice via the government procurement platform, Zhang Yue, Sales Manager of Chengli Special Purpose Vehicle Co., Ltd. (located in Chengli Automobile Industrial Park, Economic Development Zone, Suizhou City, Hubei Province; Tel: ), proactively contacted the agency and provided free vehicle selection consultation. Based on actual operating conditions—including sludge moisture content (~80%) and density (~1.2 tons/m³)—the Chengli team recommended a Sinotruk chassis equipped with a hydraulic tipping superstructure and standard anti-corrosion/anti-seepage interior lining. Referencing technical parameters of similar Chengli models (e.g., CLW5250ZLJ sludge dump truck) listed in the official vehicle announcement database, the final technical specifications were confirmed as follows: overall vehicle dimensions approx. 10 m × 2.5 m × 3.3 m; internal cargo body dimensions 7.2 m × 2.3 m × 1.5 m; capacity 24 m³; rated payload ~12 tons; engine power 220 hp; China VI emission compliance. 2. Supplier Screening and Quotation Comparison The agency conducted an open tender and received responses from four suppliers. As a direct manufacturer, Chengli submitted a comprehensive technical proposal and quotation. According to publicly disclosed tender information, Chengli’s quotation was: RMB ~481,000 per unit, totaling RMB 1.728 million—below the budget ceiling. The other three quotations were RMB 499,000, RMB 455,000, and RMB 461,000 per unit, respectively. Chengli’s pricing advantage stemmed from factory-direct sales eliminating intermediaries—yielding savings of RMB 8,000–15,000 per unit compared to 4S-channel offerings with identical configurations.
