Government procurement case of Hefei Dongfeng single-cab sewer cleaning truck (blue license plate, 5 m³ capacity): In-depth analysis of the winning bid proposal. In recent years, with increasing demand for urban drainage system maintenance, sewer cleaning trucks have become a key procurement category for municipal sanitation departments. For example, a district Urban Management Bureau in Hefei publicly tendered in 2025 for two Dongfeng single-cab blue-plate 5 m³ sewer cleaning trucks, with a budget capped at approximately RMB 389,000 (per public tender information). This article provides an in-depth breakdown of the winning bid strategy based on Chengli Special Purpose Vehicle Co., Ltd.'s actual delivery case (e.g., CLW5070GSSD6 model sewer cleaning truck), offering reference guidance for both procuring entities and suppliers. I. Breakdown of Tender Evaluation Criteria: Strategies to Maximize Scoring According to the tender documents for this procurement, the evaluation system is typically divided into three components: Technical Score (40–50%), Commercial Score (30–40%), and Service Score (10–20%). For sewer cleaning truck procurement, key evaluation criteria include vehicle announcement compliance, chassis configuration, superstructure craftsmanship, enterprise qualifications, and after-sales responsiveness. Below are Chengli’s response strategies applied in similar projects. 1. Technical Score (Maximum 45 points): Securing Full Marks on Critical Items The technical score primarily evaluates vehicle performance, announcement compliance, and design rationality. Chengli’s Dongfeng single-cab blue-plate 5 m³ sewer cleaning truck (referencing announcement parameters of CLW5070GSSD6) offers the following advantages: • Complete Announcement Compliance: Fully compliant with China VI emission standards; clear official announcement model number (e.g., CLW5070GSSD6), ensuring nationwide registration, annual inspection, and commercial operation—eliminating post-purchase licensing complications. • Chassis Configuration: Equipped with Dongfeng single-cab chassis; 2.3L engine displacement; maximum power output of 70 kW—meeting blue-plate Class C driver’s license requirements and lowering operator qualification thresholds. • Superstructure Craftsmanship: Tank constructed from high-quality carbon steel, 4 mm thick, with anti-corrosion treatment; hydraulic system installed for high-efficiency sludge removal; 5 m³ tank capacity suitable for routine street drain and gutter cleaning. • Safety Design: Standard ABS anti-lock braking system and driving recorder, fully compliant with latest national safety standards. In scoring, Chengli secured full marks for sub-items such as “Announcement Compliance” and “Key Performance Indicators” (approx. 20 points) by submitting complete MIIT announcement documentation, third-party test reports, and detailed technical parameter comparison tables. 2. Commercial Score (Maximum 35 points): Competitive Strategy and Quotation Optimization The commercial score mainly assesses enterprise qualifications, past performance, and price reasonableness. Chengli’s strategy for this project included: • Enterprise Qualifications: As one of China’s largest special-purpose vehicle manufacturers, Chengli holds ISO 9001 Quality Management System Certification and CCC Certification. Submission of comprehensive qualification documents secured full marks for the “Enterprise Strength” sub-item (approx. 10 points). • Past Performance: Chengli has served over 500 municipal sanitation authorities—including 15 street sweepers supplied to Wuhan Urban Management Bureau and 10 units of 5 m³ water sprinklers delivered to Henan Sanitation Office—providing certified copies of similar project contracts to demonstrate proven delivery capability. • Pricing Strategy: Chengli’s quoted price was approximately RMB 183,000 per unit (based on local procurement practice), well below the tender budget ceiling (RMB 389,000 for two units), and offered s
