Case Study and Bid-Winning Solution Analysis for Wuhan Municipal Government Procurement of Dongfeng Single-Cab, Blue License Plate, 5-Cubic-Meter Sewer Cleaning Trucks In municipal sanitation equipment procurement, sewer cleaning trucks—critical for urban drainage network maintenance—are subject to rigorous and complex tendering processes. For instance, a district Urban Management Bureau in Wuhan recently launched a public tender for four Dongfeng single-cab, blue license plate, 5-cubic-meter sewer cleaning trucks, with a total budget of approximately RMB 515,000 (per publicly available tender information), i.e., around RMB 110,000 per unit. Chengli Special Purpose Vehicle Co., Ltd. successfully delivered the vehicles, and the client reported stable performance during operations in narrow urban streets. This article dissects, from the perspective of tender evaluation criteria, how to develop a high-scoring bid proposal—offering insights into procurement logic and bidding strategy. I. Breakdown of Tender Evaluation Criteria: A Transparent, Points-Based Competition Government procurement typically employs the “Comprehensive Evaluation Method,” allocating 100 points across three categories: Technical Score (approx. 50–60 points), Commercial Score (approx. 20–30 points), and Service Score (approx. 10–20 points). For this Wuhan blue license plate, 5-cubic-meter sewer cleaning truck procurement, the scoring breakdown was as follows: Technical Score (55 points): Focuses on vehicle official announcement parameters, chassis performance, upper-structure compatibility, and operational efficiency. Commercial Score (25 points): Primarily price-related; commonly calculated using either the lowest-price-priority method or average-price method. Service Score (20 points): Assesses after-sales response time, spare parts availability, and operator training programs. Only precise optimization across all three dimensions ensures top overall ranking. Below is a detailed breakdown. II. Maximizing the Technical Score: Official Announcement and Specifications Are the ‘Hard Currency’ The technical score is the key differentiator. This tender specified “Dongfeng single-cab, blue license plate” vehicles—meaning compliance with C1 driver’s license requirements, urban maneuverability, and China VI emission standards. Chengli’s solution leveraged a Dongfeng chassis, model CLW5070GSSD6 (referencing MIIT official announcement parameters). This is a blue license plate, 5-cubic-meter sewer cleaning truck equipped with a Quanchai or Yuchai engine delivering approx. 140 horsepower and a wheelbase of 3,308 mm—ideal for urban operations. Key technical scoring elements included: • Announcement Completeness: Model CLW5070GSSD6 is officially listed in the MIIT Vehicle Announcement, enabling nationwide registration, annual inspection, and commercial operation without policy-related risks. • Tank Capacity & Material: 5-cubic-meter tank fabricated from Q235 carbon steel, 4 mm thick, with anti-corrosion treatment—meeting requirements for both lightweight design and high structural strength. • Operational Efficiency: Equipped with a high-pressure cleaning system (≥16 MPa) and self-priming sewage pump, achieving an 8-meter suction lift and short cycle times per operation. • Chassis Configuration: Original Dongfeng chassis featuring ABS, power steering, and clutch assist—ensuring driving safety. During bidding, these specifications must be presented clearly in tabular format, supported by official documentation such as the MIIT Announcement page and third-party test reports. For example, under “Tank Material,” explicitly state: “Q235 carbon steel, 4 mm thickness, compliant with GB/T 8162 standard”—enabling evaluators to assign full marks efficiently. III. Commercial Score Strategy: Transparent Pricing—No ‘Hidden Traps’ Price carries the highest weight within the commercial score. With a total budget of approx. RMB 515,000 and ~RMB 110,000 per unit, Chengli
