I. Urgent Requirement: Emergency Procurement Triggered by Rainy-Season Support Mission In summer 2025, Liuzhou City in Guangxi Province experienced consecutive heavy rainfall, causing flooding on multiple low-lying urban roads. Prolonged submersion led to failures in several municipal facilities. A municipal sanitation and environmental department received an urgent directive from its superior authority to conduct comprehensive inspection and maintenance of drainage networks, road lighting, and emergency communication infrastructure within its jurisdiction—all within 15 days. Most existing vehicles were outdated models with poor sealing performance and severely rusted chassis, rendering them unreliable for stable operation under persistently high-humidity conditions. Internal assessment concluded an immediate need for a batch of service vehicles featuring high off-road capability, corrosion-resistant sealing, and rapid adaptability as mobile maintenance platforms. Based on local procurement practices, the budget was capped at approximately RMB 339,000–350,000 per unit. Requirements included compliance with China VI emission standards, waterproof and moisture-resistant capability, a spacious cargo compartment, capacity to accommodate diverse maintenance tools, and delivery within 20 days after contract signing. After multiple rounds of technical and commercial evaluation, the Ford Transit V362 chassis was selected as the base platform for modification, and Chengli Special Purpose Vehicle Co., Ltd. was commissioned to undertake full-vehicle modification and delivery. II. Expedited Tendering Process: From Requirement Confirmation to Contract Signing in Just 7 Days The municipal sanitation and environmental department issued an urgent quotation request notice in early July, specifying three core criteria: • Chassis Brand: Ford Transit V362 (2.0T diesel engine, China VI emissions compliant, front-wheel drive design for enhanced wet-surface handling) • Modification Requirements: Aluminum alloy shelving, anti-slip flooring, 220V power outlets, emergency lighting equipment, and waterproof storage cabinets inside the cargo compartment • Environmental Adaptability: Full-vehicle anti-corrosion coating; all sealing components must pass durability testing under hot-humid conditions (1,000 hours at 70°C / 95% RH without cracking) Upon receipt of the tender documents, Chengli Special Purpose Vehicle responded immediately. Leveraging deep familiarity with Liuzhou’s climatic conditions, Sales Manager Zhang Yue (Tel: +86 ) promptly assembled a dedicated technical team and submitted a complete modification proposal and quotation within 24 hours. The proposal specified the CLW5040XDYJ6 certified service vehicle model (Announcement No.: CLW5040XDYJ6; Chassis Model: JX5040XXYTD-L6), incorporating targeted enhancements for hot-humid environments: • Epoxy zinc-based anti-corrosion coating applied at chassis–body junctions, thickness ≥80 μm; salt spray resistance ≥500 hours • Door, side window, and inspection hatch seals upgraded to EPDM rubber, complemented by silicone gaskets—validated to withstand continuous heavy rain exposure • Entire electrical system equipped with waterproof connectors; wiring harnesses wrapped with moisture-resistant protective sheathing Following three rounds of technical clarification and commercial negotiation, the department announced Chengli Special Purpose Vehicle as the winning bidder on July 8—securing a procurement contract for five service vehicles at a unit price of approximately RMB 328,000 (per publicly disclosed tender data). The entire process—from requirement announcement to contract execution—took only seven days. III. Rapid Response: Production Scheduling to Shipment Completed in Just 14 Days Upon contract signing, Chengli Special Purpose Vehicle activated its 'Emergency Order Green Channel.' Chassis units were dispatched from Jiangling Ford’s Nanchang facility directly to Chengli’s Suizhou manuf
