Tender documents for non-standard assembly lines consist of a “triad” of technical specifications, bid evaluation methods, and commercial terms (Source: Industry practice): Scoring: Price 50 + Commercial 20 + Technical 30 (Source: Anqing); Core: ★Terms (deviations) not to exceed 15% (Source: China Project Network)—Principle: Clearly state the benchmark price calculation method and itemized pricing (Source: Industry insights).
I.
Document Structure
Tender Announcement: Project overview + qualification requirements; Instructions to Bidders: Bid bond + 90-day validity period (Source: National Public Resource Platform); Technical Specifications: Cycle time/workstations/standards (Source: China Project Network); Bid Evaluation Method: Comprehensive evaluation method (Source: Binhai); Contract Terms: Acceptance, payment, and breach of contract—Structure: Announcement + Instructions + Specifications + Evaluation (five-part set).
II.
Bid Evaluation Method
Weighting: Price 50 + Commercial 20 + Technical 30 (Source: Anqing); Benchmark Price: Average of all valid bids (Source: Anqing); Floating Range: Average calculated after excluding the highest and lowest 15% of bids (Source: China Project Network); Price Score: (Benchmark Price ÷ Bid Price) × Weight × 100 (Source: China Project Network); Separation of Evaluation and Award: Bid evaluation and contract award are separate processes (Source: Lianyungang)—Evaluation: Comprehensive assessment + floating range (to prevent low-price bid rigging).
III. Technical Specifications
Cycle Time: Parts per minute; Process: Operational workflow; Standards: National/Industry standards; Configuration: Brands of core components; ★Clause: Deviation not to exceed 15% of technical terms (Source: China Project Network)—Specifications: Cycle time + Process + Standards (quantifiable and verifiable).
IV.
Commercial Terms
Payment Method: Percentage at payment milestones (Source: Government Procurement Network); Itemized Pricing: Separate quotes for capital cost, installation, training, and spare parts (no bundling) (Source: iFactory); Security Deposit: Bid bond (Source: National Public Resource Platform); Confidentiality: Confidentiality commitment (Source: Government Procurement Network); After-sales Service: Return/exchange process (weighted at 5 points) (Source: Longgang)—Commercial: Itemized pricing + Payment + After-sales (listed item by item).
V.
Qualification Requirements
Post-qualification Review: Review prior to bid evaluation (Source: Sheyang); Qualifications: Consistency with business license (Source: Binhai); Track Record: Proof of similar projects; Signatures & Seals: Power of attorney from legal representative (Source: Binhai); Insurance: Product liability insurance—Qualifications: Post-review + Qualifications + Track record (clear thresholds).
VI.
Pitfalls to Avoid
★Excessive Specifications: Over-specification leads to allegations of exclusionary practices (Source: China Project Network); Bundled Pricing: Prevents price comparison; Vague Acceptance Criteria: Lack of FAT/SAT standards; Low-price Trap: Malicious low-price competition (Source: China Project Network); Invalid Bids: Late submissions not accepted (Source: Sheyang)—Avoidance: ★15% limit + Itemized pricing (clearly defined rules).
7. Procurement Recommendations
1. Five-part package (complete structure); 2. Comprehensive evaluation (50/20/30 weighting); 3. Benchmark price range; 4. Itemized pricing;
5. Acceptance standards (FAT/SAT)—Tendering: Specifications, evaluation criteria, and commercial terms (locked across all three dimensions).
