Tender Quality Score

This tender demonstrates good overall quality with comprehensive documentation and clear requirements, though minor inconsistencies in data and a lack of sustainability focus are noted.

Score Breakdown

Legal Compliance85/100

The tender appears largely compliant with national regulations, featuring a reasonable submission period, a clearly defined simplified procedure, and no detected disputes. Mandatory disclosure requirements are met. The CPV code is acceptable, though potentially broad.

Clarity85/100

The tender description is clear, and requirements are well-documented and understandable, categorized effectively by AI. Evaluation criteria are explicitly defined as 'lowest price is best' in the relevant document, clarifying the initial 'relative_weighting' characteristic. Performance conditions are clearly referenced.

Completeness90/100

All essential basic information, financial details, timelines, and location data are provided. The tender includes a comprehensive set of 10 documents, covering technical specifications, contract drafts, and submission forms, ensuring all necessary information is available to bidders.

Fairness80/100

The tender promotes fairness through disclosed value, reasonable deadlines, objective 'lowest price is best' evaluation criteria, and e-procurement. The requirement for specific prior experience (two contracts worth 30,000 EUR in 3 years) is somewhat restrictive but likely justified for specialized industrial supplies, not indicating tailoring to a specific company.

Practicality70/100

Electronic submission is supported, and the contract start date is known. Financing information is referenced. However, the explicit contract duration is not stated, only the tender validity, which is a minor practical omission for long-term planning.

•Contract duration not explicitly stated
Data Consistency65/100

Most key fields are populated, and dates are logical. However, there is a direct contradiction between the 'Estimated Value: 65,000.00 EUR' and 'Value Classified: Yes' fields. A minor inconsistency exists between 'Evaluation Criteria: relative_weighting' and the more specific 'lowest price is best' method.

•Contradiction between disclosed estimated value and 'Value Classified: Yes'
•Minor inconsistency in evaluation criteria description
Sustainability20/100

The tender does not include any explicit green procurement, social aspects, or innovation focus criteria. It is also not EU funded, which often correlates with higher sustainability standards.

•No explicit green procurement criteria
•No social aspects included

Strengths

Comprehensive documentation provided
Clear and objective evaluation criteria ('lowest price is best')
Electronic submission and e-procurement enabled
Reasonable submission deadline
Detailed AI-extracted requirements

Concerns

Contradiction regarding value classification (disclosed vs. classified)
Lack of explicit contract duration
Specific experience requirement might limit competition
Absence of sustainability, social, or innovation criteria

Recommendations

1. Clarify the 'Value Classified' status to align with the disclosed estimated value.
2. Explicitly state the intended contract duration.
3. Consider adding sustainability or social responsibility clauses where applicable.
