Tender Quality Score

This tender for WWD-3 wind turbine gearbox endoscopy services is well-documented and clear, but raises significant fairness concerns due to highly specific experience requirements.

Score Breakdown

Legal Compliance75/100

The tender demonstrates good adherence to basic legal requirements, with a reasonable submission period, appropriate CPV coding, and no detected disputes. The procedure type is coded, indicating a defined process.

Clarity85/100

The tender is exceptionally clear, providing a precise description of services, specific locations, and detailed requirements. Evaluation criteria are unambiguously defined as 100% price-based.

Completeness90/100

All essential information, including title, reference, organization, financial details, timeline, and location, is comprehensively provided. The tender includes a robust set of 10 supporting documents, ensuring thoroughness.

Fairness40/100

While the 100% price-based evaluation is objective and e-procurement is enabled, the requirement for bidders to have experience specifically with "at least three WWD-3 type wind turbine gearboxes" within the last three years is highly restrictive. This specificity significantly limits competition and suggests potential tailoring to a very narrow market or specific providers. The "Value Classified: Yes" despite an estimated value is a minor inconsistency.

•Highly specific technical experience requirement (WWD-3 specific gearboxes).
Practicality70/100

The tender supports electronic submission and clearly specifies the contract duration. Financing information is available. However, an explicit contract start date is not provided.

•Contract start date not explicitly stated.
Data Consistency80/100

Most key fields are consistently populated, and there are no reported suspensions or disputes. Dates are logical and coherent.

•Minor inconsistency between 'Estimated Value: 27,000.00 EUR' and 'Value Classified: Yes'.
Sustainability30/100

The tender does not incorporate any explicit green procurement, social, or innovation criteria. While the service supports renewable energy infrastructure, the procurement process itself does not drive further sustainability objectives.

•Absence of green, social, or innovation criteria.

Strengths

Clear and detailed service description.
Comprehensive supporting documentation.
Transparent 100% price-based evaluation criteria.
Electronic submission and e-procurement enabled.
Good data consistency overall.

Concerns

Highly restrictive technical experience requirement (WWD-3 specific).
Lack of explicit sustainability criteria (green, social, innovation).
Minor inconsistency regarding value classification.
Absence of explicit contract start date.

Recommendations

1. Broaden technical experience requirements to allow for comparable wind turbine gearbox experience, rather than strictly WWD-3 specific, to foster greater competition.
2. Integrate sustainability criteria, such as environmental impact of tools/materials or social responsibility aspects, into future tenders.
3. Clarify the 'Value Classified' status if an estimated value is already provided.
