Tender Quality Score

This tender for wind farm maintenance demonstrates good clarity and comprehensive documentation, but raises significant concerns regarding fairness due to highly specific technical experience requirements and notable gaps in contract duration information.

Score Breakdown

Legal Compliance75/100

The tender largely complies with legal requirements, featuring reasonable deadlines, appropriate CPV codes, and adherence to EU/national regulations regarding exclusion grounds and ethical conduct. However, the procedure type is vaguely defined as 'A (Code: N/A)'.

•Vague procedure type code (N/A)
Clarity80/100

The tender description is clear, and requirements are well-documented and understandable, supported by detailed AI-extracted information. Evaluation criteria are specified in a dedicated document, though the automated check flagged them as missing, which might indicate they are not universally clear for all parts or not in the main notice.

•Potential ambiguity regarding the universal application of evaluation criteria across all tender parts
Completeness65/100

While basic information, value, and deadlines are provided, a critical omission is the explicit contract duration. Location information is implicitly given by wind farm names but not in a structured field, and the NUTS code is missing.

•Missing explicit contract duration
•Missing NUTS code
Fairness30/100

The tender's fairness is significantly compromised by the highly specific technical capability requirement for experience with 'at least ten Enercon E-40 (or newer) wind turbines within the last 36 months.' This requirement is likely to severely limit competition to a very narrow pool of specialized bidders, potentially favoring an incumbent or specific manufacturer-aligned companies.

•Highly specific technical requirement (Enercon turbine experience) suggests potential tailoring
Practicality60/100

Electronic submission is supported, which is practical. However, the absence of a clear contract start date and duration poses practical challenges for bidders in planning resources and commitments. Financing information is available in draft contracts.

•Missing explicit contract start date and duration
Data Consistency70/100

Most key fields are populated, and dates are logical. However, the NUTS code is missing, the procedure code is 'N/A', and there's a discrepancy regarding the explicit presence of evaluation criteria (flagged as missing by automated checks, but a document summary indicates their existence).

•Missing NUTS code
•'N/A' for procedure code
Sustainability50/100

While the tender concerns maintenance of wind farms, which are inherently green, the tender documentation itself does not explicitly incorporate additional green procurement criteria, social aspects, or a strong innovation focus beyond a general code of ethics and a clause for SCADA replacement.

•Lack of explicit green, social, or innovation criteria within the tender requirements

Strengths

Clear description of services and division into parts
Comprehensive set of supporting documents and forms
Electronic submission and e-procurement enabled
Value disclosed and reasonable submission deadline
Explicit evaluation criteria (for at least one part)

Concerns

Highly specific technical experience requirement (Enercon turbines) potentially limiting competition
Missing explicit contract duration and start date
Vague procedure type code ('N/A')
Lack of explicit green, social, or innovation criteria
Potential for evaluation criteria not being universally clear for all parts

Recommendations

1. Revise technical requirements to be more generic and performance-based to encourage broader competition.
2. Clearly state the contract duration and anticipated start date in the main tender notice.
3. Explicitly define the procurement procedure type and consider integrating specific sustainability criteria.
