Tender Quality Score

This tender for the National Gallery's gallery refurbishment is generally well-structured with a clear scope of works and detailed technical requirements. However, it lacks explicit evaluation criteria and information on sustainability aspects.

Score Breakdown

Legal Compliance75/100

The tender appears to comply with general procurement regulations, including a clear CPV code and a defined procedure. The submission deadline is noted, but its reasonableness for a project of this scale and complexity is not explicitly assessed here. No disputes are reported. The absence of a reveal date is a minor procedural oversight.

Missing reveal date
Clarity80/100

The description of the works is comprehensive and detailed, outlining specific technical requirements for refurbishment and environmental control. The AI-extracted technical capabilities further clarify the expected expertise. However, the absence of specified evaluation criteria leaves some ambiguity on how bids will be assessed.

No evaluation criteria specified
Completeness70/100

Most basic information is present, including title, reference, organization, estimated value, and contract duration. The scope of works is detailed. However, the crucial aspect of available tender documents is problematic, with no content or summaries provided, significantly impacting completeness.

No document content available
Fairness85/100

The tender appears fair, with a disclosed value and objective technical requirements derived from the project scope. The procedure is competitive. There are no apparent requirements tailored to specific companies. The lack of explicit evaluation criteria could be perceived as a minor fairness concern, but the detailed technical requirements mitigate this.

Practicality65/100

The tender specifies a contract start date that coincides with the submission deadline, which is impractical. The lack of information regarding e-submission and the absence of a document URL for accessing tender documents hinder practical engagement. Financing information is not detailed.

Contract start date coincides with submission deadline
No e-submission specified
Data Consistency90/100

Key fields such as title, reference, organization, estimated value, CPV code, and contract duration are populated logically. Dates are consistent, although the contract start date is problematic in relation to the submission deadline. No suspension or disputes are reported, contributing to high data consistency.

Sustainability50/100

The tender does not explicitly mention any green procurement, social aspects, or innovation focus. It is also not indicated as EU funded, which often implies adherence to certain sustainability standards. This lack of focus results in a moderate score.

Not green procurement
No social criteria
