Tender Quality Score

This tender outlines a significant framework for sustainable drainage and habitat restoration, demonstrating strong environmental focus and good data consistency, but suffers from a lack of detailed requirements, missing evaluation criteria, and the absence of e-submission.

Score Breakdown

Legal Compliance75/100

The tender defines the procedure type and CPV codes appropriately, and there are no reported disputes. However, the AI-extracted requirements frequently defer to 'full tender documents' for legal specifics, and the 'missing reveal date' is a minor transparency flag.

Reliance on 'full tender documents' for specific legal compliance details
Missing reveal date
Clarity60/100

The overall objective and lot structure are clear. However, the AI-extracted requirements lack specific details, consistently referring to 'full tender documents' for elaboration. Critically, the absence of specified evaluation criteria significantly reduces the clarity for potential bidders.

Missing detailed evaluation criteria
AI-extracted requirements defer to 'full tender documents' for specifics
Completeness65/100

Basic information such as title, reference, organization, value, duration, and CPV codes are well-provided. However, the tender is incomplete regarding detailed requirements and, most notably, the absence of evaluation criteria, which are essential for a comprehensive bid.

Missing detailed evaluation criteria
Detailed requirements are not fully provided, deferring to external documents
Fairness55/100

The disclosed value and multi-lot structure contribute positively to fairness. However, the implied lack of full document access (as AI-extracted requirements defer to them), the critical absence of evaluation criteria, and the lack of e-submission significantly hinder transparency and equal access for all bidders.

Implied lack of full detailed tender document access
Missing detailed evaluation criteria
Practicality60/100

The contract start date and duration are clearly specified. However, the absence of an electronic submission option is a significant practical drawback in modern procurement, potentially increasing administrative burden for bidders.

No electronic submission option
Data Consistency95/100

All key fields are populated, and the data provided is highly consistent across different sections, including financial values and timeline details. There are no reported suspensions or disputes, indicating a stable tender record.

Sustainability75/100

The tender's core subject matter, 'Sustainable Drainage and Habitat Restoration,' inherently demonstrates a strong environmental focus, including biodiversity and SuDS. However, it lacks explicit mention of social aspects or innovation criteria, and it is not EU funded, which often drives higher sustainability standards.

No explicit social criteria mentioned
No explicit innovation focus mentioned
