Tender Quality Score

This tender for window cleaning services provides clear service descriptions and requirements but suffers from significant gaps in critical information, notably the absence of evaluation criteria and the failure to access the main Tender Notice document. The lack of e-submission and sustainability considerations also detract from its overall quality.

Score Breakdown

Legal Compliance75/100

The procedure type and CPV codes are clearly defined. However, the absence of specified mandatory exclusion grounds in the AI summary and the failed download of the primary Tender Notice document, which could contain crucial legal information, are concerning.

Absence of specified mandatory exclusion grounds
Failed download of 'Tender Notice' document
Clarity80/100

The description of services and requirements is clear and understandable. However, the explicit absence of evaluation criteria is a significant clarity flaw, hindering bidders from effectively preparing their submissions.
