Tender Quality Score

This tender for cucumber greenhouse construction is largely clear and comprehensive, benefiting from EU funding and electronic submission. However, specific brand requirements for lighting and a high turnover threshold raise significant concerns regarding fairness and competition.

Score Breakdown

Legal Compliance85/100

The tender demonstrates good legal compliance with reasonable deadlines, appropriate CPV codes, and a clearly defined procedure type (MS - negotiated procedure). It is EU-funded, implying adherence to relevant regulations, and mandatory disclosures are met. No disputes or suspensions are noted.

Clarity90/100

The project description is highly detailed and unambiguous, clearly outlining the scope and location. Requirements, evaluation criteria (with clear weightings for cost, consultant experience, lighting, and moisture collection), and performance conditions are all exceptionally well-documented and easy to understand.

Completeness90/100

All essential information, including basic details, financial data, timeline, and location, is provided. A comprehensive set of 10 tender documents is listed, covering all necessary aspects for bidders, such as qualification criteria, technical specifications, and submission forms.

Fairness40/100

A major concern is the requirement to specify Philips or Bloemteknik lighting, which is brand-specific and severely restricts competition, potentially favoring specific suppliers or contractors. Additionally, the high net turnover requirement (€3M in the greenhouse sector) may unduly limit participation from smaller, capable firms, impacting equal access.

•Brand-specific requirement for lighting (Philips or Bloemteknik)
•High net turnover requirement (€3M) potentially limiting competition
Practicality80/100

The tender supports electronic submission and e-procurement, enhancing accessibility for bidders. The contract duration is clearly specified (8 months), and financing from EU sources (PRIA) is indicated, providing clarity on funding. While a specific contract start date is not given, the duration is clear.

Data Consistency65/100

While most data fields are populated and dates are logical, there is a notable inconsistency where the estimated value is disclosed (€4,000,000.00) but simultaneously flagged as 'Value Classified: Yes.' The 'Type: E' code is also somewhat ambiguous without further context.

•Inconsistency: Estimated value disclosed but flagged as 'Value Classified: Yes'
•Ambiguous 'Type: E' code
Sustainability35/100

Despite being EU-funded, the tender explicitly lacks specific criteria for green procurement, social aspects, or innovation focus, as confirmed by automated checks. This indicates a missed opportunity to integrate broader sustainability objectives into the procurement process.

•No explicit green procurement criteria
•No explicit social criteria

Strengths

Clear and detailed project description
Comprehensive and weighted evaluation criteria
EU-funded project with electronic submission
Extensive list of supporting tender documents
Reasonable submission deadline

Concerns

Brand-specific requirement for lighting (Philips or Bloemteknik)
High financial qualification threshold (€3M net turnover)
Lack of explicit green, social, or innovation sustainability criteria
Inconsistency in value classification (disclosed vs. classified)

Recommendations

1. Remove brand-specific requirements for lighting or provide objective, performance-based justifications to ensure broader competition.
2. Review financial qualification thresholds to ensure they are proportionate and do not unduly restrict participation from competent smaller firms.
3. Integrate explicit green and social procurement criteria to align with broader EU sustainability goals, especially given its EU funding.
