Tender Quality Score

This tender is conceptually well-structured with strong sustainability requirements, but its transparency and accessibility for bidders are severely hampered by the complete absence of essential tender documents.

Score Breakdown

Legal Compliance100/100

Mandatory exclusion grounds and conflict of interest declarations are included, aligning with legal principles. However, the complete lack of full tender documents, missing evaluation criteria, and absence of e-submission pose significant legal compliance risks, hindering transparency and fair competition.

•Restricted document access
•Missing evaluation criteria
Clarity40/100

The project description and scope of work are generally clear, detailing combined design and construction with specific energy and CO2 reduction targets. However, the absence of full tender documents prevents a comprehensive assessment of detailed specifications, drawings, and contract terms.

•Lack of full tender documents prevents comprehensive clarity assessment
•Truncated extracted requirements ('The') suggest incomplete information
Completeness83/100

Basic information, financial details, timeline, and a description are provided. Key eligibility and technical capability requirements are outlined. However, the tender is severely incomplete due to the complete absence of attached documents and missing evaluation criteria, which are fundamental components.

•No documents attached
•No document content available
Fairness60/100

The requirement for prior experience of at least one combined design, construction, and author supervision contract valued at 260,000 EUR (excl. VAT) is very close to the estimated value of 262,805.00 EUR. This threshold is quite high relative to the project's estimated value and could disproportionately limit participation from smaller or medium-sized companies, potentially reducing competition.

•Experience requirement (260,000 EUR) is very close to the estimated value (262,805.00 EUR), potentially limiting competition
Practicality40/100

The project duration of 24 months, with 12 months for design, seems reasonable for a combined design and build project. The requirement for an on-site inspection is practical and necessary. However, the lack of full documents significantly impedes bidders' ability to practically prepare a comprehensive offer.

•Lack of full tender documents significantly impedes practical bid preparation
Data Consistency100/100

The title, description, and requirements consistently refer to the same project scope. The experience requirement value is consistent with the estimated project value. The automated check's 'Not green procurement' flag contradicts the explicit sustainability requirements.

•Automated check's 'Not green procurement' flag is inconsistent with detailed sustainability requirements
Sustainability25/100

The tender explicitly integrates strong sustainability requirements, including specific energy efficiency (7240 kWh/year electricity reduction) and CO2 reduction targets (0.532 t CO2/year emission reduction). It also mandates consideration of climate change impact mitigation, resilience, durable materials, and prevention of issues due to extreme weather, which are excellent green procurement practices.

Strengths

Clear integration of specific energy efficiency and CO2 reduction targets
Mandatory consideration of climate change impact mitigation and resilience in design
Combined design and build approach for efficiency
Requirement for on-site inspection ensures bidder understanding
Mandatory exclusion grounds and conflict of interest declarations

Concerns

Complete absence of tender documents and content, severely hindering transparency and bid preparation
Missing evaluation criteria, making it impossible to understand how offers will be judged
Experience requirement (260,000 EUR) is very close to the estimated value (262,805.00 EUR), potentially limiting competition
Restricted document access and no e-submission, indicating potential procedural shortcomings
Truncated extracted requirements ('The') suggest incomplete information provided for analysis

Recommendations

1. Immediately publish all tender documents, including detailed specifications, drawings, and evaluation criteria, to ensure transparency and fair competition.
2. Re-evaluate the experience requirement threshold to potentially broaden the pool of eligible bidders without compromising quality.
3. Ensure the procurement process supports e-submission for efficiency and accessibility.
