Tender Quality Score

This tender outlines a significant Dynamic Purchasing System and Framework Agreement for gas network infrastructure works. While the scope of works is detailed, the initial notice suffers from a critical lack of comprehensive documentation and specific criteria, hindering a full understanding of the procurement process and requirements.

Score Breakdown

Legal Compliance100/100

The tender mentions mandatory exclusion grounds, aligning with public procurement regulations. However, the absence of full procurement documents and specific admission/evaluation criteria in this initial notice makes it impossible to fully assess compliance with transparency and equal treatment principles at this stage. The restricted procedure for the DPS is noted.

Lack of full procurement documents.
Absence of specific admission and evaluation criteria in the initial notice.
Clarity40/100

The description of the work packages and technical capabilities is generally clear and detailed, defining the scope well. However, the relationship between the Framework Agreement and the DPS, particularly the DPS being 'put in place prior to award of the Framework Agreements,' is somewhat ambiguous. The truncated description for IP works and submission requirements also reduces clarity.

Ambiguous relationship between the Framework Agreement and the Dynamic Purchasing System (DPS).
Truncated description for Intermediate Pressure (IP) works.
Completeness83/100

This initial notice is significantly incomplete. Crucial information such as full procurement documents, specific financial requirements (beyond a general statement of capacity), detailed admission criteria for the DPS, and evaluation criteria are entirely missing. The NUTS code is also absent, and parts of the description and requirements are truncated.

No procurement documents attached or available.
Missing specific financial requirements.
Fairness60/100

The lack of detailed admission and evaluation criteria, coupled with the absence of full procurement documents, creates a significant risk to fairness and equal treatment. Potential suppliers cannot fully understand the basis on which they will be assessed, which could disadvantage smaller or less experienced bidders who require clear guidance. The highly specialized technical requirements, while necessary for the work, could limit competition, but do not inherently suggest tailoring without further context.

Absence of detailed admission and evaluation criteria.
Lack of full procurement documents prevents transparent understanding of the process.
Practicality40/100

The structure of a DPS allows for flexibility and continuous admission of new suppliers, which is practical for long-term, ongoing works. The clear lotting by geographical region (Southern UK and Scotland) is also practical for operational delivery. However, the lack of initial documentation makes it impractical for suppliers to prepare a comprehensive expression of interest or understand the full commitment required.

Lack of initial documentation makes it difficult for suppliers to prepare adequately.
Data Consistency100/100

The provided data is generally consistent within itself, with the estimated value aligning with the scope of works described. However, the truncation of text in the description and requirements sections indicates an issue with the data extraction or presentation, rather than an inconsistency in the tender's content itself.

Truncated text in the description and requirements sections.
Sustainability0/100

The tender notice does not include any explicit mention of green procurement, social criteria, or innovation focus. This indicates a missed opportunity to integrate sustainability objectives into a significant public works contract.

No mention of green procurement criteria.
No mention of social criteria.

Strengths

Clear definition of technical scope and work packages.
Use of a Dynamic Purchasing System for flexibility and continuous supplier admission.
Geographical lotting for efficient delivery.
Significant estimated value indicates a substantial opportunity.
Clear organization and reference details.

Concerns

Absence of full procurement documents and detailed criteria.
Lack of specific financial requirements.
Ambiguity regarding the relationship between the Framework Agreement and DPS.
Truncated descriptions and requirements.
No explicit sustainability, social, or innovation criteria.

Recommendations

1. Publish full procurement documents immediately, detailing all admission, selection, and evaluation criteria.
2. Clarify the exact relationship and timeline between the Framework Agreement and the Dynamic Purchasing System.
3. Integrate clear sustainability, social, and innovation criteria into the tender documents.
