Original Tender Description

Thames Water is seeking to significantly improve its ability to detect leakage and bursts across its trunk mains network, where current monitoring coverage remains limited. This lack of visibility restricts early detection and response, increasing the risk of water loss, asset failure, and service disruption. To address this, Thames Water intends to roll out a Distributed Acoustic Sensing (DAS) fibre sensing solution, with the ambition of achieving near-100% coverage across its trunk mains estate. DAS technology offers the potential to transform network monitoring by converting fibre optic cables into thousands of acoustic sensors, enabling continuous, real-time detection of leaks, bursts, and third-party interference over long distances. The solution must be scalable, cost-effective, and capable of integrating with Thames Water's existing systems and operational workflows. Thames Water is interested in identifying potential service providers who can propose solutions that directly address this challenge. Providers will need to demonstrate how their approach will deliver reliable coverage, actionable insights, and long-term value. Key considerations include deployment strategy, data quality, system integration, and support for future enhancements in predictive maintenance and leakage reduction. The successful partner(s) will play a critical role in helping Thames Water achieve its strategic goal of near-total trunk main monitoring coverage through fibre sensing. Thames Water reserves the right to refine the award criteria. Please note that that deadline for asking for access to the PSQ & submitting of the PSQ is Thursday 19 March at 10 am.

Tender Quality Score

This tender for a DAS fibre sensing solution is generally well-structured with clear technical requirements and a disclosed value. However, it lacks explicit evaluation criteria and details on the submission process beyond the PSQ deadline, impacting overall transparency and practicality.

Score Breakdown

Legal Compliance75/100

The tender appears to comply with general procurement regulations, including a proper CPV code and a stated procedure. The deadlines, while potentially tight for full document review, are present. No disputes are noted. The primary concern is the lack of explicitly stated award criteria, which is a significant omission for legal compliance in a competitive tender.

Missing award criteria
Clarity80/100

The description of the need for a DAS fibre sensing solution is clear and detailed, outlining the problem and the desired outcome. Technical requirements are well-defined, and the objective is understandable. However, the absence of specific evaluation criteria leaves some ambiguity regarding how proposals will be judged.

No evaluation criteria specified
Completeness70/100

Most basic information is present, including title, organization, estimated value, and contract duration. The CPV code is provided. However, the crucial tender documents are not accessible or summarized, and the absence of explicit evaluation criteria hinders completeness. The PSQ deadline is also very early relative to the main submission deadline, which could be a point of confusion.

No document content available
Missing award criteria
Fairness85/100

The tender discloses the estimated value and uses a competitive procedure, which promotes fairness. The requirements are focused on technical capabilities and problem-solving, not tailored to specific companies. Access to the PSQ is mentioned, but the lack of accessible full tender documents and explicit evaluation criteria could be perceived as a barrier to full transparency for all potential bidders.

Practicality65/100

The tender specifies a contract start date that coincides with the submission deadline, which is highly impractical. The lack of information on e-submission methods and the unavailability of tender documents make the practical steps for participation unclear. The early PSQ deadline also adds complexity.

Contract start date coincides with submission deadline
No e-submission specified
Data Consistency90/100

Key fields such as title, reference, organization, value, and deadlines are populated. The contract duration and start date are specified. There are no reported disputes or suspensions. The dates provided are logical, although the contract start date is problematic in practice.

Sustainability50/100

The tender does not explicitly mention any green procurement, social aspects, or innovation criteria. It is also not indicated as EU funded. This suggests a lack of focus on sustainability in the procurement process.

Not green procurement
No social criteria

Strengths

Clear description of need and technical requirements
Disclosed estimated value and CPV code
