## Summary

Transport for London (TfL) has completed the award phase of a procurement process for the title "DLR Thamesmead Extension - Gas Diversion Feasibility Design and Options Study." This contract is related to the gas distribution network industry and is located within the UK, specifically tied to London's strategic infrastructure. The process was conducted through a direct award, with Cadent Gas Limited being the sole supplier due to its status as a statutory Gas Distribution Network Operator under the Gas Act 1986. The contract is valued at £1,594,000 with a gross award amount of £1,912,000. The award was scheduled for future signature on 16th June 2026, and the contract period spans from 25th June 2026 to 24th February 2027.

This tender offers substantial opportunities for businesses involved in engineering, feasibility studies, and gas infrastructure, particularly those capable of competing for future sub-contracting opportunities that may arise from this high-profile infrastructure project. Large-scale engineering firms with experience in high, intermediate, and medium-pressure gas mains, as well as those familiar with the statutory requirements associated with gas distribution networks, would be well-suited to engage in further project components. The direct award to Cadent reflects the non-contestable nature of the work; however, collaboration with Cadent or involvement in subsequent project phases could provide business growth opportunities, particularly for businesses skilled in project management, technical interface coordination, and stakeholder engagement.

## Notice

Contract for the provision of a C3 stage feasibility design and options study for potential gas diversion works required to enable the proposed DLR Thamesmead Extension. The current alignment of the Thamesmead Extension (TEx) route intersects a highly strategic and asset-dense section of Statutory Undertaker Cadent's London Network, comprising high, intermediate and medium-pressure gas mains, alongside key installations including the Beckton Above Ground Installation and associated pressure reduction infrastructure. These assets present one of the most significant technical and programme-critical risks to the TEx programme. This request relates solely to the Feasibility Design and Options Study (C3 Works), This phase will provide a comprehensive desktop -based assessment of all potential diversion and AGI rationalisation requirements aligned to the current TEx design. The scope includes options development, engagement of a Cadent-approved design house, initial material take-off assessments, high level cost estimates for later phases, and mobilisation of a dedicated multi-disciplinary project management team to coordinate technical interfaces and third party stakeholders. The estimated value for this contract is PS1,594,000.

### Procurement Information

A Direct Award is required due to the non-contestable nature of the works. As the statutory Gas Distribution Network Operator under the Gas Act 1986, Cadent is the only organisation legally authorised to operate, modify or approve works affecting these assets. Under Procurement Act (PA23) Schedule 5 Clause 5(a)(b), direct awards are permitted where suppliers hold exclusive rights or where competition is objectively absent. No alternative provider can legally undertake or approve the required activities; a direct award is therefore fully compliant and justified.
