Summary of the contracting process

Transport for London commissioned a feasibility design and options study for gas diversion works needed to support the proposed Docklands Light Railway Thamesmead Extension. The work covers a C3-stage, desktop-based assessment of diversion and above-ground installation rationalisation requirements where the proposed route intersects Cadent’s strategic London gas network. Scope includes developing options, engaging a Cadent-approved design house, preparing initial material take-offs and high-level cost estimates for later phases, and mobilising a multidisciplinary project management team to coordinate technical interfaces and third-party stakeholders. The requirement concerns gas-distribution infrastructure and feasibility, advisory and analytical services. Delivery relates to the Thamesmead Extension route and the affected gas assets in London, including the Beckton Above Ground Installation and associated pressure-reduction infrastructure.

The procurement is complete and awarded under a single lot. Transport for London used a direct award for utilities services because the requirement was treated as non-contestable: Cadent Gas Limited is the statutory gas distribution network operator responsible for operating, modifying or approving work affecting these assets, and the stated legal basis was Procurement Act 2023 Schedule 5, clause 5(a) and (b). The award was made to Cadent Gas Limited on 3 August 2026. The contract was signed on 6 May 2026 and runs from 14 August 2026 to 24 February 2027. Its value is £1,594,000 excluding VAT, or £1,912,000 including VAT. The award and contract are active, while the tender is complete.

This procurement demonstrates demand from Transport for London for specialist gas-network interface work supporting major transport infrastructure. It is most relevant to statutory gas distribution network operators and organisations with legal authority over affected gas assets, rather than general engineering consultancies or independent feasibility providers. Credible participants in any comparable requirement would need demonstrable control of, or approval rights over, high-, intermediate- and medium-pressure mains, above-ground installations and pressure-reduction infrastructure. They would also need capability in C3 feasibility design, options appraisal, desktop asset assessment, material take-offs, high-level cost estimating and multidisciplinary project management. Experience coordinating transport-project interfaces, third-party stakeholders and an approved design house would strengthen their position. The direct-award rationale indicates that exclusive statutory rights and the ability to approve the required works are decisive commercial qualifications.

Notice Description

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.

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 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.
