DLR Thamesmead Extension - Major Project Delivery

Transport for London ("TfL") has commenced Preliminary Market Engagement ("PME") in respect of the proposed DLR Thamesmead Extension ("TEX") Programme. The intention is to establish appetite and to harness expertise from the industry to help develop a suitable strategy for delivering all the works comprised in this Programme.

The initial pre-procurement strategy at this stage anticipates a multi-stage procurement process with an early contractor involvement. To prepare the TEX Programme procurement strategy, TfL is seeking contributions from suppliers with experience in delivering works of a similar magnitude (scale and complexity) to that of the TEX Programme to assist in developing a suitable delivery model for delivering the works. In this respect, advice and suggestions on general buildability of the scheme, concept design, phasing, packaging and sequencing of works, contractual arrangements for the work packages will be invaluable to TfL.

TfL has embarked on implementing a new delivery model to drive improvement, capture construction efficiencies to reduce cost, is seeking innovative techniques to reduce carbon to meet the net zero gain and improve whole life costs.

Industry Engagement

Development of the TfL Delivery Model has been supported by an Industry Day held on 2 December 2025 and a subsequent Market Sounding Questionnaire (MSQ) in accordance with 'UK2: Preliminary market engagement notice - Procurement Act 2023 2025/S 000-071722 6 November 2025'. A summary output from this will be shared with the all PME participants.

This UK2 notice is being published to confirm the next stages of preliminary market engagement. This includes a further Industry Day to be held on 25 February 2026 and a MSQ to focus on the commercial and contracting model. TfL may opt to subsequently hold one-to-one sessions with a selection suppliers having the capability and experience for the scope of works or delivery model. Further details on timeframes and registration are provided below.
